Vasculitis is an inflammation of your blood vessels. Vasculitis causes changes in the walls of your blood vessels, including thickening, weakening, narrowing and scarring. Vasculitis is also called angiitis and arteritis. Many types of vasculitis exist.
Vasculitis can be short term (acute) or long term (chronic) and can be so severe that the tissues and organs supplied by the affected vessels don't get enough blood. The shortage of blood can result in organ and tissue damage, even death.
Vasculitis can affect anyone, though some types of vasculitis are more common among certain groups. Some forms of vasculitis improve on their own, but others require treatment — often including taking medications for an extended period of time.

General signs and symptoms common to most vasculitis types
The signs and symptoms of vasculitis vary depending on which blood vessels and, as a result, which organ systems are affected. However, general signs and symptoms that most people with vasculitis experience include:

Vasculitis occurs when your body attacks your blood vessels. It's not always clear why this happens, but an infection, some cancers, certain immune system disorders or an allergic reaction may serve as the trigger.
Blood vessels affected by vasculitis become inflamed, which can cause the layers of the blood vessel wall to thicken. This narrows the blood vessels, reducing the amount of blood — and therefore oxygen and vital nutrients — that reaches your body's tissues. In some cases, a blood clot may form in an affected blood vessel, obstructing blood flow. Sometimes instead of becoming narrower, a blood vessel may weaken and form a bulge (aneurysm), a potentially life-threatening condition.
Vasculitis with no known cause (primary vasculitis)
For many of its forms, the cause of vasculitis is unknown. These forms of vasculitis are called primary vasculitis.
Vasculitis that occurs due to another disease (secondary vasculitis)
Forms of vasculitis for which an underlying disease is the cause are called secondary vasculitis. Examples of causes of secondary vasculitis include:

Whom to see
Make an appointment with your family doctor or a general practitioner if you have signs or symptoms that worry you. If your doctor suspects that you have vasculitis, you may be referred to a specialist. What specialist you'll see depends on what type of vasculitis you have.
Specialists who treat vasculitis include:
How to prepare
Because appointments can be brief, and because there's often a lot of ground to cover, it's a good idea to be well prepared for your appointment. Try to:
Questions to ask
Your time with your doctor is limited, so preparing a list of questions will help you make the most of your time together. List your questions from most important to least important in case time runs out. For vasculitis, some basic questions to ask your doctor include:
In addition to the questions that you've prepared to ask your doctor, don't hesitate to ask questions during your appointment at any time that you don't understand something.

To diagnose vasculitis, your doctor will ask about your symptoms and past medical history and conduct a thorough physical exam. Tests and procedures used to diagnose vasculitis include:

Specific treatment for vasculitis depends on your type of vasculitis, the severity of your case and your general health. Though some types of vasculitis are self-limiting and improve on their own, such as Henoch-Schonlein purpura, others require medications.
Medications used to treat vasculitis include:

When vasculitis is identified and treated early, the prognosis is usually good. One of your greatest challenges may be coping with side effects of your medication. The following suggestions may help:
