Through epidemiological surveys and experimental studies, the following factors are now considered to be closely related to high blood pressure, such as genetic factors, weight factors, nutritional factors, mental and psychological factors, etc. 1, genetic factors many clinical investigation data show that hypertension is polygenic inheritance, in the same family hypertension patients appear concentrated, not because they have a common lifestyle, mainly because of the presence of genetic factors. There are two types of genetic inheritance in patients with hereditary hypertension: (1) the primary gene for hypertension, which is bound to occur with age; (2) the secondary gene for hypertension, which does not develop in these individuals without the involvement of other factors that predispose to hypertension, but it is still difficult to detect these genetic factors in terms of morphology, biochemistry or function.

The results of our population studies, whether from univariate or multifactorial analysis, have demonstrated that high body mass index is an independent risk factor for elevated blood pressure. 3, nutritional factors, excessive salt, heavy alcohol consumption, excessive saturated fatty acids in the diet or unsaturated fatty acid to fatty acid ratio is too low, can make blood pressure rise. 4, smoking has been proved that smoking is one of the three major risk factors for coronary heart disease. According to the measurement: smoking two cigarettes 10 minutes after the secretion of adrenaline and norepinephrine increased, and the heart rate accelerated, systolic and diastolic blood pressure are elevated. 5, mental and psychological factors found in occupations with high tension, such as drivers, conductors, the prevalence of hypertension up to about 11.3%, followed by telephone operators, accountants, statisticians, the prevalence of 10.2%. This means that hypertension is likely to occur in people who are engaged in highly concentrated and stressful work and lack of physical activity. In conclusion, many factors are related to the development of hypertension, and hypertension may be the result of a combination of genetic, nutritional, weight and psychosocial factors.
