What Causes Type 2 Diabetes?

Although it is more common than type 1 diabetes, type 2 diabetes is less well understood. It is likely caused by multiple factors and not a single problem.

Type 2 diabetes can run in families, but the exact nature of how it's inherited or the identity of a single genetic factor is not known.

What Are the Symptoms of Type 2 Diabetes?

The symptoms of type 2 diabetes vary from person to person but may include:

  • Increased thirst
  • Increased hunger (especially after eating)
  • Dry mouth
  • Nausea and occasionally vomiting
  • Frequent urination
  • Fatigue (weak, tired feeling)
  • Blurred vision
  • Numbness or tingling of the hands or feet
  • Frequent infections of the skin or urinary tract

Rarely, a person may be diagnosed with type 2 diabetes after presenting to the hospital in a diabetic coma.

How Is Type 2 Diabetes Diagnosed?

If your health care provider suspects type 2 diabetes, he or she will first check for abnormalities in your blood (high blood sugar levels). In addition, he or she may look for sugar or ketone bodies in your urine.

Tests used to diagnose type 2 diabetes include a fasting plasma glucose test or a casual plasma glucose test.

Complications of Type 2 Diabetes

If your type 2 diabetes isn't well controlled, there are a number of serious or life-threatening complications you may experience, including:

  • Retinopathy. People with type 2 diabetes may already have abnormalities in the eyes related to the development of diabetes. Over time more and more people who initially do not have eye problems related to the disease will develop some form of eye problem. It is important to control not only sugars but blood pressure and cholesterol to prevent progression of eye disease. Fortunately, the vision loss isn't significant in most.
  • Kidney damage. The risk of kidney disease increases over time, meaning the longer you have diabetes the greater your risk. This complication carries significant risk of serious illness -- such as kidney failure and heart disease.
  • Poor blood circulation and nerve damage. Damage to nerves and hardening of the arteries leads to decreased sensation and poor blood circulation in the feet. This can lead to increased infections and an increased risk of ulcers which heal poorly and can in turn significantly raises the risk of amputation. Damage to nerves may also lead to digestive problems, such as nausea, vomiting, and diarrhea.
