Ketosis-resistant diabetes mellitus, also known as type 2 diabetes, is a chronic metabolic disorder that affects millions of people around the world. While there are no perfect synonyms for this condition, other terms have been used to refer to it, such as non-insulin dependent diabetes mellitus (NIDDM), adult-onset diabetes, and hyperglycemia. These terms illustrate the different aspects of the disorder, such as the importance of insulin in regulating blood sugar levels, the age at which it typically develops, and the high blood sugar levels that characterize the condition. Regardless of the terminology used, ketosis-resistant diabetes mellitus is a significant health concern that requires proper management and treatment.
