Blood vessel inflammation, which can affect arteries, veins, and capillaries of any size or shape, is referred to medically as vasculitis. Depending on which blood vessels are impacted and to what degree, this inflammation can cause a wide range of symptoms. Among other things, autoimmune diseases, infections, and specific drugs can induce vasculitis. Medications to control symptoms and suppress the immune system are usually part of the treatment. The specific subtype and severity of vasculitis may influence treatment approaches. Patients are usually frequently watched after starting treatment to evaluate how well they are responding to it and to keep an eye out for any potential side effects. Regular check-ups, blood tests, imaging investigations, and other evaluations to follow disease may be part of this surveillance.
