Gastric Esophageal Reflux Flashcards
(42 cards)
What is GERD?
Common problem
Chronic manifestation of mucosal damage
What causes GERD
Caused by reflux of gastric contents into lower esophagus
Is GERD a disease?
No it is a syndrome
GERD results when?
Defenses of lower esophagus are overwhelmed by reflux of gastric contents into esophagus
Reflux of HCl acid and pepsin secretions cause irritation and inflammation
Intestinal proteolytic enzymes and bile salts add to irritation
What are Predisposing factors of GERD
Hiatal Hernia
Decreased esophageal clearance
Decraesed Gastric Emptying
Hiatal hernia?
Incompetent lower esophageal sphincter (LES): Biggest culprate
Causing:
Antireflux barrier
What is decreasesed esophageal clearance?
incompetent LES (lower esophageal sphincter) takes longer for food to leave esophagus
What does incompetent LES cause?
Primary factor in GERD
Results in ↓ pressure in distal portion of esophagus
Gastric contents move from stomach to esophagus
Can be due to certain foods (caffeine, chocolate, peppermint) and drugs (anticholinergics): decrease pressure in LES increasing GERD
Other risk factors?
Obesity is a risk factor
Pregnant women are at increased risk
Cigarette and cigar smoking can contribute to GERD
Hiatal hernia is a common cause of GERD
Symptoms of GERD?
Heartburn (pyrosis)
Dyspesia
Regurgitation
Symptoms of Heartburn?
Most common clinical manifestation
Burning, tight sensation felt beneath the lower sternum and spreading upward to throat or jaw
Felt intermittently
Symptoms of Dyspepsia
Pain or discomfort centered in upper abdomen
Symptoms of regurgitation?
Described as hot, bitter, or sour liquid coming into throat or mouth
Hypersalivation may also be reported
Most individuals have mild symptoms such as?
Heartburn after a meal:
to consider as GERD it will happen at least twice a week
No evidence of mucosal damage
When does Heartburn occur?
Following ingestion of food or drugs that ↓ LES pressure
Directly irritates esophageal mucosa
Individual may also report respiratory symptoms such as?
Wheezing
Coughing
Dyspnea
Nocturnal coughing with loss of sleep
Can mimic asthma due to inflammation of the trachea causing voice hoarseness and sore throat
Otolaryngologic symptoms include
Hoarseness
Sore throat
Lump in throat
Choking
Symptoms of GERD-related chest pain
Described as burning, squeezing, or radiating to back, neck, jaw, or arms
Can mimic angina
More common in older adults with GERD
Relieved with antacids
Complications of GERD
òEsophagitis
Barrett’s esophagus (esophageal metaplasia): When healing process occurs: follow up with biopsy can be cancerous
Respiratory
Potential for asthma, bronchitis, and pneumonia
Dental erosion
From acid reflux into mouth
Especially posterior teeth
Diagnostic Studies
History and physical examination
Barium swallow
Upper GI endoscopy
Biopsy and cytologic specimens
Esophageal manometric (motility) studies: measures pressure of LES
Radionuclide tests
Detect reflux of gastric contents
Demonstrate rate of esophageal clearance
Monitoring pH
Laboratory or 24-hour ambulatory
Determine esophageal pH by using specially designed probes
Nutritional Therapy
Decrease high-fat foods
Take fluids between rather than with meals
Avoid milk products at night: Temporarily helps but has a rebound effect due to calcium increasing acid content
Avoid late-night snacking or meals
Avoid chocolate, peppermint, caffeine, tomato products, orange juice
Weight reduction therapy
Chewing gum and oral lozenges can increase saliva production and help patients with mild symptoms
What kind of drug therapy is given?
Proton pump inhibitors (PPIs)
What are common PPI’s?
omeprazole (Prilosec)
esomeprazole (Nexium)
How do PPI’s help?
Promote esophageal healing in 80% to 90% of patients
Decrease incidence of esophageal strictures
Decrease the rate of gastric acid secretion
