The menopause occurs as a natural part of the female life cycle, usually between the ages of 45-55 years, signalling an end to the fertile years.

In women over the age of 45 years, production of the hormone oestrogen by the ovaries gradually comes to a halt. During this time, the female body has to adapt from a life heavily influenced by oestrogen and the menstrual cycle, to a life devoid of this hormone. This decline in oestrogen results in menopausal symptoms, which may last for just a few months or linger on for several years.
