PPBS Test (Post Prandial Blood Sugar): Why and How is it Done?

What Is Post Prandial Blood Sugar or PPBS Test?

The post prandial blood sugar test or PBBS test detects how the body responds to starch and sugar after a meal. It evaluates if the function of insulin is effective to keep normal blood sugar levels.

This test helps to detect the blood sugar levels post-meal, which is recommended in people at risk of diabetes, prediabetics, and diabetics.

When the body is unable to produce or use enough insulin to control the blood glucose levels, the person’s blood sugar levels appear high. If the high blood sugar levels are not controlled, it can cause severe health problems.

After a meal the blood sugar levels increase significantly till the food is digested completely. In response to this, the pancreas releases insulin that helps these sugars to move from the blood into the muscle cells and other tissues to produce energy in the body.

Within two hours of the meal, the blood sugar levels and insulin return to normal. However, if the blood sugar levels still remain high, this indicates a person has diabetes.
