My daughter has spins bifida and has had a small bowel obstruction in November. She was hospitalized and it eventually took care of itself. Recently she had s stomach virus that lingered. Her feces had no odor. She has been burping and it smelled like feces. We went to the dr, had an X-ray and has a hard stool. We have been treating her with laxatives. She is having bowel movements but are odorless but she is occasionally burping the terrible odor. What do you recommend?
