During digestion, foods that contain carbohydrates are converted into glucose. Most of this glucose is sent into your bloodstream, causing a rise in blood glucose levels, which signals your pancreas to produce insulin. The insulin signals cells throughout your body to take in glucose from your bloodstream.
Postprandial refers to the blood glucose levels post a meal. This test is done to see how your body responds to sugar and starch after you eat a meal. As you digest the food in your stomach, blood glucose, or blood sugar, levels rise sharply.
For fasting sugar you cannot eat anything. For post prandial you can eat a banana before the test.
In type 2 diabetes, the pancreas makes insulin, but the cells don't respond to it as they should. This is called insulin resistance.
One gram of sugar will result in the spike of 5mg/dl blood glucose levels. Hence, diabetics are advised to take less or no sugar at all.
