Mechanism of diarrhea
Secretory
Osmotic
Altered motility
due to bacterial, viral and protozoal infection, increasing secretion of water and electrolytes
Secretory
large intestine is impaired
Secretory
could also be due to use of laxatives, hormones, neoplasm, and certain drugs
secretory
due to incomplete breakdown or reabsorption of food
Osmotic
consider tumor, maglinancies, intake of metformin
neoplasms
also known as maldigestion or malabsorption
Osmotic
Ex: Lactose intolerance, celia sprue, and poor absorption of sugars
Osmotic
receives almost completely digested food from the cecum, absorbs water and nutrients, and passes waste (stool or feces) to the rectum
Colon
seen in irritable bowel syndrome
altered motility
nerves and muscles of bowel are extra sensitive
Altered motility
can be bloating, increase flatus, diarrhea, or constipation
altered motility
most severe: presence of _
blood
and
pus cells
causes enterotoxin-producing organism
secretory
causes maldigestion
osmotic
active solutes remain in the lumen
osmotic
increased CHO in stool
Giardiasis
strongyloides
surgical procedures
Osmotic
Increased intestinal hypermotility
