Answer

Neuropathies are the most common complication of diabetes mellitus (DM), affecting up to 50% of patients with type 1 and type 2 DM. In type 1 diabetes mellitus, distal polyneuropathy typically becomes symptomatic after many years of chronic prolonged hyperglycemia. Conversely, patients with type 2 diabetes mellitus may present with distal polyneuropathy after only a few years of known poor glycemic control; sometimes, these patients already have neuropathy at the time of diagnosis. (See Clinical Presentation.)
