Precautions for blood donation

Don't eat too much fatty food such as fatty meat, chicken, doughnuts, fried, etc. for dinner on the first day before blood donation and breakfast on the day of blood donation because if you eat too much fat, part of it will be absorbed by the blood and the blood donated may contain too much fat and become lipid blood. Do not drink alcohol or smoke, but do not donate blood on an empty stomach. You can eat some vegetarian food, such as bread, steamed buns and rice. 3. If you have a fever, cough, cold or diarrhea before donating blood, you should not donate blood, and women should not donate blood when they are menstruating. 4.

How long does it take to recover after blood donation?

The speed of recovery of various blood components after blood donation is inconsistent and is related to the amount of blood donated, the interval between blood donations, post-donation nutrition and individual differences. 1. The fastest recovery is for water and inorganic salts in the plasma, which recover 1 to 2 hours after blood donation. 2. Protein in the plasma, which is automatically synthesized by the liver after blood donation, can be recovered in about 2 days. 3. And the recovery of red blood cells mainly relies on bone marrow to make them, which takes about 3 weeks.

Do I need to take supplements after blood donation?

Many people worry that their body will not be able to keep up with the previous pace after blood donation and take a lot of tonic products. In fact, this is totally unnecessary; a healthy person who donates 200~400ml of blood will not have any effect on the body, let alone cause weakness, so there is no need to take tonic drugs. However, it is necessary to take appropriate supplements that are good for hematopoiesis. The main raw materials for hematopoiesis are protein, iron, vitamin B12 and folic acid, so they can be supplemented through diet, such as eggs rich in protein, iron-rich soybeans, celery, spinach, tofu, pork liver, etc. Folic acid and vitamin B12-rich foods are mainly found in fresh fruits and vegetables.

Will I gain weight after blood donation?

Gaining weight is due to uncontrolled diet and insufficient activity, and excess substances are converted into fat in the body. There is no direct relationship between blood donation and weight gain, so of course not. Most of the people who feel fat after blood donation are mainly due to the lack of exercise after taking a lot of nourishing food after blood donation.
