The contraindications for women to donate blood are menstruation, pregnancy and lactation.
1. You can’t donate blood during menstruation, before menstruation, and 3 to 7 days after menstruation because a lot of red blood cells have been lost during menstruation, and if you donate blood, it is easy to cause fatigue, pallor, and panic attacks after activities and other discomforts.
2. Anemia is easy to occur during pregnancy, and donating blood will increase the probability of anemia, which will adversely affect the pregnant woman and the fetus.
3. Women who are breastfeeding are physically weak, and if they donate blood, it may cause their body resistance to drop.
Women with high blood pressure need to have their blood pressure controlled below 130/80mmHg before they can donate blood. If there are diseases such as syphilis, AIDS, viral hepatitis, etc., they cannot donate blood.
Before blood donation, you should avoid exertion and staying up late, and you need to eat breakfast to avoid hypoglycemic reaction.
