Can obesity cause high blood pressure? This question is asked by many people. It can be clearly told that obesity can definitely cause elevated blood pressure, which has been confirmed by many clinical studies. The key is how to diagnose obesity-related hypertension? Come on, Dr. Zhang will tell you.

There are 3 key points in determining if your hypertension is obesity related hypertension, the first is to determine if you are obese, the second is to determine if you have diagnosable hypertension, and the third is the need to rule out the possibility of secondary hypertension. As shown in the diagram below

1. How is obesity determined?

Strictly speaking, the measurement of fat distribution and content is the "gold standard" for the diagnosis of obesity, but it cannot be widely used because it is too costly and not easy to operate. Therefore, we still use the easiest amount of BMI and waist circumference to determine obesity. General obesity diagnosis cut point for BMI ≥ 28kg / m2 and/or male waist circumference ≥ 90cm, female waist ≥ 85cm.

2. How is hypertension determined?

The diagnostic criterion for hypertension associated with obesity is still recommended to be 140/90 mmHg, which is in line with the public perception of the diagnostic criteria for hypertension.

3. Rule out secondary hypertension

For some young hypertension, blood pressure elevation is more obvious, the effect of drug treatment is not good patients, to pay special attention to rule out the possibility of secondary hypertension. Because indeed some patients may also really obesity and hypertension are related to secondary diseases, such as Cushing's syndrome.

If you can meet the above 3 criteria, then your high blood pressure may be diagnosed as "obesity-related hypertension".

The world is always full of malice towards fat people, not only blood pressure, blood lipids, blood sugar will be affected from obesity, the reason is obvious.

Why does obesity affect blood pressure?

1. Heavy heart load

Obese people due to body size, more need for blood mobility, so the heart needs to be more ejection pressure to ensure blood circulation, due to prolonged cardiac ejection pressure, the blood vessel wall will withstand more than normal blood flow impact, over time, the blood vessels will produce spasms, resulting in hardening, thinning, so that the body's self-protection system will allow the heart to produce a greater ejection pressure to ensure that the circulation of blood. .

2. Too much fat

Excessive fat and high blood pressure are directly related to the body fat content is too high, too many impurities in the blood, easily caused by the narrowing of blood vessels, thereby increasing the burden on the heart blood pressure values will rise significantly.

3. No movement

The body does not exercise consumption, the blood pressure value has an indirect effect, blood impurities caused by blood vessel blockage impurity excretion channels only two places, defecation and sweat, and these can be linked to the body metabolism, and overweight people, certainly do not love sports, and the body metabolism cycle itself is slower than normal, it will lead to more impurities in the blood, so that the blood pressure rises.

In conclusion, obesity is a major contributor to elevated blood pressure, and fat people who lose 10% of their own body weight can notice a significant drop in their blood pressure.

With the acceleration of urbanization and aging, chronic diseases have become a major public health problem affecting the health of the population, and hypertension is one of the chronic diseases with a high prevalence rate. At the same time, high blood pressure risk factors such as obesity, smoking, excessive alcohol consumption, high salt and high fat food intake are prevalent in the population, becoming a potential threat to cardiovascular and cerebrovascular diseases such as hypertension, myocardial infarction and stroke. So how does obesity affect blood pressure?

The important feature of obesity-related hypertension is that, in general, patients with elevated blood pressure is closely related to obesity, when the control of body weight will be able to effectively reduce blood pressure. The mechanism of its occurrence is still inconclusive, some researchers believe that due to the large increase in adipose tissue in obese people, the total metabolism and the body's oxygen consumption increases, the relative increase in blood circulation, in the case of the normal heart rate, the heart to increase the amount of beat a lot of long term overburden, the left heart hypertrophy, elevated blood pressure.

For patients with obesity-related hypertension, simple blood pressure control to meet the standard is not effective in controlling the risk, the need to simultaneously control obesity, improve obesity-related metabolic disorders, and therefore the need for comprehensive intervention, individualized treatment.

1. Lifestyle intervention The most effective measures for weight reduction are to control energy intake and increase physical activity. In terms of diet, we should follow the principle of balanced diet, control the intake of high-calorie foods (high-fat foods, sugary beverages and alcohol, etc.), and appropriately control the amount of staple foods. In terms of exercise, regular, moderate-intensity aerobic exercise is an effective way to control body mass. For patients with severe obesity whose weight loss results from non-pharmacological measures are unsatisfactory, weight-loss medications can be used to control body mass under the guidance of a doctor.

2. Antihypertensive drug therapy Expert consensus recommends that angiotensin II receptor blocker (ARB) or angiotensin-converting enzyme inhibitor (ACEI) type of drug therapy is preferred, such as captopril and chlorosartan as the first-line therapeutic drugs for obese patients. Calcium channel blockers (e.g., nifedipine, amlodipine, etc.) are commonly used antihypertensive drugs and can be used as combination therapy. The selection of antihypertensive drugs suitable for patients should be made according to their specific conditions and tolerance and personal wishes or long-term affordability.

