Vasculitis

Vasculitis is a group of disorders characterized by inflammation of the blood vessels, which can cause them to weaken, narrow, or become blocked, leading to tissue and organ damage. The condition can affect vessels of any size—small, medium, or large—and may involve organs such as the skin, kidneys, lungs, and nerves. Symptoms vary depending on the type and location of affected vessels but often include fever, fatigue, weight loss, skin rashes, numbness, and organ-specific problems like kidney dysfunction or breathing difficulties. Causes can be autoimmune, infections, medications, or unknown, and treatment usually involves suppressing inflammation with medications such as corticosteroids or other immunosuppressants to prevent complications.
