If your ratio was one unit of insulin to every ten grams of cabs (1:10) then had to add on an extra two units of insulin what insulin to carb (i:c) ratio would this be please?

Also would like to know this for marking down as a diary entry.

Thank in advance for any replies Smile x

Hi Whiskysmum,
The ratio is simply the proportion of QA you need to cover each CP (10g) to keep you BG in target.
If you need to 'add on' insulin, do you mean for when your BG is high? That's what we mean by a 'correction' (thinking that 1u may reduce your high BG by 2-3mmol/l)
So to record in your diary for example for 30g (3CPs) on a 1:1 ratio, you'd put 3 (CPs), 3u QA. But any correction for high BG you'd record as a + in QA dairy row. If 2u correction, it'd be 3+2

Hi Carolin,

No it's not for a correction. It's for my teatime dose. I've been doing 1u QA of insilin for every 10g (10CPs) carbs so if I've had 40g (4CPs) carbs then I would inject 4u QA. I'm now doing (for my new dosage) 4u QA plus an extra 2u QA so 6u QA so what would a ratio of 6u be for 40g (4CPs)?

based on your example your ratio would be 1.5:1 so for every 1cp you would take 1.5 units of QA insulin.

I think for most DAFNE graduates they will take a incremental approach to dose adjustment.

If 1:1 (1:10) is not enough for you then you would increase that to 1.5:1 (1.5:10), this makes its easier to calculate more achievable insulin dosages, however some people do need to get there ratio to a more accurate number eg 1.25:1, 1.75:1.

Any more precise than that and it becomes difficult to dose properly unless your on a pump.

If several days results show you need more, increase by .5 units to every 10 grams.... Wink
