Why do women have their periods?

Mature women have their periods every month, which is what we usually call the menstrual period. Generally, a woman's menstrual period is about three to seven days, during which time a certain amount of blood will be discharged from the vagina. Women have their periods every month, which is closely related to the cyclical changes in the endometrium. The endometrium sheds and repairs, and this is a cycle. This is an important reason why women have their periods.

Why do women have their periods?

This is related to the cyclical changes in the endometrium. The endometrium is divided into two layers. The surface layer is called the functional layer. The changes in the menstrual cycle mainly occur in this layer, which undergoes shedding and repair every menstrual cycle. The layer close to the muscle is called the basal layer. After the functional layer falls off during the menstrual cycle, a new functional layer is produced from this layer. The endometrium undergoes periodic changes as the ovaries release ovulation.

4 benefits of menstruation for women

1. Promote hematopoietic function.

Menstruation causes women to lose a large amount of blood, so that their hematopoietic function can be exercised regularly. It enables women to withstand the blow of accidental blood loss better than men and can produce new blood more quickly to make up for the lost blood. Practice has shown that if men and women with the same weight and health status lose the same proportion of blood due to an accident, the man will die, while the woman has the possibility of being successfully rescued and eventually recover.

2. It can directly reflect whether a woman is pregnant.

If a woman's menstruation is delayed for more than ten days, the first thing to consider is whether she is pregnant. After confirming pregnancy, those who are not planning to have a baby should take remedial measures as soon as possible; those who want to have a baby should pay more attention to nutrition, avoid exposure to tobacco, alcohol, pesticides, harmful chemicals, radiation, etc., and avoid taking drugs that can cause fetal malformations. The expected date of delivery can also be calculated based on menstruation, which is very beneficial for pregnancy health care and psychology.

3. It can prevent excessive iron content.

In medicine, there is a hereditary disease called hemochromatosis. The chance of organic damage caused by hemochromatosis in women is much lower than that in men, or even almost never occurs. The main reason is menstruation, because the cyclical blood loss during menstruation consumes excess iron. Hemochromatosis can easily cause iron metabolism disorders in patients, resulting in excessive accumulation of iron in the body; excessive iron can slowly lead to lesions in the skin, heart, liver, joints, pancreatic islets, etc. One way to treat iron overload is to drain your blood regularly.

4. It can help women detect diseases earlier.

If a girl is over 18 and still has no menstruation, or if a woman has had normal menstruation in the past but has not had menstruation for more than three months (excluding those caused by pregnancy, breastfeeding, and menopause), she should be checked for lower reproductive tract atresia, congenital absence of uterus or uterine hypoplasia, ovarian tumors, pituitary tumors or dysfunction, endocrine or wasting diseases. In addition, changes in menstrual timing, volume, and accompanying symptoms are also important clues for discovering and diagnosing many diseases, so we must pay attention to menstruation.
