Definition The glucose tolerance test is a laboratory method to check how the body breaks down (metabolizes) sugar. Alternative Names Oral glucose tolerance test How the test is performed The most common glucose tolerance test is the oral glucose tolerance test (OGTT). You cannot eat or drink anything after midnight before the test. For the test, you will be asked to drink a liquid containing a certain amount of glucose. Your blood will be taken before you do this, and again every 30 to 60 minutes after you drink the solution. The test takes up to 3 hours. The intravenous glucose tolerance test (IGTT) is rarely used. In this test, glucose is injected into your vein for 3 minutes. Blood insulin levels are measured before the injection, and again at 1 and 3 minutes after the injection, although the timing may vary. How to prepare for the test Make sure you eat normally for several days before the test. Do not eat or drink anything for 8-10 hours before the test. You cannot eat during the test. As...

Expertise and extensive experience have an important place in information about diabetes . But first impressions count too. The experts can miss key experiences when they aren’t coming fresh to a topic. Today I am coming to you fresh from my initial experience with actually using a continuous glucose monitor . I started to wear it on Friday afternoon after two superb technicians from Medtronic MiniMed trained me for more than two hours in its use. Since then, the device tells me every five minutes what my blood glucose level is. Continuous meters actually measure interstitial fluid, not blood glucose, but they run close together. Interstitial fluid lags about a quarter of an hour after rapid changes in blood glucose levels for two reasons. One is the body’s natural lag, and the other is the slight lag that measuring it introduces. That’s why I didn’t throw away my old blood glucose meters. When the continuous meter reports that our levels are too low or too high, we...
