This widely acclaimed book is based on the one question most asked by women who are experiencing menopause - is hormone replacement therapy necessary? Experience has shown gynaecologist Dr Margaret Smith and psychotherapist Patricia Michalka that not all women need or want hormone therapy during menopause and, indeed, not everything that happens at this time of life is due to hormones. In this book, the authors use women's experiences (including their own) to explain how to sort out the confusion caused by the interaction of hormones and life events. their writing contains practical guidance-both medical and psychological-and reflects the rich tapestry of many women's lives with all their humour, confusion and clarity.

Is It Me Or My Hormones? - Margaret Smith



Over the last seven years or so, the question ‘Is HRT dangerous?’ has evoked major debate. Media headlines about a possible increase in breast cancer and cardiovascular risk in women on hormone replacement therapy (HRT) have alarmed and confused menopausal women. Many have stopped HRT but are still seeking help for the significant changes that occur around this time. For some women there is a need for appropriate HRT and in taking HRT they need reassurance that improved quality of life need not be at the expense of quantity of life. This book imparts information that should provide this reassurance, including the most up-to-date research on breast cancer and cardiovascular risk.

In the sixties, women in the USA were persuaded to undertake estrogen replacement therapy (ERT) under the catchcry ‘feminine forever’. In the seventies, the concern that estrogen alone may increase the risk of cancer of the uterine lining (endometrial cancer) caused doctors to think again about the risk–benefit ratio of hormone therapy. In the eighties, progestogens were introduced and ERT became HRT, meaning that both hormones were given to women during menopause. At that time it was believed that such therapy had positive effects on the cardiovascular system and so would provide primary protection against heart attack and stroke. Studies had already shown that HRT could protect bones from the loss of calcium caused by estrogen deficiency and thus prevent osteoporosis, so many women decided to take HRT long term for all these benefits. It was also believed that HRT could improve brain function.

In the nineties came warnings of a possible increased risk of breast cancer for women on HRT for longer than five years and then studies that showed that HRT given to women who had already had a heart attack or stroke did not give protection against a further stroke. Further studies of older women (who did not have menopausal symptoms) showed that quality of life was not improved for these women by giving HRT and nor did HRT protect against loss of brain function.

All these studies were done on women using the standard HRT therapy in the USA – Premarin and Provera. However, in Australia, lower dose estrogens and different progestogens were prescribed by many doctors.

Today, it is generally believed to be appropriate for women to use HRT short term (i.e. for two to five years) for the relief of classic menopause symptoms, but the catchcry ‘feminine forever’ needs revision. It is important to use HRT judiciously and appropriately, and its use must be based on individual need and assessment.

‘Is it me or my hormones?’ is the question most commonly asked by women in their middle years. One woman in midlife said it all when she exclaimed, ‘If it’s not menopause then I must be going insane.’

In this book we explain how symptoms due to hormone deficiency need to be differentiated from symptoms with medical or emotional causes so that appropriate treatment can be given.

Hormones begin to change and then decline from 35 to 55 during what is called perimenopause. We have therefore included stories from women of all these ages, not just from women who are going through menopause.

In the medical world, before 1960, menopause was hardly mentioned. Now it is acknowledged, although some critics believe that the medical profession has attempted to take over this natural process, which is known as the medicalisation of menopause. Management of menopause benefits from appropriate medical assessment, including mental and emotional factors as well as the physical. Menopause is neither a medical nor a mental condition, but a natural stage in life that all women go through, although it may be associated with medical problems. About 50 percent of women have no physical or emotional trouble at all. However, many women do need emotional support and counselling, but they are not being heard, nor are they having their questions answered.

We all change and we all go through many changes, but for many women ‘the change’ (i.e. the menopause) is a time of huge significance. For some women it is just another step on the journey, marked only by the calendar and the absence of periods. For a small minority it is almost a death before death, with sweeping changes, both physical and emotional, which are barely tolerable. Virginia Woolf asked the question: ‘Why is life so tragic, so like a strip of pavement over the abyss? I look down: I feel giddy: I wonder how I am ever able to walk to the end.’ She suffered from depression for most of her life, but this became untenable around menopause and she finally took her own life. It was a long-standing inner (endogenous) depression related to childhood and teenage distress.

For most women menopause doesn’t have to be as overwhelming as Virginia Woolf’s experience, but there may be similar long-standing psychological distress that has been covered over or ignored. In fact, it is often the women who have coped and managed to keep at bay the little ‘life messages’ and ‘taps on the shoulder’ that have happened through the years who have quite a stockpile of issues waiting to be dealt with at this very important time. Midlife vulnerability tends to expose this. We have seen some women start a new life and others lose their way altogether at menopause, and it is too easy to blame everything on our hormones.

