Temporary lactose intolerance or ongoing bug?

[OopsieeDaisy]

DC was sick Saturday night and then seemed fine in themself all day Sunday, ate and drank although we didn’t give any milk/dairy. Monday, fine again all day but we reverted to their usual diet so milk on cereal, yoghurt, bit of cheese at lunch etc. Just approaching 48 hours clear, they were complaining of stomach ache and then vomited again. Then they were up a couple of times once in bed to be sick again a little bit. No diarrhoea, if anything they might be a bit constipated which is making me think maybe not lactose related?

We did have similar last time they had a sickness bug and literally vomited every 24 hours for about 5 days, but of course now I can’t remember what they ate as I just put it down to being a strange bug.

Just wondered whether anyone has experienced similar. My instinct now is to remove dairy again for a few days and hope it helps.

OP my son has just turned 12 months, at the start of the month he caught Norovirus from his nursery settling in days, the sickness only lasted a couple of days but the diarrhoea lasted over 10 days and he missed his first 2 full weeks of nursery. Out of desperation we tried him on a lacto-free diet and milk, which worked immediately. Did this for a few weeks, we've tried to wean him back, it went well when we were just introducing it back to his food, but we've started to switch back to normal milk/formula which had set off the diarrhoea yet again.

Everything I read warned the intollerance could last a couple of weeks tops, but it looks like our experience will be much longer.

It’s common to have temporary intolerances after a bug.

probiotics might help speed it up.

@Waitinggame42023 thank you for your reply and sorry to hear about your son’s intolerance - hopefully it resolves soon. His symptoms do sound very different to my DC but there is just something telling me my child’s isn’t still a bug at this point and I guess they are all affected differently!

@Octavia64 thank you - probiotics are a good idea, I’m going to look for some that would be suitable!
