Vomiting once every 48hrs. What could this be down to?

[portaloo]

DD 2.10yrs has been vomiting at 48hr intervals.
She is sick once, feels fine afterwards, then appears back to normal for 48hrs after which she vomits again.
She goes to nursery twice a week, but hasn't been for a week and a half now because every time I think she'll be going the next day, she vomits again.
She was due to go to nursery tomorrow morning, but she has been sick again in the last hour, so now obviously wont be going again.
Any idea what could be causing this?? Her diet hasn't changed btw.

Is it nerves about nursery? Dd2 can get so wound up (excitement or nervous) that she throws up.

Perhaps it's a food intolerance? Perhaps cut out dairy for a few days and see what occurs? Has she had an upset tummy before this 48hr vomiting? If so her tummy might still be feeling fragile and dairy can irriate it...

Is she having something like fruit juice or acidic fruit on a empty tummy? That can be too acidic and cause some people with sensitive tums to vomit ( then be right as rain)?

DeWe DD loves nursery and really looks forward to going, but has never been sick in anticipation of nursery before. In fact, apart from when she was a baby, this is the first time DD has been sick.
I shall keep an eye on when she is sick though.
Pancakeflipper I hadn't thought of that. Poor DD spent about 20 minutes before she vomited telling me she was hungry, yet refused any food. Now I realise she felt sick.
DD loves milk and cheese, and has had milk and yoghurt today, as well as a bite out of a strawberry and some ham and pasta. I will keep an eye on what she eats over the next few days, in case it happens again.
DD has had a runny nose and a cough, but they seem to be clearing up now.
Perhaps I should mention that DD has had no diarrhoea either.
Thanks for the replies. Much appreciated.

My 3 and a half son does this all the time, it's so frustrating and can go on for up to 10 days! He usually gets a really high temp which follows with him being sick then half an hour later he is fine and usually is fine for up to 48 hours sometimes 24 hours then high temp and sick, this can go on for days and he just drinks water no food etc. Towards the end he can eat + drink but still ends up with sudden high temps. He looses so much weight during these random sicknesses it's awful, but I just put it down to how his body handles illnesses!

luchap What do you do about nursery? Sounds horrible for you both.
DD has been fine since Thursday evening, when she was last sick, so fingers crossed.

My dd2 had this a few months ago when she was about 2.3. She vomitted at bedtime one night, then slept well and seemed fine the next day, then vomitted again during the following night.

When it had been going on for several days I rang the GPs and got a call back from our doctor. She said it is not unusual for toddlers to have a tummy bug that goes like this (I'd never heard of anything like it).

She said that as the vomitting is only happening now and then there was no danger of dehydration and that we should come in if it went on longer than 2 weeks. It stopped after 10 days.

Could be a food intolerance. Although children with a dairy intolerance tend to have loose bowels too.
Tummy migraine can cause vomiting.
Also constipation can cause vomiting too.

suiledonne That is helpful to know. I think if DD is sick again, then this will have been going on for 2 weeks so I'll see how she goes and if she's sick again, I'll be taking her to the Gp's.
She is fine up to half an hour before she is sick, then she is fine immediately after being sick for another 48 hours or just after.
This week, she was sick on Tuesday afternoon at about 2pm, then was fine afterwards until Thursday evening at approx 7pm. Since then she has been fine again, so am just keeping an eye on things.
purepurple No diarrhoea, and no constipation that I have noticed. What is tummy migraine? And what causes it?

Thanks for the link purepurple Very interesting.

Must confess I was thinking cyclic vomiting syndrome when I read the OP.

It's closely related to abdominal migraine but generally comes with more vomiting and less stomach pain.

Abdominal migraine is a bit more common though.

Either way, it doesn't sound like the bouts are long enough to need rehydration therapy but you should talk to your G.P. to get some tests done and discuss some medications that can reduce the frequency of the bouts.

DBennett Thank you for your advice. I think I will take DD to the Gp's just to be on the safe side. She doesn't appear to have much stomach pain before the sickness. I mean, she'll say she has tummy ache, but will carry on as normal IYSWIM. I'd expect her to be more upset if she had more than discomfort.
Thanks. So far, she has not been sick again since Thursday at approx 7pm so I'm waiting to see what happens this evening. Will book an appt first thing monday if she is sick again.

Going on 2 weeks of my 13 year old throwing up and then fine and will be for a couple days and then back at it again! Been to the doctor twice said it was a virus! My son will complain of stomach hurting and go to the restroom and then little while later he gets sick again! I'm so confused on what to do for him?????
