Symptoms

By Mayo Clinic Staff

Diabetic ketoacidosis signs and symptoms often develop quickly, sometimes within 24 hours. For some, these signs and symptoms may be the first indication of having diabetes. You may notice:

  • Excessive thirst
  • Frequent urination
  • Nausea and vomiting
  • Abdominal pain
  • Weakness or fatigue
  • Shortness of breath
  • Fruity-scented breath
  • Confusion

More-specific signs of diabetic ketoacidosis — which can be detected through home blood and urine testing kits — include:

  • High blood sugar level (hyperglycemia)
  • High ketone levels in your urine

When to see a doctor

If you feel ill or stressed or you've had a recent illness or injury, check your blood sugar level often. You might also try an over-the-counter urine ketones testing kit. 

Contact your doctor immediately if:

  • You're vomiting and unable to tolerate food or liquid
  • Your blood sugar level is higher than your target range and doesn't respond to home treatment
  • Your urine ketone level is moderate or high

Seek emergency care if:

  • Your blood sugar level is consistently higher than 300 milligrams per deciliter (mg/dL), or 16.7 millimoles per liter (mmol/L)
  • You have ketones in your urine and can't reach your doctor for advice
  • You have multiple signs and symptoms of diabetic ketoacidosis — excessive thirst, frequent urination, nausea and vomiting, abdominal pain, shortness of breath, fruity-scented breath, confusion

Remember, untreated diabetic ketoacidosis can be fatal.
