No. Sugar by itself does not cause diabetes. Diabetes is the inability to metabolize sugar due to lack / resistance to insulin; the pancreas produce Insulin among other hormones which help in the metabolism of glucose (sugar); those who consume lots of sugar may cause their pancreas to over work and if they were prone to diabetes may develop the disease earlier. Obesity may cause resistance to insulin.
