My 16 year old son got his J pouch 4 weeks ago. Today he is experiencing mild nausea for the first time since he had a blockage at the hospital last month, and he's in bed, which he doesn't do unless he feels really bad. I'm a bit worried that it could be another blockage, but he hasn't vomited. He did eat corn on the cob and had some nuts on his dessert last night. (I know, not recommended foods!) Could the corn and nuts cause nausea? He's still having BMs today.