Another frequently asked question is ‘When does menopause start?’ The usual age is between 45 and 55. The average age of menopause (which is when the last period occurs) is 52, but at whatever age periods cease, twelve months with no periods must elapse before we can call this the last period. However, younger women in their mid-thirties and forties who are still menstruating may note physical and emotional changes that they think could be early menopause though by definition it is not. This is also discussed in later chapters.

Hormone deficiency is only one aspect of menopause; therefore, HRT is only one aspect of management. Other medical conditions may need to be defined and treated. If the main problem is emotional, women need a sympathetic hearing, some need psychological help and others may need psychiatric treatment. In the last century some women literally went mad at this time of life and were admitted to lunatic asylums. ‘A cup of tea, a Bex and a good lie down’ (a well known ad on Australian radio in the 1940s and 50s) was often all that was available for our mothers or grandmothers. But to merely cover up the symptoms is no longer adequate, and it was then positively dangerous (long-term use of the phenacetin in Bex tablets caused kidney failure, and these were the days before dialysis and kidney transplants). In the next decade many women were prescribed and became addicted to Valium or Serepax. This became the crutch that they could not throw away.

So if it is not my hormones, is it ME? What is happening to me? What can I do? Most of us now believe that what goes on inside our mind will eventually show up in our body. We are familiar with phrases like ‘It makes me sick just thinking about it’; ‘Her resentment was eating away at her’; ‘He’s a real pain in the neck’. We know instinctively that a healthy mind is necessary for a healthy body. Medical research confirms this. But as well as physical and hormonal changes there are emotional responses that can threaten to overwhelm us. If these are understood and dealt with we need not feel helpless. Later we will look at attitudes and perception, about how we see others and ourselves, and examine our behaviour and the choices we make.

We seem to be more aware these days that we are all connected; we are always in relationship to someone or something. This is particularly true for midlife women with children growing up and parents ageing and dying. The choices we make about our own wellbeing will therefore impact on the lives of others as well as on our own lives.

We all want happiness, health and peace of mind, but many women experience instead suffering, loneliness and separation. In underdeveloped countries where women face terror and destruction they undergo constrictions and mutilations that we hear of, but can only barely imagine. Equally there are constrictions and mutilations of the psyche in our ‘more enlightened’ society which prevent women from enjoying freedom and happiness. The stories in this book may help some women to take away the emotional ‘shield’ that hides them. All of us want to be happy, and most of us long for inner peace, particularly at midlife when hormonal and emotional changes may bring turmoil.

The following chapters include information and tools that can improve physical and emotional wellbeing for women in midlife as well as stories of women and their journeys to find peace. In our everyday lives and as women in relationships we need ways to help us achieve health and happiness. The theme of practical forgiveness threads its way through the pages that follow, because this is a rich resource for personal liberation, if only we have the willingness to put it into practice.

Part 1

Is it me or my hormones?


Hormones –

can we do without them?

If the changes we fear be thus irresistible

What remains but to acquiesce in silence?

Samuel Johnson (1709–1784)

Can we do without hormones? Is menopause an estrogen-deficiency disease, as some doctors claim, requiring hormone replacement therapy for every woman, or is it a perfectly natural transition like menarche (the beginning of menstruation), perhaps implying that no woman requires HRT?

The word ‘hormone’ is derived from a Greek word meaning ‘setting in motion’ or ‘messenger’. Sex hormones are steroid molecules produced in special glands, mainly the adrenals, ovaries and testes. These hormones are secreted into the bloodstream and travel in the bloodstream to those organs which are able to use them. They are taken up, in certain tissues, by means of receptors on the surface of cells. So hormones affect only those cells that can take them up. This is different from many other types of medication in common usage, for example, synthetic drugs used to treat high blood pressure, which are less discriminate in their action and may therefore have significant side effects as they act generally in the body not just in the cells which have specific receptors.

Hormones have specific actions in specific tissues and thus set in motion specific responses, such as the growth and division of cells by estrogens and production of nourishing secretions by progesterone.

In this book the word ‘hormones’ is used to refer to the female sex hormones unless otherwise indicated. Note that when the word ‘steroid’ is used it does not mean ‘cortico-steroid’, which is the name for powerful hormones produced by the adrenal cortex. Cortico-steroids have acquired a reputation for being strong hormones with significant side effects. They can be lifesaving but must be used with care. The pituitary gland, situated under the front part of the brain, has been called ‘the conductor of the endocrine or hormone orchestra’, since it secretes hormones to stimulate the various hormone-producing glands.

