Why does the body sometimes exhibit hyperglycemia despite insulin injections in Type 2 diabetics?

A)Increased glucagon production compensates fully
B)Target cells show insulin resistance
C)The pancreas depletes insulin reserves
D)Kidneys excrete injected insulin rapidly

💡 Explanation

Insulin resistance explains hyperglycemia in Type 2 diabetics because cellular receptors become less responsive to insulin signaling, preventing glucose uptake into cells. Therefore, blood glucose remains high, rather than insulin deficiency being the primary cause, or immediate insulin excretion by the kidneys.
