Chronic bloating of the stomach may be gastric flatulence, small intestinal flatulence, colonic flatulence, etc. In addition to stomach flatulence, there may be accompanying symptoms such as burping a lot and farting a lot.

If unfortunately occur in some public places, will be particularly embarrassing, but also seriously affect the image of the gods and goddesses; left unchecked, these "small problems" may be dragged into "big problems", or even serious diseases or even cancer.

Therefore, bloating, which can be a big or small problem, must be taken seriously.

So what's with the bloating?

Let @Registered Dietitian Malt to tell you about it, Malt once because of curiosity, carefully studied, all kinds of trivia about the gastrointestinal tract gas, you will be able to find in this practical knowledge, you happen to have flatulence, burping more, farting more of these related symptoms, the most likely cause.

Body Gas Trivia and Common Causes of Flatulence.

Humans depend on air to live, and it's all too normal for gases to be in and out of our bodies, in and out.

Our food, which also contains a lot of carbon, hydrogen and oxygen, is also constantly producing gas through our intestinal digestion and metabolism by our intestinal flora.

1. Gas components in the gastrointestinal tract

Five gases, nitrogen (N2), oxygen (O2), carbon dioxide (CO2), hydrogen (H2), and methane (CH4), account for more than 99% of the gastrointestinal gases excreted.

The composition of the gas expelled from each area within the gastrointestinal tract also varies. For example, the gas in the stomach has a higher concentration of nitrogen and oxygen, which is closer to air, whereas anal excretion is low in oxygen but high in methane.

The gases we exhale are mainly nitrogen, oxygen and carbon dioxide, with nitrogen being the most abundant, oxygen being the next most abundant, and carbon dioxide inhaled in the air, with gas exchange occurring in the alveoli, so not much is exhaled.

The 5 main gases are all without special odor, so usually exhaled gas and burped gas, are not smelly, and the anal exhaust in the trace gas components, is the cause of the odor, which is the remaining 1% portion, includes sulfur-containing compounds such as methyl mercaptan, dimethyl sulfide, and hydrogen sulfide, as well as short-chain fatty acids, fecal odorants, indoles, volatile amines, and ammonia.

2. Amount of gas in the gastrointestinal tract

Is it really too much gas in your gastrointestinal tract when you feel bloated?

Scientists, on an empty stomach and after a meal, measured the total amount of intestinal gas in normal people, as well as people who felt bloated, and the result was that everyoneGas in the intestines, all around 200ML。

So.Whether you're hungry, or after you've eaten a full meal, and whether you feel bloated or not, the total amount of gas in your intestines, is not very different。

Let's look at the stomach again. When we chew or swallow, there is indeed some gas that reaches the stomach along with the food; when we chew gum, betel nut, or smoke cigarettes, there is likewise gas that enters the stomach. Therefore.The amount of gas in the stomach has to do with the diet and lifestyle of each of us。

If we eat and drink normally, we usually don't bring too much gas to our stomach, to our stomach.

if youAlways feel bloated, then you have to check if you have, the following bad habits first：

① Chewing gum and betel nut more frequently;

② Smoking, the more you smoke, the more air enters your stomach;

③Like to eat soup with rice and drink too much soup during meals.

Excluding the influence of bad habits, and then excluding the cause of organic lesions, the stomach usually does not enter into excessive gas.When people feel bloated, it's often because they're too full, not necessarily because they have too much gas.。

3. Stomach gas production and belching (burping)

But why do people have the impression that when they feel bloated, they say "flatulence"? This intuitive impression is mostly due to burping.

Hiccups, medically called belching, are of course gas related.

①Spontaneous belching

It's possible to burp when you're hungry, and also when you're full, What comes out of the burp is of course gas, but this is not necessarily because, there is an increase in gas in the stomach.

You starve your stomach "flat", the stomach contraction, the inside of the gas will naturally be squeezed out; eat too much, with the food into the stomach of the air is also more, when a lot of food, the stomach space is slowly occupied, the gas will of course be squeezed out.

These two conditions, which we call spontaneous belching, are normal physiologic phenomena. Belching (hiccups) is usually more common after a meal, when the stomach expands to release swallowed air.

② Non-spontaneous belching

There is a kind of hiccups, and the stomach has nothing to do with it, belong to the non-spontaneous belching, it is a disease, is a kind of chronic, recurrent air swallowing (aerophagia), caused by a kind of disease, in this case, the air basically only into the esophagus, and then hiccups out of it, did not go into the stomach at all, so it's also called the "gastric belching".

Belching in these patients may become habitual and is often mistaken for a sign of digestive problems; episodes of supragastric belching are more frequent than gastric belching, and the episodes are not confined to before and after meals as is the case with spontaneous belching。

Aerophagia can be a manifestation of anxiety and can be exacerbated by chewing gum and smoking; there are foods that relax the lower esophageal sphincter, such as chocolate, fat, and peppermint, that may promote belching; and a few milliliters of air are swallowed with each normal swallow, but when we take large gulps of food, we swallow a much larger amount of gas.

