Gastro-Oesophageal Reflux Disease (GORD)
With GORD, there's a reflux of gastric contents back up through a defective lower oesophageal sphincter (LOS), causing inflammation (= Reflux Oesophagitis). Risk factors for it include:
Hiatus hernia - weakens LOS
Smoking, Alcohol, Coffee - decreases LOS tone
Obesity, Pregnancy - increases intra-abdominal pressure
Intake of specific foods e.g. citrus foods, spicy foods, fat
Differentials - Peptic Ulcer Disease, Oesophageal cancer, Oesophageal spasm, Angina
Presentation:
Typical presenting symptom is heartburn, which is worse on eating, lying down or bending over. Other atypical symptoms that patients may present with is:
Chronic cough
Belching
Bloating
Acid brash - acid in throat causes increased salivation
Odynophagia - painful swallow due to oesophagitis/ulcerations
Hoarse voice
Tooth erosion
Investigations:
Mainly a clinical diagnosis, but investigations that help include:
Trial standard-dose PPI
OGD if alarming features or atypical, persistent or relapsing symptoms
Oesophageal manometry to assess LOS competence
Management:
Conservative:
Weight loss
Small, lighter meals
Avoid eating late at night (3+ hrs)
Sleep on left side
Less alcohol and coffee
Medical - PPI (1st line), Antacids, H2 receptor antagonist (Antihistamine) e.g. ranitidine - helps reduce stomach acid
Surgical - Laparoscopic fundoplication
Complications:
Barrett’s Oesophagus
Stricture - Presents as progressive dysphagia
Oesophageal ulcer
Bleeding - Presents as haematemesis/melaena
Oesophageal cancer
