Why do I vomit when I have a bowel movement?

This question was asked in Independence, Kentucky on 04/03/2012.
Why do I get nauseated, dizzy, sweaty, cramps, and sometimes vomiting while trying to have a bowel movement? After I start going, it's like the flood gates open and, after I am done, it all goes away after I lay down for a few minutes.

This should be evaluated by a gastroenterologist. There are a number of reason why this may happen.
