How many days does it take for a normal woman to menstruate?

Normal female menstruation usually lasts 3-7 days. Menstrual cycles and period length vary from person to person and are affected by factors such as hormone levels and endometrial thickness.

Menstruation is the physiological phenomenon of periodic shedding and bleeding of the lining of the uterus in women. Most women's menstrual period lasts for 3-5 days, and the bleeding volume is between 20-60 ml. Menstrual blood may be dark red at the beginning, gradually turn to bright red, and later turn to brown. The amount of bleeding is heavy on the 2nd to 3rd day of menstruation, and then gradually decreases. After the endometrium is completely shed, menstrual bleeding stops and a new cycle begins. The regularity of menstrual periods is closely related to ovarian function. Women with normal ovulation have relatively stable menstrual periods. Menstrual periods that are too short or too long may indicate hormone imbalance, endometrial lesions and other problems.

If menstruation lasts for more than 7 days or less than 2 days, it is recommended to observe 2-3 cycles. When accompanied by abnormal menstrual flow, severe dysmenorrhea or cycle disorders, polycystic ovary syndrome, uterine fibroids, thyroid dysfunction and other diseases need to be investigated. You can record your menstrual cycle, menstrual volume and accompanying symptoms on a daily basis, and avoid strenuous exercise or bathing during menstruation. Maintaining a balanced diet and supplementing with iron and protein in an appropriate amount will help maintain normal menstrual function.