In the normal menstrual cycle, FSH (Follicle Stimulating Hormone) and estrogen levels start rising as menstruation begins, so we always call the first day of a period the first day of a new cycle. The FSH stimulates several follicles in the ovary to produce estrogens, estradiol being the main estrogen produced. Usually only one follicle becomes the major producer of hormones; the others just fade away. When estrogen levels reach a certain peak, the LH (luteinising hormone) is released from the pituitary gland to stimulate ovulation. If this happens, the egg is released (ovulation) and travels across to the end of the fallopian tube to begin its hopeful journey down to meet the sperm (there are millions of them with, usually, only one winner). Progesterone as well as estrogen is then produced in the follicle and released into the bloodstream to make the body ready for pregnancy. The word ‘pro-gest-erone’ literally means ‘for pregnancy hormone’. If there is no fertilisation, hormone levels drop, the lining of the uterus (endometrium) breaks down, menstruation begins and thus a new cycle starts.

At menopause, when all the eggs (ova) are gone, both FSH and LH rise to high levels and remain high because so little estrogen is produced that there is no feedback to the pituitary to switch off these stimulating hormones. Menstruation ceases because there is now little stimulation of the endometrium and thus no tissue to bleed.

Measurement of estradiol and FSH can therefore help to diagnose menopause. Estradiol will be low and FSH high.

Diagrams of a normal menstrual cycle and the hormone changes in the perimenopausal ‘cycle’ are included below. The latter is sometimes anything but a cycle, as bleeding may be heavy or light and the period may come sooner or later than the normal 28-day cycle.


The first day of menstruation is day 1 of a cycle.

In response to FSH (follicle stimulating hormone) from the pituitary gland, estrogens are produced in the follicle of the ovary and estrogen levels rise steadily to mid-cycle, day 14. There is then a small drop in estrogens, they rise again for a few days, and then fall from about day 25. At day 28 levels are below a threshold and the next period starts.

Of course, if conception has occurred, the estrogens continue to rise and pregnancy then switches off the periods for at least nine months.


The progesterone level is low for the first half of the cycle. If ovulation occurs, in response to the LH (luteinising hormone) from the pituitary, then the follicle sheds its egg (ovulation) and the remaining follicle bed secretes progesterone. The level of progesterone rises and then starts to fall about day 25 – when estrogen also falls.

The withdrawal of both the hormones induces the withdrawal bleed that we call the menstrual period, or menstruation.

If estrogen levels are high, symptoms such as breast soreness and mood swings may occur. If estrogen levels are low, symptoms of estrogen deficiency such as hot flushes, tiredness and sleep changes may occur, often intermittently.

As show in the figure above, the estrogen levels vary widely and the progesterone level is low for the whole time, as ovulation has not occurred. The lack of progesterone does not, by itself, cause any particular symptoms. Women are at the mercy of their estrogens!

Does this mean that hormones are produced only for reproduction, so that women at the end of reproduction are left high and dry without hormones? This seems rather unfair. Has nature got it wrong? And, even more importantly, can we do without hormones? This raises the question we asked at the beginning of the chapter: is menopause an estrogen-deficiency disease or is it a perfectly natural transition?

There is considerable variation in the manifestations of menopause in individual women. The ideal management of the menopausal woman is by individual assessment, which should take into account the benefits and risks of treatment or no treatment. Women have said to us that they are afraid of HRT because it is ‘chemical and can cause damage to tissues’. In fact, the hormones used these days, although produced in a laboratory, are biologically the same as the estrogens that women themselves produce, so they are not ‘chemicals’ foreign to the body, unlike most of the pharmaceuticals that are used in modern medicine. Nevertheless, it seems wise to keep doses as low as possible to avoid side effects. Professor Susan Davis from the Jean Hailes Centre in Melbourne recently made a plea in a doctor’s magazine to ‘Stop bombarding women with HRT’. She suggests that low doses of estradiol administered via a transdermal patch – one which is applied to the skin – is preferable to high doses given orally.

When estrogens are taken by the mouth, they are absorbed by the gut and then processed by the liver. The liver produces a substance called sex-hormone-binding globulin (SHBG), which binds the hormone for transport through the bloodstream. It binds both estrogen and the male hormone testosterone, so high doses of estrogen will push up the SHBG and bind the testosterone that the woman is still producing, thus reducing its effectiveness. It is useful to measure testosterone levels in postmenopausal women, particularly if they complain of low libido and lack of energy despite adequate estrogen replacement. I am not saying that all women or even many women need testosterone replacement, just that it is worth considering if libido is low and testosterone levels are low. This will be discussed more fully in Chapter 21. High doses of estrogen can cause overactivity of cells: for example, soreness and lumpiness in the breasts may result in some women and we have always to balance the dosage of HRT against possible side effects. My colleague, Dr Barry Wren, says: ‘But hormones don’t harm tissues; they simply increase the activity of cell function, which is growth and division. So in this sense they have not been proven to cause cancer, but will certainly make estrogen-sensitive cancers grow more rapidly.’

Many women can live happy, healthy lives without hormones.

