What Does It Mean When Your Poop is Green?
Medically reviewed by Andre Stone | MD, University of Pittsburgh School of Medicine on August 25th, 2026.
Green poop typically results from food choices, medications, or digestive changes and is usually harmless. The most common causes include eating leafy greens like spinach or kale, consuming foods with green food coloring, or taking iron supplements. Bile, which naturally gives stool its brown color, can remain green when food moves too quickly through your digestive tract. This rapid transit, occurring in conditions like diarrhea or irritable bowel syndrome, doesn't allow enough time for bile to break down completely. Green stool lasting more than a few days or accompanied by symptoms like abdominal pain, fever, or blood should prompt medical evaluation to rule out infections or other digestive issues.
