3. Weight loss
Although diabetes is often cited as a risk factor for obesity, the onset of diabetes can cause rapid weight loss. The inability of the body to absorb glucose tricks it into thinking that starvation is the problem, and the body will then begin to use protein from muscle tissue for fuel, resulting in weight loss. A loss of 10 or 20 pounds over a period of two or three months is not considered a normal, healthy weight loss.
