Diabetes Mellitus (Type 1)
Diabetes Mellitus
Chronic metabolic disease characterized by hyperglycemia due to defects in insulin secretion, insulin action, or both.
Includes autoimmune Type 1 diabetes, insulin–resistant Type 2 diabetes, and secondary diabetic states.

Historical note:
The term “diabetes” (Greek: “to pass through”) was described by Aretaeus of Cappadocia for excessive urination.
The sweet taste of urine (mellitus = “honey-sweet”) was documented by ancient Indian physicians (Sushruta, Charaka) and later by Thomas Willis in the 17th century.
