Can perimenopause cause heavy periods?

Heavy periods are a common symptom during the perimenopause stage.

Some women find that their periods become more difficult to manage, with increased bleeding or longer-lasting periods.

What do heavy periods feel like in perimenopause?

Heavy periods may involve soaking through pads or tampons more quickly than usual, passing clots or needing to change protection during the night. This can affect daily activities and sleep.

Why does perimenopause cause heavy bleeding?

During perimenopause, higher or fluctuating oestrogen levels can cause the lining of the uterus to build up more than usual. When it sheds, this can lead to heavier bleeding.

Heavy and prolonged periods in perimenopause

Heavy periods are sometimes linked with periods that last longer than normal. Bleeding may continue for several days beyond your usual pattern.

How heavy periods affect daily life in perimenopause

Heavy bleeding can lead to tiredness, inconvenience and concern. Some women may also develop low iron levels if heavy periods continue over time.

When to see a doctor

Heavy periods should be assessed by a doctor if you experience:

bleeding that soaks through protection every hour
periods lasting longer than usual
large clots or flooding
symptoms of fatigue or low energy
