What is diabetes? Before understanding diabetes, we should know how the sugar is processed in our body. A summary of the processing of the sugar in our body is given below: Our body uses glucose (a type of sugar) for energy, and glucose comes from food and drink intake. We should know that carbohydrates (starch and sugar) increase the blood glucose levels the most compared to other nutrients (protein and fat) we get from food and drink. Starch is a carbohydrate in food like bread, potato, and rice. Our body breaks down most of the food into sugar (glucose) and sends it to the bloodstream. When the sugar level rises in the bloodstream, it signals the pancreas to release insulin. Insulin sends the blood sugar into body cells to use as energy. Insulin (a hormone) regulates the movement of sugar from the bloodstream to cells of the body, and then sugar is used for energy. Due to insufficient or absent insulin, the sugar stays in the bloodstream and can not be used for energy....
