Menstruation in girls generally lasts for a few days Why do women menstruate

Generally speaking, most women's menstrual period is about 3 to 7 days, and the menstrual period is too short or too long is an abnormal manifestation, which should be paid attention to and go to a regular hospital for examination and treatment in time.

Menstruation, which can be said to be something that every woman needs to go through in her life, is an important part of normal women's physiological changes. Many women are troubled by the arrival of menstruation, but if it does not come, women will be more restless and anxious, because it may mean that something is wrong with the body, orpregnantFinish. So, why do women return to menstruation? How many days does a woman's menstrual period usually last?

The reason why women menstruate is related to the changes in the hormone level in the female body, the proliferation and shedding of the endometrium, and ovulation of the ovaries, but the most direct reason is the shedding of the endometrium.

Generally speaking, a woman's menstrual cycle is 28 days, during these 28 days, the estrogen and progesterone in the woman's body will fluctuate to a certain extent, when estrogen reaches its peak, it is also the time when the endometrium is the thickest, at this time the ovaries will also ovulate, followed by the stage of gradual growth of progesterone. If the egg released from the woman's ovaries does not meet the sperm to form a fertilized egg, then the egg changes and degenerates, and the corpus luteum in the ovaries will also undergo certain changes, resulting in a decrease in progesterone levels, which will then lead to endometrial ischemia and necrosis and shedding. This forms menstruation.

Most women's menstrual period is about 3 to 7 days, and short or long menstrual periods are abnormal manifestations, which should be paid attention to by women and go to the hospital for treatment in time. Of course, for women who have just entered puberty, because the HpO axis in the body is not yet stable, there may be irregular menstrual periods, etc., and generally after 1-2 years of self-adjustment, it will return to normal.

I have a general understanding of the production of menstruation and the duration of menstruation. Generally speaking, the duration of a woman's menstrual period is about three days to seven days, and a menstrual period of less than three days or longer than seven days indicates that a woman may have some diseases, which should be paid attention to and promptly go to a regular hospital for examination and treatment.
