Medical science has not developed a reliable means of preventing vasculitis as of this writing, per Medscape. However, anything that works to reduce inflammation in the body may help to prevent or reduce inflammation of the blood vessels. While noting that inflammation comprises a critical and complicated system of chemical reactions aimed at defending the body against illness and injury, the University of Wisconsin School of Medicine and Public Health offers a handout detailing various steps that may be taken to reduce levels of unnecessary inflammation. These include not smoking (remember, Buerger’s disease may resolve through the cessation of smoking, according to Johns Hopkins Vasculitis Center), and getting adequate exercise and good quality sleep, stress management, and weight management.
