Diabetes Mellitus
Signs and Symptoms

If you think that you have diabetes, visit your doctor immediately for a definite diagnosis. Common symptoms include the following:

  • Frequent urination
  • Excessive thirst
  • Unexplained weight loss
  • Extreme hunger
  • Sudden vision changes
  • Tingling or numbness in the hands or feet
  • Feeling very tired much of the time
  • Very dry skin
  • Sores that are slow to heal
  • More infections than usual

Some people may experience only a few symptoms that are listed above. About 50 percent of people with type 2 diabetes don't experience any symptoms and don't know they have the disease.
