HOW TO KNOW WHEN MENOPAUSE IS COMING

Menopause, that biological milestone in our lives, typically announces its impending arrival by menstrual irregularity, fatigue, hot flashes and night sweats. There are also subtle physical and psychological symptoms that we experience, culminating in the end of the familiar monthly menstrual cycle. If you are experiencing any of these symptoms or are approaching 40 to 45 years, it is wise to discuss these issues with your doctor.

Strictly defined, the very last day of menstruation is called menopause after it has stopped for a period of twelve months. This end of menstrual cycling usually occurs between the ages of 40 and 60 years, with the average age being 51. Menopause can be a welcome relief from the fear of pregnancy and painful or irregular bleeding often accompanied by menstrual migraine and premenstrual tension. Women are unique beings who, unlike females of other species, continue to live long after the end of their fertility. In the 1990s, a woman can look forward to another 30 years or longer after her menopause, because of the advances in medical science and better socioeconomic conditions.

This end of the reproductive years is known by various names — the change, the climacteric and, most popularly, menopause. The word menopause is derived from two words - the Greek meno meaning month and pause meaning cessation. Although menopause technically refers to that one day in a woman’s life when her periods stop, the effects of that loss of reproductive (ovarian) function extend over years, both before and after, that one day. The word climacteric is used to define these years of physical and emotional changes.

Since the duration of these midlife changes is about 20 years in the context of chronic illness, endocrine disorders, menstrual problems, fertility problems; about ten years ago 2001 it was decided to study the changes of the reproductive aging. The scientists of five different countries and multiple disciplines sat to classify them into different stages. After ten years a more comprehensive basis for assessing reproductive maturity is described. The first stages are like normal reproductive function with regular menstrual cycle, later in this stage the cycles can sometimes be irregular, the fertility decreases and the main pituitary hormone for the maturation of the egg (FSH) can increase. At this stage the patient can have some symptoms such as hot flashes in the premenstrual stage, and premenstrual tension. In the following stages often called perimenopause when the menstrual cycle varies the fertility decreases. The hormone studies are often done especially in women who are anxious to have a baby late in life. The FSH is variable. The two other hormones which we have not elaborated on are called Antimullarian and Inhibin B are low. The number of maturing follicles in the ovary is low. The women start having hot flashes. In the later part of this perimenopause the FSH is usually high( Should be done on the second day of the cycle) and the symptoms become pronounced.

In the final stages of this menstrual cycle stops and when it has stopped for one year it is called menopause and the FSH is usually high, and Antimullarian Hormone and Inhibin B is very low. The chances of pregnancy are almost nil. Personally I have seen two women having a baby at 54 and 56 years of age. Later on these women start getting symptoms related to external genitalia (Painful dry vagina, painful sex) and urinary symptoms, such as poor control and repeated urinary infections. Recently this has been studied and called pelvic syndrome of menopause, these late symptoms get worse and never improve. Many clinicians call these changing years as menopause transition. I agree this system of classifying the reproductive aging is very useful as we have no international diagnosis of menopause syndrome. It is mainly based on menstrual cycle, ovarian aging and supportive criteria. Depending on your menstrual cycle symptomatology and supportive criteria you can assess when your menopause is coming irrespective of your age and nationality. 

Surgical menopause

The surgical removal of both ovaries (called bilateral oophorectomy) is sometimes necessary in the treatment of breast cancer or other conditions. Such removal of the ovaries results, of course, in the sudden loss of a woman’s ovarian hormones, and produces a surgical menopause. The symptoms that result from a surgical menopause can be every bit as distressing as, and sometimes even more than, a normal menopause.

Hysterectomy (the surgical removal of the uterus) does not induce a true menopause, because, although the periods stop, the ovaries continue to manufacture the female hormones in the normal cyclical way.

Menopause sometimes occurs about five years earlier in women who have had a hysterectomy and in women who smoke. For these women, menopausal symptoms, rather than the cessation of periods, herald the start of menopause. For some women, a blood test may be needed to confirm menopause.

