Perimenopause Heavy Periods: Why Bleeding Gets Worse
Heavy periods in perimenopause happen because fluctuating hormones cause the uterine lining to build up more before shedding. Flooding, clots, and prolonged bleeding are common. While often hormonal, very heavy bleeding should be evaluated to rule out fibroids or other causes.
When to be concerned
Some heavy bleeding is expected, but certain patterns warrant evaluation.
- Soaking through protection every hour for several hours.
- Periods lasting more than seven days.
- Passing large clots (bigger than a quarter).
- Bleeding between periods or after sex.
