You may have type 2 diabetes for years before you start to have symptoms. 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 (especially at night, which can lead to insomnia )
  • Increased thirst
  • Increased hunger
  • Fatigue
  • Blurry vision
  • Irritability
  • Frequent or recurring infections
  • Slow wound healing
  • Foot ulcers
  • Numbness or tingling in the hands or feet
  • In women: frequent vaginal yeast infections
  • Problems with gums and teeth
  • Itching
  • Impotence
  • Angina (chest pain)