Premature menopause

If menopause happens before 40 years of age it is called premature menopause. If it happens very early, for example, in the 20s, it is called ovarian failure rather than premature menopause. For younger women who have no periods for any length of time and are having symptoms, premature menopause is a possible explanation. Of course, pregnancy is also a possibility and it is therefore essential to exclude pregnancy before attributing the absence of periods to premature menopause.

Personal story

Premature menopause causing psychological stress

Gina, a 22-year-old law student and keen sportswoman of Italian descent, was a classic case of premature ovarian failure. She had not had a period for five months and she had occasional hot flushes. Her general practitioner who believed that her strenuous sports activity had caused her periods to cease referred her to a gynaecologist. Absence of periods often happens with excessively physically active young women involved in sports, gynmastics and aerobics. Simple emotional stress which affects young women can also cause infrequent or absent periods. However, various hormone blood level tests showed that she was suffering from premature menopause (premature ovarian failure). Gina took consolation from the rapid strides being made by the IVF fertility program which may eventually provide a solution to her problem. Immediately though, the answer was for her to go on HRT

Gina is having psychological counselling to cope with the devastating consequences of possibly never being able to have a child.

Women reaching middle age may experience several other problems unrelated to menopause or oestrogen deficiency. Problems of ageing such as arthritis and diseases such as diabetes and high blood pressure, often start at this time. Many social and psychological barriers also arise. A lack of career fulfillment, ageing parents to care for, marital disharmony and difficulties with growing children all create additional stress. The problems at middle age are therefore often a combination of biological (ageing and menopause), psychological and social upheavals.

 Specific menopausal symptom

Menopausal problems can be short-term or long-term. Hot flashes are the most obvious distressing symptom which brings a woman to a doctor. Other symptoms are general sweating, night sweats, muscle aches and pains, joint pains and a peculiar sensation of ants crawling on the skin called formication. A second group of symptoms include urogenital changes, manifested by dryness of the vagina, bladder problems such as the frequent desire to empty the bladder, and the loss of bladder control. These symptoms are due to atrophy (thinning) of the vagina and the urethra resulting from oestrogen deficiency. A third group of symptoms embrace psychosomatic ailments of confusion, loss of self—image, loss of memory, agitation, irritability, headaches not previously experienced and depression.

Long-term, postmenopausal women suffer an increased incidence of heart disease, a thinning of their bones (osteoporosis) and atrophy of the genital organs. It has been shown in studies that only 3% to 4% of women seek medical advice about these issues at this time.For treatment to be effective, it is important to distinguish between oestrogen deficiency symptoms and those caused by other problems.

Hot flushes

A hot flush is a sudden transient feeling of heat over the head, neck and chest, starting from the chest. It causes flushing of the skin which is obvious to other people. What causes a hot flush is not clearly understood, but it is likely to have something to do with the hypothalamus, a key nerve centre iii the brain. The reduced oestrogen levels irritate the neuroreceptors in the hypothalamus and these in turn signal the blood vessels in the skin to dilate. The increased blood flow through the dilated vessels heats up the skin, and causes the flush, While the skin temperature is rising during the several minutes of the flush, the body temperature drops by a few degrees. The cooling effect is accentuated because a chill feeling follows the evaporation of the newly formed perspiration from the skin. As a result of cooling, our body’s defence mechanism takes over and the adrenal gland releases a hormone called adrenaline. This stress response causes constriction of the blood vessels, and the hot flush ends.

The number of hot flushes women experience is variable. There may be several in a day, several a night or they may be continuous, one after another. Night sweats are the same phenomenon as hot flushes except that they occur during the night. Because they occur during sleep, the hot flush is not felt as much as the consequent cold sweat.

While hot flushes usually occur spontaneously, they may also be initiated by external factors such as sudden unexpected noise or a fright. A stressful work or home environment can greatly increase the frequency and severity of hot flushes. They do not have any serious long-term effects, although some of the insomnia and fatigue that occurs at menopause may be caused by the night sweats.

