Food is a source of energy for the body.
Through the process of digestion, most of the food that we consume is eventually broken down into a simple sugar called glucose. Glucose then passes into the bloodstream, where it becomes available for the body to use for growth and energy. In order for glucose to be transported to other cells in the body, a hormone produced by the pancreas, called insulin, is needed. In diabetes, the pancreas produces little or no insulin, or the cells throughout the body are unable to utilize the insulin that is being produced. The end result is a build-up of glucose in the blood, which eventually spills over into the urine before leaving the body.
