Do competitive eaters vomit afterwards?

I just watched a brat eating contest on ESPN2, and the winner downed something like 60 brats in 10 minutes. Opposed to such events or not, do these people go and chuck up all that food when they’re done? It would seem dangerous not to get rid of a few pounds of sausage if you could even manage. I just can’t imagine not spewing them back out.

I think I read fairly recently something about Kobayashi throwing up after a win, but can’t provide a cite.

No cites, but there was one competition on TV in Japan recently where one of the competitors looked very much much like she was bulimic. All the competitors were thin, but she was skeletal (the others just looked like ordinary people). Plus, she was missing many of her teeth (she got knocked out of the contest when they got to a food that had to be chewed thoroughly), which could have been the result of frequent vomiting.