These symptoms are the commonest of menopausal problems. About seven out of every ten menopausal women experience hot flushes and more than 60% experience hot flushes for 12 months after menstruation stops. Hot flushes often continue for several years after menopause. For many women, they start a few years before their periods actually stop; that is, during the time when they are experiencing menstrual irregularities.

Hot flushes can be a very distressing condition. A general consensus is that hot flushes undermine a woman’s self-confidence making her self- conscious of her body in a negative way. They are a contributing factor to the psychological symptoms accompanying menopause.

Formication or the sensation of crawling under the skin is generally due to vascular changes of the skin early in menopause. Some more unusual symptoms include tingling in the ears and dizziness. Hormone replacement therapy (HRT) can bring dramatic relief from these symptoms within days.

Fatigue

Fatigue is a very common problem during menopause. There are several general causes for tiredness which should be excluded before associating it with menopause. For example, menstrual irregularities and heavy periods causing anaemia (lack of haemoglobin in the blood) can cause tiredness. An often overlooked cause of fatigue is poor diet and the stress of the daily demands of being a mother, running a home and a job at the same time.

It is important to evaluate your working hours and conditions before attributing fatigue entirely to menopause. It is also important to exclude any other disease or biological changes which may be responsible.

Urogenital symptoms

These symptoms occur three to eight years after menopause. They mainly affect female urinary activity and genital function. Lack of oestrogen is the main reason for changes in the urinary and genital tract. After menopause, there is a progressive deterioration in these functions, ultimately causing a dry, shrinking vagina which leads to diminished capacity and elasticity. Sexual stimulation is also diminished and it takes longer to reach orgasm. Vaginal atrophy and dryness varies from woman to woman. Larger women are less seriously affected because their body fats continue to produce and store an oestrogen called oestrone. Lack of oestrogen seriously affects urinary performance because the urinary bladder is believed to be oestrogen dependent.

Initially, there may be repeated infections (cystitis), frequency and urgency and some stress incontinence (spilling of urine under stress such as coughing, sneezing, laughing or dancing). As the years go by, these symptoms can become more serious and incontinence can become a great handicap.

In caring for the geriatric population, incontinence is a major determining factor in finding accommodation in nursing homes. The most common urological complaint a gynaecologist deals with is incontinence. For younger women, it is generally stress incontinence and, for older women, it is generally due to overflow. Difficulty in emptying the bladder completely is another problem experienced by elderly women.

The important role played by oestrogen in the proper functioning of the urinary system is not completely clear. The lack of oestrogen, together with a generalised loss of muscle tone, are the major factors in compromised urinary function after menopause. However, while oestrogen replacement helps many women with such difficulties, it does not help all. Thus, other causes of this particular symptom should be considered and treated accordingly.

Irregular or absent menstrual cycles

By definition, menopause is the end of the menstrual cycle. However, before menopause arrives, irregularity of cycles is common. Irregularity can be frequent periods, infrequent periods, too much bleeding or too little bleeding. The reason is that the failing ovaries are not ovulating;; there is no progesterone produced to ripen the lining of the uterus (the endometrium) and regulate the menstrual cycle. This is perhaps the earliest symptom of menopause and is often not recognised as such.

In the past, many women in their late 30s and early 40s who consulted their doctor about irregular periods were described as suffering from dysfunctional bleeding. This term means abnormal uterine bleeding in the absence of any uterine fibroids or other medical reason. The bleeding is generally due to a hormonal imbalance.

Other causes of abnormal bleeding and absent periods should be excluded before labelling this as menopausal. These problems can be due to a range of causes varying in severity from simple fibroids to uterine cancer or even pregnancy

Muscle and joint aches and pains

After the ovaries begin to fail, the ligaments and tissues which connect various parts of the skeletal system become lax resulting in decreased muscle strength. The looseness gives rise to a variety of aches and pains. Laxity of the muscles is accompanied by loss of elasticity of the ligaments and the cumulative effect is more aches and pains in the shoulders, elbows and back.

