Yes, insulin correction factor varies, you bet it! In my experience it may depend on time of the day, day of the month, month of the year, hours of sleep, previous hypos or hypers, general health, physical activity level, kind of food I am going to have for a meal… you name it. AND mine is generally twice/trice smaller than average. Well, actually, I found out that 'average' is a meaningless word in the T1 experience.
Me three and sometimes more if away from foodMy habit is 1 unit lowers it 2mmol/L.
It's quite common for the 1:3 ratio you quote to not work with higher BS levels.I was told that 1 unit of NovoRapid lower BS by 3mmol/L but I'm not sure that's the case, if I've over 10 then I defo need more then then a couple of units. Anyway it's all new to me at the moment so lets see.
Hi @SKB_9 The best way of checking your correction ratio is to keep a record and detailing in your diary of when you take it, what your bg reading was, how much was taken and what the following bg results were, ideally without taking any further insulin on board. Correction ratios are a personal thing so only you can work out what suits you. Your DSN would start you off on say 1 unit = 3 mmol/l which is a good starting point but would need adjusting in time.
Correction ratios are also reviewed on the DAFNE course so it’s good to get onto this course when you can.
Yes it can change. I have different correction factors for different times of the day (just as for carb ratios).