4. Intestinal gas production and bloating

(1) Sources of major intestinal gases

Three of the five main gases, carbon dioxide, hydrogen, and methane are produced in the intestinal lumen.

carbon dioxide CO2- In the upper gastrointestinal tract (the digestive tract above the duodenum), carbon dioxide may be produced by the digestion of fats and proteins, by bacterial fermentation, or by the action of gastric acid with bicarbonate, although most of the carbon dioxide produced in the upper part of the small intestine may be absorbed before it enters the colon.

The carbon dioxide in anal exhaust, on the other hand, may be produced by bacterial fermentation in the colon. There are specific food components that may cause increased carbon dioxide in anal exhaust, such as indigestible carbohydrates.

hydrogen (gas)- Hydrogen is produced primarily in the colon, butBacterial overgrowth in the small intestineThe exception is when bacterial fermentation in the small intestine produces large amounts of hydrogen.

Carbohydrates and proteins in food are sources of hydrogen production. Malabsorption of carbohydrates in the small intestine can lead to increased carbohydrate levels in the colon, which can increase hydrogen production.

So diets in which certain oligosaccharides (such as beans, which contain fructose and cotton candy), or certain foods high in resistant starch (such as wheat, oats, potatoes, and corn) are eaten in excess but are not fully digested by the enzymes in the normal small intestine, can also lead to increased production of hydrogen.

Fecal bacteria can both produce and consume hydrogen, and bacteria consume hydrogen when they produce methane, sulfide, and acetate, so the net excretion of hydrogen by the anus is determined by these two processes.

methane CH4- Methane (CH4), can only be produced by bacterial metabolism. The main methane-producing bacteria are Pseudomonas aeruginosa, and in the process of producing methane by these bacteria, the amount of gases (hydrogen and carbon dioxide) that might otherwise be present in the colon is effectively reduced.

Methane may be absorbed into the portal circulation and expelled with exhalation, more often still anally.

The tendency to produce methane is determined by the concentration of methane-producing bacteria in the colon, and may be related to genetic factors as well as environmental factors during the mother's pregnancy and infancy. It has been found that the presence of bile acids in the colon may be important in the regulation of methane production, so that the metabolism of cholesterol also affects methane homeostasis.

When too little methane is produced, too much hydrogen and carbon dioxide may be produced, but the incidence of increased methane production is higher in patients with colorectal cancer, extensive ulcerative colitis, and colon polyps compared to healthy individuals.

It is evident that the amount of gas in the intestines should be in a dynamic equilibrium。The fact is that the amount of gas expelled through the rectum is about 500-1500mL per day, and the frequency of anal exhaust, or farting, in a healthy person is about 10-20 times per day, and in fact, the vast majority of people, even if they feel like they are constantly bloated and farting excessively, usually don't fart more often than that!。

So here's the problem.Compared to people with healthy stomachs and intestines, most people who always feel bloated and fart a lot don't have a significant increase in the amount of gas produced or eliminated from their intestines every day, but why do they actually experience these obviously very uncomfortable symptoms?

(2) Causes of significant bloating and abdominal distension

bloatingrefers to the personal sensation of abdominal fullness, and theAbdominal distension (bulging of the abdomen)Meaning an increase in abdominal circumference that is clearly visible, or for which measurements can be taken.

People often think that the problem must have something to do with the excessive production of intestinal gas, but is this really the case?？

The study found thatPeople who always feel noticeably bloated have significantly delayed small intestinal gas transport compared to healthy people。

For example, in one experiment, 20 patients with irritable bowel syndrome accompanied by severe bloating and 20 healthy individuals were given theIntestinal gas injection, for comparison.It was found that, compared to healthy people, patients with irritable bowel had significant gas retention, increased gastrointestinal symptoms or abdominal distension.。

Then to their duodenums, respectivelyLipid infusionConducting experiments.It was similarly found that in irritable bowel patients, the delay in gas transmission time was more severe than in healthy individuals。

Whereas stimulating these patients with drugs that promote peristalsis in their intestines has been found to, in this way, reduce gas retention and alleviate symptoms, so that theIt was concluded that impaired intestinal motility may be the cause of complaints of bloating in some patients。

It has also been found that there are others who complain of marked abdominal distension and abdominal bulging, who have a relatively strong reaction to even a small increase in gas in the intestinal lumen, which can manifest itself as a downward displacement of the transverse septum, and can often be seen as a result of this, a marked bulging of the abdominal wall, and a downward compression of the thoracic transverse septum, which naturally occurs as a result of the marked abdominal distension.

In contrast, patients with impaired peristalsis during bloating episodes have a greater amount of gas accumulated in the intestinal lumen, which can consequently cause their diaphragm, which is naturally displaced toward their head, to still experience excessive abdominal distension.