With age, we can also expect some degree of osteoporosis and consequent pain. Osteoporosis can cause fractures of the vertebrae and then curvature of the spine. When the curvature is very marked, it is known as dowager’s hump and results in loss of height.

With an adequate amount of physical activity, these symptoms are prevented as exercise enhances the wellbeing of the muscles, ligaments and the bones. Oestrogens are also believed to have some benefic all effects as an anti-inflammatory agent thus preventing pain as well as preventing osteoporosis.

A combination of lack of oestrogen, poor physical activity and menopausal changes exacerbate muscle aches and pains. Many women are treated as if they suffer from osteoarthritis and are often given aspirin and other non—steroidal anti-inflammatory drugs which can cause side—effects such as stomach ulcers.

Other symptoms

As the ovaries fail, there is a relative proportional increase of the male hormones, androgens, mainly testosterone and androstenedione. These hormones can lead to the appearance of pimples and facial hair, and the thinning and loss of scalp hair. HRT can improve these distressing conditions. Sometimes, a drug, Aldactone, can be used to neutralise androgens and decrease facial hair

Skin and hair

The skin constantly changes with age due to deterioration from excessive exposure to sun. The ageing of the skin starts at about 30 years. These changes are accentuated by the hormonal changes at menopause. At this time, the elastin and collagen in the skin decreases although it is not yet understood why. The loss of collagen, in the initial years of menopause is far more than in subsequent years. The deficiency of elastin and collagen causes wrinkles and dryness. Women who have been on prolonged corticosteroid therapy, or who suffer from adrenal disease, have diminished collagen tissue. Corticosteroids, commonly used for asthma, have an adverse effect on skin and bones.

HRT can be beneficial. Oestrogen and testosterone help the skin by protecting the loss of collagen and elastin, increasing the skin’s water content (called “hydration”) and improving blood circulation. Recent research has shown that skin changes often almost disappear within six months of starting HRT, after which there is no further significant improvement as there is an optimum collagen content that women achieve.

Acne at menopause can be treated by general cleansing of the skin, by nutritional creams and by HRT which restores the hormonal balance in favour of oestrogen. Some doctors use aldactone to neutralise the testosterones. This may result in side—effects such as depression, diminished sex drive and a tendency to a husky voice. These drugs have a place when acne is very severe.

At menopause, new facial hair can commonly appear. HRT can lessen facial hair. In severe cases, medication is prescribed for a few months at a• time. Simple depilatory creams may be used. Baldness is rarely seen in menopausal women; if it does occur, it is important for your doctor to:: exclude other causes of hair loss.

Care of our skin is important at any age. Australia has the world’s highest incidence of skin cancer. Avoid unnecessary exposure to the sun by using a broad-brimmed hat, wearing a long-sleeved top and using a SPF-15-plus protective sun cream every day

Other simple measures for skin care include correct diet and lifestyle factors such as reducing your intake of fat and salt, eating plenty of raw fruits and vegetables, drinking plenty of water, quitting smoking and cutting your alcohol consumption. Other positive aids to the good health and wellbeing of your skin are regular washing, gently massaging your skin with one of the many specialised skin brushes and using moisturising creams.

Personal story

Distressing male pattern hair distribution and hair loss

Claire, 49, a shop assistant, cried as she took off her hairpiece concealing a large bald patch. She described how she had been embarrassed and dismayed by her creeping hair loss over two years from menopause and chronic emotional stress. She was reassured that HRT could prevent the condition worsening and might even improve it. She was prescribed a hormonal combination of oestrogen and progestogen to combat the testosterone, the biological culprit. After eight months of HRT, her hair loss stabilised.

