GI Tract Flashcards
**MNT for constipation
Adequate mix of soluble and insoluble fiber
Adequate fluid intake
Exercise
Soluble fiber
fruits veggies oats
forms a gel and slows down digestion
o good for watery diarrhea
insoluble fiber
bran wheat brans
absorbs water increases stool wegiht so speeds up time in small intestine - stumlats bowel mocement
**EXUDATIVE DIARRHEA characteristics
Mucosal damage - outpouring, mucous, fluid, blood
**EXUDATIVE DIARRHEA associated with
chrons disease
Ulcerative colitis
radiation enteritis
****osmotic diarrhea related to
solute that cant be absorbed
dumping syndrome
lactose intoleracne
releived by fasting
***secretory diarrhea
from bacterial exotoxin
c diff
viruses
increases intestinal hormone secrestions
***malabsorptive diarrhea
steatorrhea - excess fat
inflammatory bowel disease or bowel resection
not enough bile and pancreatic enzymes to digest
not getting the breakdown needed
**steatorrhea
excess fat n stool
60 g normal is 2-6 g
steatorrhea related to*****
lver disease
disease involvng distal ileum
BLIND LOOP SYNDROME
MNT for steatorrhea*****
MCT - synthetic fats
products absorbed witout bile salts
*****MNT for diarrhea
manage fluid and electrolyte - be careufl with dehydration
**minimal residue diet
insoluble fiber >20 g
*****MNT for diarrhea in chldren
replace Na and K losses
*** celiac disease gluten
specific peptide fraction of proteins - resistant to complete digestion by GI enzymes
Inflammatory bowel disease - CRONS DISEASE vs UC
Crons can eba naywhere along the GI TRACT
uc limited to large intestine and rectum
** inflamatory bowel disease etiology
inappropriate inflammatory response and ablity to suppress it
damage to the cells of the small / large intestine
malabsorption, ulceration, stricture
*****Energy requirements for IBD
energy requirements are constant unless weight gain desired
1.3-1.5 protein
bc of steroid use and protein losses from mucosa
divertculitis
bowel rest
short bowel syndrome - resection
b12 - intrinsic factor
*****!!! see nutrition for short bowel syndrome CHO FAT AND OXALATE
*** SMALL INTESTINE BACTERIAL OVERGROWTH SIVBO OR BLIND LOOP SYNDROME
overgrowth of bacteria
*** SMALL INTESTINE BACTERIAL OVERGROWTH SIVBO OR BLIND LOOP SYNDROME
consequences
B12 DEFICIENCY
