Request an appointment. Vasculitis is an inflammation of your blood vessels. It causes changes in the walls of blood vessels, including thickening, weakening, narrowing and scarring. These changes restrict blood flow, resulting in organ and tissue damage. There are many types of vasculitis, and most of them are rare. Vasculitis might affect just one organ, such as your skin, or it may involve several. The condition can be short term (acute) or long lasting (chronic). Vasculitis can affect anyone, though some types are more common among certain groups.
This inflammation is called vasculitis. It usually affects the small blood vessels in the skin (capillaries). It can also affect blood vessels in the bowel and the kidneys. When the blood vessels get inflamed, they can bleed into the skin, causing a rash that is called purpura. The intestines and the kidneys may also bleed.
