a simple example - Humalog
example constraints -- food has unknown carb content, but is
"standard" digestion time and not some high glycemic index stuff.
you start with bg = 100, eat and bolus for expected carb intake.
1 hour later bg = 250, expected = 150 (normal post prandial rise).
You would need insulin for the extra 100 points. This represents 40%
of the expected rise based on 20% per hour. There should be a
remaining 60% so an additional rise of 150 points is expected and
insulin will be needed to bring it down --- this would be beyond the
initial meal bolus which is working normally. Don't use this
technique without understanding it as the result will be CrAsH and
burn, or at least a little unexpected dip. Observe that the
calculation is again an approximation and is done in much the same
manner as unused insulin. The assumptions are that the food and
insulin curves MATCH. This is not always a good assumption. Examples
such as pizza, bolus must be extend a bunch, highly refined grains,
make you high quick, then you dip, etc....
