GERD Presentation

Introduction to GERD

  • GERD: Gastroesophageal reflux disease

  • Case Study: John Smith, 45-year-old male office worker

    • Chief complaint: Frequent heartburn, worsens at night, burning sensation from stomach to chest, sour/bitter taste during eating

    • Symptoms duration: 6 months, recently worsened

    • Aggravating factors: Lying down, large meals

    • Alleviating factors: Temporary relief from over-the-counter antacids

    • Additional symptoms: Occasional regurgitation, mild bloating, no significant weight loss, no gastrointestinal bleeding

Diagnosis of GERD

  • Physical examination: Mild epigastric tenderness, normal chest exam, no acute distress

  • Important anatomical structures:

    • Stomach: Contains gastric juice ( hydrochloric acid, water, enzymes) for digestion

    • Esophagus: Located in mediastinum, contains lower esophageal sphincter (LES)

    • Lower Esophageal Sphincter (LES):

      • Involuntary ring-shaped muscle

      • Prevents gastric contents from re-entering esophagus

    • Crural portion of diaphragm: Surrounds LES and maintains pressure

    • Autonomic nervous system: Controls involuntary processes of LES

Pathophysiology of GERD

  • GERD is chronic acid reflux

    • Reflux of gastric juice into esophagus due to weak/extended relaxation of LES

    • Consequences: Irritation, inflammation of esophageal lining

  • Possible complications:

    • Esophagitis: Inflammation causing bleeding/open sores

    • Esophageal stricture: Narrowing from scar tissue

    • Barrett's esophagus: Changes in esophageal tissue; risk for esophageal cancer

Common Causes and Risk Factors

  • Hiatal hernia: Lifts LES above diaphragm, weakening it

  • Obesity: Increases abdominal pressure, weakening diaphragm and LES

  • Smoking: Relaxation of LES and weakening diaphragm

Signs and Symptoms of GERD

  • Common symptoms: Sour taste, dry cough, sore throat, difficulty swallowing, regurgitation, heartburn, non-burning chest pain

  • Diagnosis: Chronic acid reflux at least twice weekly

Diagnostic Procedures for GERD

  • Upper endoscopy: Visual examination of esophagus with camera

  • Ambulatory acid probe test: Measures regurgitation duration

  • X-ray: Shows narrowing of esophagus

  • Esophageal manometry: Measures muscle contractions during swallowing

  • Transnasal esophagoscopy: Visualizes esophagus through the nose

Treatment Options for GERD

  • Non-prescription medications:

    • Antacids: Quick relief but not long-term

    • Histamine blockers: Reduce acid production

    • Proton pump inhibitors: Block acid production, may need prescription strength

  • Procedures:

    • Fundoplication: Wraps stomach around LES for support

    • LINX device: Magnetic beads support LES

    • Transoral incisionless fundoplication: Quick recovery with no incision

Stages of GERD Progression

  1. Stage 1 (Mild): Occasional heartburn/regurgitation (less than once/week)

  2. Stage 2 (Moderate): More frequent heartburn/regurgitation (about three times/week)

  3. Stage 3 (Severe): Frequent heartburn/regurgitation; atypical symptoms emerge

  4. Stage 4 (Advanced): May include precancerous lesions or esophageal cancer; Barrett's esophagus increases cancer risk

Impact on Daily Life and Occupations

  • Changes in physical activity; high-impact may worsen GERD

  • Increased absenteeism, reduced productivity, psychological distress

  • Nighttime reflux can disturb sleep

Adaptive Techniques and Lifestyle Interventions

  • Elevate head of bed: Prevents nighttime reflux; recommended 6-8 inches

  • Smaller meals: Advising more frequent, smaller meals to reduce pressure

  • Trigger food identification: Maintain a food diary to avoid GERD triggers (spicy foods, caffeine)

  • Chewing gum: Stimulates saliva, neutralizes stomach acid

  • Breathing exercises: Strengthens diaphragm, reduces reflux

  • Weight management: Gradual weight loss to reduce intra-abdominal pressure

  • Proton pump inhibitors: (e.g., omeprazole) to relieve symptoms

  • Smoking and alcohol cessation: Reduce symptom severity by avoiding substances that relax LES

Summary and Conclusion

  • Importance of recognizing and managing GERD to improve quality of life and functioning

  • Various treatment and lifestyle modifications can significantly alleviate symptoms and prevent complications.
