Patient was educated on incretin and insulin secretion as follows:

1. In a normal individual, after having a meal, food is broken down and digested in the stomach and intestines.
2. Blood sugars rise, when carbohydrates are broken down and sugars are absorbed in the intestines.
3. Rise in the blood sugars stimulate release of a natural hormone in the human body, called incretin.
4. Incretin brings about the secretion of insulin from the pancreas.
5. After a while, sugars in the blood are taken up by the tissues, such as liver and muscle, due to the action of insulin, which leads to gradual fall of blood sugar.
6. As the blood sugar decreases, the stimulus for fresh incretin secretion gradually subsides.
7. An enzyme called dipeptidyl peptidase breaks down the active incretin already in circulation, thereby, reducing the stimulus for insulin secretion from pancreas.
