Bile duct assumes bile storing role
Bile is major vehicle for excreting cholesterol from body
Bypassing natural gastric juices
requires longer feeding times and immobility of patient
Bypassing bodies natural defenses resulting in a greater risk of infection
Malabsorption
sterile or pasteurized feeding only
may result in abdominal pain and diarrhea
Bypassing esophagus, stomach, and duodenum
Missing key chemicals to break down food
proteases (protein)
