The short answer: Perimenopause is the stretch of years before menopause when your hormones rise and fall unpredictably. For many Indian women it begins in the early 40s, sometimes the late 30s. Periods may come closer together or further apart, and turn heavier or lighter. Hot flushes, poor sleep, mood changes and vaginal dryness are common. Treatment and simple changes help a lot. Get very heavy bleeding, bleeding between periods, or any bleeding a year after your last period checked by a doctor.
What is perimenopause?
Perimenopause means "around menopause". It is the transition phase when your ovaries gradually make less oestrogen and progesterone, the two hormones that run your monthly cycle. The fall is not smooth. Hormone levels can swing high one month and low the next, which is why symptoms come and go.
During this time you ovulate (release an egg) less regularly. Some cycles have no ovulation at all. Because ovulation is what sets the timing and heaviness of a period, irregular ovulation is behind most of the period changes you notice.
Perimenopause ends at menopause. The NHS says symptoms of menopause and perimenopause usually last for 7 to 9 years, sometimes longer, and they can change over that time.
Perimenopause, menopause and postmenopause: the difference
These three words are often mixed up. Here is how they fit together.
| Stage | What it means | What happens to periods |
|---|---|---|
| Perimenopause | The years before your final period, when hormone levels fluctuate | Periods change: closer together, further apart, heavier, lighter or skipped |
| Menopause | A single point in time: 12 months in a row with no period | Your final period is only known in hindsight, a year later |
| Postmenopause | Every year after menopause | No periods. Any bleeding at all needs a doctor's check |
So if you have skipped three or four months and then bled again, you are still in perimenopause, not menopause. The 12-month count starts again from that bleed.
When does perimenopause start in Indian women?
There is no fixed age, but Indian women tend to reach menopause earlier than women in the West. A pan-India survey by the Indian Menopause Society, published in the Journal of Mid-Life Health in 2016, found the average age of menopause among Indian women was 46.2 years, compared with about 51 in Western countries. The NHS gives 51 as the average age in the UK.
If menopause comes around 46 on average, perimenopause changes often start in the early 40s, and some women notice them in their late 30s. Many Indian women are handling hot flushes and unpredictable periods while raising school-age children, working, or caring for older parents.
The same survey found that the age of menopause varied with factors such as where women lived and their circumstances, so your own timing may be earlier or later than average. Your mother's or elder sister's experience can give you a rough idea, but it is not a rule.
How your periods may change
Changes to your periods are often one of the first signs. The NHS and HSE Ireland both describe a wide range of patterns, and you may move between them over the years.
Timing
- Closer together: early on, cycles often shorten, so periods may arrive every two or three weeks.
- Further apart: later, you may skip a month, or several months, and then have a period again.
- Unpredictable: a 24-day cycle followed by a 50-day one is common.
Flow and length
- Heavier: when you don't ovulate, the womb lining can build up for longer and then shed heavily, sometimes with clots.
- Lighter: some cycles are short and light, with mostly pink or brown blood.
- Longer or shorter: a period that used to last five days may run to eight, or finish in two.
- Spotting: light bleeding between periods becomes more common, though it still deserves a check.
Some women keep fairly regular periods right up until they stop. Others have years of chaos. Both are normal versions of perimenopause. If your cycles are all over the place, our guide to irregular periods explains the other causes a doctor will think about.
Other symptoms of perimenopause
Hormones affect far more than your womb, so the list of possible symptoms is long. You are unlikely to have all of them.
| Body | Mind and mood |
|---|---|
| Hot flushes: sudden heat in the face, neck and chest, sometimes with sweating and a red face | Mood swings and irritability, often made worse by poor sleep |
| Night sweats that soak your nightie or sheets | Low mood or anxiety, sometimes for the first time in your life |
| Trouble falling or staying asleep | Poor memory and concentration, often called brain fog |
| Vaginal dryness, itching or pain during sex | Lower confidence or self-esteem |
| Needing to pee more often, or more urine infections | Lower sex drive |
| Leaking a little urine when you cough, sneeze or lift | Feeling overwhelmed by things you used to manage easily |
| Headaches or worse migraines, joint and muscle aches | Feeling less like yourself |
| Weight gain around the tummy, thinning hair, dry itchy skin | Stress that seems out of proportion |
The NHS also lists palpitations (a heartbeat that feels fast or more noticeable) and gum or mouth problems. Over the longer term, falling oestrogen speeds up bone loss, which raises the risk of osteoporosis, or weak bones.
Many women brush these off as "age" or "tension". They are real, and they can be treated.
Can you still get pregnant during perimenopause?
Yes. Fertility falls, but you still ovulate some months, and you can't tell which ones.
The NHS advises using contraception until 2 years after your last period if you are 40 to 49, or 1 year after your last period if you are 50 or over. Hormonal contraception can also mask perimenopause: the combined pill gives you a monthly bleed regardless, while the hormonal coil, implant or injection can stop periods altogether. Your doctor can help you work out when it is safe to stop.
If your period is late and you've had sex without contraception, do a home pregnancy test before assuming it's perimenopause. Our guide to a late period when you're not pregnant covers the other reasons.
