text: if you eat too much do you throw up?   it's very likely although mostly, you'd just feel ill and stop eating (if you were smart, hopefully). in extreme cases, if you kept eating or were being forced to keep eating, it's also possible that your stomach could rupture or that your asophagus could swell up from the strain its being put on. either way, its not a pretty picture. i don't know if you've ever seen the movie se7en but.. yea. it's gross.
