Type 2 Diabetes is a condition in which the body either does not produce enough insulin or does not make efficient use of it. Insulin is a hormone needed to convert food into glucose, a sugar that the body uses for energy. Without enough insulin, glucose can accumulate in the blood, and can cause serious health problems such as heart disease and strokes and organ damage...

Again, you will need to fast for at least 8 hours before this test, and while the test is being performed. Your physician will give you a sugary liquid to drink. Blood tests will be drawn before the test begins, and again at two hours afterward. While not common, your doctor may also request that blood be drawn at different intervals in addition to the standard ones listed above. Normally, blood sugar should return to normal within 3 hours. If blood sugar levels are elevated beyond the test, it may indicate that you are insulin resistant.
No matter what your results are from the testing, it is important to follow up appropriately with your physician. They may want you to repeat the test now or within a specific time frame (such as in one year). If the test does come back abnormal, you may want to see a nutritionist for dietary advice or a doctor who specializes in managing diabetes.
Hope that this is helpful
