Type I and re-occuring vomiting

A couple of years back I was experiencing vomitting during the night (I'm T2). I'd wake up and literally have to sprint to the bathroom. Like you said - it came in waves.

There was never any indications that it was gonna happen, and I couldn't pin it on anything that I'd eaten or had to drink.

I never did get to the bottom of it - but it did stop eventually (touch wood)...

My son sometime wakes feeling nauseous and then begins vomiting. It usually passes by around mid-day when he can gradually begin eating normally.

We are confident we know why this is. It's because he's had an undetected hypo whilst sleeping.

Presumably, his liver has kicked out some glucose - which means his waking levels are pretty normal, but he feels lousy all day. I realised what was going on when I noticed it tended to happen on the morning following an active day (when he had PE/games). It also made sense to me that Glugagon injections tend to make the patient vomit - so I suppose the natural liver response is likely to do the same.

Now, we always turn his pump down a smidge overnight after an active day - and voila! It rarely happens.

I'm not saying this is the reason why other people feel sick/are sick in the night or morning, but it might be worth considering it as a possibility.

Thanks Sandra - that is VERY interesting.

Agree, that makes sense to me!

The next time you awaken feeling sick, just think through what your activity levels were for the whole of the preceding day (24 hours). Was it more than usual?

If this seems to be the case, why not do a night time b/m at 3am or 4am after especially active days to see if you are going low? After a few trials, you might even find when in the night this is happening - although I'm afraid we haven't pinned it down exactly - except that I think it is after 4am for my son.

Even if you don't have the flexibility of a pump, you could then perhaps have a bedtime snack (or bigger bedtime snack than normal) or slower-acting carbs etc, to try and avoid the hypo. Or maybe you could reduce your long acting insulin at bedtime?

I do know that my own findings are very much circumstantial - i.e. I have drawn my own conclusion about what is happening to my son. Nevertheless, I feel I must've found the answer for us because he was having days off school for the sickness quite regularly and now it is increasingly rare. I ask him now which type of sport he has done and we turn down the pump by either -10% or -20% for the whole of the rest of the day and night after the activity. Sometimes, this has not been entirely necessary and he's gone a bit high - but much better to do that once in a while than to have night-time hypos, me-thinks.
