Summary
Malabsorption syndromes occur when nutrients are not effectively absorbed in the small intestine, leading to various symptoms and deficiencies, and can be broadly categorized into digestive disorders and absorption defects.
Key Points
- Malabsorption syndromes result in nutrients lingering in the gastrointestinal lumen, disrupting stool formation and leading to diarrhea, bloating, flatulence, unintentional weight loss, and nutritional deficiencies.
- Fat malabsorption, known as steatorrhea, is characterized by fatty, greasy, floating, voluminous, and foul-smelling stools, and is associated with deficiencies in fat-soluble vitamins A, D, E, and K.
- Protein or carbohydrate malabsorption typically causes watery diarrhea due to water being drawn into the lumen, while protein loss can also lead to edema.
- Digestive disorders causing malabsorption include exocrine pancreatic insufficiency (lack of digestive enzymes), cholestasis (impaired bile flow), and lactose intolerance (inability to digest lactose).
- Exocrine pancreatic insufficiency, often caused by chronic pancreatitis (especially from alcohol abuse in adults or cystic fibrosis in children), leads to global malabsorption due to insufficient pancreatic enzymes.
- Cholestasis, whether hepatocellular or obstructive, impairs bile flow to the intestine, hindering fat digestion and absorption, and can result in clay-colored stools and jaundice.
- Lactose intolerance is caused by decreased lactase activity, leading to fermentation of lactose by gut microbes, producing gas, bloating, and diarrhea.
- Absorption defects damage the small intestine mucosa, reducing the surface area for nutrient absorption, and include conditions like celiac disease, tropical sprue, and Whipple's disease.
- Celiac disease is an autoimmune disorder triggered by gluten, causing inflammation and damage to the small intestinal villi, diagnosed by specific antibodies and confirmed by biopsy showing villous atrophy.
- Tropical sprue and Whipple's disease are infectious causes of global malabsorption, with tropical sprue linked to bacterial overgrowth in tropical regions and Whipple's disease caused by Tropheryma whipplei, affecting joints and potentially the CNS and heart.
