M31.6: Other giant cell arteritis

Arteries are blood vessels that transport blood away from the heart. They supply all the tissue in the body with oxygen-rich blood. With this disorder, your immune system attacks the body’s own arteries. Arteries can become inflamed as a result. Inflamed arteries can get narrow.

When arteries for the head become inflamed and get narrow, you may get pain in your head, in your temples, and when chewing. The arteries that supply the eyes may also get inflamed. This may result in impaired vision or blindness, for example.
