What Causes Foul-Smelling Stool?

Often a change in diet is the reason that is given for smelly stools; malabsorption is also another common cause. Malabsorption happens when the body is unable to absorb the proper amount of nutrients from the food which you eat.

This generally happens when there is an intestinal infection which prevents your intestines from absorbing nutrients from food.

Common causes of malabsorption are:

  • Celiac disease—a reaction to the gluten damages the lining of small intestine which then prevents proper absorption of nutrients
  • inflammatory bowel disease—Crohn’s, for instance
  • carbohydrate intolerance–the inability to completely process the carbohydrates
  • Dairy protein and several other food allergies

A common symptom of the malabsorption is smelly stools.

If you have an inflammatory bowel disease, eating certain foods will lead to your intestines to be inflamed. People having the disorder normally complain of foul-smelling constipation.
