Suddenly stood up and my eyes turned black

Many times, when people suddenly stand up or have been sitting for a long time, they feel that their eyes go dark and they see stars when they suddenly move. This symptom makes people feel uneasy and they don't know what the problem is. In fact, this is a very normal physiological reaction. It is a pituitary manifestation caused by a sudden change in the individual's body position.

Mitigation methods

Prognosis of black eyes

Prevent the causes of the disease, such as anemia: eat more iron-rich foods, such as lean meat, pork liver, egg yolks, kelp, hair algae, seaweed, fungus, shiitake mushrooms, beans, etc. Pay attention to a reasonable diet, such as eating some fruit after a meal. Fruits contain rich vitamin C and fruit acids, which can promote the absorption of iron.

Drinking strong tea after a meal will cause the iron to combine with the tannic acid in the tea to form a precipitate, which will affect the absorption of iron. In addition, cooking food in an iron pan is very helpful in preventing anemia. Folic acid and vitamin B12 are also essential substances for hematopoiesis. Fresh green vegetables, fruits, melons, beans and meat are rich in folic acid. Meat and internal organs such as liver, kidney and heart are rich in vitamin B12. However, after high-temperature cooking, more than 50% of the folic acid and 10-30% of the vitamin B12 can be destroyed.

Therefore, in life we ​​should pay attention to dietary diversity, pay attention to cooking techniques, and try to avoid over-steaming and cooking food.

We must protect the blood-forming factory. Many chemical and physical factors can damage the bone marrow. Chemical factors such as benzene, organic arsenic, anti-tumor drugs, certain antibiotics (such as chloramphenicol, streptomycin), sulfonamides, anti-epileptic drugs, anti-rheumatic drugs (such as butasol, indomethacin), etc.; physical factors such as X-rays, B12, gamma rays, neutrons, etc. can all damage the bone marrow and are the enemy of hematopoiesis. Therefore, protective measures should be strictly implemented and operating procedures should be followed. In particular, drugs that are harmful to hematopoietic function should not be abused, and unnecessary X-ray exposure should be avoided.

Blood loss is also an important cause of anemia. Therefore, various hemorrhagic diseases, such as hookworm disease, hemorrhoids, functional uterine bleeding, etc., should be actively treated.
