Living with it

Support groups and helplines

• Genetic and Rare Diseases Information Center (GARD): Free NIH information on rare diseases, including where to find experts and patient groups.
• National Organization for Rare Disorders (NORD): Patient groups, help finding care, and aid programs for rare diseases.

Children, pregnancy, and older adults

• Families: Prader-Willi Syndrome Association offers support.
• Babies: Weak muscles at birth.

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.
