Intestinal malabsorption
- Malabsorption: decreased absorption of fat and other nutrients caused by liver, biliary, pancreatic or intestinal disease. The 72-hour fecal fat determination is the best single test for mal- absorption.
- impaired absorption of nutrients in the gastrointestinal tract.
- A group of symptoms such as gas, bloating, abdominal pain, and diarrhea resulting from the body's inability to properly absorb nutrients.

Celiac disease
- disease occurring in children and adults characterized by sensitivity to gluten, with chronic inflammation and atrophy of the mucosa of the upper small intestine; manifestations include diarrhea, malabsorption, steatorrhea, and nutritional and vitamin deficiencies.

Tropical sprue
- chronic malabsorption syndrome occuring mainly in residents of or visitors to the tropics or subtropics; failed intestinal absorption of nutrients results in malnutrition and anemia due to folate deficiency.

Blind loop syndrome

Other and unspecified postsurgical nonabsorption

Pancreatic steatorrhea

Other specified intestinal malabsorption
- excessive amounts of fats in the feces, as in malabsorption syndromes.

Unspecified intestinal malabsorption
- Malabsorption: decreased absorption of fat and other nutrients caused by liver, biliary, pancreatic or intestinal disease. The 72-hour fecal fat determination is the best single test for mal- absorption.
- impaired absorption of nutrients in the gastrointestinal tract.
- A group of symptoms such as gas, bloating, abdominal pain, and diarrhea resulting from the body's inability to properly absorb nutrients.
