Asthma is a common respiratory disease that is more common in adults and affects about 30 million people nationwide. An asthma attack is characterized by shortness of breath, accompanied by coughing, anxiety, and a distinct rumbling sound can be heard. There are many causes of asthma, which are mainly categorized into genetic and non-genetic factors.

I. Genetic factors

According to studies, the heritability of asthma is 60% if both parents are asthmatics. Two genes associated with asthma have been identified through family chain gene studies, ADAM33 and RhF11.

II. Non-genetic factors

1, exercise: exercise-induced bronchospasm and exercise-induced wheezing is very common in asthma patients

See, it is estimated that 40% to 90% of asthmatics have exercise-induced symptoms. This is because after exercise, lung function is significantly weakened and is a high risk factor for asthma attacks.

2, aspirin and other analgesics: some patients will take aspirin after an asthma attack, this

The type is called aspirin-induced asthma. In addition to aspirin, ibuprofen, naproxen, and diclofenac can likewise cause asthma attacks; acetaminophen has a lower probability of inducing an asthma attack, less than 10 percent. The prevalence of aspirin asthma is 21% in adults and 5% in children.

3、Specific allergens: Most patients will have an asthma attack after exposure to certain specific allergens.

This type is called exogenous asthma. Some of the familiar ones in this category are: foods such as soy and seafood, cold air, dust, and animal hair. Asthma also has an occupational component, for example, people working in the poultry industry, seafood processing industry, and printing industry have a higher prevalence of the disease than the general population. Common occupational causes of asthma are shown in the chart below:

Asthma belongs to the reversible pathology, in the normal state, asthma patients are no different from normal people. In order to maintain this normal state, in our daily life, we should pay attention to the following points:

1. regular use of asthma medication to avoid acute asthma attacks, especially regular inhalation of medications containing glucocorticosteroids

Hormonal and bronchodilator maintenance medications, e.g., drugs such as salmeterol ticarcoson.

2. For infants and young children, breastfeeding should be practiced to reduce the incidence of wheezing. For pregnant women, pregnancy

Foods high in vitamin D and vitamin E should be consumed, which can reduce the incidence of wheezing in children.

3. Avoid contact with allergens, especially in infants and young children. Allergens can be removed from the body by passing

Allergen testing to determine this. Avoid analgesic medications such as aspirin, and although acetaminophen is less likely to cause asthma attacks, it is for pregnant women who should avoid acetaminophen, as it can lead to an increase in asthma in offspring.

4. Refrain from smoking and avoid exposure to second-hand smoke as much as possible, especially pregnant women should be prohibited from smoking. For asthma

Patients, should be in the regular use of asthma medication, asthma get smooth control of the situation, moderate amount of soothing exercise, should not be rushed to a large number of exercise.

Asthma is categorized into two types: cardiogenic asthma and bronchial asthma. Most of the common clinical asthma is bronchial asthma, which is a disease of bronchial spasm, narrowing, and increased mucus secretion caused by chronic airway inflammation involving a variety of cellular and cellular components, and in addition, genetic factors are also the main causes of asthma. Bronchial asthma is mainly characterized by recurrent episodes of wheezing, dyspnea, chest tightness, and coughing symptoms, which are especially noticeable at night and early in the morning.

Bronchial asthma is categorized into four grades according to the severity of the respiratory restriction: intermittent attacks, mild persistent, moderate persistent, and severe persistent. An attack is often preceded by aura symptoms such as sneezing, runny nose, cough, and chest tightness. Its attacks are often caused secondary to a variety of triggers such as the following.

1. Inhalers: pollen, fungi, animal dander, penicillin, etc.

2. Infectious factors: the formation and attack of asthma is related to repeated respiratory infections, some parasites such as roundworms, hookworms can also cause asthma attacks.

3. Food: The most common foods that cause asthma are fish, shrimp and crab, eggs and milk.

4. Climate change: Asthma attacks are likely to occur in the cold season or during the fall and winter when the climate changes.

5. Mental factors: the patient's emotional excitement, nervousness, anger, etc. can prompt an asthma attack. 6. Exercise and exertion: it is easy to trigger an asthma attack in adolescents.

7. Drugs: e.g., cardiac glycosides, aspirin-type drugs.

8. Menstruation, pregnancy factors: some female patients have asthma exacerbation 3-4 days before menstruation, sometimes pregnancy can also trigger asthma and aggravate asthma symptoms, but there is no certain regularity.

