Diabetes mellitus is a generalized, chronic metabolic disorder. If the disease is prolonged, it is usually complicated by degenerative changes of the blood vessels, the retina, the kidney, and the nervous system.

Relationships of diabetic polyneuropathy and some factors, age, fasting blood sugar level, duration, and glycosylated hemoglobin (HbAlc), affecting on diabetic polyneuropathy, were evaluated. Ninety-two TypeⅡ diabetic patients with or without polyneuropathy related symptom were studies. Polyneluropathy was diagnosed by the conventional electrodiagnosis of sensory and motor conduction studies and electromyography.

It is concluded that the fasting sugar level and duration of diabetes mellitus was significantly different between the group with polyneuropathy and the group without polyneluropathy in electrodiagnosis. But the differences of age and HbAlc level were not significant between the groups, statistically.
