Perimenopause: Early Signs and Symptom Management
Most women associate the menopause with a sudden stop, but the reality is far gentler and much longer. Perimenopause, the transition leading up to your final period, can last from a few months to over a decade, often beginning in the early forties or even the late thirties. Many classic symptoms first appear during this stage, while periods are still happening. Recognising the early signs means you can get help sooner.
What perimenopause is
Perimenopause begins when your ovaries start producing less oestrogen and continues until a full year after your last period. Because hormone levels fluctuate rather than falling in a straight line, symptoms come and go in waves, which makes the stage confusing. You may feel very different from one month to the next. Perimenopause is not something that shows up on a routine test, so doctors usually diagnose it from your symptoms and pattern of periods.
Early signs to watch for
- Periods that become shorter, longer, lighter, heavier or further apart
- Hot flushes and night sweats, often the first symptom to arrive
- Sleep problems, including waking in the small hours and struggling to get back over
- Mood swings, irritability, anxiety or a lower mood than usual
- Brain fog, forgetfulness and difficulty concentrating
- A dip in libido and changes in how sex feels
Not everyone gets all of these, and the order they arrive in varies. Keeping a simple diary for a few months can reveal a pattern that is easy to miss when you are in the middle of it.
Tracking what is happening
A symptom diary is genuinely useful here. Note the date, whether you are bleeding, and score flushes, sleep, mood and energy on a simple scale. Take it to your GP, because it turns vague complaints into a clear picture and helps rule out conditions that mimic the perimenopause, such as an underactive thyroid or anaemia. If you are constantly exhausted, a blood test for iron levels is worth requesting.
Managing common symptoms
| Symptom | Typical pattern | What can help |
|---|---|---|
| Hot flushes | Come in waves, worse at night and with alcohol or caffeine | Layered clothing, a hand fan, cooling drinks, identifying triggers |
| Night sweats | Wake you soaked, wreck sleep | Cool bedroom, natural bedding, a cool cloth by the bed |
| Mood changes | Irritability and low mood around hormonal dips | Regular exercise, talking to someone, CBT-style approaches |
| Brain fog | Forgetfulness, losing words | Lists, routines, good sleep, gentle pacing |
| Vaginal dryness | Discomfort and soreness, often later in the stage | Moisturisers and lubricants, or vaginal oestrogen on prescription |
Always check with a pharmacist or GP before starting any treatment, including herbal products, since some interact with medicines.
When to see a GP
See a GP if symptoms are affecting your sleep, mood, work or relationships, or if your periods are very heavy. There is no need to wait until periods stop. A doctor can confirm the likely diagnosis, offer treatment such as HRT, and check that nothing else is going on. You can also read what to expect from the menopause itself so the whole picture is clear.
The foundations that help
Whatever your symptoms, three things help: regular physical activity, which cools flushes and lifts mood; good sleep habits, because tiredness magnifies everything; and cutting back on alcohol and caffeine, both of which trigger flushes. If sleep is your biggest problem, the article on menopause and sleep goes into it in depth.
Perimenopause is a transition, not a medical failure, and it is more common to feel overwhelmed than people admit. Track your symptoms, ask for help early and lean on the treatments available.
