Hypertension is divided into two types: primary hypertension and secondary hypertension, with primary hypertension accounting for more than 90%. The etiology of primary hypertension is not clear enough, and it is thought that it can be divided into two aspects: genetic factors and environmental factors. Hypertension is hereditary, and a history of hypertension in parents increases the likelihood of hypertension in their children, but genetics has a significantly lower impact on hypertension than lifestyle habits and environmental factors. Therefore, it is important to understand the risk factors that lead to hypertension and prevent it in advance. 70% to 80% of hypertension occurrences are related to unhealthy lifestyles. The following environmental factors predispose to hypertension: high salt diet, overweight or obesity, chronic excessive smoking and drinking, chronic mental stress and lack of exercise. In addition, age is also a cause of vulnerability to hypertension. Men > 55 years old and women after menopause are prone to hypertension. This is because blood vessels become more rigid with age, which increases the resistance of blood vessels around the body and raises blood pressure. If the high blood pressure is due to certain diseases (such as kidney disease? primary aldosteronism? pheochromocytoma, etc.), it is called secondary hypertension. Secondary hypertension is poorly treated with medication and must be treated for the cause, which can be effectively reduced or even restored to normal. Since 70% to 80% of hypertension is related to an unhealthy lifestyle, understanding the factors that influence hypertension and actively preventing it is an important way to prevent it.
