Are there any complications to diabetes?
Yes, and they are quite serious. When diabetes is poorly managed, health-threatening complications can develop. Acute complications such as a coma can occur when blood glucose gets abnormally high, or seizures or loss of consciousness when it gets abnormally low (after too high a dose of anti-diabetic medication, for instance).
Meanwhile, over time diabetes can harm the heart, blood vessels, eyes, kidneys, and nerves. It can also increase the risk of stroke and heart disease. The combination of a reduced blood flow and nerve damage can result in foot ulcers and infection, finally leading to amputation. In the eye, damage to the retina can cause blindness. It is also one of the leading causes of kidney failure.1
