I was well taught and prepared as to how to treat a hypo but knew nothing if I were to take insulin as usual or skip it since it was lunch time.
I can understand your dilemma.
The reply from
@Lucyr at post #16 is very valid, but perhaps a little hard. You started this thread asking for advice, after the event and I think that was a good call by you. My first hypo was horrible and while I tried to work out 'why', my DSN later just told me they 'happen' , treat and move on; and I remember thinking 'but what's the answer to why....'. I hadn't found this forum at that time. My circumstances were rather different in those early days.
I hope you've now got a better feel for how to manage your next hypo, alas there will be a next!
Hypos are horrible, at first frightening, but manageable and less frightening once you realise they generally DON'T kill you. The incidence of that is extremely small, in practice. The short term problems that can arise are broadly two-fold:
repeated frequent hypos can lead to a loss of hypo awareness;
and over-responding with too many dextrose tabs or JBs etc, can start you onto the 'roller coaster' of low/ too high/ back to hypo.
In the longer term hypos can be damaging to you, which is also a good enough reason to avoid them!
I still don't have a specific answer to the nub of your original question. Yes, take insulin with your next meal (lunch in this case). But how much? You are still on fixed doses and not yet carb counting; and how much hypo response had you taken - ie what accumulation of carbs was now in your system? Rhetorical question, since you aren't carb counting. How big was your lunch going to be? Would your fixed dose normally match your normal lunch? More rhetorical questions. You need to ask your DSN.
After a hypo, after the initial treatment and initial recovery, I take some more lower GI carbs about 15+ mins later (eg a biscuit of 6-12 gms) to consolidate the recovery. However if it were my due lunch time, I'd eat that as planned. But how much bolus would depend entirely on: how deep had the hypo and response been; how big the lunch was going to be and hence how much my bolus would have been; then adjust by either reducing my bolus by a couple of units or having a supplement to my lunch. For me, if only finger pricking was available, this would be a trial and error lesson. Today, because I have Libre I can monitor simply and painlessly and adjust my lunch strategy accordingly; but that is no help to you just now!
Please don't be put off asking questions. How else do we learn?
