I use libre, my last meal was 3.5 hours ago. Novarapid is the insulin, I gave a 1 unit correction and my blood sugar is now declining.. currently sat at 11.6 xHi @Chloelox, is it novorapid you took or a different insulin?
Did you eat recently? Is that why you are high? Is it less than 2 hours since you ate?
I use novorapid and if I'm still digesting a meal it can be a good hour or more before my blood sugars start coming down.
If I haven't eaten recently but am high for a different reason, it can be quicker before it starts coming down.
Do you use a libre/other CGM that you can keep an eye on?
Yeah I’ve done basal test, currently eating low carb but I let myself down and had a high carb meal for teatime, I injected for the meal but obviously not enough. I usually have between 0.1-0.5 ketones present. I’m never ketone free it seems.High blood glucose with ketones usually means lack of insulin. Have you tested your basal?
Hi guys,
my sugar is currently 16, 0.4ketones.
I have injected one unit as a correction dose 20 minutes ago and my sugar is still rising,
How long will it take for my correction to start working?
Thanks!
@TypeZero interesting on the rise after an injection. I am on Fiasp and have noticed a similar reaction.

I do and had done about 5 minutes before, thank you thoughPlease check high Libre readings with finger pricks.
Libre is renowned for inaccuracies above 10.
I am very sensitive, 1 unit dropped me from 16.3 (checked with finger stick) to 4.6 4 hours later with no food. I usually eat with correction but felt it wasn’t necessary and my sugars came down.What’s your correction factor? 1 unit doesn’t seem enough (in my opinion) unless you’re very very sensitive to insulin.
Libre is said to be up to 15 minutes behind actual blood glucose readings from a meter. Depending on the time of the day NovoRapid has a different onset of action, once I had to wait 1.5 hours for my blood sugar to come down before I could eat my breakfast.
However usually if I have eaten something then my blood sugar would start going down 1-1.5 hours after injecting (around the time when most if not all of the glucose from the food is released).
Without food, 20-30 minutes should start causing a drop in blood glucose.
I have realised something on Libre but I’m not sure if it’s 100% applicable to everyone, whenever I inject NovoRapid without food I can see that my blood sugar rises a little 0-1mmol before falling
Don't see it as letting yourself down @Chloelox , at least it gives you an idea of why your levels increased It's also great to learn from so it gives you a better idea how much insulin to have for the next time you decide to have a high carb meal!

I get the 1mmol night time insulin injections rise with my humulin I strangely and have had times where novorapid has increased my sugar before dropping prior to eating food.