As for the mechanisms regulating this displacement of the thoracic septum, they are not fully understood, theIt's probably related to emotions and neural regulation.，Hypersensitivity to increased intestinal gas, however, does trigger abdominal distension and bloating caused by the septum shifting downward and squeezing the abdomen。

There are also a number of patients who are often self-conscious of bloating and the presence ofIntestinal pain hypersensitivitythat manifests itself in increased sensitivity to flatulence or even an overreaction to the movement of normal amounts of gas.It has been found that among patients with chronic bloating, pain response due to bloating is significantly enhanced。

People with a healthier gut may not feel the same pain as those who are often bloated, even if they also experience the same level of bloating. In other words, our bodies automatically sensitize some people to intestinal pain!。

So, there comes the very depressing fact that theThere are just some people who experience bloating without experiencing an excessive increase in intestinal gas, and may also feel much higher levels of pain than the norm。

It is also true that bloating and pain are caused by intestinal gas, such as gas trapped in the liver and spleen flexure of the colon, which is known as thesplenic varicose syndrome (medicine). In this case, there is inflated dilatation and spasm of the intestinal segments close to the hepatic-splenic flexure of the colon, followed by pain.

But again, not because of an increase in total intestinal gas.It's because the gas is concentrated in the area where the colon bends., and very often there is no organic intestinal pathology occurring, but the area, which may be temporarily constricted, becomes narrowed, resulting in gas or fecal retention.

If there is a feeling of swelling or pressure pain in the left upper abdomen, and it occurs mostly when eating or after meals, and the symptom is significantly relieved or disappears after defecation or elimination of gas, it is most likely to be hepatic-splenic flexure syndrome. This condition is often triggered by mood swings, indigestion, and constipation.

Also, there is a bad habit that can lead to a significant increase in small intestinal gas, and thus abdominal bloating, and that bad habit is, theEat and go to bed, or lie down.。

When we are in the supine position, the stomach gas is located above the overlying gastric juices at the gastroesophageal junction, and at this time, the gas tends to preferentially enter the small intestine, theThat is to say, when we lie down, the gas in the stomach, is able to enter the small intestine relatively easily. So.If you spend a lot of time lying down during the day, it's normal to experience abdominal distension。

Especially after eating like to lie down people, more prone to bloating, when eating, with the swallowing of food, the stomach will enter more air than usual, after the meal and then lie down, naturally, there will be a lot of air into the intestinal tract。

Not only do you like to lie down, but you also like to chew gum, chew betel nut, smoke and eat when you lie down, especially pay attention to it, which is the equivalent of their own initiative to the small intestine to fill the air!。

[Malt to summarize]

Common causes of significant bloating and abdominal distension include.

(1) Dysmotility of the intestinal tract, resulting in a significant delay in the rate of gas transport through the small intestine;

(ii) Hypersensitivity to increased intestinal gas causes spontaneous vegetative regulation, which results in downward displacement of the thoracic septum and compression of the abdomen;

(iii) Intestinal nociceptive hypersensitivity, which makes some people highly sensitive to abdominal distension and the resulting pain, thus, in terms of self-perception, aggravating the symptoms;

④ This section of the intestine near the hepatic and splenic flexures of the colon becomes temporarily constricted and narrowed, resulting in the retention of gas or feces.

⑤ A change in position (lying down) that occurs when a large amount of air is swallowed can cause air from the stomach to be instilled into the small intestine.

These are the common causes of flatulence, because of certain diseases (such as bacterial overgrowth in the small intestine, inflammatory bowel disease and peptic ulcers, intestinal cancers, etc.), and other conditions caused by the after-effects of surgeries, which will not be described too much here for you.

Although the total amount of gas produced in the intestines, as well as the amount of gas excreted, can always maintain a dynamic balance, but this does not mean that the ratio of the various gases in the intestines can always be maintained at a stable level, research has found that each person's degree of digestion and absorption of a variety of foods, as well as tolerance is very different, and long-term consumption of intolerant foods, leading to chronic intestinal damage, as well as intestinal flora disorders, may be the gastrointestinal tract The root cause of progressive problems in gastrointestinal function。

Therefore, Malt hopes that you will pay attention to the intervention at the early stage of symptoms, at this time, some of their own dietary and habitual adjustments, usually be able to delay, or even reverse the gastrointestinal dysfunction!。

[Malt talking]

When symptoms of gastrointestinal discomfort first appear, they often start with a single symptom, such as bloating and belching, and the episodes may not be so frequent that they can be easily overlooked.

If left unchecked, gastrointestinal function may gradually deteriorate, disorders, or even organic lesions may occur. Initially, these gastrointestinal problems are usually caused by diet, lifestyle habits, emotions and stress.

