Malabsorption is a state arising from abnormality in absorption of food nutrients across the gastrointestinal (GI) tract. Impairment can be of single or multiple nutrients depending on the abnormality.
Exocrine pancreatic insufficiency (EPI) is the inability to properly digest food due to a lack or reduction of digestive enzymes made by the pancreas.EPI can occur in humans and is prevalent in many conditions [1] such as cystic fibrosis, [2] Shwachman–Diamond syndrome, [3] different types of pancreatitis, [4] multiple types of diabetes mellitus (Type 1 and Type 2 diabetes), [5] advanced ...
Malabsorption is the inability to absorb food fully, mostly from disorders in the small bowel, but also due to maldigestion from diseases of the pancreas. Causes include: [ citation needed ] enzyme deficiencies or mucosal abnormality , as in food allergy and food intolerance , e.g. celiac disease (gluten intolerance), lactose intolerance ...
Without bile acids, this pathway would have a hard time occurring, which would lead to fat malabsorption and make steatorrhea more probable to occur. [2] Other features of fat malabsorption may also occur such as reduced bone density, difficulty with vision under low light levels, bleeding, bruising, and slow blood clotting times.
This is most often required due to Crohn's disease in adults and necrotising enterocolitis in young children. [2] Other causes include damage to the small intestine from other means and being born with an abnormally short intestine. [1] It usually does not develop until less than 2 m (6.6 ft) of the normally 6.1 m (20 ft) small intestine remains.
Patients with bacterial overgrowth typically develop symptoms which may include nausea, bloating, vomiting, diarrhea, malnutrition, weight loss, and malabsorption [2] by various mechanisms. The diagnosis of bacterial overgrowth is made by a number of techniques, with the gold standard [ 3 ] being an aspirate from the jejunum that grows in ...
Autoimmune enteropathy is a rare autoimmune disorder characterized by weight loss from malabsorption, severe and protracted diarrhea, and autoimmune damage to the intestinal mucosa. [1] Autoimmune enteropathy typically occurs in infants and younger children however, adult cases have been reported in literature. [9]
Fructose malabsorption is a digestive disorder in which absorption of fructose is impaired by deficient fructose carriers in the small intestine's enterocytes. [ citation needed ] Three autosomal recessive disorders impair fructose metabolism in liver cells .
