Does sugar tolerance require fasting

Glucose tolerance test is a glucose tolerance test, usually fasting.

Fasting state can more accurately assess the basal blood glucose level. If the test is performed after eating, the digestion and absorption of food will increase blood glucose, which cannot truly reflect the body's own glucose metabolism ability and interfere with the judgment of islet beta cell secretion function. If there is no fasting, it may lead to wrong diagnosis results, such as underestimating the degree of islet beta cell dysfunction, or delaying the discovery and treatment of related diseases such as diabetes.

In order to obtain accurate glucose tolerance test results, it is necessary to strictly maintain fasting state and follow the doctor's instructions to provide reliable basis for clinical diagnosis and treatment.
