Almost three quarters of women who are about to start the transition to menopause notice some kinds of symptoms. Menopause symptoms are a result of changing hormonal levels. This is in preparation for the shutdown of the female reproduction system. As hormone production decreases, most women will start to have symptoms even if their periods haven’t stopped.

The menstruation cycle comes to an end permanently when a woman goes through menopause. Women, on average, go through menopause at the age of 51 in the USA. On a world wide basis there is no average age for women who go through menopause, this is due to differing health care and nutrition.
