Hypo advice

Hi, I have had type one diabetes for 16 years and have never experienced this before. In the last few days I have had hypos around one hour after lunch. Usually I can correct with 15g fast acting carbs and be fine again within 15 minutes. However these hypos are refusing to budge for around two hours. Staying around the 3-3.5mmol/l mark despite multiple corrections. After a couple of hours it’s like all the carbs suddenly kick in and I’m shooting up to 18mmol/l.

I’ve just adjusted my lunchtime carb ratio and basal rates for tomorrow as I’d rather run the risk of running a little high than have this again. I feel terrible now!

@Harriet90 have you changed what you are eating at lunchtime?
It could be that you are eating something that is taking longer to digest (fatty foods like pizza are the classic guilty parties for this) so the carb absorption peak is delayed behind the insulin potency peak.
Unfortunately, different foods are absorbed at different rates but our fast acting insulin works at the same speed regardless of what we eat.
One way to overcome this is to carb count and use the normal carb ratio but split your dose. For example, take 50% before you eat and the other 50% 90 minutes or two hours later.

Hi Helen,
Thanks for your reply, I haven’t changed what I’m eating but I did have a baby a few months ago which has played havoc with a few things due to hormones I assume. Potentially it could be down to that? I’ve just never had hypos that have taken so long to correct but will try splitting my dose tomorrow to see if that helps. Thanks
