Medical condition search
When you search on Google for the name of a disease like "

The data comes from a number of sources, including the U.S. National Library of Medicine, as well as other sources of publicly-available data. You can learn more about these data sources below.
We try to show the most relevant facts about a condition you’ve searched for, but note that these may not be comprehensive, and are not intended to cover all possible causes, symptoms and treatments.
