IBS
irritable bowel syndrome
R/O
Rule out
stat
immediately
Antacids
Counteract or neutralize acidity, usually in the stomach
Antacid drugs
calcium carbonate
Antidiarrheals
Control loose stools and relieve diarrhea by absorbing excess water in the bowel or slowing peristalsis in the intestinal tract
Antidiarrheal drugs
loperamide, kaolin/pectin
antiemetics
controls nausea and vomiting by blocking nerve impulses to the vomiting center of the brain
antispasmodics
decrease gastrointestinal (GI) spasms by slowing peristalsis and motility throughout the GI tract
antiemetic drugs
prochlorperazine, ondansetron
antispasmodic drugs
glycopyrrolate, dicyclomine
laxatives
treat constipation by increasing peristaltic activity in the large intestine or increasing water and electrolyte secretion into the bowel to induce defecation
laxative drugs
senna/sennosides, psyllium
abdominal
ultrasound visualization of the abdominal aorta, liver, gallbladder, bile ducts, pancreas, kidneys, uterus, and bladder
ultrasonography (US)
high frequency sound waves are directed at soft tissue and reflected as “echoes” to produce an image on a monitor of an internal body structure
lower gastrointestinal series
radiographic images of the rectum and colon following administration of barium into the rectum
computed tomography (CT)
imaging technique achieved by rotating an x-ray emitter around the area to be scanned and measuring the intensity of transmitted rays from different angles
stool culture
test to identify microorganisms or parasites present in feces that are causing a gastrointestinal infection
colostomy
creation of an opening of a portion of the colon through the abdominal wall to its outside surface in order to divert fecal flow to a colostomy bag
lithotripsy
procedure for crushing a stone by eliminating its fragments surgically or using ultrasonic shock waves
gastrointestinal endoscopy
visual examination of the gastrointestinal tract using flexible fiberoptic instrument with a magnifying lens and a light source to identify abnormalities, including bleeding, ulcerations, and tumors
hepatitis panel
panel of blood tests that identifies the specific virus- hepatitis A, hepatitis B, or hepatitis C- that is causing hepatitis by testing serum using antibodies to each of these antigens
liver function tests
group of blood tests that evaluate liver injury, liver function, and conditions commonly associated with the biliary tract
bariatric surgery
group of procedures that treat morbid obesity, a condition that arises from severe accumulation of excess weight as fatty tissue, and the resultant health promblems
anastomosis
surgical joining of two ducts, vessels, or bowel segments to allow flow from one to another
steatorrhea
passage of fat in large amounts in the feces due to failure to digest and absorb it
peristalsis
progressive, wavelike movement that occurs involuntary in hallow tubes of the body, especially the GI tract
flatus
gas in the GI tract; expelling of air from a body orifice, especially the anus
