The Glucose Tolerance Test (OGTT) measures how well the body processes glucose (sugar) over a period of time. It is primarily used to diagnose diabetes, prediabetes, and gestational diabetes (during pregnancy). This test evaluates the body’s ability to regulate blood sugar levels after consuming a glucose-rich drink.

Why is the OGTT Test Important?

High glucose levels after the test may indicate diabetes, insulin resistance, or gestational diabetes.
Normal glucose levels suggest proper glucose metabolism and insulin function.
This test helps detect early signs of diabetes even if fasting blood sugar appears normal.

When is the Test Recommended?

If a person has symptoms of increased thirst, frequent urination, unexplained weight loss, or fatigue.
Pregnant women are often tested between 24-28 weeks to check for gestational diabetes.
Individuals at high risk of diabetes due to family history, obesity, or metabolic syndrome.
