Question: What are the signs of diabetes?

Dr. Hibberd's answer:
Diabetes occurs when the body has insufficient insulin to function normally. This is either because the body doesn't produce enough insulin — as in Type 1 diabetes, usually diagnosed in children and adolescents — or because of increased insulin resistance — as in Type 2 diabetes, most often associated with obesity and diagnosed in adults.
Some signs and symptoms of diabetes are:
  • Increased appetite (polyphagia).
  • Increased urination (polyuria), particularly at night.
  • Sugar cravings.
  • Fatigue, lethargy.
  • Headaches, confusion, insomnia.
  • Muscle aches, decreased physical endurance or stamina.
  • Blurred vision, retinopathy, blindness.
  • Obesity, elevated triglycerides.
  • Impotence, loss of libido.
  • Renal failure.
  • Frequent infections, decreased immunity associated with hyperglycemia (elevated blood glucose), recurrent vaginal yeast infections.
  • Coronary artery disease, heart attack, stroke.
