Hi, Is this a regular thing or just now?
Apologise for the many questions but it would help to get a better rounded picture. Is there any more info you can give (possible current illness, length since diagnosis, possibility of honeymoon period, exercise today, any schemes following like daphne or carbohydrate counting or fixed doses, time since eve meal and what eaten and when injected incase your novorapid is still active from that). Novorapid can be active for 4hr+ so corrections should usually be avoided if you're within that time period after eating.
Have you tested for ketones? If ketones then keep up fluids. Have you sick day rules?
In the short term one night with higher blood glucose values is fine. You will obviously be better off contacting your diabetes team if this is happening more often. We can't give medical advice on here but can hopefully help stop any worry or concern. Again sorry for the many questions it just might help others with suggestions for example of what to ask your diabetes team. Hope you're well otherwise!
