What is the Oral Glucose Tolerance Test (OGTT)?

Oral Glucose Tolerance Test (OGTT) is a diagnostic tool used to assess a person's blood glucose levels.

It involves fasting overnight and then drinking a solution containing a specific amount of glucose.

Blood samples are taken at various intervals to measure how the body responds to the glucose load.

OGTT can help diagnose prediabetes and diabetes by evaluating how well the body regulates blood sugar.

The test is used to identify impaired glucose tolerance and gestational diabetes in pregnant women.

OGTT results are categorized into normal, impaired fasting glucose, impaired glucose tolerance, and diabetes.

Proper preparation for OGTT, including fasting, is essential to ensure accurate results.
