Postprandial glucose test is a test used to measure the body's postprandial glucose levels to check for diabetes.
When you have diabetes, your body does not produce enough insulin to control blood sugar, leading to too high blood sugar levels causing serious health problems such as nerve and eye damage.
Glucose test 2 hours after eating will help look at the body's response to glucose and starch after eating.
2. Purpose of postprandial glucose testing
When food is digested in the stomach, the concentration of serum glucose or blood sugar will increase sharply. In response to this condition, the pancreas releases insulin to move sugar from the blood into the cells of muscles and other tissues. Therefore, within 2 hours of eating, insulin and blood glucose levels will return to normal.
At this time, the postprandial glucose test will know the blood glucose concentration. If glucose remains high, the patient is likely to have diabetes.
