Does women's blood donation affect menstruation?

With the rapid development of modern medicine, it is now possible to treat a variety of complex diseases through blood transplantation. For example, excessive blood loss can be solved by blood transfusion, and most of the blood used for blood transfusion comes from donations from the public. Although voluntary blood donation is advocated, the prerequisite is that the blood donor himself must be in good health. So, does women's blood donation affect their menstruation?

From the perspective of blood physiology: the total amount of blood in the human body accounts for about 8% of body weight. The total amount of blood in an average adult is 4000-5000 ml, and 200 ml of blood donated at a time only accounts for 1/20-1/25 of the total blood volume. In clinical medical practice, blood transfusion is generally not recommended for blood loss below 600 ml. It can be seen that donating 200 ml of blood will never affect your health. However, women should take blood donation during menstruation very seriously.

1. It depends on each person’s different system . If the menstrual flow is light or abnormal (such as due to severe regional influence), it may result in no menstrual flow next month. People with weak bodies may experience aggravated dysmenorrhea. It is best to eat something that replenishes blood after donating blood, such as pork liver, donkey-hide gelatin and dates. You should also pay attention to your diet during the month of blood donation, and avoid eating anything that is too sour, too spicy or too cold. For those with strong constitution, there will not be much impact after donating blood, but you still need to be careful.

2. According to regulations, women cannot donate blood during their menstrual period or the three days before and after.

Women cannot donate blood during their menstrual period or the three days before and after this period because this period is when women are most vulnerable and unstable physically and mentally. Double blood loss is bad for women's health.

Donating blood must be avoided during this period.

3. Generally speaking, blood donation should not affect the normal time of menstruation. However, since women's menstrual period can be affected by psychological, emotional, and physical conditions, some individuals' menstrual period may be affected, usually delayed. The number of days of delay depends on each person's situation and the impact may vary.
