Postural hypotension focuses on taking measures to prevent hypotension from occurring, such as strengthening physical exercise, eating a reasonable diet and paying attention to rest, drinking more water, moving slowly, and reducing the dosage of antihypertensive drugs. Postural hypotension is a sudden drop in blood pressure after changing body position. Postural hypotension can be diagnosed when the systolic blood pressure drops 20mmHg or (and) the diastolic blood pressure drops 10mmHg after standing compared to the lying position. Postural hypotension focuses on emphasizing the prevention of hypotension, and the following measures can be taken: 1. Strengthen physical exercise, enhance muscle strength, promote venous blood back to the heart through muscle compression, which can elevate blood pressure and reduce the symptoms of hypotension. 2. Reasonable diet and attention to rest. Patients with postural hypotension caused by malnutrition should pay attention to balanced nutrition and regular diet. Do not engage in physical activities immediately after eating. 3. Drink more water to increase blood volume, which can raise blood pressure. Especially those who sweat a lot after activities must pay attention to replenish light saline water in time to avoid hypotension caused by water and electrolyte disorder. 4. Move slowly, when you get up or get up, you must move slowly, you can do some preparatory activities for the limbs before getting up, which can help to promote the venous blood back to the heart. 5. If taking antihypertensive drugs caused by postural hypotension, it is recommended to reduce the dosage of the drug or replace it with other antihypertensive drugs, and follow the doctor’s instructions. If there is any discomfort, consult a doctor and follow the doctor’s instructions.
