Impaired glucose tolerance is commonly called

A) diabetes.
B) hypoglycemia.
C) hyperglycemia.
D) prediabetes.

Impaired glucose tolerance is a condition in which the body is unable to use insulin effectively, leading to high blood sugar levels. This condition is often considered a precursor to diabetes and is also known as prediabetes. Hypoglycemia and hyperglycemia are conditions of low and high blood sugar levels, respectively, and are not synonymous with impaired glucose tolerance. Diabetes is a more severe form of glucose intolerance.
