For the past few days, I've noticed undigested food in my stool. Should I be concerned?
Answer From John M. Wilkinson, M.D.
Occasionally, you may see undigested food fragments in stool. This usually is high-fiber vegetable matter, which normally isn't broken down and absorbed in your digestive tract.
Undigested food in stool isn't a problem unless it's accompanied by persistent diarrhea, weight loss or other changes in your bowel habits. If you have such signs and symptoms, consult your doctor.
