Symptoms of Type 2 Diabetes

You may have type 2 diabetes for years before you start to have symptoms. Also, if your symptoms are initially mild, and they gradually increase, they may be hard to notice. In fact, up to 40% of type 2 diabetes patients have no symptoms at the time of diagnosis.

Symptoms of type 2 diabetes may be related either to high blood sugar or due to diabetic complications affecting the eyes, blood vessels and heart, or nerves.

Symptoms may include the following:

  • Weight loss
  • Increased urination
  • Increased thirst
  • Increased hunger
  • Fatigue
  • Blurry vision
  • Irritability
  • Frequent or recurring infections
  • Slow wound healing
  • Numbness or tingling in the hands or feet
  • In women: frequent vaginal yeast infections
  • Problems with gums
  • Itching
  • Impotence
  • Angina
  • Painful leg muscles when walking
