Complications of Diabetes:

Eight out of ten diabetics develop eye problems.
Diabetes is the leading cause of new blindness in developed countries.
Diabetics are 18 times more likely to experience serious kidney damage than are nondiabetics. Some 25 percent of kidney dialysis patients are diabetics.
Diabetes is a potent promoter of atherosclerosis (plugging of the arteries).
The result is that diabetes more than doubles the risk of heart attacks and strokes.
It can also lead to:
sexual impotence,
hearing impairment,
intermittent claudication (disabling leg cramps)
and gangrene (Half of all foot and leg amputations in adults are from this cause).
