The most important number on your lab report is your A1C. It's also where many people see the biggest change. As your body starts pulling sugar out of your bloodstream again, fasting glucose settles, your A1C starts coming down, and your next lab report tells a very different story. For some people, that's meant going from 6.8 into the 5s in about three months. The kind of change that gets your doctor to say, "Keep doing what you're doing."
