Diabetes Mellitus ( 49 Questions)
Which of the following pathophysiological mechanisms contributes to hyperglycemia in type 2 diabetes mellitus?
This choice is incorrect. Autoimmune destruction of pancreatic beta cells is characteristic of type 1 diabetes, not type 2.
This choice is incorrect. Increased sensitivity of cells to insulin would result in improved glucose uptake and reduced hyperglycemia.
In type 2 diabetes, insulin resistance occurs, meaning that the body's cells do not respond effectively to the action of insulin. This leads to decreased glucose uptake by cells and elevated blood sugar levels.
This choice is incorrect. Excess insulin production by the pancreas is not a typical mechanism in type 2 diabetes.
