Discussion 3

Peripheral vascular disease (PVD) is a very common condition in the United States and is a leading cause of disability among people older than 50. It is more common in smokers, people with diabetes, hypertension and high cholesterol. Many people seem to think that this is a normal part of aging, and that nothing can be done or that the only alternative is surgery. Today, however, surgery is only one of several effective treatments available for peripheral vascular disease. Research and discuss the some of the debilitating issues associated with PVD and one non-surgical treatment that would be helpful for people with this condition.
