Symptoms

High blood glucose can cause symptoms in both types of diabetes.  Symptoms may include

  • Increased thirst
  • Increased urination
  • Constant hunger
  • Weight loss
  • Blurred vision
  • Fatigue, or a feeling of being tired
  • Frequent yeast infections
  • Very slow healing of wounds or sores

People with type 1 diabetes may have noticeable early symptoms that often come on suddenly. Type 2 diabetes may occur without any symptoms, or symptoms may develop gradually.