Chronic poor eating and living habitsFor example, irregular meal times, eating too fast, pouring too much soup during meals, preferring to lie down after meals or, on the contrary, doing strenuous exercise after meals, lying on the bed, chewing gum, chewing betel nut, and smoking often become direct factors in the development of gastrointestinal symptoms.

discontent, which likewise has a huge impact on the gut. As mentioned in this article, because anxiety may produce swallowing disorders, chronic stress, as well as emotions such as sadness and nervousness during eating, can significantly affect the functioning of the gastrointestinal tract and cause problems with the digestive system's regulatory mechanisms.

Failure to pay attention to adverse reactions to food, often eat food, if on their gastrointestinal tract, will produce some adverse effects (such as food intolerance, food allergies), it may cause chronic damage to the intestinal tract (intestinal mucosal damage, barrier function is destroyed, intestinal permeability increased), leading to the emergence of chronic inflammation, intestinal flora disorders. Carbohydrate intolerance, for example, as also mentioned in this article, increases hydrogen in the gut, and again, flatulence can occur.

Unbalanced diet，Poor dietThe love of meat, heavy oil and salt, like sweets, etc., so that the intestinal flora has also become a single, or flora imbalance, loss of diversity, resulting in intestinal flora disorders, which occurs a series of metabolic disorders, intestinal inflammation, reduce immunity.

How many of these bad habits do you have? They are all possible reasons why the function of the digestive system is getting worse and worse, so make corrections as soon as possible, and develop good eating and living habits that will benefit you for the rest of your life.

[Malt's Warm Tips]

If the following symptoms occur along with bloating, you should seek medical attention:

• Frequent or severe diarrhea
• Unexplained weight loss
• 腹痛
• having blood in one's stool
• loss of appetite
• Unexplained fever
• vomiting

Avoiding the following foods during bloating can reduce the production of intestinal gas and relieve symptoms:

• Milk and dairy products
• legumes
• Certain vegetables: such as kale, broccoli, asparagus, potatoes and corn
• Certain whole grains: e.g. wheat
• Most fruits
• artificial sweetener
• Soda and carbonated beverages
• Chewing gum, betel nut

Not everyone who eats the above foods produces more gas, so it is recommended that you keep a record of your diet in order to identify foods that cause flatulence.。

Digestive disorders must be treated actively to avoid delays, while the health of the stomach and intestines requires you to maintain every day with care.

Dr. Lee is a gastroenterologist at a tertiary care hospital. Let me tell you what's going on with chronic bloating.

Abdominal distension is a pathological condition in which the abdomen is bulging and distended. The most common cause of abdominal distension is the accumulation of gas in the intestinal tubes, and it can also be manifested when the abdominal cavity contains a large amount of fluid.

Let's first look at what happens to bloating due to increased gas in the gastrointestinal tract

Normal people know that our intestines contain a part of the gas, this part of the gas usually maintain a normal state of balance, that is, the gastrointestinal tract to produce gas and discharge gas is basically equal, when this balance is broken, it will be manifested in the gastrointestinal tract gas increases or decreases, the gas increases will be manifested as abdominal distension.

1. Increased gas production. When we eat foods that produce more gas such as garlic, sweet potatoes, potatoes and other foods, this is when the gas inside the intestinal tube increases. If the gastrointestinal flora is imbalanced, the gas-producing bacteria increase, fermenting the food and producing a large amount of gas. In addition, gastrointestinal diseases such as gastritis, enteritis, intestinal polyps, Crohn's disease and other diseases can also lead to an increase in gas production in the intestinal tube. In addition to this, the air in the air can also 'eat' the gas in through our swallowing action can also lead to increased gas production in the intestinal tube.

2, gastrointestinal gas absorption or discharge failure. The human body not only lungs can carry out gas exchange, the intestinal tube can also absorb part of the gas, when the gastrointestinal tract gas absorption dysfunction, the gas inside the intestinal lumen will naturally increase. The excess gas from the gastrointestinal tract is expelled by us in the form of burping or farting. But when if there is a problem with these two channels, it naturally manifests itself as increased gas in the gastrointestinal tract.Intestinal obstruction is a common condition that causes most people to experience an increase in gas in the intestinal tubes, which manifests as bloating.

3. Decrease in peristaltic function of intestines. Normal people's gastrointestinal tract is a 24-hour non-stop peristalsis, when there is a decline in peristalsis and dyspepsia, intestinal peristalsis reduces the ability to defecate and defecate, it will be manifested as abdominal distension. Especially the elderly or long-term bedridden, fiber eating too little of the patient is most likely to appear this situation.

Abdominal fluid is also a cause of bloating

The abdominal cavity of a normal person contains a small amount of fluid, about 50 milliliters or less, and this small amount of fluid is the basis for the normal peristalsis of our intestinal tubes. When this fluid is greater than 200 milliliters, it is called abdominal fluid, and abdominal fluid is a serious pathological condition.

There are many reasons that can cause abdominal fluid, the most common is cirrhosis after the loss of compensatory phase because of the blood human albumin decline, and lead to abdominal fluid, cirrhosis caused by abdominal fluid, Dr. Li clinically see the most 4000-5000ml, like a pregnant woman, with a big belly.

