Vasculitis is an inflammation of the blood vessels. It happens when the body's immune system attacks the blood vessel by mistake. The cause is often unknown. Vasculitis can affect arteries, veins and capillaries. Arteries are vessels that carry blood from the heart to the body's organs. Veins are the vessels that carry blood back to the heart. Capillaries are tiny blood vessels that connect the small arteries and veins.
- When a blood vessel becomes inflamed, it can
- Narrow, making it more difficult for blood to get through
- Close off completely so that blood can't get through
- Stretch and weaken so much that it bulges and may burst and cause dangerous bleeding inside the body
Symptoms of vasculitis can vary, but usually include fever, swelling and a general sense of feeling ill. The main goal of treatment is to stop the inflammation. Steroids and other medicines to stop inflammation are often helpful.
