Vomiting after colonoscopy/endoscopy?

Just a question I hope someone here might be able to help with.  After months of being in bed sick, my 18 year old daughter had a colonoscopy, endoscopy and the camera capsule thing done on Wednesday.  No problems found anywhere except her colon which showed moderate to severe swelling and puss.  We are waiting on the labs and doctor appointment next week.  But since she had this done, she has not been able to keep down anything- not even ice chips.  This was outpatient and took less than an hour and was two days ago. I do have a call in for the doctor but it may be later today or tonight before I get them to call back.  Has anyone here had any experience with this?  She has been vomiting pretty regularly over the last few months and this is why we thought she may have ulcers in her stomach but none were found.  But this new upset stomach is within 20 minutes of drinking anyything it comes right up.
