What Does Green Poop Mean? Plus, Other Burning Poop Questions

Like it or not, everybody has to poop. It’s part of being human, but talking about it is embarrassing for some. Here’s the thing, though: Our poop — its color, shape, and even smell — can tell us a lot about our health.

So what does healthy poop look like? It would contain some fluids, undigested food (mostly in the form of fiber), bacteria, and dead cells that have been shed from the lining of your intestines. Ideally, stool should be well-formed, tube-shaped, and brown in color, though the hue varies from person to person.

While changes in poop’s color, consistency, frequency, and even smell can very well indicate a digestive problem, it can just as easily be a false alarm. “Sometimes it’s just something they ate,” says Edward Loftus, MD, a professor of gastroenterology at the Mayo Clinic in Rochester, Minnesota.

“You don’t want to react too much to one single change,” says Dr. Loftus. “But if it’s been going on for longer than a week and you don’t have a good explanation, you should tell your doctor about it.”
