[|Human|] my brother was 4 wheeling and the 4 wheeler tipped over and it landed on his chest,he knows he has 2 broken ribs cause he had broken ribs before,this time he has pain around his stomach and he has black stools.The black stools went away but then he said he has it again.    thank you
[|AI|]  Hi, Welcome to Chat Doctor. I have read your query and understand your concern. Black stools, or galena, as we call them, is a sign of upper gastrointestinal tract bleeding. And as the black stools have started again, it means that the bleeding inside is still going on. So I would suggest that you show him to a Castro specialist and get his endoscopy done to identify and tackle the bleeding point. Till that time he needs to be started on a PPI tablet like pantoprazole or omeprazole, twice a day on empty stomach. Hope I have been helpful.
