MedlinePlus

MedlinePlus is a health-information resource from the U.S. National Library of Medicine. Its website provides understandable material about health topics, medicines, tests, and other subjects, with links to relevant authoritative resources.

Readers can use it to learn terminology and prepare questions for a health professional. The topic and source should be checked in context, especially for medicines or test results. General educational information is not an assessment of a particular person's symptoms or treatment needs.
