==Overview==
==Overview==
A medical condition that is characterized by passing of stools that contain a high amount of fat. This condition usually arises when the small intestine becomes unable to properly absorb fats that enter the system through foods. People affected with Steatorrhea pass excessive amounts of fat from their body along with stools. This is accompanied by an oily discharge from the anus.
Steatorrhea may be caused by [[Celiac disease]], [[choledocholithiasis]], [[cystic fibrosis]], [[exocrine pancreatic insufficiency]], [[hypolipidemic drugs]], [[inflammatory bowel disease]], [[Small intestinal bacterial overgrowth syndrome|small bowel bacterial overgrowth syndrome]].

Causes of steatorrhea can be due to side effects from food or medication as well as possible biological causes. Biological causes can be a lack of [[bile]] acids (due to liver damage or hypolipidemic drugs), defects in pancreatic juices (enzymes), and defective mucosal cells. The absence of bile acids will cause the feces to turn gray or pale.

===Side Effect Causes===
Steatorrhea can also be due to eating non-digestible oils or fats such as [[Olestra]], and a side-effect of medicines that prevent the absorption of dietary fats such as [[Orlistat]],<ref name=WP>{{cite news |first= |last= |authorlink= |coauthors= |title=Weighing a Pill For Weight Loss |url=http://www.washingtonpost.com/wp-dyn/content/article/2006/01/23/AR2006012301270.html |quote=While the Food and Drug Administration (FDA) still must approve the switch, the agency often follows the advice of its experts.

====Artificial Fats====
The fat substitute [[Olestra]], used in some reduced-fat foods, has been proven to cause leakage in some consumers. The United States [[Food and Drug Administration]] warning indicated that excessive consumption of Olestra could result in "loose stools"; this warning has not been required since 2003.<ref name=CSPI/><ref name=CSPI2> {{cite news |first= |last= |authorlink= |coauthors= |title=Reported medical side-effects of Olestra according to Procter and Gamble studies |url=http://www.cspinet.org/olestra/11cons.html |quote=Olestra sometimes causes underwear staining associated with "anal leakage."

====Medications====
[[Orlistat]] (Xenical) is a diet pill that works by blocking the enzymes that digest fat. As a result fat cannot be absorbed from the gut and some fat is excreted in the feces instead of being metabolically digested, sometimes causing oily anal leakage.<ref name=WP/><ref name=NW/>
====Natural Fats====
Consuming Jojoba oil has been documented to cause steatorrhea and anal leakage because it is indigestible.<ref>[http://ajpregu.physiology.org/cgi/content/abstract/263/3/R464 Comparative aspects of lipid digestion and absorption: physiological correlates of wax ester digestion]</ref>
Consuming escolar and oilfish (sometimes called butterfish) will often cause steatorrhea. The fish is commonly used in party catering due to its delicate flavor and the fact that it is cheap and readily available.
