Stool: Normally, foods are digested and nutrients are absorbed into the bloodstream mainly in the small intestine. Malabsorption may occur if a disorder interferes with the digestion of food or interferes directly with the absorption of nutrients. have your stool sample analysed by a lab to rule out parasitic infection. See you local Gastroenterologist for getting further testing done.
