Back to school, work, or sports
- Recovery time varies. Ask your care team when you can drive, lift, work, and exercise.
Children, pregnancy, and older adults
- People with past belly surgery: Higher risk.
Pregnancy and breastfeeding
- If you're pregnant or planning to be, tell your prenatal provider about this condition.
- Don't start or stop any medicine on your own. Some are safe in pregnancy and some need to be changed.
- Ask before taking any pain reliever. The FDA advises avoiding ibuprofen and naproxen after 20 weeks unless your doctor says to.

For caregivers
