Carbs counting question

[PaulinaB]

Hi all!

I just started carbs counting and I'm still trying to figure out what my insulin-carbs ratio should be.
My question: if I know that 1 unit of insulin lowers my BG by 1.4mmol - can I somehow calculate my insulin-carbs ratio from that?

I'd like to think it was that logical, but I'm afraid it isn't. You could start by seeing how much a fixed amount of carbs raised your BG, but even that is hit and miss does to the GI, and individual's reaction to different foods.

When I started taking insulin, I'd already been carb counting for a long time, and started on a fairly low level ratio. That way you lessen hypo risk. Then I refined it in the light of experience.

Not much help eh?

Cheers
Barry

After I gave it more thought I kind of figured out that it's not that simple Thanks anyway!

The only way to figure it out is by testing before and 2 hrs after eating. You need to keep a detailed diary of readings, including amount of carbs eaten. Eventually, you'll begin to see patterns. Your insulin/ carb ratio is also dynamic, it can and will change often. Many have a different ratio for breakfast and evening meal for instance or if been to the gym. At best, we're estimating but it's important to keep records to make that estimation as close as possible.
