Malabsoprtion

• Small bowel vs Large bowel
• Short bowel syndrome - not much bowel left to absorb
• Gall bladder removed - liver empties directly into duodenum, if you eat a huge fatty meal, the liver can’t keep up with enough bile and fat goes by unprepared for absorption….poop out fat
• Disacharidase insufficiency - ex is lactose intolerance
• Lymph obstruction
• Infection of cells of SI or LI - ex is Tropical Sprue
• Excess laxatives
• Some things are global malabsorption, some are just one (think lactose or fat)
• Steatorrhea - fatty stool, common in people w/ cholecystectomy that eats fatty meal, stool floats even after a few minutes
• Need to eat less fat at servings
• Lactose intolerance - eliminated lactose or take an enzyme or take in prepared lactose
