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.
Causes
Common causes of steatorrhea
- Celiac disease
- Choledocholithiasis
- Cystic fibrosis
- Exocrine pancreatic insufficiency
- Hypolipidemic drugs
- Inflammatory bowel disease
- 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.

Causes in Alphabetical Order
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,[1][2][3][4]
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.[2][4]
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.[1][3]
Natural Fats
Consuming Jojoba oil has been documented to cause steatorrhea and anal leakage because it is indigestible.[5] 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.

While the Food and Drug Administration (FDA) still must approve the switch, the agency often follows the advice of its experts. If it does, Orlistat (xenical) -- currently sold only by prescription -- could be available over-the-counter (OTC) later this year. But it's important to know that the weight loss that's typical for users of the drug -- 5 to 10 percent of total weight -- will be less than many dieters expect. And many consumers may be put off by the drug's significant gastrointestinal side effects, including flatulence, diarrhea and anal leakage.

The Frito-Lay report states: "The anal oil leakage symptoms were observed in this study (3 to 9% incidence range above background), as well as other changes in elimination. ... Underwear spotting was statistically significant in one of two low level consumer groups at a 5% incidence above background." Despite those problems, the authors of the report concluded that olestra-containing snacks "should have a high potential for acceptance in the marketplace."

GlaxoSmithKline has a tip for people who decide to try Alli, the over-the-counter weight-loss drug it is launching with a multimillion-dollar advertising blitz—keep an extra pair of pants handy. That's because Alli, a lower-dose version of the prescription drug Xenical, could (cue the late-night talk-show hosts) make you soil your pants. But while Alli's most troublesome side effect, anal leakage, is sure to be good for a few laughs, millions of people who are desperate to take off weight may still decide the threat of an accident is worth it.

Olestra sometimes causes underwear staining associated with "anal leakage." Olestra sometimes causes underwear staining. That phenomenon may be caused most commonly by greasy, hard-to-wipe-off fecal matter, but occasionally also from anal leakage (leakage of liquid olestra through the anal sphincter).
