Will donating blood reduce menstruation?

As we all know, regular blood donation is actually very encouraging. However, some female friends are worried that donating blood will affect their physical health. If people donate blood blindly, it will indeed be harmful to the body, but if people donate blood normally, then there will basically be no problem. But some women still ask: Will donating blood reduce menstruation?

Donating blood will not reduce your menstrual period. Menstruation is the process by which the endometrium is shed and mixed blood is discharged from the vagina due to the withdrawal of hormone levels. The amount of menstrual flow is related to the blood supply to the uterus, the thickness of the endometrium, and hormone secretion. You need to undergo an examination before donating blood. If you have anemia or other indicators do not meet the requirements, you cannot donate blood. Moreover, blood can be regenerated and will not cause changes in menstrual volume. You can strengthen nutrition and supplement protein, iron and vitamin C appropriately.

The establishment of a normal menstrual cycle depends on the neuroendocrine regulation of the hypothalamus-pituitary-ovarian axis and the cyclical response of the target organ, the uterus, to sex hormones.

Therefore, if any of these links fails, amenorrhea may occur. There are generally five major causes, namely uterine amenorrhea, ovarian amenorrhea, hypothalamic amenorrhea and other causes (such as mental factors, environmental factors, etc.) and amenorrhea caused by endocrine dysfunction.

1. Uterine amenorrhea: amenorrhea caused by uterine hypoplasia. The common symptoms are no menstruation or late menarche after the age of 18, scanty menstruation, and gradually amenorrhea. Gynecological examination showed a small or immature uterus;

2. Ovarian amenorrhea: amenorrhea caused by ovarian dysfunction. It is often accompanied by vaginal dryness, dyspareunia or infertility. Amenorrhea caused by premature ovarian failure is characterized by amenorrhea before the age of 40, accompanied by menopausal symptoms such as facial hot flashes, hot sweats, irritability, etc. Amenorrhea caused by polycystic ovary syndrome may be accompanied by obesity, hirsutism and infertility.

3. Pituitary amenorrhea: Amenorrhea caused by pituitary tumors may be accompanied by headaches, blurred vision, or lactation; amenorrhea caused by anterior pituitary necrosis occurs during postpartum hemorrhage and is manifested by decreased libido, genital atrophy, fatigue, fear of cold, and hair loss.

4. Hypothalamic amenorrhea: It often occurs after mental trauma, excessive mental stress, severe malnutrition and oral contraceptives. Amenorrhea occurs suddenly.
