What condition is characterized by an inability to respond to high blood glucose levels?

Hypoglycemia
Diabetes
Obesity
Hyperglycemia

The correct answer is: Diabetes

The condition characterized by an inability to respond effectively to high blood glucose levels is diabetes. In diabetes, the body either does not produce enough insulin, which is the hormone responsible for regulating blood sugar levels, or the body's cells do not respond properly to insulin, leading to elevated blood glucose levels. This inability can result in various health complications over time if not managed properly. Managing diabetes typically involves monitoring blood sugar levels, dietary changes, and, in many cases, medication or insulin therapy to help control those levels. Understanding the role of insulin and its function is crucial in grasping how diabetes affects the body and why maintaining proper glucose levels is vital for overall health.
