N95: Menopausal and other perimenopausal disorders

N95.9: Menopausal and perimenopausal disorder, unspecified

The menstrual cycle is controlled by specific sex hormones. These hormones are produced in the ovaries. The ovaries are part of the female genitals. There are two ovaries, one on each side. The ovaries sit low down in the abdomen. Egg cells mature in the ovaries. The egg cells can later develop into a child. The ovaries also produce various messenger substances. Messenger substance is another term for hormone.

There is sharp decrease in the levels of sex hormones produced between the age of 45 and 55. As a result, periods become irregular and cease completely at some point. The period during which the hormone levels change is called the menopausal transition. The menopausal transition may continue for several years after your last period.

You can have a number of different symptoms during the menopausal transition. For example, you might suddenly have hot flashes or sweat profusely. Your mood might change, or you might have problems sleeping.
