Why Do I Have Pea-Sized Yellowish-Green bits in my Stool?

What Could Cause Small Pea-sized Yellowish/green Round Pieces In Stool?

I have small pea-sized round 'things' that are yellowish/green in my stool. This started a couple of months ago with chronic diarrhea. I have seen dozens—they have been biopsied and docs have no idea what they are. It doesn't look like any food I've eaten or any medication. I have already been tested for O&P—specifically Giardia—all negative. I've had a colonoscopy, fluoroscopy, endoscopy, abdomen ultrasound, pelvic ultrasound, small bowel follow-through, bloodwork, lower ct. All negative for anything abnormal. What could this be?


There may be several reasons that something like that could occur. The first being certain types of food that contain indigestible fibers. Those include popcorn, peas, corn etc. When they pass through they are not digested and are expelled in the feces.

It might help to start a food journal along with symptoms to see if they correlate to fatty meals or to a specific food you are eating.

Gallstones that are made of cholesterol can also be passed in the feces when they are small enough to make it through the bile and cystic ducts. Has your physician specifically checked for gallstones? Do you find your symptoms are worse after a fatty meal?

I would find it comforting to know that your other tests were all normal. That is definitely a good sign. That being said it is definitely worth starting the journal and asking your physician about the possibility of gallstones.
