Hi, I just started a trial of the libre 2. My blood glucose is currently sitting at 2.9. this seems very low to me. I was told I was prediabetic in July (42--so not terribly high) and I've been lowish carb med ever since and reduced to 39. I also lost just under a stone going from BMI of 21.5 to 19.7. I plan to relax a bit with my diet over Christmas as I've been fairly hardcore. I'm approaching it like an experiment so today I started using a libre 2. My reading was 4.2 before lunch. Two hours after lunch it dropped to 3.9 and then 2.9 where it's sitting just now. What's happening? For lunch I had two boiled eggs, a slice of luvtoliv bread and real butter, whole fat greek yoghurt, a pear, flaxseed and maybe 7 almonds. I generally feel tired after eating but this isn't as marked since cutting the carbs, especially refined and white carbs (no rice, potatoes, pasta etc) do I have reactive hypoglycemia? What's going on?
