When patients are diagnosed with fat malabsorption, they are often noted to lose weight in spite of adequate intake of food. Chronic diarrhea has been noted as the most common symptom in the evaluation of these patients. These patients will also have steatorrhea, which is nothing but a fatty stool. It is the hallmark symptom of malabsorption syndrome. These stools are foul-smelling, pale, bulky, and greasy in appearance.
