Hi, I just randomly got really nauseated and my stomach started to get bloated so I immediatly went to the bathroom to vent it and first brown bile came out then thick black blood looking stuff came out, a prettt good amount. Sorry for the gorry details, I'm just worried about it. I am on TPN and do not eat solid foods, or anything that would be thick and black, so if anyone has any ideas on what this could be I'd be very greatful for a responce. Just after I vented my tube my nausea and bloated subsided, so that's a good think. Thanks.
