Other potential side effects of Type 2 diabetes include Alzheimer's disease, hearing impairment, foot damage, heart disease and several skin conditions, explains Mayo Clinic. The risk of developing cardiovascular problems, such as angina, stroke, atherosclerosis and high blood pressure, is much higher in patients with diabetes. Type 2 diabetes leaves patients more susceptible to hearing problems and skin conditions, such as fungal and bacterial infections. Nerve damage in a patient's foot can impair the person's ability to realize cuts and blisters are present, notes Healthline. This can lead to serious infections that may require leg, foot or toe amputation.

Skin conditions are often the first sign that a patient has diabetes, explains the American Diabetes Association. Skin problems that occur more often in people with diabetes include eruptive xanthomatosis, diabetic blisters, diabetic dermopathy and necrobiosis lipoidica diabeticorum. Other bacterial infections, such as styes, folliculitis, boils and carbuncles, commonly occur in those with Type 2 diabetes as well.
