Perimenopause: symptoms, how long it lasts and treatment options
Perimenopause is the transition before the menopause, when hormone levels change and periods become less predictable. Symptoms include irregular periods, hot flushes, night sweats, sleep problems, mood changes and vaginal dryness. They usually last 7 to 9 years, sometimes longer. You can still get pregnant. HRT, CBT and lifestyle changes can help.

What are the symptoms of perimenopause?
The NHS says perimenopause and menopause are different for everyone. You may get symptoms that have a big impact on relationships, social life, family life and work, or you may hardly have any symptoms at all. NHS inform says most women will experience menopausal symptoms, some few or none, and for some they can be quite severe.
The NHS says ethnic background can affect symptoms, how severe they are and how long they last. For example, it says women from a Black ethnic background are more likely to have hot flushes that are severe and continue longer.
| Symptom | What the NHS says |
|---|---|
| Changes to periods | Often one of the first signs. Periods may happen more or less often, and bleeding may get heavier or lighter, before stopping altogether |
| Hot flushes and night sweats | The face, neck and chest suddenly feel very hot or cold, which can cause sweating, palpitations, anxiety or dizziness, during the day or night, lasting several minutes |
| Sleep problems | Difficulty getting to or staying asleep, which can make you irritable, stressed and anxious |
| Mood changes, memory and brain fog | Mood swings, low mood or depression, and problems with memory or concentration |
| Weight gain | Common, often around the stomach and upper body |
| Vaginal problems | Dryness, burning, irritation or itching in and around the vagina, which can make sex painful |
| Urinary symptoms | More UTIs or symptoms that feel like a UTI, and sometimes urinary incontinence |
| Other | Palpitations, weakening bones, headaches and migraines worse than usual, muscle aches and joint pains, hair thinning, skin changes, reduced sex drive and mouth problems |
What is perimenopause?
NHS inform describes perimenopause as the time from the start of menopausal symptoms until after a woman has experienced her last period. Periods usually start to become less frequent over a few months or years before they stop altogether. They might be more irregular and become heavier or lighter, and for some women they can stop suddenly.
Menopause is when you have not had a period for 12 months, and after this you are postmenopausal. NHS inform explains that menopause happens when the ovaries stop producing as much oestrogen and no longer release an egg each month. Perimenopause and menopause are a natural part of life.
How long does perimenopause last?
The NHS says perimenopause ends when you reach menopause. Symptoms usually last for 7 to 9 years, sometimes longer, and during this time they can change. For example, you may get hot flushes and night sweats for a while, but they may improve and be replaced by other symptoms such as low mood and anxiety. You may also get symptoms that continue after menopause, such as joint pain and vaginal dryness.
At what age does perimenopause start?
NHS inform says perimenopause and menopause usually occur between 45 and 55 years of age as oestrogen levels drop, although it can start earlier, and that in the UK the average age to reach menopause is 51. It suggests looking at your family history, because it is likely to be a similar age to when your mother or older sisters started theirs.
NHS inform also says menopause can occur due to certain surgeries or cancer treatments, and that premature or early menopause can occur at any age and in many cases there is no clear cause. If you notice changes earlier than the usual age, speak to a GP.
How is perimenopause treated?
The NHS says if you have symptoms you can talk to a doctor, nurse or pharmacist about HRT and other options. The type of HRT you are offered depends on whether you still have periods or have had your womb removed.
NICE says that healthcare professionals should discuss treatment options with you, including the benefits and risks. NICE also says to consider menopause-specific cognitive behavioural therapy (CBT) for hot flushes and night sweats, in addition to HRT or for people who cannot or prefer not to take it.
| Option | What it helps and how it is taken |
|---|---|
| Oestrogen HRT | The main type of HRT, taken as tablets or used as patches, spray or gel |
| Progestogen | Needed if you take oestrogen and have not had a hysterectomy, to protect the womb; as tablets, a combined patch or the hormonal coil (IUS) |
| Vaginal oestrogen | Cream or pessary for vaginal dryness and soreness or urinary symptoms |
| Testosterone | Gel or cream may help low libido for some, and may be available from a menopause specialist |
| CBT | Can help with low mood, anxiety, sleep problems, hot flushes and night sweats |
| Clonidine or an antidepressant | May be suggested for hot flushes and night sweats if CBT does not help; antidepressants may be offered for low mood or anxiety |
| Herbal remedies | The NHS says there is very little evidence on how well red clover and black cohosh work or how safe they are, and some can cause serious side effects with other medicines |
Irregular periods, bleeding and contraception
The NHS says during perimenopause your periods may become irregular, lighter or heavier. If you take HRT you may have some irregular bleeding or spotting that should settle within 6 months, and you should talk to your GP if it continues after 6 months.
Contact a GP if you still have periods but your bleeding pattern has changed and you are bleeding more, not less, than before, or if you have not had a period for 12 months or more and have any vaginal bleeding. The NHS says postmenopausal bleeding is not usually serious but can be a sign of cancer, and should be checked even if it has only happened once.
The NHS says it is possible to get pregnant during perimenopause, so you still need contraception for 1 year after your final period if you are 50 or over, and for 2 years if you are aged 40 to 49. It says that hormonal contraception can make it harder to tell if you have reached perimenopause or menopause, and that the combined pill is not recommended from age 50 as the risks generally outweigh the benefits. HRT is not contraception.
Diet and lifestyle during perimenopause
The NHS says eating well, exercising and looking after your mental wellbeing can help with symptoms, and also helps you keep as well as possible in the future.
-
Try to eat a healthy, balanced diet.
-
Eat calcium-rich food such as milk, yoghurt and kale to keep bones healthy.
-
Exercise regularly, with a focus on weight-bearing exercise to help protect against weakening bones.
-
Get plenty of rest and keep to regular sleep routines.
-
Try relaxing activities such as yoga, tai chi or meditation.
-
Do not smoke, as this can make symptoms worse, and try not to drink more than the recommended alcohol limit.
-
Talk to a doctor before taking herbal supplements or complementary medicines.
-
For hot flushes, the NHS suggests lightweight clothing, a cool bedroom, a cool shower or cold drink, and avoiding triggers such as spicy food, caffeine, hot drinks, smoking and alcohol.
When to see a GP
The NHS says to contact your GP if you think you have symptoms of menopause or perimenopause and want to know your options, if you have symptoms such as a fast heartbeat (palpitations), if you still have periods but are bleeding more than before, or if you have not had a period for 12 months and have any vaginal bleeding. It says early advice can help reduce the effects on your health, relationships and work.
NICE says perimenopause can be identified without laboratory tests in otherwise healthy people aged 45 or over who have recently started vasomotor symptoms and changes in their menstrual cycle, and advises against using tests such as anti-Müllerian hormone or oestradiol to identify perimenopause in people aged 45 or over.
NHS and private pathways
On the NHS, menopause care usually starts with a GP, practice nurse or pharmacist, and the NHS notes that testosterone may be available on prescription from a menopause specialist. NICE guidance sets out what should be discussed and offered.
Some people choose a private menopause consultation for longer appointments or quicker access to specialist advice. Whichever route you take, it is reasonable to ask for the benefits and risks of each treatment to be explained, and to keep your GP informed of any prescription.
