Question

Undigested food in stool: What does it mean?

For the past few days, I have noticed undigested food in my stool. Should I be concerned if this persists?

Answer

from Michael F. Picco, M.D.

Occasionally, you may see undigested food fragments in stool. This usually is high-fiber vegetable matter, which isn't digested by the enzymes in your digestive tract. Undigested food in stool generally 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.
