Ima ge des crip Menopause - premature and early menopause Menopause occurs when a woman stops ovulating and her monthly period (menstruation) ceases. Most women reach menopause between the ages of 45 and 55, with the average age around 51. However, about one per cent of women experience menopause before the age of 40 years. This is known as premature menopause or premature ovarian insufficiency (POI). Menopause between 41 and 45 years of age is called early menopause. In some cases, early menopause is brought on by surgery to remove the ovaries or by medical treatments such as radiation therapy and chemotherapy. In other cases, the woman’s ovaries spontaneously stop producing eggs and the underlying cause may not be found. For most women, the loss of their fertility is devastating, particularly if menopause occurs before they have had children. Most women will experience a long period of postmenopausal life. Hormone therapy (HT) – also known as hormone replacement therapy (HRT) – may be advised to counteract the health risks of early or premature menopause such as early onset of osteoporosis and cardiovascular disease. Symptoms of premature and early menopause The symptoms of early menopause are the same as for menopause at the typical age and can include: menstrual cycle changes, including changes to the usual bleeding pattern, particularly irregular bleeding hot flushes sweats urinary problems, such as incontinence or increased frequency of urination dry vagina mood changes weight changes aches and pains. Causes of early or premature menopause Premature menopause means the woman’s ovaries have spontaneously stopped working before she has reached the age of 40 years. Women can be affected in their teens or early 20s: About one in 1,000 women may reach menopause before the age of 30. Some possible causes include: Unknown causes – in the vast majority of cases, the cause can’t be found. This is known as idiopathic premature menopause. Autoimmune conditions – about 10 to 30 per cent of affected women have an autoimmune disease such as hypothyroidism, Crohn’s disease, systemic lupus erythematosus or rheumatoid arthritis. Genetic conditions – such as familial ovarian failure (FOF) and rarely galactosaemia. About five to 30 per cent of women have an affected female relative, which suggests a genetic link, such as: Galactosaemia is when the body cannot convert the carbohydrate galactose into glucose. It is thought that the unconverted galactose could be toxic to the ovaries. Conditions characterised by enzyme problems, such as congenital adrenal hyperplasia, can also bring on premature menopause.
