Insulin - Post Prandial
What is Insulin-PP?
The Insulin Post-Prandial test, also known as a two-hour postprandial or two-hour PPG sugar test, is done to detect diabetes. In the case of diabetes, the body doesn't make enough insulin to keep your blood sugar in check. This leads to elevated blood sugar levels, and over time this can lead to serious health problems including heart, nerve, kidney, and eye damage.
The insulin test is performed if you have symptoms like sweating, hunger, palpitations, blurred vision, and fainting. The normal insulin postprandial levels range between 5.00 uU/mL - 55.00 uU/mL. The levels are increased in case of obesity and type II diabetes. The PPG levels are decreased in the case of untreated type 1 diabetes mellitus.
Why is Insulin-PP done?
The insulin postprandial test is done:
If you have signs or symptoms of low blood glucose (hypoglycemia) like sweating, hunger, confusion, blurred vision, dizziness, palpitations, and sometimes fainting
In case of suspected type 2 diabetes, polycystic ovarian syndrome, heart disease, or metabolic syndrome
To determine the start of insulin therapy if you are a diabetic
In the case of suspected insulinoma
To detect insulin resistance
What does Insulin-PP Measure?
The insulin postprandial test measures the levels of sugar in the blood after two hours of having food. If a person has diabetes, it means the body is not able to make sufficient insulin to keep blood sugar in check. This can lead to high sugar levels in the blood which can further lead to serious health problems such as eye and nerve damage.
This test tells how the body gives a response to sugar and starch after ingestion of a meal. As the food is digested in the stomach, the levels of blood sugar rise high. In response, the pancreas releases insulin so that the sugar is transferred from the blood to the cells of muscles and other tissues where it can be used as fuel. Ideally, within two hours of intake of a meal, the insulin and blood glucose levels should return to normal. In case, the blood glucose still remains high, there are chances that the person might have diabetes.
Interpreting Insulin-PP results
The normal insulin postprandial levels range between 5.00 uU/mL - 55.00 uU/mL.
