- nonspecific
anorexia can be caused by
- side effect of medications, cancer, heart disease, kidney disease
emesis
forceful emptying of the stomach and interstitial contents

emseis is also know as
vomitting
emesis is usually proceeded by
nausea
vomiting without nausea is known as
projectile vomiting
projectile vomiting can be caused by
direct stimulation of the vomiting centre (tumors, aneurysms. .increase inter cranial pressure)
nausea
- subjective
- abnormal pain, spinning movements, hypersalvation, and tachycardia
consequences of nausea and vomiting
FLUID AND ELECTROLYTE IMBALANCES, ACID/BASE DISTURBANCES
- hyponatremia
- hypokalemia
- hypochloremia
- metabolic alkalosis
constipation
-difficult or infrequent bowel movements
- subjective (depends on normal bowel habits)
primary constipation is caused by
bowel dysfunction or evacuation
secondary constipation

acute diarrhea
- more than 3 loose stools developing within 24 hours and lasting less than 14 days
persistant diarrhea lasts
14 days to 2 weeks
large volume diarrhea
- volume of feces is increased
- generally caused by excessive amounts of water or secretions or both in the intestines
small volume diarrhea
- volume of feces is not increased
- usually results form excessive intestinal motility
osmotic diarrhea
- nonabsorbale substance in the intestine draws excess water into the intestine and produces large volume diarrhea
osmotic diarrhea causes
- lactase and pancreatic enzyme deficiency; excessive ingestion of synthetic nonabsorbable sugars, full strength tube-feeding formulas, dumping syndrome associate with gastric reaction
secretory diarrhea
excessive mucosal secretion of fluid and electrolytes produces large volume diarrhea
secretory diarrhea causes
infections (rotavirus), bacterial enterotoxins (coli, cholerae), exotoxins from overgrowth following antibiotic therapy (difficile)
small volume diarrhea is usually caused by
inflammatory disorder of the intestine (ulcerative colitis, chrons disease, microscopic colitis, colon cancer or fecal impaction
