8. c. Hair loss is not a typical symptom of diabetes.

Many people think that the classic diabetes symptoms—increased thirst and frequent urination—are the only signs of the disease, said Susan Zatopek, MSN, RN, a certified diabetes educator and diabetes program director at the Austin Diagnostic Clinic Diabetes Management Center. Warning signs of type 1 diabetes also include extreme hunger, unusual weight loss, extreme fatigue, and irritability. Warning signs of type 2 diabetes include the type 1 symptoms and frequent infections, blurred vision, cuts that are slow to heal, tingling or numbness in the extremities, and recurring skin, gum, or bladder infections.
