Help me interpret BS rise many hours after eating?
Hi all! Hope you can help me interpret my chart from yesterday. I've had a Libre 3+ for about 5 days and it's been consistent and working well.
Background: prediabetic, A1C 5.7 for a few years, on metformin twice a day. Typically fast for 16-18 hours daily. Huge family history of T2D so I need to get a handle on this.
Yesterday: did a little experiment. Ate a fair amount of peanut brittle candy after a lunch of an In-nOut Burger protein style burger (ie no bun). 2pm
Huge spike to 160 about an hour later, highest I've seen yet. Cool, makes sense and goes (mostly) back down before dinner around 7:40 pm. Dinner is dumplings at Din Tai Fung (on vacation!) mostly protein, minimal carbs.
Took metformin as usual at 9:45pm. But looking at my graph this morning, had another rise around 3am, as high and wide as a regular non-sweets meal. Didn't wake up, didn't feel any of this.
Ideas for how to explain what's going on physiologically?
