Type 2 diabetes

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 and/or slow-healing infections (including bladder, vaginal, skin)
• erectile dysfunction in men

Type 2 diabetes is diagnosed with the following blood tests:

• Fasting blood glucose level -- diabetes is diagnosed if higher than 126 mg/dL on two 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.
