The correct answer is
Two tests are used to find out if you have pre-diabetes. One test is called the fasting plasma glucose test (FPG). The other is the oral glucose tolerance test (OGT). The FPG is done after you fast (go without food) for eight hours. A normal fasting blood sugar level is less than 100 mg/dL. If you have the FPG test, pre-diabetes is a blood sugar level of 100 mg/dL to 125 mg/dL or greater. Diabetes is a fasting blood sugar level of 126 mg/dL or greater on two or more separate occasions. The OGT is done after eight hours of fasting and two hours after you drink a sweet beverage. If you have the OGT test, pre-diabetes is a blood sugar level of 140 mg/dL to 199 mg/dL. Diabetes is a blood sugar level of 200 mg/dL or greater.
2. If you have pre-diabetes, when are you likely to develop type 2 diabetes?

The correct answer is
The actual span of time can vary, based on exercise and weight loss. You can head off diabetes by losing weight, says the American Diabetes Association (ADA). If you lose 5 to 10 percent of your body weight and begin exercising for 30 minutes every day, you can greatly reduce your risk for developing type 2 diabetes. Be sure to check with your health care provider before beginning an exercise program. Other ways to help prevent pre-diabetes are to control your cholesterol levels and blood pressure. If you smoke, quit smoking.
3. Besides diabetes, a person with pre-diabetes is at greater risk for which disease?
You didn't answer this question.
You answered
The correct answer is
People with pre-diabetes are 1.5 times more likely to develop heart disease than those who have normal blood sugar levels, according to the ADA. A person with diabetes is two to four times more likely to develop heart disease.
4. How does being overweight add to the risk for pre-diabetes?
You didn't answer this question.
You answered
The correct answer is
Too much body fat can make your body not be able to use insulin properly, according to the National Institute of Diabetes and Digestive and Kidney Diseases (NIDDK). Your body then tries to make more insulin, but can't keep up with the demand. The extra blood sugar then builds up in the bloodstream. Exercise has the opposite effect of too much fat. It helps the insulin in your body work well.
5. Which of these is a symptom of pre-diabetes?
You didn't answer this question.
You answered
The correct answer is
People with pre-diabetes usually have no symptoms. The only way to know if you have pre-diabetes or diabetes is to have a blood test. Talk to your health care provider if you think you need a test for these conditions.
6. Who should be tested for pre-diabetes and/or diabetes?
You didn't answer this question.
You answered
The correct answer is
Anyone age 45 or older and overweight should be tested for diabetes, says the NIDDK. Because your risk rises as you get older, talk to your health care provider about testing if you are 45 or older. If you are younger than 45, you should be tested if you are overweight and at least one of these describes you: a family history of diabetes; low HDL cholesterol levels and high triglyceride levels; high blood pressure; a history of diabetes during pregnancy or a baby born weighing more than 9 pounds; or a member of a minority group that includes African American, American Indian, Hispanic American or Asian American/Pacific Islander.
7. If you have been diagnosed with pre-diabetes, when should you have your blood sugar tested again?
You didn't answer this question.
You answered
The correct answer is
If either diabetes test is positive, your health care provider may order a more complicated test to confirm the diagnosis.
