Living with it
- Keep a simple diary of symptoms, triggers, and medicines to bring to visits.
- Bring a list of your medicines and questions to each visit.

- Get enough sleep and manage stress.
- Long-term illness can affect mood. Tell your doctor if you feel down or anxious.
Back to school, work, or sports

- Ask about changes that help, like extra breaks or a flexible schedule. Workers may be covered by the ADA. Students may get a 504 plan.
Children, pregnancy, and older adults
- Pregnancy: Pica is common and often linked to low iron.
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.
- Breastfeeding: Most medicines are fine, but ask. The NIH LactMed database lists what's known about each one.
For caregivers

- Keep a list of medicines, allergies, and doctors in one place.
