From the Guidelines
Steatorrhea is best managed with pancreatic enzyme replacement therapy (PERT) and dietary modifications, including a low-fat diet and supplementation with fat-soluble vitamins, as evidenced by the most recent and highest quality study 1.
Causes and Treatment of Steatorrhea
Steatorrhea is a condition characterized by excess fat in the stool, resulting in pale, foul-smelling, greasy stools that may float in the toilet. It occurs when the body cannot properly digest or absorb fats from food. Treatment depends on the underlying cause, which commonly includes pancreatic insufficiency, celiac disease, or other malabsorption disorders.
- For pancreatic insufficiency, pancreatic enzyme replacement therapy (PERT) such as Creon or Zenpep is recommended, typically taken with meals at doses of 500-2,500 lipase units per kg per meal, adjusted based on response 2.
- For celiac disease, a strict gluten-free diet is essential.
- Other treatments may include medium-chain triglyceride supplements, fat-soluble vitamin supplementation (vitamins A, D, E, and K), and addressing any underlying conditions like chronic pancreatitis or inflammatory bowel disease.
Importance of Early Identification and Treatment
The management of steatorrhea with pancreatic enzyme replacement therapy is the mainstay of nutritional management, and early identification and treatment is key 1. The presence of steatorrhea, coupled with poor dietary intake, renders patients at considerable risk for undernutrition, muscle depletion, and fat-soluble vitamin deficiency.
Dietary Modifications and Supplementation
Patients should monitor their stool appearance and consistency, maintain adequate hydration, and follow a low-fat diet if recommended by their healthcare provider. A diet rich in carbohydrates and protein, with 30% of calories initially given as fat, is well tolerated 2. Fat-soluble vitamins (vitamin A, D, E, K) as well as other micronutrients should be supplemented if clinical deficit is apparent.

From the Research
Definition and Causes of Steatorrhea
- Steatorrhea is a condition characterized by excessive fat in the feces, often resulting from malabsorption of fat [(3, 4, 5)].
- It can be caused by various conditions, including pancreatic diseases (e.g., chronic pancreatitis, cystic fibrosis, pancreatic cancer), extrapancreatic diseases (e.g., celiac disease, Crohn's disease), and gastrointestinal and pancreatic surgical resections 3.
Diagnosis of Steatorrhea
- Several indirect parameters and quantitative measures of fecal fat excretion can be used to diagnose steatorrhea, including fecal weight, fecal aspect, microscopy, steatocrit, serum beta-carotinoids, and titrimetric and gravimetric analysis 6.
- Other diagnostic methods include 14CO2-breath tests, NMR-spectroscopy, near infrared spectrometric analysis (NIRA), and 13CO2 stable isotope breath tests for fat maldigestion and absorption 6.
Treatment of Steatorrhea
- Pancreatic enzyme replacement therapy (PERT) is a common treatment for steatorrhea, aiming to provide sufficient active lipase in the duodenal lumen to improve fat digestion [(3, 4, 5, 7)].
- Enteric-coated, delayed-release pancrelipase capsules (e.g., Minimicrospheres) are an effective treatment for steatorrhea associated with pancreatic insufficiency in patients with cystic fibrosis 5.
- PERT with delayed-release pancrelipase can improve coefficients of fat and nitrogen absorption, as well as clinical symptoms, without serious treatment-emergent adverse events 7.
