Undigested food in stool: What does it mean?

Medically reviewed by Drugs.com. Last updated on Feb 16, 2022.

Sometimes, you may see undigested food fragments in stool. This usually is high-fiber vegetable matter, which usually isn't broken down and absorbed in your digestive tract. At times, undigested food is a sign of poor chewing and fast eating. Make sure that you chew your food well.

Undigested food in stool isn't a problem unless it occurs with lasting diarrhea, weight loss or other changes in your bowel habits. If you have such signs and symptoms, talk to your health care provider.
