Inflammation within blood vessels (Vasculitis)

Vasculitis is a group of conditions where the body's immune system causes inflammation and narrowing of blood vessels, including arteries, veins, and capillaries. This can lead to damage to the vessels and interfere with the flow of blood throughout the body.

Vasculitis can cause mild to life-threatening symptoms. The exact cause for vasculitis is unclear; however, smoking, substance abuse, unhealthy habits, chronic infections, and genetics can increase the likelihood of developing it. Based on the size of the affected blood vessels, vasculitis can result in diverse symptoms and is classified into 20 disorders. It is vital to determine the type and position of the affected blood vessels and organs before treating it. 

Maintaining a healthy lifestyle with exercise, a balanced diet, and symptom management can help minimize complications and enhance the quality of life. Treatment usually involves medication to control inflammation and prevent future episodes. Surgery may be required in severe cases.