Formication

Formication is the sensation of crawling under the skin. The feeling is caused by vascular changes in the skin at the time of menopause. The condition usually improves or completely disappears soon after starting HRT Some more unusual symptoms include tingling in the ears, dizziness, painful leg cramps and a bloated feeling.

Emotional disturbances

Psychological disturbances which many menopausal women commonly complain of are depression, insomnia, panic attacks, mood swings, irritability and lack of self-confidence. These feelings often appear before the symptoms of hot flushes. Short-term memory loss is also complained about but this may be more age related because it also affects men.

Although HT relieves these symptoms for many women, there is no conclusive proof that these symptoms are the direct result of oestrogen withdrawal. Many women seek to blame oestrogen withdrawal when their real problems may be stress related at home or work. At this time of life, women are prone to fretting about their changing body shape, weight gain, sagging breasts, wrinkles around the eyes, career unfulfillment, problem children and a disappointing marriage. Emotional symptoms from the time of menopause are very difficult to classic and may be unrelated to lack of oestrogen.

With our present state of knowledge, we are unable to explain how and why HRT can give many of these women relief from their emotional symptoms. Some of this improvement may be the result of the tranquility they achieve from HRT’s correction of their hot flushes. However, there is an equal number of women who pass through menopause without any emotional trauma.

Premenstrual syndrome (PMT) is a group of symptoms which affects women in their third and fourth decade, ultimately merging with perimenopausal symptoms. It is a stressful combination of physical and psychological symptoms which occurs regularly before the start of menstruation. Symptoms can include headaches, irritability, depression, mood swings, menstrual migraine and suicidal tendencies. There can also be poor performance, clumsiness, changes in weight, tender breasts and fluid retention. The exact cause of PMT is not known.

Personal story

Persistent headaches which, in reality, were hot flushes

Joan, a hotel chef, who had a hysterectomy and removal of both ovaries at 36 because of severe infection from the Dalkon Shield complained to her doctor of headaches. Six months after her operation she began to suffer persistent headaches which were actually hot flushes. Various doctors considered the condition to be persistent headaches which were not relieved by pain killers. She was referred to a dentist who believed the malalignment of her jaw was causing the persistent pain.

Finally, she started taking HRT and within two weeks felt better.

Personal story - Hot flashes, insomnia and lack of concentration

Janet, 51, an architect, was worried about her mood swings, difficulty in concentrating, lack of sleep and unpredictable hot flushes. Her menstrual cycle, for the past 18 months, had become irregular and her last. menstrual period was four months ago. Her past medical history was unremarkable except that she had had varicose veins surgically removed from both legs.

She had not taken any medication in the past. Her father died of coronary heart disease at the age of 56 after several years of suffering from angina which had also afflicted her mother. Her menopausal status was suspected from her irregular menstrual cycle and symptoms and was confirmed with an elevated FSH level by her blood test. HRT was recommended to control her symptoms and to prevent her from developing heart disease because of her family history which put her in a high risk category

Key points

1.     After menopause the oestrogen levels progressively decline, causing several permanent changes. Menopause is not a transitory phase, but a permanent one in your life because the oestrogen deficiency is permanent.

2.     Symptoms of menopause are many and varied, extending from psychological to physical manifestations. The commonest are hot flushes, irregular bleeding, vaginal dryness and mood swings. Menopausal symptoms are not a universal experience for women.

3.     Symptoms can start many years before and continue many years after your last menstrual period. If you are experiencing any of these symptoms, it is wise to discuss them with your doctor, particularly one with a special interest in menopause

4.     There’s no conclusive evidence to suggest that menopause causes any psychological problems. Many women claim that HRT helps their mood changes, energy levels and memory

5.     The health of a woman’s skin is linked with her overall oestrogen supply, in a similar way to that of her bones.

6.     These symptoms can occur for many reasons. All possible causes should be looked for, and excluded, before HRT is started.

7.     HRT 15 the focus of the effective treatment of menopause. However, about 15% of women do not require therapy because they are still capable of making some oestrogen.
