GERD
- Gastroesophageal reflux disease (GERD)
occurs when stomach acid frequently flows
back into the esophagus. This acid reflux
can irritate the lining of the esophagus
- Pathophysiology
- Abnormal lower esophageal sphincter
- Causes
- Hypotensive LES
- Inadequate response to increased
intraabdominal pressure
- TLESR (transient lower
esophageal sphincter relaxation)
- Hypotensive LES
- Sliding hiatal hernia
- Abnormal lower esophageal sphincter
- Complications
- Ulcers
- Strictures
- Respiratory problems
- Barrett's esophagus
- At least 1 cm of metaplastic columnar epithelium that replaces the
stratified squamous epithelium normally lining the distal esophagus
- At least 1 cm of metaplastic columnar epithelium that replaces the
stratified squamous epithelium normally lining the distal esophagus
- Ulcers
- Signs & Symptoms
- Heartburn , Dysphagia , Belching ,
Bad Breath , Erosion of the enamel
of the teeth , Regurgitation ,
Cough and Asthma
- Heartburn , Dysphagia , Belching ,
Bad Breath , Erosion of the enamel

- Investigations
- upper GI series
- upper endoscopy
- 24-hour esophageal pH study
- esophageal
impedance
testing
- upper GI series
- Predisposing factors
- Alcohol, Chocolate,
Obesity, Pregnancy,
Hiatal hernia
- Alcohol, Chocolate,

- Pharmacological management
- Antacids
- Antisecretory
drugs
- H2-receptor
antagonists
(cimetidine)
- Acid/Proton-pump
inhibitors (omeprazole)
- Muscarinic M1 receptor antagonists
- Prostaglandin analogues
- H2-receptor
antagonists
(cimetidine)
- Cytoprotective
drugs (colloidal
bismuth, sucralfate)
- both a cyto-protective and
anti-secretory action (misoprostol)
- Antacids
- Surgical
Treatment
