Cp values of Doritos (blue packet)

Just eaten ap a packet of doritos with a CP value of 2. Also had a BLT sandwich with a CP of 3. BG was 4.8 so took 10-1 units as my ratio was 2:1. My blood sugar 2 hours later is 14.9. I think the cp value of the doritos might not be right. Same thing happend to me last week. Has anyone else experienced this with doritos?

Welcome to the Forum.....

An average packet of Doritos (30g) is about 2 CPs, usually 17-18g CHO........so your count it correct......

High mid meal spikes means that the insulin action has not married up quite right with the digestion action..in this case your food has digested quicker than the insulin has processed it....

You next meal reading was probably on target if not near enough, was it?

You should consider injecting earlier....

When do you normally inject for your meals.......?

If you have experienced similar readings when Doritos have been on the menu its likely the Doritos may be slowing down the digestion of the meal, in comparison to your normal speed....

Have you done any other recent mid meal tests with other meals.....?

Thanks for the reply. I usually inject as I eat because I am on the novopen flexpen but being moved to the pump on Monday 4th Feb 2013. I have been watching my BG levels very rigorously the past couple of weeks in preparation for the switch to the pump.

Should I hold off then and see if the blood sugar does come back down in an hour or so or should I correct immediately. I suppose it might be good to watch and weight and learn from this.

You should not correct, as the dose is extremely likely to be correct, its just the timing of it that was out......

I am pumping now too, only for a week though, but the same rules still apply, you still need to think about giving your bolus dose before you eat, for me personally, 15 minutes minimum. Novorapid is marketed to take around 10-15 minutes to get going anyway, so for slower digested meals taking earlier than this will keep the spike down......

Again, its all trial and error, everyone is different, so just get a good few mid meal tests under your belt with varying pre meal injection times and see what happens.....i tend to stay in single figures is I take the insulin 30 minutes before I eat, not always possible though......

Left it to 3pm and BG was still rising to 15.9. I decided to correct with 8 units of QA. Just before my dinner there at 1845 my BG had only dropped to 14.6. I have taken my usual 1:1 ratio with +4 correction. Really strange that the 3pm correction had no effect whatsoever.

It is strange, I would of just kept going till dinner just to make sure the carb count was right.......the other possibility is your BI might be out......of course acting upon a few days results is the best way to do it as it may just be a one off.......

when did you last test your BI?
