Which doctor treats this

• Start with your primary care provider (family doctor or internist).
• They may send you to an endocrinologist (hormone doctor).

Living with it

• Take thyroid pills the same way every day, often on an empty stomach.
• Get blood tests as advised.
• Long-term illness can affect mood. Tell your doctor if you feel down or anxious.

Support groups and helplines

• American Thyroid Association: Patient guides and support group finder.

Back to school, work, or sports

• Most people can keep working or going to school.
• 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

• After pregnancy: About 1 in 20 new mothers.

Pregnancy and breastfeeding

• If you're pregnant or planning to be, tell your prenatal provider about this condition.
• This condition needs closer checkups during pregnancy. Plan ahead with your doctor.
• 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

• Go to visits when you can and take notes.
• Keep a list of medicines, allergies, and doctors in one place.
• Learn the warning signs that need fast care.
• Take breaks and ask for help. Caregivers need care too.

Outlook

Most recover within a year.
