High blood sugar all of a sudden

[Padders91]

Hi all, just recently I have found that my blood sugar levels has been going up in the 15 16s, even though I am eating the same things and carb counting on a 1:1 ratio, it's a bit puzzling, and irritating when I am doing things by the book so to speak, anyone else have days where there sugars just won't come down.

The odd day yes but if you are not ill and it goes on for longer you prob need to look at results and adjust your insulin ratios or basal.
