How is hypertension caused?

1. Heritage

Hypertension is a disease with genetic factors. According to clinical investigation and analysis, nearly 33% of patients with hypertension are caused by genetic reasons. If you have both family history and bad habits, it is easier to induce hypertension.

2. Age

The incidence rate tends to increase with age, and the incidence rate is high in people over 40 years old. Usually, the elderly are at high risk of hypertension, which is a common clinical phenomenon. Generally speaking, the older you get, the greater the risk of hypertension. Many middle-aged and elderly people are very prone to hypertension, which shows that this is a factor closely related to the incidence of hypertension.

3. Gender

Since puberty, men's blood pressure tends to a higher average level. This difference is most obvious among young people and middle-aged people. After middle age, the change of female hypertension incidence rate is partly due to the higher premature mortality rate of middle-aged hypertensive men.

4. Weight

The incidence of obesity is high, and most hypertensive patients have more fat. Obesity will increase the fat content, which will cause a great burden on the body itself. The increase of weight will cause a greater load on the heart, and the increase of blood volume will also lead to an increase in vascular resistance. Therefore, obesity plays an important role in the pathogenesis of hypertension.

5. salt

People who eat more salt have a high incidence of hypertension, with the incidence of 20g/ day being 30%. Therefore, excessive salt intake is also one of the factors leading to hypertension. In addition, low intake of potassium and calcium, and insufficient intake of high-quality protein are also considered as one of the factors that can increase blood pressure.

6. Mental stimulation

This is one of the important reasons why the elderly in rural areas suffer from less hypertension than those in cities. Noise pollution is rare in rural areas, and farmers live a simple and free life. Without the pressure of making a living in a big city, they are more relaxed mentally and have less chance of suffering from high blood pressure. Moreover, people who engage in mental work are more likely to suffer from high blood pressure than those who engage in manual work. Mental stress, increased catecholamine secretion in the body, will cause vasoconstriction, aggravate the heart load, and cause hypertension. So learn to relax yourself and choose a quieter environment in the house.

7. Smoking

Smoking is the inducing factor of many diseases, and hypertension is one of them. Long-term smoking will make arterioles contract continuously, form arterioles sclerosis, and cause blood pressure to rise. According to the measurement, after smoking two cigarettes 10 minutes, due to the increased secretion of adrenaline and norepinephrine, the heartbeat is accelerated, and both systolic and diastolic blood pressure are increased. Smokers are prone to malignant hypertension, and nicotine in tobacco leaves affects the efficacy of antihypertensive drugs, which is not conducive to the treatment of hypertension.

8. Drink

There is a dose-response relationship between excessive drinking and blood pressure. With the increase of alcohol consumption, systolic blood pressure and diastolic blood pressure gradually increase, and the incidence of hypertension increases in the long run. Excessive drinking can also lead to the risk of stroke. The guidelines for prevention and treatment of hypertension in China suggest that men should drink no more than 30mg (about 1 liquor) and women should not drink more than 20mg every day.

9. Birth control pills

The incidence and degree of hypertension in women who take contraceptives are related to the length of time they take contraceptives. People over 35 are prone to high blood pressure. Hypertension caused by oral contraceptives is generally mild and reversible, and blood pressure often returns to normal after 3 ~ 6 months of withdrawal.
