DD had her endo visit today. Her A1C has creeped back up after a couple of very nice numbers, so there was lots of talk about why that happened. I mentioned that she has not been prebolusing when eating foods that spike her blood sugars like a bowl of cereal or a bagel. The endo said that they no longer recommend prebolusing as new research has shown it is not helpful. In previous years we were told that prebolusing could reduce A1C's by .5. Seriously????? What the heck will be disproved next?
