Q Why do diabetics have poor circulation?
There are many side effects of diabetes; one of the most common is poor circulation. As the disease progresses, this causes a build up of sugar complexes in the arteries and veins in the body. Diabetes is also a risk factor for increase plaque formation on the walls of the vessels, or atherosclerosis. Both of these factors contribute to the narrowing of the vessels and poor circulation causing symptoms such as cramping or pain in the legs after walking a certain distance, or intermittent claudication.
