Why did you almost vomit before the colonoscopy? I've never had one, but I can see it happening in my near future sometime this year.
I vomited during the lead-up to an obstruction. I have not vomited since my resection in June 2010. Feel queasy sometimes but no puking.
To puke or not to puke is basically on the basis of where the disease is located. If it's located in the area of your stomache or esophagus then it can lead to puking. Also if it causes extream pain it can lead to nausia and vometting. It's like diarreah...if the disease is located in the colon it leads to diarreah, if the disease is mainly in the small intestine then they don;t suffer from diarreah as much.
