Heavy Periods: How to Care for Your Child

"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.

Care Instructions

  • Be sure your child follows the health care provider's recommendations for taking any medicines.
  • Help your child to:
    • Track periods on a calendar or a smartphone app.
    • Eat a healthy, well-balanced diet.
    • Follow any changes in diet or exercise that the health care provider recommends.
  • Someone with heavy periods can still get pregnant if they have sex. Talk to your child about using condoms to protect against pregnancy and sexually transmitted infections (STIs, also called sexually transmitted diseases or STDs).
  • Follow up as instructed by your health care provider.
