My last three bowel movements have actually been green.


I searched your site for an answer to my particular problem, but frankly, have seen or heard of nothing similar.

My last three bowel movements (over 3 days) have actually been green. I can’t think of anything unusual I have eaten or any changes in my diet that may have caused this. I feel fine otherwise and have no GI (gastrointestinal) discomfort at all. Only this strange color change.

Do you think this is a problem? What might be the cause? Is this worth a trip to the doctor or merely a wait and see kind of thing?

Please advise if possible. Thank you.

Have you been eating different foods for the last 3 days? Iron supplements and meat turns stool black.

Bile is produced by your liver and stored in your gallbladder. Bile is green and secreted into your intestines to emulsify fats so they can be digested by enzymes and absorbed into your blood. Bile should not be excreted in stool and is generally reduced by the time stool reaches your large bowel.

Unless you have other symptoms like pain under your rib cage that radiates around to your back, I would wait 3 or 4 more days. If you have abdominal pain, I would recommend calling your doctor immediately. Otherwise, if the green color continues, I would recommend making an appointment with your doctor to get it checked out in a few days.