In addition to cirrhosis, which can cause abdominal fluid, kidney disease, peritonitis, tumors, and gastrointestinal perforation can also cause abdominal fluid.

In conclusion, there are many causes of abdominal bloating, when we find ourselves with chronic bloating, first of all, dietary adjustments should be made to avoid eating food with high gas production, maintain daily bowel movements, if there is no improvement, we should go to the doctor immediately to avoid further deterioration of the condition leading to serious consequences.

Flatulence is the medical term for bloating, and prolonged bloating of the stomach is a symptom of a problem with the digestive system, not just a disease. Many diseases of the digestive system can cause flatulence. So it is important to know what causes flatulence in order to prevent and treat it.

What are common causes of flatulence?

1. Gastrointestinal flatulence caused by lesions of digestive organs (including the stomach, intestines, liver, gallbladder and pancreas, etc.).

This includes a big aspect, the most common is caused by gastrointestinal causes, there are gastritis gastric ulcer, gastric function is weakened, indigestion, etc., eat down the things, digestion is not so fast, or eat a difficult to digest food, gathered in the gastrointestinal tract, will also appear in the abdominal bloating.

Overeating, eating too much, difficult to digest, will appear short-term flatulence, appropriate exercise will be improved. Constipation will also appear bloating, the colon gathered a large number of feces excretion can not go out, just eat the digested food can not go down, there is a bloating.

Serious gastrointestinal pathologies such as intestinal obstruction and intestinal perforation can also cause abdominal distension. When symptoms such as abdominal pain and vomiting are accompanied by symptoms other than simple abdominal distension, it is important to go to the hospital, as severe abdominal distension can cause death.

2. Excessive gas production during metabolism of food or drugs。

Bloating occurs when you eat foods that tend to produce gas, such as carbonated beverages, onions, etc., which produce too much gas that collects in the gastrointestinal tract.

3. Intra-abdominal mass or organ peritoneal migration.

Bloating can also occur when something grows in the abdomen and presses on the gastrointestinal tract.

4. Excessive accumulation of fluid in the abdominal cavity.

Here we are talking about hydroperitoneum, various causes of hydroperitoneum, more water in the abdominal cavity, less space, compression of the gastrointestinal tract, abdominal distension can also occur. For example, cirrhosis or malignant tumors cause a lot of ascites.

5. Stress (including psychological, infections, etc.).

Psychological factors also play a role, as people who are chronically depressed, or highly stressed, experience indigestion, which can also cause bloating.

6. Thoracoabdominal effusion caused by other systemic diseases (cardiac, renal, endocrine, neurological, hematologic, etc.).

Bloating can also occur for other systemic reasons.

What should I do about chronic flatulence?

There are many reasons for flatulence, and the first step is to find out what is causing the chronic flatulence. When flatulence occurs, it is important to go to a regular hospital to check the gastrointestinal tract and abdominal cavity for lesions, and if there are lesions, to treat the root cause.

If there is no lesion in the gastrointestinal tract and abdominal cavity, then we should start to improve our living habits and diet, so that we do not overeat, eat less gas-producing food, eat less spicy and irritating food, and exercise appropriately to increase gastrointestinal peristalsis and reduce the accumulation of gas in the gastrointestinal tract.

Chronic bloating of the stomach is medically known as "abdominal distension". Many people almost always ignore this symptom of abdominal distension, in fact, abdominal distension is actually a symptom of many diseases, there are also physiological abdominal distension. Abdominal bloating is the intestinal tube and stomach is too much gas, elimination obstacles, resulting in increased intra-abdominal pressure and cause abdominal bloating.

Abdominal bloating is not alone, often accompanied by burping belching and other symptoms, abdominal bloating causes, there are physiological, there are also pathological, but also some of the drugs taken for a long time will also lead to abdominal bloating.

Below, Kirk popularizes what are the specific causes of bloating?

1, the most common is caused by improper diet, such as overeating, large mouth inhalation, eating some easy to produce gas food (cola, yogurt, soy products), these reasons will lead to excessive gastrointestinal gas production.

2、Diseases of the digestive system, such as hepatitis, gastritis, pyloric obstruction and gastric cancer, pancreatic, bile duct diseases, intra-abdominal tumors, ascites can lead to pathological abdominal distension in the human body.

3, eating some not easy to digest food, there is the gastrointestinal tract peristalsis is weakened, food emptying delay, resulting in a large amount of food gathered in the stomach and intestines, there is also intestinal absorption obstacles, so that constipation, venting obstacles, so it is easy to lead to abdominal distension.

4, mental state stimulation, resulting in human digestive system stimulation makes the gastrointestinal tract reaction absorption and excretion function is abnormal, there is a long-term use of some drugs, resulting in drug metabolism is abnormal, but also easy to lead to abdominal distension.

