Can you become immune to insulin????

[Nadia Robertshaw]

I’m currently taking Levemir & NovoRapid....however I’m noticing at the moment that the NovoRapid seems to be having no effect on my sugars!

I have to take NovoRapid 15mins before I eat, I’m adjusting the amount of insulin depending on my glucose reading.

Can that happen?

Any information, & advice would be greatly appreciated. Thanks in advance

Your sensitive to insulin can definitely change. Are you carb counting as well as adjusting to the glucose reading? The other thing to think is whether you current batch of insulin is still within 28 days of being started and has been stored correctly as it can be less effective if not. If you’re in doubt about the current vial then starting a new one is a good idea. No effect may well be a dodgy vial. It depends on your readings as to what else might be suggested.

Since I’ve been under the hospital not been advised to carb count. I store all my insulin in the fridge, obviously the pens I’m using are not kept in the fridge. I have a pencil case I keep my daily supplies in. My test strips are all individually wrapped, & within date.

Your sensitive to insulin can definitely change.

Injection sites can also change things (mostly times rather than sensitivity, I think). Temperature changes things for many of us too (typically we need a bit less insulin when it's significantly warmer, so now it's cooler I'm needing a bit more insulin).

If you are not carb counting, how can you know if it’s the insulin that isn’t working - or if you are simply eating too many carbs to balance the doses you are taking?

It might be worth reducing the about of carbohydrate by a smallish amount and seeing what effect that has. You would need to be careful as insufficient carbs for the insulin dose could lead to hypoglycaemia, but if you measure the main carbs a ‘normal’ portion of a meal, I’d be interested to see what effect reducing the carb load by perhaps 20% had.

Sometime Insulin has been compromised before we re receive it . I have had to ditch a whole pack of Novorapid once .

Also See if you can persuade your DSN to teach you to carb count and adjust your doses properly. They should help you find out what your ratio is atm.

The only real help I had for adjusting my units for carbs eaten was from people on this forum and the BERTIE online course they directed me to
It is a course for T1 so if asked just tick T1
Their is an awful lot to it and our insulin ratios are usually higher than people with T1

Here's a simple introduction to carb counting:

It might be that your insulin has somehow become compromised. I would suggest using new insulin from a fresh batch to see if it makes any difference. Also check that your pens are working correctly 🙂

So...give us an example of where it hasn't worked as well, like what you were before and what you were later that has made you come to the conclusion that it isn't working
