so tonight I went round to a friends house and she did pizza for dinner (frozen deep pan)...I usually do my own Wholemeal one and my blood sugars are fine. So I tested my blood after an hour and 20 mins: 7.2 mmol Then 2 hrs it went up to 8.6mmol. Then 2hr 40 mins my blood sugar was down to 5.1. Have I caused a load of damage? I have tested other family and friends who aren’t diabetic and perfectly healthy and even their blood has been an 8 the odd time after things like pizza and pasta.
