Print OverviewVasculitis involves inflammation of the blood vessels. The inflammation can cause the walls of the blood vessels to thicken, which reduces the width of the passageway through the vessel. If blood flow is restricted, it can result in organ and tissue damage. There are many types of vasculitis, and most of them are rare. Vasculitis might affect just one organ, or several. The condition can be short term or long lasting. Vasculitis can affect anyone, though some types are more common among certain age groups. Depending on the type you have, you may improve without treatment. Most types require medications to control the inflammation and prevent flare-ups.Products & ServicesA Book: Mayo Clinic Family Health BookNewsletter: Mayo Clinic Health Letter — Digital EditionShow more products from Mayo Clinic Types Behcet's disease Buerger disease Churg-Strauss syndrome Cryoglobulinemia Giant cell arteritis Granulomatosis with polyangiitis Henoch-Schonlein purpura Kawasaki disease Takayasu's arteritis SymptomsGeneral signs and symptoms of most types of vasculitis include: Fever Headache Fatigue Weight loss General aches and pains Other signs and symptoms are related to the parts of the body affected, including: Digestive system.

Sorry something went wrong with your subscription Please, try again in a couple of minutes Retry CausesThe exact cause of vasculitis isn't fully understood. Some types are related to a person's genetic makeup. Others result from the immune system attacking blood vessel cells by mistake. Possible triggers for this immune system reaction include: Infections, such as hepatitis B and hepatitis C Blood cancers Immune system diseases, such as rheumatoid arthritis, lupus and scleroderma Reactions to certain drugs Risk factorsVasculitis can happen to anyone. Factors that may increase the risk of certain disorders include: Age. Giant cell arteritis rarely occurs before the age of 50, while Kawasaki disease is most common in children younger than 5 years old. Family history. Behcet's disease, granulomatosis with polyangiitis and Kawasaki disease sometimes run in families. Lifestyle choices. Using cocaine can increase your risk of developing vasculitis. Smoking tobacco, especially if you're a man younger than 45, can increase your risk of Buerger's disease. Medications. Vasculitis can sometimes be triggered by medications such as hydralazine, allopurinol, minocycline and propylthiouracil. Infections. Having hepatitis B or C can increase your risk of vasculitis. Immune disorders. People who have disorders in which their immune systems mistakenly attack their own bodies may be at higher risk of vasculitis. Examples include lupus, rheumatoid arthritis and scleroderma. Sex. Giant cell arteritis is much more common in women, while Buerger's disease is more common in men. ComplicationsVasculitis complications depend on the type and severity of your condition. Or they may be related to side effects of the prescription medications you use to treat the condition. Complications of vasculitis include: Organ damage. Some types of vasculitis can be severe, causing damage to major organs. Blood clots and aneurysms. A blood clot may form in a blood vessel, obstructing blood flow. Rarely, vasculitis will cause a blood vessel to weaken and bulge, forming an aneurysm (AN-yoo-riz-um). Vision loss or blindness. This is a possible complication of untreated giant cell arteritis. Infections. Some of the medications used to treat vasculitis may weaken your immune system. This can make you more prone to infections.
