Can pregnancy cause feces to be green?

No, pregnancy does not cause feces to be green. Green feces can be caused by a variety of factors, including consuming green leafy vegetables, iron supplements, bile duct obstruction, intestinal infection, celiac disease, cystic fibrosis, Crohn's disease, and food intolerances. If you are concerned about the color of your feces, it is best to talk to a doctor.
