Some people will have no symptoms before they are diagnosed with diabetes.

Others may notice these symptoms as the first signs of developing diabetes or when the blood sugar is high:

  • Increased thirst
  • Frequent urination
  • Unexplained weight loss (even though you are eating and feel hungry)
  • Increased hunger (even after eating)
  • Feeling tired, weak, or fatigued
  • Blurred vision
  • Dry mouth
  • Headaches

If left untreated, especially in type 1 diabetes, extremely high blood sugar may result in diabetic ketoacidosis (DKA).  The warning signs of DKA are:

  • Deep, rapid breathing
  • Extreme thirst or very dry mouth
  • Flushed skin
  • Fruity breath odor
  • Nausea or vomiting, unable to keep down fluids
    (If vomiting continues for more than 2 hours, please contact your health care provider.)
  • Stomach pain
  • A hard time paying attention, or confusion

Ketoacidosis is extremely dangerous and serious.  If you have any of the above symptoms, please contact your health care provider immediately or go to the nearest emergency room or hospital.

Low blood sugar  can develop quickly in people with diabetes who are taking insulin. Symptoms typically appear when the blood sugar level falls below 70. Watch for:

  • Headache
  • Hunger
  • Nervousness
  • Rapid heartbeat (palpitations)
  • Shaking
  • Sweating
  • Weakness
