Most women will experience menopausal symptoms. Some of these can be quite severe and have a significant impact on your everyday activities.
Common symptoms include:
Menopausal symptoms can begin months or even years before your periods stop and last around 4 years after your last period, although some women experience them for much longer.
It's worth talking to a GP if you have menopausal symptoms that are troubling you or if you're experiencing symptoms of the menopause before 45 years of age.
They can usually confirm whether you're menopausal based on your symptoms, but a blood test to measure your hormone levels may be carried out if you're under 45.
Your GP can offer treatments and suggest lifestyle changes if you have severe menopausal symptoms that interfere with your day-to-day life.
Your GP may refer you to a menopause specialist if your symptoms do not improve after trying treatment or if you're unable to take HRT.
The menopause is caused by a change in the balance of the body's sex hormones, which occurs as you get older.
It happens when your ovaries stop producing as much of the hormone oestrogen and no longer release an egg each month.
Premature or early menopause can occur at any age, and in many cases there's no clear cause.
Sometimes it's caused by a treatment such as surgery to remove the ovaries (oophorectomy), some breast cancer treatments, chemotherapy or radiotherapy, or it can be brought on by an underlying condition, such as Down's syndrome or Addison's disease.
