This illness is a result of an imbalance of hormones, insulin, produced in the pancreas. Insulin plays an important role in how the body uses food. Insulin enables the cells in the bloodstream to absorb and use glucose for fuel. If the pancreas produces too little or no insulin or if the insulin doesnt work properly the person may become diabetic. Therefore, diabetics are not able to properly convert food into fuels needed by the body to function, which can seriously lead to physical consequences. The pancreas, located behind the stomach, is a long, thin organ about the length of the hand. It is the organ that is responsible for the development of diabetes. The pancreas has two different types of cells, called alpha and beta cells, which produce insulin. Insulin is responsible for breaking down food that enters the body, turning into fuel that can be used by the body, and distributing it to the various parts of the body. The fuels needed for the body to function are known as glucose. Glucose is sugar manufactured when the carbohydrates we eat are digested.

Attempts to transplant part of a normal pancreas into a diabetic have not been very successful. The operation is a difficult one and only about 40 percent of the transplanted organs are still working. One major problem is that some way has to be found to stop the digestive juices leaking out and digesting the insulin. Pancreatic transplants have mainly been attempted ...
