Some antibiotics use in pseudomembranous cololitis may cause green stool. In celiac disease severe gluten intolerance may cause green stool. Eating disorder like binge eating may cause green stool. Protozoa infection like giardia infection may ruled out. In stomach flue may cause green stool. More consuption of green leaf vegetables can cause green stool.
