Perimenopause is the stage leading up to menopause, when your hormone levels begin to change and your body transitions towards the end of your reproductive years. It often starts in your 40s, but can begin earlier for some women.

During perimenopause, the levels hormones produced by your ovaries (oestrogen and progesterone) start to change. This causes your periods to change (become irregular, heavier or lighter), and many women start experiencing perimenopausal symptoms.

According to the Australian Government Health Department perimenopause can last between 2 and 10 years, with an average around 4 to 6 years.

Yes. Although fertility declines during perimenopause, there is a chance you can still get pregnant until menopause has occurred. If you do not want to become pregnant, contraception is generally recommended until you have gone 12 consecutive months without a menstrual period.

According to the World Health Organization, many women may experience menopause between the ages of 45 and 55 years old. This is a natural process of ageing.

Every woman's experience is different, but common symptoms can include hot flushes, night sweats, sleep disturbances, vaginal dryness, mood changes and changes in menstrual patterns.

You will know you have reached menopause when you haven't had a period for 12 months in a row (with no other medical reason).

Supporting your health through perimenopause, menopause and postmenopause involves focusing on healthy lifestyle habits, such as regular physical activity, a balanced diet, good quality sleep and managing stress. There are also hormonal and non-hormonal methods that may help manage symptoms. Speak with a healthcare professional to determine the most appropriate options for you.
