With Type 1 diabetes there is a phenomenon that we nickname “foot on the floor.” It means that the second some of us get out of bed, our BG starts to rise. If I get up at 6, it starts then. If I get up at 8, it starts then. It is different from dawn phenomenon that often starts in the wee hours of the morning at 3 or 4am. What often works for me is to take a bolus immediately when I get up. It helps stop the morning rise and also functions as a head start for breakfast insulin. When I bolus for my breakfast, I may or may not subtract out this bolus depending what my BG is doing and what my anticipated activity level is going to be. Obviously this is easy on the pump, not as easy with injections.
The morning hormones are very powerful and unfortunately not consistent from day to day. Eating breakfast and the insulin associated with it help to control the rise. If I don’t eat breakfast I require more insulin throughout the morning than if I do.
Good luck. Diabetes doesn’t get easier but most of us get better at dealing with it.
