Uncontrolled diabetes can have serious consequences in the form of complications. The cardiovascular complications are increased risk of heart attack, stroke and transient ischemic attacks. Diabetes can also affect the blood flow to lower limbs leading to peripheral vascular disease. Retinopathy due to diabetes is one of the commonest causes of blindness. Diabetes is also one of the most common causes of kidney failure requiring hemodialysis or a kidney transplant. Diabetic neuropathy, foot ulcers, cardiac autonomic dysfunction, gastroparesis, sexual dysfunction, skin disorders, infections, hearing impairment, memory impairment, and depression are notable others.
