Low blood pressure can be caused by the following factors: 1. For patients who take antihypertensive drugs for a long time, if they have low blood pressure, it may be due to excessive use of drugs, or because the temperature rises and the blood vessels dilate, which makes the blood pressure drop. If the blood pressure is reduced due to drug overdose, it is necessary to adjust the use of drugs in time. 2. In addition, a large amount of fluid loss, such as massive bleeding, nausea, vomiting, diarrhea, etc., will lead to a significant reduction in blood pressure. 3. Patients with long-term poor food intake may also have obvious hypotension.