For people with a history of asthma or family history should promptly cure the primary diseases that are prone to asthma attacks, and try not to come into contact with the above triggering factors in their normal life, which can avoid the occurrence and recurrence of asthma attacks.

A combination of genetic and environmental factors

There are two errors in this line of questioning, but everyone who reads it will have their own answer based on their own perceptions. I'm certainly no exception. Check out mine.

Asthma, is a term that combines the words croup and wheeze. Croup and wheezing are both episodic states in themselves, as well as episodic symptoms. What is a symptom? It is: the state of the body not being normal. So asthma is a symptom and a result. Since it is a result, it should have a cause. What is the cause of asthma? It makes sense to ask that. Or ask: What causes asthma?

No."asthma"Nouns like that can't just be added after symptoms."病"The word, are now Chinese people, influenced by Western medicine, move like in the disease or symptoms (signs) after the addition of the word disease. Carefully study the English: disease (It's made up of ease+dis.) What does it mean? It is: comfortable + not, i.e.: uncomfortable. Uncomfortable belongs to the Chinese category of syndrome, but has a smaller connotation than syndrome. Which Chinese character would be more appropriate? There are only three Chinese characters to choose from: 症,疾, and 病. The original translators chose "病". What is the initial meaning of disease? The initial meaning was "疾加也", which means heavier than "疾". Coronary heart disease (CHD) translates to coronary heart disease (CHD), and people almost always think that CHD is a kind of disease, with the same cause, the same symptoms, the same treatment, the same effect/result, but it's not the same at all. /results are the same, when in fact they are not the same at all.

English, asthma, corresponds to Chinese: asthma.And they didn't just add on the backDISEASE, so, can't say asthma.

Since it's not asthma, you can't say: the asthma causing "etiology". As asthma is a disorder, it should be said that what causes asthma: the cause of the disorder. See the chart below.

What is the symptomatic cause of asthma, as can be seen in the chart above? It should be said that it is certainly not a "因", but rather a plurality of possible causes, a cause understood as "rationale"And? Or is it understood as "considerations"And?

What is the cause? It is: the condition and factor that started it all. So it makes more sense to understand it as a cause. But once it is understood as a cause, it involves whether it is a single cause or multiple causes? Multiple causes are: primary, secondary, or auxiliary? Whether it's primary or secondary or something else, is it an internal cause or an external cause? In many cases it is causative? Cause in the term causative would have to be understood as "factor", not as cause. This is where I often find language and words awkward.

Nowadays, the mainstream thinking of Western medicine is that because of the bronchospasm, when the bronchospasm is relieved and there are no more asthma symptoms, it is considered to be well. After years of clinical research and practice, I believe that this viewpoint is not correct, at least not completely correct. In fact, bronchospasm is also the result, and is not the first factor that causes asthma. So what exactly is the very first factor that causes bronchospasm, or asthma?

People are used to thinking about things this way: if this person's asthma is caused by this factor, that person's asthma should be caused by the same factor, or even, everyone's asthma is caused by the same factor. In fact, it is not at all.

Upon closer examination one realizes that no two things in the world are exactly the same. The same is true for illnesses. So to summarize: all symptoms are "apparently right but actually wrong; specious"The. For more details, go to the article in my headline:Cough of the plausible deniability ---- This cough is like another cough, this cough is not another cough also. All symptoms should be considered in this way to be effective. So there is no one-size-fits-all cure or medication for asthma. And all treatments only work to a certain extent. It's impossible to be able to: cure all asthma in all patients.

Based on the above theories, the causes of asthma in each individual can have similarities to the causes in others, not identical. The only way to cure it completely is to remove the cause. All medications used to relieve bronchospasm, such as theophyllines, beta 2 agonists, leukotriene receptor antagonists, antihistamines, glucocorticosteroids, etc., are symptomatic treatments, and none of them are removing the cause.

