Julie* used to have heavy periods but around the age of 44/45, she noticed a drastic decrease in her menstrual flow, as it became lighter over time. Now aged, 48, she has a list of other symptoms too, including hair loss, insomnia, hot flashes, headaches and weight gain. 

Last year, when Natalie* was 46, she started getting hot flashes and felt prickly and hot for no reason. These symptoms now appear more often. 

Sonia*, 49, has always had very regular periods. Since mid-2020, however, her periods have become unpredictable, skipping a month at times, then six or seven months of regular cycles, before becoming irregular for a few months again. Her periods are also shorter now, lasting around three days, when they were at least five days before. And, in the last six months, she has had interrupted sleep too.

What all these women are going through is perimenopause. We know that menopause is when our periods end but while there has been a lot of mention of the M-word, what happens before that might not be as well-known. The fact is, our periods don't just come to an abrupt end. It's not like we wake up one day and realise we've hit menopause. The phase leading up to it is known as perimenopause and it can last several years. 

Menopause takes place when a woman has no menstrual period for 12 consecutive months. In Singapore, the average age of menopause is 49 years, two years younger than in Western societies. However, it can happen anytime between the ages of 45 to 55. 

Perimenopause lasts four to six years on average but it can be as short as one year or as long as 10. Signs of perimenopause usually appear in our mid to late 40s. Once a woman reaches menopause, she is then post-menopausal. The bad news is, symptoms experienced during perimenopause could still continue for a few years after your periods have stopped.

Every woman goes through menopause but not all women will experience the symptoms associated with perimenopause. We get these symptoms because of the change in hormone levels in our body, especially oestrogen and progesterone.

These are some of the more common perimenopausal symptoms:

hot flushes
night sweats
dry skin
body aches
sore breasts
loss of libido
vaginal dryness
difficulty sleeping
mood changes
memory issues

Associate Professor Ang Seng Bin, Head and Senior Consultant, Menopause Unit and Senior Consultant, Family Medicine Service, KK Women’s and Children’s Hospital, says that the most common symptom involves your cycle.

“The most common symptom of perimenopause is changes to the menses; this may lead to shortened or lengthened cycles,” he explains. “This means if one used to have regular 28-day cycles, one may experience shortened cycles like 21 days or lengthened cycles like 60 days.

“Hot flushes, which is a transient sensation of extreme heat, may also occur in some women. When hot flushes occur at night, it can also cause disturbances to sleep and affect the woman's quality of life,” he adds.

Associate Professor Ang reveals that, for Asian women, other than the usual hot flushes, what appears to be common is body aches and joint pains. Unfortunately, there's nothing in our personal or health history – such as whether or not you have children, or what menopause was like for your mother – that could tell us what perimenopause will be like for us, he adds.

The doctor says that while most symptoms are usually tolerable, “there are women who find them extremely troublesome”. Such women will benefit from consulting a doctor for a proper evaluation to exclude other medical conditions that can mimic perimenopausal symptoms such as thyroid disease.

He also suggests adopting lifestyle changes first, like getting regular sleep hours with good sleep hygiene, as well as maintaining a healthy body mass index of 23 and below through healthy eating and regular exercise.

“For those who have tried the above but are still having issues, or those who start menopause at age 45 years and below, they may benefit from menopausal hormone therapy if there are no medical reasons to avoid it,” he adds.

Associate Professor Ang also cautions against taking any over-the-counter or home remedies as there haven't been any good long-term studies for them.

“Placebo effect is high, at close to 50 per cent,” he says. “Women should consult their doctor before they take over-the-counter medications. If the remedies work, they should not exceed the consumption for more than six months as there could be potential long-term risks which have not been evaluated.”

Julie said that perimenopause is something new to her as none of her older female relatives have mentioned it to her. And what she has experienced so far is making her a bit nervous about what comes next.

“Of course I expected menopause to be a gradual change, not just your period stopping overnight, but now with these symptoms, I'm a bit more worried about menopause. Like, it's so uncomfortable now, will it be worse?” she shares.

She consulted her gynae who said it's all part and parcel of menopause and urged her to exercise more to get better sleep and keep her weight down. No hormone therapy was discussed, as Julie is not open to it yet. She does take the occasional Panadol for headaches and melatonin for insomnia, plus birds nest soup as she was told it would help ease her symptoms.

Natalie acknowledges that she also didn't know much about perimenopause before it happened to her nor does she know a lot more about it now. She doesn't think that “knowing much would solve any of my symptoms so just go with the flow, or lack of”. While she doesn't have any mental or emotional issues about going through it, she admits “it's the physical aspect that is very challenging”.

She has been taking evening primrose oil, which she understands is meant to relieve her symptoms but hasn't felt much of a difference so far. However, she does wonder if her symptoms would be worse if she wasn't taking it.

Sonia has an older sister who went through menopause a few years ago so had some prior knowledge of it. “I haven't had hot flashes even though my sister had them,” she tells us. “And I've got used to not worrying about when my period will come as it's so unpredictable now. But what does annoy me is that I keep waking up most nights and not sleeping through the night really affects my day. I also get a bit stressed lying in bed at 4am wondering when I'm going to get back to sleep.”
