Overview Symptoms Treatment Prevention
Diabetes
Alternative Names: Diabetes mellitus Symptoms: High blood levels of glucose can cause several problems, including frequent urination, excessive thirst, hunger, fatigue, weight loss, and blurry vision. However, because type 2 diabetes develops slowly, some people with high blood sugar experience no symptoms at all. Text Continues Below Symptoms of type 1 diabetes: Increased thirst Increased urination Weight loss in spite of increased appetite Fatigue Nausea Vomiting Symptoms of type 2 diabetes: Increased thirst Increased urination Increased appetite Fatigue Blurred vision Slow-healing infections Impotence in men Signs and tests: A urine analysis may be used to look for glucose and ketones from the breakdown of fat. However, a urine test alone does not diagnose diabetes. The following blood glucose tests are used to diagnose diabetes: Fasting blood glucose level -- diabetes is diagnosed if higher than 126 mg/dL on two occasions. Levels between 100 and 126 mg/dl are referred to as impaired fasting glucose or pre-diabetes. These levels are considered to be risk factors for type 2 diabetes and its complications. 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 (This test is used more for type 2 diabetes.) Page:  1 | 2 | Next >>