In the student population, "little pudgy" has become a common population, a survey shows that the current obesity rate of elementary school students in about 8%, early childhood obesity adult, the risk of metabolic syndrome than the weight of normal children to be much higher.

The main reason for obesity and diet is irrelevant, now the economic conditions are good, no matter how the economic conditions want to eat a few mouthfuls of meat is the easiest to meet the desire. People no longer simply want to eat a mouthful of meat, began to pursue a variety of fresh eating methods, meat baked, shabu-shabu, fried, and even eaten raw.

A meal of meat to the stomach, meat in the fat is also stored in the body, and fat is obesity, hypertension, high blood pressure, high blood cholesterol, pancreatitis, intestinal cancer and many other chronic diseases of the causative agent.

Life in addition to the meat in the fat, some other fruits, snacks, there is also the presence of fats. Today's explosion of nutrition classroom dietitians, talk to you about: grease is obesity, cardiovascular disease triggers, advise you to eat less than 1 type of vegetables, 1 kind of fruit, 1 kind of home meat.

1, this food hides fat: fried food

In Chinese cooking techniques, oil is a very special existence, as long as the food is fried in oil instantly becomes delicious. Deep fried potatoes, deep fried eggs, deep fried chicken thighs, oil can deep fry a lot of foods.

Foods that can be fried, whether they are otherwise healthy vegetables or staple foods, have the presence of fats and oils attached to them. Some surveys have shown that people who love fried foods have 56% more risk of heart disease compared to those who eat a healthy diet.

Deep-frying will transform low-fat grains, potatoes, vegetables, etc. into high-fat, high-calorie foods with a fat content of more than 20% or even more than 30%. In addition, oil at high temperatures will also produce a variety of carcinogenic substances, also not good for the body.

2, this food hides fat: avocado

Fruits are rich in vitamins and minerals, dietary fiber, especially during the weight loss period of the girls every day with a lot of fruit to replace the main food. But the choice of fruit is also very critical, like avocado, durian and other fruits actually contain the same fat.

Avocado actually has a nickname called "forest cream", an ordinary size avocado, there are about 240 kcal calories, which is close to the calories of a bowl of rice 232 kcal. If you eat an avocado every day after dinner to do after dinner fruit, equivalent to an additional bowl of rice, such fruit really need to eat some less.

3, this food hides fat: pork

Pork is the largest per capita consumption of meat, pork contains calcium, iron, vitamin B12 and other nutrients, occasionally eat some of the gluttony can also be supplemented with nutrients. But the biggest problem with pork is that the fat content is too high compared to beef, lamb and fish.

Like everyone's favorite pork, the fat content can reach up to about 30%, in stewing or frying pork usually have to add additional oil, and further increase the content of fat. And a long time of stewing or braising will also make the B vitamins in pork disappear.

In fact, in addition to the above 3 types of high-fat food, like sesame seeds, nuts, potato chips and other foods in the fried content of the same is not low, should also pay attention to eat less. So what is a healthy way for obese people to eat?

In terms of cooking methods, try to choose steaming and chilling methods, and avoid high-temperature frying and barbecuing food. In terms of staple food, consciously increase the proportion of coarse grains, and chew slowly and reduce the speed of eating. In terms of food types, pay attention to food variety and include at least two kinds of vegetables in every meal, especially dark leafy greens.

Of course it will.

Obesity is an abnormal or excessive accumulation of adipose tissue. Indicators of abdominal obesity (e.g., waist circumference, etc.) can better evaluate the elasticity of blood vessels and predict cardiovascular risk than central obesity indicators (body mass index). Normal waist circumference in adults is 90/85cm (male/female).

Obese people are often accompanied by hypertension, and obesity is an independent and primary risk factor for hypertension. Important advances have been made in the mechanisms of obesity-induced hypertension. It is now believed that sodium retention is the key cause of obesity-induced hypertension. In addition, endothelial dysfunction, destruction of renal structure, activation of the renin-angiotensin-aldosterone system and activation of the sympathetic nervous system also play important roles.

In the past 20 years, the prevalence of obesity and hypertension have both shown a significant upward trend globally, and obesity can not only increase the difficulty of blood pressure control in hypertensive patients, but also promote the aggregation of multiple cardiovascular metabolic risk factors and aggravate cardiovascular and cerebrovascular damage.

Therefore, although obesity is not an inevitable factor in triggering hypertension, obesity and hypertension are like a pair of twin sisters, obesity has become a risk factor for inducing hypertension, and obese people are more likely to suffer from hypertension.

According to a high blood pressure survey tracking report shows that 60 percent of patients with high blood pressure, found that more than 20 percent of the body weight is obese. Overweight and obese people suffer from high blood pressure risk is two to three times that of normal weight people.

Therefore, if obesity is found to coexist with hypertension, weight loss should be undertaken immediately.

How can you tell if you are obese?

3. Eat small meals, eat scientifically and avoid overeating.
