How to use this health conditions guide
Each condition page explains what it is, its causes and symptoms, how it is diagnosed and treated, and which specialist usually manages it. Use it to understand a diagnosis or prepare questions for your doctor, then find specialists, hospitals and lab tests near you. The pages are general information and cannot replace an examination by a qualified doctor.
Getting care for a health condition
Most long-term conditions are managed by a specialist together with a general physician. Keep a record of your diagnosis, test results and medicines, go for the follow-up tests your doctor advises, and ask what warning signs should prompt an earlier visit. For your condition, bring previous reports and a list of current medicines to every appointment so changes can be tracked over time.
Do not stop or change prescribed medicines without talking to your doctor, even if you feel better.
Finding care near you
Open any health condition page and choose your state, city or area to see matching specialists, hospitals and labs there. You can also browse doctors, hospitals and lab tests directly, or use the symptom-to-specialist guide if you are unsure whom to see. In an emergency, call 108 or 112.
This page is general information and not medical advice.
