leakage because it is indigestible. Consuming escolar and oilfish (sometimes mislabelled as butterfish) will often cause steatorrhea, also referred to as Gempylotoxism or Gempylid Fish Poisoning or keriorrhea. Artificial fats The fat substitute Olestra, used to reduce digestible fat in some foods, was reported to cause leakage in some consumers during the test-marketing phase. As a result, the product was reformulated before general release to a hydrogenated form that is not liquid at physiologic temperature. The U.S. Food and Drug Administration warning indicated excessive consumption of Olestra could result in "loose stools"; however, this warning has not been required since 2003. Diagnosis Steatorrhea should be suspected when the stools are bulky, floating and foul-smelling. Specific tests are needed to confirm that these properties are in fact due to excessive levels of fat. Fats in feces can be measured over a defined time (often five days). Other tests include the (13)C-mixed triglycerides test and fecal elastase, to detect possible fat maldigestion due to exocrine pancreatic insufficiency, or various specific tests to detect other causes of malabsorption such as celiac disease. Treatment Treatments are mainly correction of the underlying cause, as well as digestive enzyme supplements.
