i heard through a friend of mine that his cousin once spent a time in a drug rehab center and during his recovery time his intestines began to push backwards so that when he vomited, “poo” would come out his mouth. i didn’t think this was physically possible, but he insists it happened. can this be true, or is he just full of crap himself?
I worked on staff at a drug rehab center for four years and this is news to me. If this “gastrointestinal reversal” occurred, it wasn’t because of his rehab.
I dunno - a GI bleed with half-digested blood might appear to be excretement-like… but, again, that’s not inherent to the rehab process, that a Major Dysfunction of the body. Alcoholics experience these, I suppose other addicts could, too.
Some years ago a doctor friend of mine, when I asked her how were things going at the hospital, told me about a case as described on the OP, I was quite surprised, but too eeked to ask more.
Anecdotal and all that, so YMMV; but she wasn´t the kind of person that pulled stuff like that out of her (in this case) mouth; so if she said so, it must have been so.
And now I can´t take out of my head that scene in Austin Powers about the “coffee cup”…
Unless there is an anomalous erosion which creates a channel from the bowel to the stomach, people hardly ever vomit material from further down than the duodenum. And there’s nothing about detox that would change this.
I posted at length about the characteristics of human vomitus in response to a similar question a few months back. Feel free to search for said post.