Therefore, long-term bloating will lead to the human body to appear gastrointestinal tract dysfunction, the emergence of a number of lesions, there is also to lead to the human body nutritional absorption obstacles, malnutrition and other adverse lesions. Treatment of bloating in addition to pay attention to dietary habits but also to treat gastrointestinal motility (morpholine, cisapride, dimethylsilicone oil, probiotics, etc.), and severe cases need timely treatment.

In daily life, everyone may have had such an experience, that is, the stomach bloating phenomenon, although the symptoms are not necessarily obvious, but it is indeed very uncomfortable. If it only occurs for a short period of time, it usually does not affect much, but if it occurs for a long period of time, it is an intolerable thing.

The appearance of flatulence in the stomach is a common symptom of the digestive system, rather than a disease. In the hospital clinic is common in acute and chronic gastritis, peptic ulcer, small intestinal absorption dysfunction, intestinal obstruction, inflammatory bowel disease, intestinal tuberculosis, intestinal tumors and other diseases, so long-term flatulence, you need to go to the hospital Gastroenterology Department to do a professional checkup, the first thing you need to rule out the effect of organic diseases, and then consider whether it is the long-term flatulence caused by some bad behavioral habits in life.

There are some undesirable factors in your regular life that can also lead to chronic flatulence:

First, improper diet, eating too fast, too fast, causing too much swallowing, which is easy to make the intestinal tract to produce too much gas, or exhaust channel is not smooth, will cause flatulence. Usually eat should pay attention to chewing and swallowing slowly, at the same time to eat less easy to cause flatulence food, such as soybeans, groundnuts, sweet potatoes, onions, etc., carbonated beverages should not drink more.

Second, life is not regular, long time rest is not good for the intestinal tract is harmful, which will make the intestinal tract injury, time will aggravate the burden on the stomach and intestines, will also appear flatulence.

Third, caused by Helicobacter pylori infection, if the stomach is infected with Helicobacter pylori, it will affect the gastrointestinal tract's motor function, manifested as delayed gastric emptying and postprandial gastric contraction movement is weakened, so that the gastrointestinal gas excretion is delayed and abdominal distension occurs.

Fourth, improper use of medication, if a long time after taking too much sodium bicarbonate, calcium carbonate and other drugs, will produce carbon dioxide in the stomach leading to bloating. Or after applying a large number of antibiotics, such as the normal bacteria in the intestinal tract is inhibited, after the intestinal flora changes, it will lead to food fermentation and excessive gas production.

When the stomach is bloated for a long time, it is important to pay attention and find out what kind of factors are affecting you so that you can regulate the treatment. Avoid small problems, delayed into a big disease.

Bloating or flatulence, refers to the feeling of fullness in the abdomen, and is a rather vague concept that is difficult to express precisely, some people feel bloated, early satiety, uncomfortable fullness, but also accompanied by hiccups, belching, abdominal ringing.

probability of bloating occurring:

Bloating is a very common problem, with 10 to 30% of the adult population suffering from it. A survey in the United States showed that as much as 16 percentBloating or flatulence was reported, three-quarters of which were moderate to severe.

Causes of bloating:

Causes of bloating, very many

(1) Gastrointestinal causes and disorders associated with bloating.

irritable bowel syndrome.Aerophagia.anorexia and bulimia.Gastroparesis.gastric outlet obstruction/pyloric stenosis.Functional dyspepsia

Dietary factors:lactose or fructose intolerance.intake of fructose, sorbitol, or other non-absorbable sugars.high carbohydrate intake.Gluten Sensitivity.

Celiac disease.Chronic constipation.bacterial overgrowth in the small intestine.abnormal peristalsis of the small intestine (e.g., scleroderma).Diverticulosis of the small intestine.Abnormalities of colonic transport, etc.

(2) Non-gastrointestinal disorders associated with bloating and flatulence

(3) Ascites - e.g. from congestive heart failure, cirrhosis, malignant tumors

(4) Abdominal distension caused by pregnancy and tumors

(5) Bloating during the menstrual cycle may be a normal symptom

Treatment of bloating:

First of all, the cause should be clarified. If the bloating is caused by tumor, cirrhosis, heart failure, or gastrointestinal obstruction, the primary cause should be treated, and the symptoms of bloating can usually be relieved.

For bloating of unknown etiology, or functional bloating, the following can be treated:

(1) Diet.

o Split meals: three meals plus two snacks per day. Smaller meals are preferred. Avoid bedtime snacks.

o Limit your intake of hard-to-digest carbohydrates such as beans, broccoli, cabbage, cauliflower, Brussels sprouts. Instead, eat easily digestible carbohydrates such as potatoes, rice, lettuce, bananas, grapes, and yogurt.

o Avoid caffeinated beverages.

o Avoid foods and beverages that have gas in them. Such as soft drinks and beer.

o Gradually increase dietary fiber over weeks rather than days to allow the body to adapt.

o Consumption of fermented dairy products with probiotics can improve bloating.

o Limit polyol foods-artificial sweeteners such as maltitol, sorbitol, xylitol, isomaltulose.

o Reduce intake of foods high in animal fat, greasy or fried foods.

o Avoid overeating; don't eat quickly, chew slowly.

o Maintain a healthy body mass index and achieve an ideal weight.

