The proportion of young people suffering from hypertension is increasing, and there are two main reasons for this: First, for patients with primary hypertension, primary hypertension itself is caused by the interaction of genetic and environmental factors, when both parents of a young person are hypertensive, he himself has acquired this susceptibility to hypertension, it is more likely than others to be subject to the adverse stimuli of the external environment, resulting in Blood pressure increases. In addition, some young people have some very bad habits, such as smoking, alcohol abuse, high emotional and mental tension, irregular life, lack of sleep, lack of effective regular aerobic exercise, and obesity, which is now occurring in an increasing proportion of young people, all these adverse factors can cause a significant increase in blood pressure, especially young people tend to have a kind of They often do not monitor their blood pressure, which often causes it to be undetected even after a long time, which is very dangerous. Second, a small percentage of hypertension in young people is caused by secondary blood pressure diseases, such as some young people with renal stenosis, combined with renal insufficiency, or aortic constriction due to polyarteritis, or some tumors or abnormal growth of the adrenal glands caused by pheochromocytoma, primary aldosteronism, or cortisolism, these diseases themselves do not cause blood pressure to rise. These diseases do not cause an increase in blood pressure per se, but their symptoms can cause an increase in blood pressure, which is called secondary hypertension. Therefore, if a very young person has particularly severe hypertension, and the effect of medication is not good, it is also necessary to actively take appropriate tests to exclude the cause of secondary hypertension.
