Friend: Take more exercise in peacetime, strengthen physical exercise and improve physical fitness. No matter what you usually do, people with low blood pressure in the elderly should remember not to act too hard to avoid a sudden drop in blood pressure and fainting; Appropriately increase the amount of salt and drink plenty of water, because water can increase blood volume after entering the blood, thus raising blood pressure; Eating more dates is good. Eat more tofu, fish and shrimp; Eat more fruits and vegetables. Vegetables do not eat antihypertensive drugs such as celery, and fruits (such as hawthorn) are not eaten. As for medicine, my friend, you'd better consult a local doctor. I can't. Besides, mild blood pressure is as low as I said. I don't recommend using Shengmai drink. thank you
