"Heavy periods" means that a female loses a lot of blood during menstrual periods. This can happen because:
- Bleeding is very heavy during periods.
- Periods last longer than normal.
Heavy periods can lead to anemia (too few red blood cells). Someone with anemia may feel tired or dizzy, have a headache, and look pale.
If needed, there are ways to treat heavy periods. Help your child follow these instructions.

What causes heavy periods? Some of the things that cause heavy periods are:
- Changing hormone levels in the first few years after someone starts getting their period
- Hormonal problems
- Having extra body weight
- Medical conditions that cause easy bleeding
- Fibroids or other growths in the uterus
How are heavy periods treated? Treatment for heavy periods depends on what's causing it. It may include:
- Waiting to see if periods get lighter (in someone who has started getting periods recently)
- A recommendation to lose weight through changes in diet and increasing exercise
- Medicines that can balance hormones, such as the birth control pill ("the Pill"); also a birth control shot, a birth control implant, or an IUD
- Iron supplements for anemia
