Condition

GERD / Acid Reflux: Managing Heartburn and Oesophageal Damage

GERD affects 20–30% of Western adults. It's highly treatable with lifestyle changes and PPIs — but persistent symptoms need investigation to rule out Barrett's oesophagus and oesophageal cancer.

Prevalence
20–30% of Western adults
Barrett's oesophagus
Affects ~10% with long-term GERD
PPI efficacy
80–90% symptom control
Alarm symptoms
Dysphagia, weight loss → urgent endoscopy
Alarm Symptoms Need Urgent EndoscopyDifficulty swallowing (dysphagia), persistent vomiting, unintentional weight loss, vomiting blood, or new heartburn over age 55 — these require urgent upper GI endoscopy to exclude cancer.

Dietary Triggers

TriggerMechanism
High-fat foodsRelax lower oesophageal sphincter (LOS)
Chocolate, peppermintRelax LOS
Coffee and alcoholStimulate acid secretion + relax LOS
Carbonated drinksIncrease gastric pressure → reflux
Tomatoes and citrusAcidic — directly irritate inflamed oesophagus
Late meals (within 3 hours of bed)Gastric distension when lying → reflux

Management Ladder

  1. Lifestyle: elevate bed head 15–20 cm; avoid triggers; lose weight (strongly linked); eat smaller meals; don't lie down for 3 hours after eating
  2. Antacids (Gaviscon, Rennies) — neutralise acid; symptom relief only
  3. H2 blockers (famotidine, ranitidine) — reduce acid for mild GERD
  4. PPIs (omeprazole, lansoprazole, esomeprazole) — most effective acid suppression; use lowest effective dose; consider step-down after 8 weeks
  5. Laparoscopic fundoplication — surgical option for refractory GERD or those refusing lifelong PPIs
Take PPIs CorrectlyPPIs work best taken 30–60 minutes before the first meal of the day. Taking them with food significantly reduces their effectiveness. Many people take them incorrectly and assume they're not working.
Are PPIs safe long term?
PPIs are generally safe for long-term use, but long-term use (>1 year) is associated with reduced vitamin B12 and magnesium absorption, increased fracture risk, and C. difficile diarrhoea. Use the lowest effective dose and review annually.
What is Barrett's oesophagus?
A pre-cancerous condition where the normal oesophageal lining is replaced by intestinal-type cells — caused by chronic acid reflux. It requires endoscopic surveillance every 2–5 years depending on grade of dysplasia.
How is GERD diagnosed?
Usually a clinical diagnosis based on typical symptoms responding to PPIs. 24-hour ambulatory pH monitoring is the gold standard. Upper GI endoscopy is used if alarm features are present or treatment fails.
Can GERD cause a cough?
Yes — extra-oesophageal GERD causes hoarseness, chronic cough, laryngitis, and asthma-like symptoms. A trial of high-dose PPI for 8 weeks is both diagnostic and therapeutic.
