The menopause is a natural part of the ageing process for women. It normally occurs between 45 and 55 years. The menopause is caused by a reduction in oestrogen levels that eventually stops women from ovulating causing their periods to stop. It is the reduction in oestrogen that triggers unpleasant symptoms of the menopause including vaginal dryness, hot flushes and low libido. Hormone Replacement Therapy (HRT) is used to treat symptoms of the menopause. There are now lots of options available including tablets, patches and gels, to help women find a medication that suits them.
