snack, you dont understand the wiki article.
untill there are complications, its not considered a peptic ulcer. once the ulcer has developed complications ( bleeding, puncturing, leaking) then it becomes a peptic ulder.
and if your friend was bleeding after drinking from an ulcer, and did not die, chances are he is very uniqe as that is not normally the case.
once an ulcer goes peptic, you first start bleeding, then usually very quicly go to a puncture, and then to a leaking ulcer which is where the contents of the stomach leak out of the stomach into the internal organs.
once that happens, patient death is almost guarenteed without heroic measures ( such as organ transplants ) due to having bile and partially digested food dumped into the stomach cavity.
if in fact he was bleeding after drinking from an ulcer, and it never progressed passed that point, that is very rare and not normal.
