When sitting or lying down, I get dizzy as soon as I stand up, I can't see anything clearly, and I almost fell down several times. What is this? What should I do?

When you stand up, dizziness is mostly caused by transient hypotension. Because you stand up quickly, before the blood reaches your head, you will have cerebral ischemia and hypoxia, which is easy for young people, especially in summer and after defecation. There is no necessary connection with anemia. You should pay attention to strengthen nutrition and eat more foods rich in protein. Stand up slowly and stand for a while before you act. Matters needing attention in self-treatment of hypotension: (1) This disease belongs to the category of fatigue, so it should be treated as a whole, and the effect of drug treatment alone is not good. (2) Take an active part in physical exercise to improve physical fitness. The amount of exercise should be gradually increased, not rushed, but persevered. (3) When you get up, your eyes are dizzy or even dim. Before getting up, you should move your limbs a little, rub your face and rub your abdomen. When you get up, go to your seat for a while, then get out of bed and stand up slowly. Lift your feet slightly on the bed. (4) Life should be regular and diet should be nutritious. Usually, you can eat more foods that can warm the spleen and kidney and strengthen yang, such as venison, dog meat, mutton, rooster, wine, pepper, pepper, ginger, leek, longan, strong tea and coffee. (5) Drink more water and soup, and the daily salt is slightly more than ordinary people. Eat less melon, watermelon, gourd and red beans.
