Giant Cell Arteritis, also known as temporal arteritis, is a condition characterized by the inflammation of the arteries’ lining. It commonly affects the arteries in the head, especially those on the temples. The inflammation obstructs blood flow.
The leading cause of giant cell arteritis is still unknown, but it is considered an autoimmune disease. In this case, the immune system is the one that attacks the lining of the arteries, which affects the blood flow in the head and the brain.
Those who are at risk of having giant cell arteritis are adults. It rarely occurs in those under 50 years of age. The symptoms start to show mostly from the age of 70. Also, women are at a higher risk of about two times more as compared to men.
When giant cell arteritis is left untreated, it may cause serious complications such as blindness.
