The warning signs for type 2 diabetes include:

• Unusual thirst, appetite, or fatigue.
• Frequent urination or urinary tract infections.
• Tingling or numbness in the hands or feet.
• Eye or vision problems.
• Repeated skin infections or cuts and wounds that don't heal well.

Many people with diabetes have no diabetes symptoms at all and often go many months -- or even years -- before they're diagnosed. That's because diabetes symptoms may develop slowly and emerge suddenly.