Someone said, "Allergic asthma, find the allergens, don't touch them and you won't develop asthma"It is also incorrect to say that, in my opinion, the so-called allergens that are justincentivesIt is only the factor, not the cause. Removing the trigger only achieves a temporary absence of asthma attacks, it only removes the factor, not the cause, so that asthma attacks will still occur at a later time when the time is right. All of the asthma medicines are just removing thenotable diseaseturnundetected illnessOnly, the triggers (allergens) are the ones that turn a hidden condition into a visible one quickly. See the diagram below

So, the causes of asthma are similar to the causes of any other symptom, which are internal and external. It is a case-by-case analysis as to which one is the cause for a particular person.

For example: wheezing bronchitis, which is also asthma, is just a different term, but asthma is actually a concomitant symptom of bronchitis. All asthma is a concomitant symptom. Patient A's bronchitis is caused by Staphylococcus aureus, B's is caused by Pseudomonas aeruginosa, C's may be caused by Rickettsiae, D's may be caused by inhalation of chemical poisons, and so on, and even though the results are the same, the causes are very different, and the treatments of course cannot be the same. This also explains why so many ancient Chinese medicine treatment of asthma prescription is not effective, or ineffective reason. It is because the later people did not use the right patients who should have used them. It is certainly not the experience of the ancients that is wrong. But it is also possible that the words used by the ancients in their records were wrong.

Hopefully, people are getting the point.

Asthma is a disease of the respiratory system, human breathing through the mouth, nose, throat, trachea and lungs to realize this cycle, in which the trachea and bronchial tubes are surrounded by smooth muscle, can be contracted and diastolic, and then control the rhythm of breathing. In asthma, the bronchial tubes become unstretched after exposure to allergens, resulting in wheezing, chest tightness and other respiratory difficulties.

Let's discuss the causes of asthma. The first part lies in heredity, which runs in families, and the closer the blood relationship, the more likely to develop the disease. However, heredity is only a basis for the onset of the disease, and in reality the onset of asthma often occurs after exposure to allergens, such as polluted air, allergens such as pollen, dust mites and the like, and the consumption of allergic foods or medications, and so on.

For asthma patients how to reduce asthma attacks? First of all, we should avoid contact with allergens, and secondly, parents should not overly pursue spotless when bringing up children, the human body and the environment also have a process of mutual adaptation, especially clean people are prone to asthma when they grow up, and in addition to add more exercise, enhance physical fitness, improve immunity. Asthma attacks should be timely application of bronchodilator drugs and anti-inflammatory drugs.

I hope that my answer will help you! Give me a like if you like it!

The causes of asthma are categorized into cardiac and pulmonary asthma. Pulmonary causes are most common in allergic asthma. Characterized by an attack of asthma immediately after exposure to an allergen, the symptoms are acute and severe, and after detaching from the allergen and correct anti-allergy treatment, the asthma symptoms soon subside as normal!

Patients with cardiogenic asthma have a history of more severe cardiac disease, such as severe hypertension, etc., leading to asthma from acute left heart failure. This is a clinically critical condition and requires emergency care!

I'm Chinese medicine practitioner Zhong Zi Jing.

Asthma is an allergic disease characterized by expiratory dyspnea with rales caused by congenital genetics, allergic qualities, climatic and environmental changes, or other sensitizing factors, and the disease is often recurrent. More than half of them develop before the age of 12.''

1, in fact, asthma is not without reason will have an attack, generally also have allergens produced to cause patients to have an attack. Generally the patient in the daytime after exposure to allergens, after six to eight hours after the asthma will begin to attack, so many asthma patients are in the night attack.

2, If the sleeping position is not good, it can also cause asthma attack. Because the lungs are particularly weak at night. If you sleep on your back, the breathing resistance of the airways will be significantly increased, which will be prone to asthma attacks.

3, the family has asthma patients, the room air must not be too dry, especially at night. Generally the air at night will be drier than during the day, so the family with asthma patients can drink a glass of water before going to bed to prevent asthma attacks at night.

I think asthma, the cause is very complex. Any etiology and cause it is very complex, the most important is the genetic inheritance of the gene, Chinese medicine is believed to be so, asthma is and this lungs and kidneys have a direct cause and relationship. Weakness of the spleen qi and loss of nourishment in the latter part of the body. The deficiency of lung qi and kidney qi leads to the weakness of the lungs and coughing and asthma. Chinese medicine believes that the lungs, spleen and kidneys are interconnected. The five organs and six bowels are mutually exclusive. ......

It is considered to be mostly due to allergies. Allergens may be biological, plant, animal, or barring that, chemical factors, etc.
