Type 2 diabetes mellitus can usually be differentiated from type 1 diabetes mellitus on the basis of history and physical examination findings and simple laboratory tests (see Workup: Tests to Differentiate Type 2 and Type 1 Diabetes). Patients with type 2 diabetes are generally obese, and may have acanthosis nigricans and/or hirsutism in conjunction with thick necks and chubby cheeks.
