Symptoms

By Mayo Clinic staff

Diabetes symptoms vary somewhat, depending on what type of diabetes you have. If you have prediabetes or gestational diabetes, you may not experience symptoms. Or you might experience some or all of the symptoms of type 1 and type 2 diabetes:

  • Increased thirst
  • Frequent urination
  • Extreme hunger
  • Unexplained weight loss
  • Fatigue
  • Blurred vision
  • Slow-healing sores
  • Frequent infections, such as gum or skin infections and vaginal or bladder infections

Although type 1 diabetes can develop at any age, it typically appears during childhood or adolescence. Type 2 diabetes, the most common type, can develop at any age and is often preventable.

When to see a doctor

  • If you suspect you may have diabetes. If you notice any possible diabetes symptoms, contact your doctor. The earlier the condition is diagnosed, the sooner treatment can begin.
  • If you've already been diagnosed with diabetes. If you've been diagnosed with diabetes, you'll need close medical follow-up until your blood sugar levels stabilize.