When to see a doctor or get urgent help
See a doctor if
- Your periods are much heavier than before, you need to change protection every one to two hours, or you pass clots larger than about 2.5 cm
- Your periods last more than 7 days
- You bleed between periods or after sex
- Your periods come every two weeks or so for several months
- You feel tired, breathless or dizzy, which can be a sign of anaemia from heavy bleeding
- You have palpitations
- Symptoms are affecting your sleep, work, relationships or mood
- You have any bleeding after 12 months without a period, even a small amount of pink or brown spotting
Heavy or irregular bleeding in your 40s is usually hormonal. Even so, a doctor will want to rule out fibroids (non-cancerous growths in the womb), polyps, thyroid problems and, less commonly, changes in the womb lining. Bleeding after menopause is not usually serious, but it always needs checking. Our guide to how much bleeding is too much has a practical way to measure your flow.
Get urgent help if
Call 112 or 108, or go to the nearest hospital emergency department, if you are soaking through a pad or period panty every hour for several hours, you feel faint, very dizzy or confused, you have chest pain or severe breathlessness, or you have heavy bleeding with severe tummy pain and could be pregnant.
If low mood is making it hard to cope, or you are having thoughts of harming yourself, you can call Tele-MANAS, the government's free mental health helpline, on 14416 at any time.
What the doctor may do
Perimenopause is usually diagnosed from your age and symptoms. Blood tests for hormones are often not needed in women over 45, because levels swing so much from day to day that one result says little.
Depending on your symptoms, your gynaecologist may suggest:
- A haemoglobin test to check for anaemia, and a thyroid test, since thyroid problems can mimic perimenopause
- A pelvic ultrasound if bleeding is heavy, long or irregular, to look for fibroids or polyps
- Cervical screening (a Pap smear or HPV test) if you are due
- Sampling of the womb lining in some cases of unusual bleeding
- Questions about your bones, heart health, blood pressure and family history
Write down your symptoms and the dates of your periods for two or three months before the appointment. It makes the conversation faster and more useful.
Treatments and self-care that help
Hormone replacement therapy (HRT)
HRT replaces the oestrogen your body is making less of. It comes as tablets, patches, gels or sprays. If you still have your womb, you also need a progestogen to protect the womb lining, which can be a tablet, a combined patch or a hormonal coil. HRT can ease hot flushes, night sweats, mood swings, vaginal dryness and sleep problems, and may help protect your bones. Your doctor may suggest it after talking through your health history and any risks.
Treatments for specific symptoms
- Vaginal dryness: vaginal oestrogen creams or pessaries on prescription, or over-the-counter vaginal moisturisers and water-based lubricants. A pharmacist can advise you privately.
- Hot flushes, if HRT isn't suitable: your doctor may suggest non-hormonal medicines.
- Low mood and anxiety: cognitive behavioural therapy (CBT), a talking therapy, helps with mood, sleep and even hot flushes. Antidepressants may be offered for depression.
- Heavy periods: options include a hormonal coil, tranexamic acid tablets, or treatment for fibroids if they are the cause.
Be careful with herbal supplements sold for menopause. The NHS says there is very little evidence on how well remedies like black cohosh and red clover work, and some interact with other medicines. Check with your doctor first.
Everyday changes that make a difference
- Build your bones: eat calcium-rich foods every day, such as milk, curd, paneer, ragi, sesame (til) and green leafy vegetables. Get some daily sunlight, and ask your doctor whether you need vitamin D.
- Move with weight: brisk walking, climbing stairs, yoga and simple strength exercises with water bottles or resistance bands all help bones and mood.
- Protein at every meal: dal, chana, rajma, eggs, fish, paneer or curd help you keep muscle as hormones fall.
- Cool down at night: a fan, light cotton nightwear, a cool shower before bed and a glass of water by the bed help with night sweats.
- Notice your triggers: spicy food, very hot chai or coffee, alcohol and smoking can all set off hot flushes for some women.
- Pelvic floor exercises: squeezing and lifting the muscles you would use to stop a wee, ten times, three times a day, helps with small leaks.
- Talk about it: friends, sisters and colleagues going through the same thing can be a huge relief.
Getting through unpredictable periods
For many women, the hardest part is not knowing when a period will come or how heavy it will be. A little planning takes away much of the stress.
- Heavy days and nights: a high waist period panty gives more front-to-back and tummy coverage, and period boy shorts have a longer leg and a wider absorbent zone, which suits nights. On very heavy days you can wear a pad as well.
- Spotting days: a panty liner is often enough.
- Carry a spare: keep a small pouch with a liner, a spare pair of underwear and wipes in your handbag, office drawer or car.
- Track your bleeding: note the start and end date of each period and how many times a day you change protection. A simple note on your phone works.
If your periods have become hard to predict, our guide to calculating your next period date shows how to work out a likely window from your recent cycles.
Frequently asked questions
At what age does perimenopause start? Most often in the early to mid-40s, but some women notice changes from their late 30s. Indian women reach menopause at about 46 on average, earlier than in the West.
How long does perimenopause last? It varies a lot. The NHS says symptoms usually last 7 to 9 years, sometimes longer, and they can change over that time.
Can perimenopause cause very heavy periods? Yes. When you don't ovulate, the womb lining can build up more than usual and shed heavily. If you're changing protection every one or two hours, see a doctor.
Is it menopause if I skip a few periods? Not yet. Menopause is confirmed only after 12 months in a row without a period.
Can I get pregnant during perimenopause? Yes. Keep using contraception until 2 years after your last period if you're under 50, or 1 year if you're 50 or over.
Do I need a blood test to confirm perimenopause? Usually not if you are over 45 with typical symptoms. Your doctor may still test for anaemia or thyroid problems.
