The purpose of doing this study is to see if continuous glucose monitoring can help people with type 1 diabetes who are sometimes unable to feel if they have a low blood glucose reading. For this study we will be using the Navigator Continuous Glucose Monitor. We think that your body may not have enough of a certain hormone that usually helps people know when they are going low. If you can keep from going low, we think there will be enough of that hormone to help you recognize the symptoms of a low before it happens.
