Which condition is characterized by high insulin levels yet ineffective cellular response?

Type 2 diabetes is characterized by high insulin levels coupled with an ineffective response by the body's cells to insulin, a phenomenon known as insulin resistance. In this condition, the pancreas produces insulin to lower blood glucose levels, but the cells are unable to use insulin efficiently. As a result, glucose accumulates in the bloodstream leading to various symptoms and long-term complications.

This contrasts with Type 1 diabetes, where the pancreas produces little to no insulin due to autoimmune destruction of insulin-producing cells. Hypoglycemia refers to abnormally low blood glucose levels, which is not related to elevated insulin levels in the same context as Type 2 diabetes. Diabetic ketoacidosis is a serious complication that typically arises in Type 1 diabetes and involves insufficient insulin leading to elevated ketone bodies, not high insulin levels. Thus, Type 2 diabetes presents the hallmark of high insulin levels alongside cellular resistance to its effects.
