In type 2 diabetes, the body's ability to compensate with increased insulin production is impaired.

• A. It can fully compensate by increasing insulin production.
• B. It never involves insulin.
• C. It only occurs with autoimmune destruction.
• D. It involves impaired insulin action with insufficient compensatory insulin production.

Answer: (D)

In type 2 diabetes, insulin resistance means the body's cells don't respond well to insulin. The pancreas tries to compensate by boosting insulin production, but over time the beta cells can’t sustain that effort, so insulin production becomes insufficient to overcome the resistance. That combination—impaired insulin action with not enough compensatory insulin—drives the high blood glucose seen in this condition. If insulin production could fully compensate, blood glucose would stay normal, which isn’t the typical course of type 2. Saying insulin isn’t involved ignores the central role of insulin resistance and secretion. Autoimmune destruction is more characteristic of type 1 diabetes, not the usual story in type 2.