Many women can live happy, healthy lives without hormones. Some women have only a gradual loss of hormones at menopause and no symptoms of their deficiency; it may be that these women produce enough estrogen in their adrenal glands to tide them over. The estrogen referred to here is called estrone (which is the hormone used in some HRT, e.g. Premarin and Ogen). Patches, implants and some tablets contain estradiol, the main estrogen produced in the ovaries during reproductive life. Thus estrone and estradiol are natural in the real sense.

Some women cope with mild to moderate symptoms easily or prefer not to seek help. Others may avoid hormone therapy despite experiencing symptoms of menopause because of personal factors such as a high risk of clotting or recent breast cancer. Women need sufficient information to help them make the choice whether or not to take hormone replacements.

Some women prefer to use what they call ‘natural’ products such as soy derivatives and certain herbs (e.g. black cohosh, ginseng, etc.). Although some of these are called plant estrogens, they are not the same as women’s own estrogens and thus are not very effective in relieving true estrogen-deficiency symptoms. They are often more expensive than HRT and unfortunately have not undergone rigorous scientific trials.


• Menopause is a natural event.

• Some women pass through it uneventfully; some women have symptoms due to hormone deficiency and need hormone treatment.

• Women need individual assessment to decide the benefits and risks of hormone therapy.

• Natural products (usually not real hormones) are available but have not undergone scientific trials.


What else is happening

in midlife?

Nothing is certain but uncertainty.

Latin proverb

Is everything that happens during midlife and menopause merely a reflection of our hormonal state? What else is happening? A lot may be happening, often too much for a woman (or those around her) to cope with. Despite labour-saving devices, many women are busier than ever before and certainly busier than their mothers were. Family problems are different, with relationships and marriages breaking down, and children on drugs or jobless.

Gail’s story gives us an idea of the types of issues that may be confronting the menopausal or postmenopausal woman.

It’s all happening!

Gail is 60. She had a relatively late menopause. Her periods ceased at age 54 and she had classic symptoms for which she was given HRT, with good results. She stopped this after three years because she felt she did not need it and she was also having breast soreness and gaining weight. She is now tired and is not sleeping well. She has some palpitations and is not coping with day-to-day events.

Her doctor suggested that she go back on HRT, but she is concerned about the risk of breast cancer, particularly because her mother had this type of cancer. This occurred at a late age and her mother died of heart failure, not breast cancer. Though this may not increase Gail’s own risk, it certainly makes her more wary of taking HRT.

Gail is clinically depressed. It is mild, but she has the classic symptom of early morning wakening. She described herself this way: ‘I don’t feel hopeless, but I feel copeless!’ All her life she has coped well even though there has been much to test her. When we went through her family situation there was enough there to make anyone want to give up! Her eldest son is an alcoholic and has left his marriage and two small children. Her daughter has been on drugs. Her youngest son has had a life-threatening cancer. Her husband was more and more absent from home, supposedly on business, and then came home and was behaving so oddly that she had to tackle him about it. He finally admitted that he was involved with another woman and that he wanted a divorce so that he could remarry. Within the next six months her sister divorced her husband after 30 years of marriage, their father died and her younger sister, aged 50, died of cancer.

The question ‘What else is happening?’ is very relevant here. This is a situation where the loss of hormones is no longer causing physical symptoms. Gail went through the stage of hot flushes and these were relieved by HRT at that time. Her present depression is caused mainly by outside circumstances. This is called exogenous, or outside, depression, as opposed to endogenous depression, which comes from something within and may be biochemical. Gail’s is an emotional rather than a physical problem. She does not need HRT, or antidepressants, but she does need to be listened to and have her grief and loss validated. She also needs to be shown a way to change her attitude. It is possible to choose what happens rather than feel that things just ‘happen’ to us. At times like this women need to support each other: close friendships can be lifesaving and support groups can be helpful.

Medicalisation of menopause is a stumbling block for many women, particularly with the adverse and contradictory publicity given to recent research data on HRT. However, we can’t afford to use this as a reason to go back into the ‘dark ages’ and pretend nothing is happening.

As discussed in many of the following chapters, there are so many things happening to women at this stage and they all seem to be colliding in the corridor called ‘midlife’. The aches, pains and limitations of the ageing body are quite natural, and while these can certainly be improved with exercise, diet, attitude and lifestyle, somewhere in the midst of this comes the realisation that life is very short and our time here is limited. If ‘this is as good as it gets’ we had better find constructive ways to make the most of it.

Take charge of your choices

Whether we feel fear-based emotions or those that make us peaceful inside is really a matter of choice. Most of us probably don’t realise the extent to which we are constantly making choices minute by minute every day. As a woman in midlife you may have to face a number of critical life events and, as a result, you will have choices to make in how you respond:

• Your parents may become very frail and need your emotional and physical help.

• You will probably go through the death of your parents.

• You may experience the death of someone you love.

• You or your husband, or both, may
