GI Disorders Flashcards
PUD
Peptic ulcer dz
S/S of pernicious Anemia
SOB, fatigue, weakness
Glossitis
Parasthesias
GERD is due to
reflux of HCL from the stomach into the esophagus
Symptoms of GERD may include
heartburn, epigastric pain, or coughing within 1 hour after eating
S/S of GERD worsen with:
lying down, ETOH, coffee, smoking
Relatively uncommon disorder almost always associate with GERD
Barrett’s esophagus
Barrett’s esophagus is characterized by:
dysplastic regions within the esophagus
Herniation of the stomach through the diaphragm
Hiatal Hernia
Inflammation that affects gastric mucosa that can cause erosions
Gastritis
S/S of Gastritis
pain or burning, occasionally bleeding
Bleeding from gastritis is AKA
acute hemorrhagic gastritis
___usually results from overuse of NSAIDs or ETOH
acute gastritis
NSAIDs suppress:
protective prostaglandins
Acute gastritis is resolved by:
removal of the offending agent
___ gastritis is thought to babe autoimmune, and mainly occurs in the elderly
Chronic gastritis
Chronic gastritis causes ____ of the gastric mucosa
atrophy
PTs with chronic gastritis often develop ___ due to the loss of intrinsic factor
pernicious anemia
5 anatomic sections of the GI tract
Epigastric RUQ RLQ LUQ LLQ
Passing a scope into the GI tract for direct visualization
Endoscopy
Visualization of the esophagus, stomach, and duodenum
Esophagogastroduodenoscopy
Visualization of the rectum, colon, and distal small bowel
colonoscopy
Test to detect small, hidden amounts of blood in stool
hemoccult test
Hemoccult test is used to screen for:
colon cancer & causes of gastric bleeding (PUD)
___ referes to pepsin + hydrochloric acid
Peptic acid
___ digests food in the stomach and duodenum
peptic acid
PUD is a chronic inflammatory condition of ___
stomach and proximal duodenum
PUD can cause ____ due to acid disturbing the underlying tissues of the stomach and duodenum
gastric/duodenal ulcers
Mucosal disturbance is caused by ____
aggressive change factors
Chronic steroid use can disturb the mucosal lining of the stomach due to:
decreased synthesis of prostaglandins which protect the stomach lining
Most PTs diagnosed with PUD are also positive for an organism called:
H. pylori
PUD is treated by:
antacids, H2-blockers, proton pump inhibitors, & eradication of H. pylori with antibiotics
Number 3 killer amongst all cancers
colorectal cancer
Colorectal cancer almost always arises from ___
Preexisting benign neoplasms in the form of polyps
Risk factors for colorectal cancer:
Age > 50
high fat diet, obesity, sedentary lifestyle
Smoking & ETOH overconsumption
Family HX
S/S of colorectal cancer
blood in stool
change in bowel habits
Best Tx for colorectal cancer
high-fiber diet & lifestyle changes
Chronic disorder characterized by inflammation of the lining/walls of the intestines
Inflammatory bowel disease
2 main types of IBD
Crohn’s & ulcerative colitis
Inflammation in IBD causes:
bloody diarrhea & abdominal cramps
Possible causes if IBD include:
infectious agents
Links to familial occurrence
Autoimmune response
Form of IBD in which all layers of the bowel are involved
Crohn’s dz
Crohn’s dz may involve ___ of the GI tract
any portion
S/S specific to Crohn’s in addition to inflammation
malabsorption, malnutrition, weight loss
Form of IBD found only in the colon
ulcerative colitis
Main difference in ulcerative colitis vs Crohn’s
more severe risk of dehydration
Less risk for nutritional deficiency
An occlusion of either the small or large intestine that can be partial or complete
Intestinal obstruction
Pathogenesis of intestinal obstruction
obstruction > sequestration of gas & fluid > abdominal distention > pain, N/V, constipation or diarrhea
Loss of peristaltic motor activity in the intestine
paralytic ileus
Twisting of the intestine with occlusion of blood supply
Volvulus
Telescoping of one portion of the bowel into another
intussusception
Scar tissue from surgery or from chronic inflammation
Adhesions
Paralytic ileus is associated with ___
immobility, post-anesthesia, surgery, peritonitis, electrolyte imbalances, spinal trauma
herniations or saclike outpouchings of mucosa that protrude from the muscle layer of the intestine
diverticulum
Diverticulum most commonly occur in the ___
sigmoid colon
Asymptomatic diverticular dz
diverticulosis
