Diabetes is not just one disease. It is a group of conditions and diseases that relate to high blood glucose levels. The American Diabetes Association describes diabetes as the diseases that result from defects in the body's ability to produce and/or use insulin. But diabetes is a complicated condition. Nine Second Opinion episodes deal specifically with diabetes. In these episodes, patients and doctors have discussed blood glucose levels, insulin resistance, blood fats, gestational diabetes, self-management, insulin pumps, kidney disease, medications and testing.
