Which statement about diabetes mellitus is untrue?

Diabetes mellitus is a chronic condition that affects the body's ability to use insulin effectively, either due to insufficient insulin production or impaired insulin action. The statement that diabetes is curable is untrue because, while the condition can be managed through lifestyle changes, medication, and in some cases insulin therapy, it is generally regarded as a lifelong condition without a definitive cure.

Individuals with diabetes may achieve good control of their blood sugar levels and may experience periods of remission, especially in type 2 diabetes, but the underlying disorder persists, necessitating ongoing management. In contrast, the other statements reflect recognized facts about diabetes mellitus: it is indeed the leading cause of renal failure in the U.S. due to its impact on kidney function over time, it is widely recognized as the most prevalent endocrine disorder, and its pathology involves a combination of impaired insulin secretion and action which contributes to the symptoms and complications associated with the disease.
