Gastroesophageal Reflux Disease

Gastroesophageal Reflux Disease (GERD) is a chronic gastrointestinal disorder characterized by the retrograde flow of gastroduodenal contents into the esophagus, oral cavity, or lungs. This retrograde movement leads to troublesome symptoms and/or mucosal injury. It is one of the most common digestive disorders managed in primary care globally.

The primary cause of GERD is a dysfunctional antireflux barrier at the gastroesophageal junction. Key factors include:

• Transient Lower Esophageal Sphincter Relaxations (TLESRs): Spontaneous LES relaxations unassociated with swallowing.


• Hypotensive LES: Low basal resting tone of the lower esophageal sphincter.


• Anatomical Defects: Hiatal hernia disrupting the diaphragmatic pinch.


• Impaired Gastric Emptying: Delayed emptying increases intragastric pressure.


• Lifestyle & Diet: Obesity, pregnancy, smoking, high-fat diets, caffeine, and alcohol.

GERD occurs when refluxed acidic gastric juice, pepsin, and occasionally bile acids overcome the esophageal defense mechanisms (luminal clearance, epithelial barrier resistance). Acid and pepsin induce chemical injury to the squamous epithelium, leading to intercellular space dilation, inflammation, and eventual mucosal erosions. Chronic exposure can cause replacement of the normal squamous epithelium with columnar-metaplastic epithelium (Barrett's esophagus).

• Prevalence: Approximately 18–28% in North America, 9–26% in Europe, and 5–10% in East Asia.
• Age: Can occur at any age, but prevalence increases significantly after

• Gender: Equal overall prevalence between sexes, but males have a higher risk of developing erosive esophagitis, Barrett's esophagus, and esophageal adenocarcinoma.

• Obesity (elevates intra-abdominal pressure)
• Hiatal hernia
• Pregnancy
• Connective tissue disorders (e.g., scleroderma)
• Smoking and alcohol consumption
• Medications (e.g., NSAIDs, calcium channel blockers, anticholinergics)

Physical examination is usually unremarkable in uncomplicated cases. Key findings in atypical or complicated cases include:

• HEENT: Dental enamel erosion, pharyngeal erythema, vocal cord edema.


• Pulmonary: Wheezing or crackles indicating microaspiration.


• Abdomen: Mild epigastric tenderness to deep palpation.

• Upper Endoscopy (EGD): Primary tool to evaluate mucosa. Essential if alarm features (dysphagia, weight loss) are present. Findings include erosions, ulcerations, or Barrett's mucosal changes.
• Barium Swallow: Evaluates esophageal anatomy and motility. Shows barium reflux, hiatal hernia, or luminal narrowing indicating a stricture.

• Coronary Artery Disease (CAD): Can present with mimic chest pain. Differentiated by ECG, cardiac enzymes, and exercise tolerance tests.
• Eosinophilic Esophagitis (EoE): Characterized by dysphagia and trachealization of the esophagus on endoscopy. Confirmed by $>15$ eosinophils per high-power field on biopsy.
• Esophageal Motility Disorders (e.g., Achalasia): Shows birds-beak appearance on barium swallow and incomplete LES relaxation on manometry.

• Erosive Esophagitis: Mucosal ulceration and bleeding.
• Esophageal Strictures: Fibrotic narrowing from chronic inflammation.
• Barrett’s Esophagus: Intestinal metaplasia, a precursor to adenocarcinoma.
• Esophageal Adenocarcinoma: Highly lethal malignancy.
• Aspiration Pneumonia: Secondary to nocturnal microaspiration.

The prognosis is excellent with lifestyle adjustments and appropriate pharmacotherapy. Most patients achieve symptom control. However, GERD is highly recurrent if therapy is discontinued, often requiring long-term maintenance treatment.

• Primary prevention involves maintaining a healthy body mass index (BMI) and avoiding tobacco.
• Secondary prevention includes routine endoscopic surveillance for patients diagnosed with Barrett's esophagus.
