Bob, rather than explain it fully here, I'd like to suggest that you pick up a book that will
explain these concepts. One of the books that does a credible job is "Pumping Insulin" by John Walsh
& Ruth Roberts. You don't HAVE to be a pumper to learn a lot of valuable DM management techniques
from that book.
Here is a brief explanation of the ratios:
When I count carbs for a meal, I already know how many carbs each unit of insulin will accommodate.
For example at breakfast, a unit will cover 9 carbs, so if I eat say, 36 carbs, I need to bolus 4
units. At supper, my ratio changes a bit to 1:11, so for every 11 carbs, I bolus a unit.
The drop ratio is how much my bg's drop for each unit given as a corrective bolus. During the
daytime, my correction (drop) ratio is
1:38, and in the wee hours it's about 1:22. So if my bg is say, 200 in the afternoon, I might take a
corrective bolus of 100/38= ~3 to bring me down to a target bg of 100. Make sense?
Since I pump, I can fine tune the quantity of insulin I take to the nearest 1/10 of a unit. I don't
calculate things in my head to a high degree of precision because it isn't generally necessary.
Let's say that I count the carbs for a meal and it comes out to 58. I round that to 60. Let's say my
actual ratio is 1:11. I'll round that to 10 and bolus 60/10 = 6 units. Trying to micro manage it any
closer than that isn't practical because a bit of activity or a difference in true carb intake
versus what's listed on food packages makes it fruitless to attempt perfection.
Hope this helps!

Find out what your insulin/carb ratio is.
Find out what your drop ratio is.
learn it. live it. live longer, and better.

What formula do you use to calculate your insulin requirement before
meals?
