The menopause is when a woman stops having periods and is no longer able to get pregnant naturally.
Periods usually start to become less frequent over a few months or years before they stop altogether. Sometimes they can stop suddenly.
The menopause is a natural part of ageing that usually occurs between 45 and 55 years of age, as a woman’s oestrogen levels decline. In the UK, the average age for a woman to reach the menopause is 51.
However, around 1 in 100 women experience the menopause before 40 years of age. This is known as premature menopause or premature ovarian insufficiency.
Most women will experience menopausal symptoms. Some of these can be quite severe and have a significant impact on your everyday activities.
