Vasculitis is a medical condition characterized by inflammation of the blood vessels, which can affect arteries, veins, and capillaries. This inflammation can lead to narrowing or blockage of the vessels, reducing blood flow to various organs and tissues. Symptoms may include fever, fatigue, weight loss, and pain in affected areas. There are several types of vasculitis, each with different causes and effects. Some forms are associated with autoimmune diseases, where the body's immune system mistakenly attacks its own tissues. Treatment often involves medications to reduce inflammation and suppress the immune response, helping to manage symptoms and prevent complications.
