Symptoms

Note: In some cases, a person can have type 2 diabetes but not have any signs and symptoms. Regular check-ups with a health care provider are an important factor in preventing or managing diabetes.

Early diagnosis of diabetes is extremely important. The earlier diabetes is diagnosed, the sooner a person can take steps to manage it well and prevent or delay any complications.

Anyone who has any of these signs and symptoms should visit a healthcare provider. The healthcare provider will decide if a test that will diagnose diabetes is warranted. Symptoms can include:

• unusual thirst;
• frequent urination;
• weight change (gain or loss);
• extreme fatigue or lack of energy;
• blurred vision;
• frequent or recurring infections;
• cuts and bruises that are slow to heal;
• tingling or numbness in the hands or feet; and
• trouble getting or maintaining an erection.
