Patient's question:

Menopause definition

Doctor's answer:

A female patient after the age of 45, the ovarian function gradually declines, and when the levels of estrogen and progesterone drop, menstrual cycle disorders may reappear, eventually leading to a gradual cessation of menstruation. Generally, if menstruation ceases for more than a year, it can be referred to as menopause. Some individuals may still experience occasional menstrual periods one year or more after menopause, as long as the bleeding is not excessive and subsides within a week, it is not a concern. However, if the bleeding is heavy and does not stop within a week, it is necessary to investigate the underlying cause.
