What is the PPBS test?
The Postprandial glucose test or 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 main sources of glucose and it is a primary source of energy present in the body.
Blood glucose levels generally 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. Those suffering from diabetes 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 eyes, nerves, kidneys and blood vessels as well.
The postprandial test is generally undertaken for two hours and it precisely measures the glucose in the blood two hours after eating a meal. The timing for the same begins from the start of the meal. After 2 hours, blood sugar levels generally drop back to normal for healthier individuals but it can remain high for those with diabetes. It thus serves as a final test for those who may have diabetes and whether the person with diabetes is able to manage his blood sugar levels.
How to deal with the high postprandial sugar levels:
Checking levels at least 90 minutes 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.
For those who have type 1 diabetes, the blood sugar levels need to be anywhere between 5 and 9 mmol/litre at a time period of just about 90 minutes after eating. Doctors may recommend another postprandial level depending on the patient’s health state and their personal needs.
