Hypertension has a distinct genetic predisposition. Epidemiological studies suggest that the incidence of hypertension has a distinct familial clustering. It is estimated that at least 20%-40% of the blood pressure variations in the population are determined by genetic factors. So, if parents have high blood pressure, children are significantly more likely to be ill than people whose parents have no high blood pressure. Heredity is a very important factor, but it is not an absolute factor.

If parents have high blood pressure or one of their parents is hypertension, what is the probability of their children suffering from hypertension?
If both parents have no hypertension, their children are much less likely to suffer from hypertension than if both parents have hypertension. According to the survey, children of both parents without hypertension have a 3% chance of developing hypertension; and children of both parents with hypertension have a 28% chance of developing hypertension; if both parents have hypertension, their children's prevalence will increase to 46%. 65% of the adult siblings of hypertension patients suffer from hypertension. In twins, the prevalence of hypertension in monozygotic twins is significantly higher than that in twins, which further illustrates the important role of inheritance in hypertension. Factors associated with hypertension include hyperlipidemia, obesity, diabetes, and high salt diet. Therefore, to put it more popularly, the main factors that lead to hypertension include gene plus environment, that is, under the effect of Polygene inheritance, plus the same family living environment, eating habits, personality hobbies and so on, and so on, the tendency of frequent family disease. Of course, this does not mean that parents with high blood pressure, children will have high blood pressure, hypertension can be reduced by controlling other causes of high blood pressure, such as smoking, alcohol, excessive fatigue, emotional instability, etc.
