CGM sensor readings are taken from interstitial fluid, a thin layer of fluid that surrounds the tissue cells below your skin. As carbohydrates are digested, glucose enters your bloodstream before it is absorbed into the interstitial fluid. This is why testing your blood glucose may result in a different reading than a scan of interstitial fluid. Eventually, sensor readings catch up to blood glucose readings giving you a more holistic look at your levels, rather than only capturing one moment in time.
