There is no direct relationship between thin people and high blood pressure. Heredity, diet, and mental factors can also lead to high blood pressure. Weight gain is an important risk factor for elevated blood pressure, obesity and hypertension have a close relationship, abdominal obesity is more likely to occur hypertension, but thin people do not necessarily have hypertension. There are more common triggering factors for hypertension, and the most common ones are genetic, dietary, mental and other influences. 1. Heredity: hypertension has obvious family aggregation. If both parents have high blood pressure, the probability of their children developing the disease will be significantly higher. 2. Diet: Studies have shown that blood pressure level and prevalence of hypertension are closely related to the average intake of sodium, so the probability of hypertension is higher in people with high salt diet. 3. Mental: The prevalence of hypertension is higher in mental workers than in manual workers, and those who are engaged in occupations with high levels of mental stress are more likely to develop high blood pressure. It is recommended that people with abnormal blood pressure should go to the hospital in time and be treated by a professional doctor.
