A diastolic blood pressure below 50 mmHg should be considered hypotension. If the hypotension is caused by physiologic factors, no treatment is needed and the causative factors can be removed. If the hypotension is caused by pathologic factors, a specific treatment plan should be formulated according to the specific cause of the disease. 1. Hypotension caused by physiological factors: it can be seen in patients who are short and thin, and the low blood pressure of this kind of people does not affect their health and does not need to be treated. 2. Low blood pressure caused by pathologic factors: low blood pressure caused by certain diseases, such as severe aortic valve stenosis, can be carried out in regular hospitals for heart valve replacement surgery. Another example is low blood pressure caused by hypothyroidism, which can be treated with drugs such as levothyroxine sodium under the advice of a doctor. There are many other causes of low blood pressure. If you have any discomfort, please go to a regular medical institution for consultation and treatment.
