Postprandial bG levels

I have just 'dug out' the results of an experiment I did to simulate postprandial bG levels in a lab using my own blood and that of a peer. The results in the chart are based upon my and a.n.other combined results. Looking at the chart and those of other groups doing the same experiment, the high appears at +45 mins, followed by a drop then a 2nd high at +90 minutes (not sure why) with the bG levels dropping to just above the starting level after +2 hours (which reflects my own testing experience). Although the quantities are small, I would expect a similar pattern with an infusion of a higher level of glucose.

Would this suggest that a 90-minute test is better than a 2-hour test?

Probably depends on what you are aiming for.
Does it matter to you that you what the peak is at 45 and 90 mins or is it more important to get down to a reasonable level. It probably depends on how high those peaks are. Is it better to have a +5 for 30 mins or a +2 for 4 hours.
Knowing all the info will help you to decide.

The results from this test probably depend on the food - how much, glycemic index and how the body reacts.

Yes, it was a 'crude' experiment outside the body, and, to that extent, somewhat artificial, although the individual inputs were from a diabetic and non-diabetic (allegedly!), both showing a similar result. If a 2nd peak at +90 were to be typical, even with a non-diabetic, then it begs the question 'measuring at +2 hours after when?' It was just an observation which I thought may be of interest. I don't think I'll be changing anything as a result.
 
It is certainly of interest and thanks for that.
One of the problems is that there isn't an easy relationship between food and BG level and until the establishment decides that it's possible to help control via diet I don't think there will be any studies done to give guidelines.

Probably helps to demonstrate that blood testing is an 'art' rather than a science. :D
 
I see the same kind of trend as you and share your conclusion. Yes the peaks matter. Why are people who spike into the teens after the point their 1st phase insulin response was supposed to do the job properly and 2nd phase still leaves them hovering around the point damage starts are left to deteriorate and those already diagnosed think they are fine.

Until their leg is amputated and all sorts like my great uncle before he died. :/
