The GI tract's response to disease is limited to just a few symptoms, regardless of underling pathology--nausea/vomiting, bloating/fullness, pain, constipation/diarrhea.
Loss of weight, tenderness, fever, bloody diarrhea however raise concern for inflammation of any cause, of which crohn's disease is one. Crohn's can however involve any part of the GI tract--from mouth to anus. Get checked if ?'s.
