@Nodemus , from your other threads I take you're on insulin, plus you have recurrent pancreatitis attacks, is that right?
Medication and type of diabetes are essential information for a question like this. It would be helpful if you filled out your profile information or included the information in your questions.
As you can see, replies are vastly different depending on what type of diabetes the one replying has, and depending on the medication they use.
My sugars 9.7mmol fasting
Had microwave porridge and semi skimmed milk
2 hours later sugars 12.3
Is this ok or is porridge a no no?
So it looks like the porridge didn't raise you that much so the insulin seems to be working pretty well to deal with this meal.
But the baseline is on the high side at 9.7, and your meal pushed it higher.
What type of insulin do you use?
