Just come back from a very active holiday where temps were about 35c on average, my levels would not go below 11 no matter what I tried, walking, eating less carbs cranking up the insulin just makes it plummet temporarily before a natural spike again. I've even changed pens a few times in case they went bad in the heat.
Oh wow I thought that it was just my bad diabetic management! I always thought that you would have more hypos in the heat. My BG’s in the morning have been terrible morning, this morning they were 19 and like others took more corrections than I usually feel safe to do so. I had just had enough of not going below 10 too. Finally before lunch today they were 5.2.
