Menopause is the time in a woman's life when her periods (menstruation) eventually stop and the body goes through changes that no longer allow for pregnant. It is a natural event that normally occurs in women age 45 - 55. And for some women can be incredibly upsetting and emotionally traumatic. Not to mention the sometimes extreme side effects of menopause that can last years.
The first thing most women notice is that periods start to change. They become irregular and might occur more or less often. Irregular periods can last for 1 - 3 years before the periods completely stop.
