What Is Vasculitis?
Vasculitis is a group of conditions that causes inflammation in the blood vessels.
It can be:
- Systemic, affecting multiple systems in the body.
- Isolated to a specific blood vessel group.
Vasculitis is complex and can range from mild to life threatening.
It may happen once in a person’s life and never recur. In some cases, vasculitis can recur after successful treatment.
Some people need lifelong treatment for vasculitis.
Vasculitis causes and risk factors
Vasculitis happens when your immune system attacks your blood vessels by mistake.
While doctors don't know exactly why this happens, some risk factors can include:
- Autoimmune disorders like lupus, rheumatoid arthritis, and scleroderma.
- Medicines.
- Infections like hepatitis B, hepatitis C, or viral illness.
- Blood cancers.
Vasculitis complications
Vasculitis can damage blood vessels, causing them to become thick, weak, narrow, or scarred. This can limit blood flow, keeping your organs and tissues from getting the oxygen and nutrients they need.
Complications from vasculitis can include:
- Organ damage.
- Blood clots.
- Aneurysm, or a bulge or weak spot in a blood vessel.
- Vision loss or blindness.
- Infections like pneumonia and sepsis (blood infection).
- Limb loss.