Avoid foods that ferment in the stomach (which can cause bloating), as well as starchy foods, cabbage, milk and alcoholic beverages, keeping in mind that any meal should be diversified.

o Recommended Protein: Meals should be given protein and dairy products, reducing sugar and fat intake will improve bloating.

 Lifestyle - Improving Exercise Movement and Posture

 Medication - Over-the-counter medications containing dimethicone and activated charcoal are still used for flatulence and bloating, but their utility is questionable. Some studies of probiotic preparations containing Lactobacillus and Bifidobacterium have reported improvement in bloating and flatulence.

Chronic bloating in the stomach is mostly caused by flatulence in the stomach or in the intestines, and there are several reasons for this:

First, often eat spicy stimulation of cold and greasy things, such as butter hot pot, Guandong Boiled, fried chicken, fat meat, oil splash noodles, cold beer, ice cream, frozen Coke, ice cold Sprite, etc. Because of the above things are difficult to digest, time and then make the stomach and intestines to appear fatigue phenomenon, manifested in the peristalsis of the slow, and ultimately produce too much gas, causing gastrointestinal flatulence, people will feel the stomach more bloated.

Secondly, people who suffer from gastrointestinal diseases will often have bloating, such as: chronic superficial gastritis, chronic atrophic gastritis, gastric ulcer, gastric perforation, etc. Some people who suffer from gastric cancer will also have bloating. Due to the inflammatory reaction of gastric mucosa, it will lead to pathological changes of gastric mucosa such as metamorphosis, exudation, hyperplasia, etc. Metamorphosis and exudation will produce some bacteria and provide some comfortable environment for bacteria, which will lead to the reproduction and proliferation of the bacteria, and these bacteria will corrode the food when they meet the food, ferment the food, which will produce a lot of gases, leading to the gastrointestinal flatulence, making the person feel bloated.

Thirdly, it is caused by the infection of Helicobacter pylori in the gastrointestinal department, as Helicobacter pylori will ferment and produce gas when it encounters food. This leads to gastrointestinal flatulence, which makes you feel bloated and gassy. Although some people infected with Helicobacter pylori will suffer from chronic gastritis, if not actively treated, over time will suffer from gastric ulcers, gastric perforation, gastric cancer and other gastrointestinal diseases, but a large part of the people although found infected with Helicobacter pylori, but in addition to the stomach bloating, there is no uncomfortable symptoms, which a large part of the people who are often taking anti-inflammatory medicines (amoxicillin, roxithromycin, cephalosporins, etc.), to protect the mucous membrane of the stomach of the drug (such as bismuth pectin), but still the stomach is bloated, this is the need to remove H. pylori, you can use triple therapy (other antibiotics such as amoxicillin, bismuth pectin and other drugs to protect the gastric mucosa, cimetidine, ranitidine and other H2-receptor blockers, or lasoprazole and other proton pump inhibitors) or quadruple therapy (cephalosporin antibiotics, potassium citrate, potassium citrate, bismuth pectin and other drugs to protect the gastric mucosa, H2 receptor blockers such as ranitidine or other proton pump inhibitors such as lasoprazole) to get rid of Helicobacter pylori, as long as you take it according to the course of treatment, you can definitely get rid of the bloating.

Fourth, it may be caused by hypothyroidism, that is, the thyroid gland secretes too little thyroxine. As thyroxine can promote gastrointestinal motility, when the thyroid gland secretes too little thyroxine, gastrointestinal motility will be weakened, which in turn leads to gastrointestinal flatulence, making people feel bloated.

Flatulence is actually abdominal distension. As a result of swallowing as well as fermentation of food, a person can probably produce about 500-2000 ml of gas per day, and under normal circumstances, about 100-500 ml of gas in the gastrointestinal tract. These gases must be discharged, such as in the form of belching and farting, etc. Most of the gases in the intestinal lumen are absorbed by the capillaries of the intestinal wall, and a small amount is discharged with the feces, thus maintaining the dynamic balance of gases in the gastrointestinal tract. If too much gas is produced or (and) too little is expelled, it causes what we call flatulence [1,2].

Common causes of bloating are as follows: 1. Eating indigestible food and/or drinking unclean food, resulting in poor digestion and gastrointestinal function or excessive fermentation of food; 2. When the body lacks a lipase enzyme, it cannot digest the fat in dairy products, causing bloating when consuming them; 3. Excessive gas in the body due to consumption of soybean products, grains, cauliflower, or consumption of large quantities of gas-producing beverages; 4. when the body's absorption function is impaired, there will be stomach pain accompanied by weight loss; 5. when suffering from hepatitis, cirrhosis of the liver, abdominal tumors and other diseases and neurosis, abdominal fluid or gas accumulation, causing stomach distension; 6. in the case of a high-fat diet, the gastrointestinal emptying is delayed, which can also cause stomach distension [2].

If stomach bloating does not improve for several days, first of all, adjust your dietary structure and eating habits. Eat less gas-producing food, avoid gas-producing drinks, don't chew gum, less saliva; don't gobble when eating, chew and swallow; more exercise. Secondly, in terms of drug selection, you must be clear about what the cause of your bloating is, and then choose the right drug. For example, if the bloating caused by indigestion can be gastric digestion and digestive enzyme drugs, if the bloating caused by gastric insufficiency can be used to help gastric power drugs to strengthen gastrointestinal peristalsis; if it is a persistent and unexplained bloating, serious abdominal diseases may occur, and should be consulted as soon as possible [2].

In the outpatient clinic, there are often patients who say "their stomach is bloated", after careful inquiry, some patients have nothing to do with diet, and some patients have obvious bloating after meals. Bloating is a self-conscious symptom of the patient, but the doctor can diagnose it through palpation for patients with serious bloating. Our gastrointestinal tract itself has a certain amount of gas, when the gastrointestinal tract is too much gas, more than the total amount of gas it can absorb and expel, we will have the phenomenon of abdominal distension, accompanied by belching, abdominal pain, vectors of gas and other concurrent symptoms, so what are the causes of abdominal distension? Down we come together to understand.

1>Dyspepsia: Long-term disordered rhythm of life, irregular diet, favor some cold stimulation, gastrointestinal stimulation of food, and less exercise, which leads to poor gastrointestinal function and abdominal distension, mostly accompanied by diarrhea, nausea, vomiting and other symptoms.

2> Obstruction of exhaustion: such as intestinal obstruction, in addition to abdominal distension, there will be no defecation, exhaustion, abdominal auscultation can be heard in the weakening or disappearance of intestinal sounds; sometimes there will be colicky pain, accompanied by vomiting manifestations; pyloric obstruction will also appear in this kind of abdominal distension, but the upper abdomen is obvious, you can see the abdomen is obviously puffed up, the vomitus is mostly for the night of the host food.

3> Excessive gas production: can also be seen in some long-term use of broad-spectrum antibiotics in the population, which leads to intestinal flora imbalance, so that anaerobic bacteria overgrowth, the formation of mesenteric thrombosis, so that CO2 will be diffused from the blood into the intestinal tract, intestinal CO2 increase, resulting in increased gastrointestinal gas; some patients with excessive stomach acid and ulcer patients, postprandial saliva, mucus, bile and the pancreatic fluid in the reaction of gastric acid and the production or more CO2. Produce or more CO2.

If you only have occasional bloating, which can be relieved by drinking hot water and using a warm water bag, there is no problem; however, if you have long-term bloating, which cannot be relieved on its own and is accompanied by other digestive manifestations, it is necessary to consult a doctor in a timely manner in order to find out the cause of the problem and treat it appropriately.

Welcome to Apricot Island for more useful health knowledge.

Hello, I am glad to answer your question. In case of prolonged bloating of the stomach, it is important to get it examined on time, due to organic pathology causing bloating.

Children and the elderly in general are prone to gastric distension and bloating, because their gastrointestinal tract peristalsis function is weakened, coupled with the small children spleen and stomach is relatively weak, eat and swallow, and at night before going to bed, like to eat, drink milk, it is easy to lead to indigestion.

As for the elderly, their teeth are not good, their ability to chew food is reduced, and their activity level is too low. I have found that many elderly people will also like to eat braised meat very much, firstly, because it melts in the mouth, and secondly, because it can replenish yang qi. All these will lead to a decline in the peristaltic function of the gastrointestinal tract, abdominal pain and bloating, dry stools and other problems.

The above mentioned problems belong to functional dyspepsia, mainly due to improper diet, or insufficient exercise, as long as you can change the bad dietary habits and increase the amount of exercise appropriately, basically can be improved.

When we talk about bloating, of course, we do not exclude pathologic bloating.

First, epigastric distension, mostly seen in abdominal distension above the navel, pressure and pain there in the middle epigastric point, with hard nodules. It is mainly seen in dyspepsia, chronic gastritis, functional dyspepsia, cholecystitis, pyloric obstruction and so on.

Second, lower abdominal distension, mainly to the navel downward distension, most commonly seen in chronic colitis, irritable bowel syndrome, intestinal obstruction, gynecological complications, ureteral stones and so on.

Thirdly, total abdominal distension, most commonly seen in peritonitis, intestinal flatulence, functional dyspepsia, and intestinal obstruction.

If it is a long-term stomach bloating, after the examination did not find organic lesions, can be adjusted through diet and exercise, with massage therapy, acupuncture and moxibustion adjustment.

If it is an organic lesion, then it should be treated in a timely manner so as not to miss out on the condition.
