What is Menopause?

Induced Menopause

There is another type of menopause called induced menopause. Induced menopause can happen when the ovaries are removed during surgery (surgical menopause) or when damage occurs to the ovaries by radiation or chemotherapy. When the ovaries are removed or severely damaged  (ovaries help produce hormones in women), the woman will often experience menopausal symptoms because of an abrupt interruption in the amount of hormones produced in her body.

Surgical menopause symptoms generally occur soon after surgery and are often more severe than symptoms experienced in natural menopause.2

Definitions related to induced menopause (taken from North American Menopause Society)

Hysterectomy. Surgical removal of the uterus. Does not result in menopause, but ends menstrual periods and fertility. The term is often mistakenly used to describe removal of the uterus and both ovaries, which results in surgical menopause.

Surgical menopause. Induced menopause that results from surgical removal of both of the ovaries (bilateral oophorectomy) for medical reasons. Surgical menopause can occur at any age before spontaneous menopause. See also Bilateral oophorectomy, Induced menopause.
