Today I was given a blood glucose monitor tested before my eve meal and was 6.8 . Ate 2 mixed bean fajitas and went for walk 1 hour 15 mins . Tested after two hours and reading was 9.2 !
Don't understand why level so high..
You injected at the wrong time (e.g. you injected too late for the peak onset of the insulin to match the peak breakdown of your meal);
You miscalculated the carbohydrate contect of the meal (kidney beans, etc., all have carbs);
You were already on the rise from an unrecognised low sugar;
You've had some stress today, causing a bit of resistence;
You've injected into another site that has a different release ratio than where you're used to(or you've injected into an area that needs a few days off);
Erm, I'm sure there's more, but my grey-matter has just gone on strike!
I suggest:
Think about the above and whether there's any chance they may have been the cause;
Test again on the third hour post meal / injection and see what the result is then... and let us know
P.s. It helps if you let people know what insulin you're on... you could put it in your signature - like I do in my hall of infamy!
