Type 2 diabetes is best described as?

Type 2 diabetes is best described as?

• A. A condition characterized by insulin resistance with relative insulin deficiency causing chronic hyperglycaemia.
• B. Autoimmune destruction of pancreatic beta cells resulting in absolute insulin deficiency and hyperglycaemia.
• C. A deficiency of glucagon causing low blood sugar.
• D. A hormonal disorder unrelated to insulin.

Answer: (B)

Type 2 diabetes is defined by insulin resistance with relative insulin deficiency, which leads to chronic high blood glucose. The body's tissues don’t respond well to insulin, so glucose remains in the blood even though insulin is present. The pancreas may compensate by making more insulin at first, but over time it often can’t keep up, resulting in ongoing hyperglycemia. This contrasts with Type 1 diabetes, where autoimmune destruction of the beta cells causes an absolute lack of insulin. A deficiency of glucagon wouldn’t cause high blood glucose, since glucagon raises blood sugar; its absence would tend to lower it. So the best description is insulin resistance with a gradual, relative shortage of insulin causing persistent hyperglycemia.
