Overview Symptoms Treatment Prevention

Type 2 diabetes

Noninsulin-dependent diabetes mellitus; Diabetes - type 2

Often, people with type 2 diabetes have no symptoms at all. If you do have symptoms, they may include:

• Increased thirst
• Increased urination
• Increased appetite
• Fatigue
• Blurred vision
• Frequent or slow-healing infections
• Erectile dysfunction

Type 2 diabetes is diagnosed with the following blood tests:

• Fasting blood glucose level -- diabetes is diagnosed if higher than 126 mg/dL on2 occasions.
• Random (non-fasting) blood glucose level -- diabetes is suspected if higher than 200 mg/dL and accompanied by the classic symptoms of increased thirst, urination, and fatigue (this test must be confirmed with a fasting blood glucose test).
• Oral glucose tolerance test -- diabetes is diagnosed if glucose level is higher than 200 mg/dL after 2 hours.
