The menopause, also known as the 'change of life', simply means the end of menstruation. The term is also used to refer to the months and years in a woman's life before and after her final period a time that is likely to bring with it some physical and emotional changes.
The menopause is usually a gradual process. The ovaries begin to produce lower amounts of hormones, which cause menstrual periods to become irregular and eventually to stop completely. The fluctuating levels of hormones also contribute to other symptoms that may occur at this time, such as hot flushes and night sweats.
Most women menstruate for the last time at about 50 years of age, although a few do so as early as 40 and a very small percentage as late as 60. With the average life expectancy of Irish women now at around 80 years of age, this means that one-third of an Irish womans life may take place after their menopause. Women who smoke undergo menopause about two years earlier than non-smokers.
Most women notice some menstrual changes such as shortening of cycle length (periods occurring closer together), skipped menstrual periods and occasional heavy periods up to a few years before menstruation ceases. Menopause can often occur at a time in life when other dramatic changes are taking place, such as the loss of parents, adjustment to children growing up and leaving home, or retirement. These changes, in addition to the changes in your body, may result in psychological or emotional stress.
A premature menopause (before age 40) can sometimes occur and may be due to a number of different reasons, for example, surgical removal of the ovaries.
You may have both physical and psychological symptoms during menopause. Most of the physical symptoms are due to the reduction in levels of the hormone oestrogen. Symptoms may occur for a few weeks, a few months, or sometimes over several years. Your symptoms may come and go, or they may occur regularly. Some common symptoms are:
The drop in oestrogen levels that occurs in the menopause can have a number of long-term effects. Before the menopause, oestrogen protects women against the condition atherosclerosis (hardening of the arteries) a major cause of heart attacks and strokes. The menopause is therefore associated with a rise in incidence of these diseases.
Oestrogen deficiency is also associated with osteoporosis a condition in which there is a gradual thinning of the bone, leading to increased risk of fractures. Lack of oestrogen accelerates the loss of bone that occurs in this condition.
Women may also find that they suffer from more infections of the bladder (cystitis) after the menopause. This is due to a reduction in acidity in the vagina, which can make it easier to contract infections.
Menopause is most commonly diagnosed on the basis of your symptoms and medical history. Your doctor may conduct tests to eliminate other causes of your symptoms if necessary, for instance, with blood or urine tests.
Menopause is a natural part of a woman's life cycle. It is not a disease and does not necessarily require any treatment. However, many women choose to take medications, such as Hormone Replacement Therapy (HRT) in order to relieve their symptoms.
HRT may contain either oestrogen only or a combination of oestrogen and progesterone. It may be prescribed in the form of tablets to be swallowed, patches to be applied to the skin, or a cream to be inserted into the vagina.
There has been concern in recent years about a possible connection between the use of HRT and an increased risk of heart disease and breast cancer. Because of this, HRT is now only recommended for short-term treatment of menopausal symptoms, when the benefits are considered to outweigh any risks. It is not considered to be suitable for long-term use, e.g. for the prevention of osteoporosis. You should discuss the pros and cons of HRT with your GP.
There are other medications that may help to relieve the individual symptoms of the menopause e.g., the hot flushes, vaginal dryness and stress incontinence.
There are also other ways to help prevent osteoporosis for example, you can take calcium supplements and exercise regularly, and there are a number of different medications that can be used in its treatment. See our article on osteoporosis for more.
Exercise and eating healthy foods may also help with some of the unpleasant side-effects of menopause. Eating foods high in plant oestrogens, such as soya beans and lima beans, may alleviate symptoms. Other sources include nuts and seeds, fennel, celery, parsley and flax-seed oil.
Improve your diet
Use birth control during sexual intercourse until your doctor says that you may stop. It is not possible to know exactly when you will stop being able to get pregnant and pregnancies for women in their later 40s carry higher risks of medical complications for mother and baby and also a higher risk of birth defects in the baby.
Look for support
Talk to a friend or family member who understands what you are experiencing. Discuss the problems with your doctor or practice nurse.
