Specifically, what is the cause of hypertension?

1. Hereditary hypertension is common in middle-aged and elderly people, and more than 40% have a history of hypertension. Parents do not have high blood pressure, and the probability of children suffering from high blood pressure is only 3%. More than 60% of the elderly suffer from obvious cardiovascular and cerebrovascular diseases, among which the related cardiovascular diseases caused by hypertension account for the vast majority;

2. Overweight and obesity are important causes of hypertension. Obesity can not only cause hypertension, but also easily lead to coronary heart disease, cholecystitis, arthritis and other systemic diseases. Most obese people are sleepy and have a good appetite, which is easy to form a vicious circle;

People who are emotionally unstable are also prone to high blood pressure. People who are nervous, grumpy, always hesitant, hard to make up their minds after repeated thinking, too anxious, engaged in mental work and highly nervous are prone to hypertension. The drug treatment effect of this kind of hypertension population is often poor;

Smoking and drinking are also the main causes of hypertension. Swallowing is the most important risk factor for hypertension and coronary heart disease. Long-term heavy smoking will increase heart rate and blood pressure. The incidence of cardiovascular accidents and myocardial infarction in smokers with mental stress and type A personality is 2-4 times higher than that in normal people. Long-term alcoholics often have hypertension, obesity, hyperlipidemia and hyperglycemia;

5. People with too much salt are more likely to suffer from high blood pressure. Northerners are prone to high blood pressure, and one of the reasons is related to salty diet. The main component of salt is sodium chloride. Eating too much salt will lead to too much sodium in the body, increased vascular resistance, increased cardiovascular burden and increased blood pressure.

Prevention methods of hypertension

1. Control heat energy and weight: Obesity is one of the risk factors of hypertension, and the main reason for obesity is excessive calorie intake. Therefore, reducing calorie intake and increasing exercise to control weight is one of the most important methods;

2. Limit salt. It is well known that sodium salt can cause hypertension, so it is necessary to limit salt. Anyone with mild hypertension or family history of hypertension should control the daily salt intake below 5g, especially those with hypertension or heart failure. The daily salt intake should be1~ 2g.

3. Improve diet structure, reduce animal fat with high saturated fatty acid content, and increase plant food rich in unsaturated fatty acid.
