Oral Glucose Tolerance Test

An Oral Glucose Tolerance Test (OGTT) is a medical procedure used to evaluate how well your body processes sugar. After fasting overnight, you drink a sugary liquid, and your blood is tested at intervals—usually before drinking and then 2 hours after—to measure blood sugar levels. This helps identify conditions like diabetes or insulin resistance by showing how effectively your body manages glucose. The test provides valuable information about your metabolic health and guides appropriate treatment or lifestyle adjustments.
