NIDDM stands for

• A. Non-Insulin Dependent Diabetes Mellitus
• B. Non-Insulin-Dependent Diabetes Mellitus
• C. Not Insulin-Dependent Diabetes Mellitus
• D. Neonatal Insulin-Dependent Diabetes Mellitus

Answer: (A)

This tests your familiarity with diabetes abbreviations and how the terms relate to treatment needs. NIDDM stands for Non-Insulin Dependent Diabetes Mellitus. It’s the classic expansion of the acronym and historically describes type 2 diabetes, a condition where many patients do not require insulin therapy at diagnosis. The idea behind the term is the current management often starts with lifestyle changes and oral medications rather than immediate insulin. The other phrasings aren’t the standard expansion you’d expect to map to the acronym: one option uses a hyphen in a way that isn’t the conventional spelling in this context, another refers to a nonstandard wording, and the remaining option describes a different, not applicable condition. So, the best choice is Non-Insulin Dependent Diabetes Mellitus.
