The Full form of PPBS is Post Prandial Blood Sugar Test. PPBS is a glucose test done on the blood that helps determine the type of sugar, also known as glucose after a certain meal. Carbohydrate foods are the primary source of energy present in the body and also the main sources of glucose. Blood glucose levels usually increase a bit after eating a meal. It is because the pancreas releases insulin which helps the body remove glucose from the blood and store it as energy. Diabetic patients will not be able to respond to the insulin and this keeps their glucose levels high. The levels remain high and over time, this can cause damage to the kidneys, nerves, eyes, and blood vessels as well. Checking levels at least one and a half hour after a meal is one way to manage this. This is because during this time period the analogue insulin would reach its maximum desired effect. Normal insulin not only takes longer but acts for a longer period as well. How often the PPBS needs to be checked depends on the individual goals to control the sugar levels in the blood. Working with a team will help one identify their goals and the testing regimen.
