Having never worn a CGM, we often are left scratching our heads when we see a random high number on our son's blood glucose test. There have been many times when we have suspected a rebound. However, I looked it up (Somogyi remound) on Wikipedia and there is a section labeled "controversy" where it says that there is little scientific evidence to support the phenomena. Have any of you tracked a rebound with a CGM? In other words, have you seen cases where it indeed happened? I really hope it exists. I don't like the thought that a low that isn't caught will mean major, major, major issues. Not that I am relying on it or anything, but I'd like to think that there is some type of body mechanism in place in case he were to drop too low between nighttime checks.
