How many years is it normal for a woman to have her period in her lifetime.

Patient's question:

No

Doctor's answer:

The menstrual cycle in women is characterized by the periodic shedding and bleeding of the endometrium, which occurs alongside the cyclical changes of the ovaries. The age of menarche (the first menstrual period) for most women falls between 12 and 14 years old. Throughout their lives, women typically experience menstruation for about 30 years. After the age of 40, ovarian function gradually declines, estrogen levels drop, and women enter the menopausal transition period.
