What are the Symptoms of Diabetes?

Diabetes symptoms vary, depending on how high the blood sugar level is. Some people, especially those with prediabetes or type 2 diabetes, may not have any symptoms initially. Symptoms of type 1 diabetes tend to come on quickly and be more severe. Some of the signs and symptoms of type 1 and type 2 diabetes include:

  • Increased thirst
  • Frequent urination
  • Extreme hunger
  • Unexplained weight loss
  • Presence of ketones (toxic acids resulting from the breakdown of muscle and fat that happens when there is not enough insulin) in the urine
  • Tiredness
  • Blurred vision
  • Slow-healing sores
  • High blood pressure
  • Frequent infections (such as gum or skin infections) and vaginal or bladder infections

    Type 1 diabetes can develop at any age, but it usually begins during childhood or adolescence. Type 2 diabetes, the more common type, can develop at any age and is often preventable.
