About GERD
Gastroesophageal reflux disease occurs when stomach acid refluxes back into the oesophagus, causing symptoms (heartburn, regurgitation, chest pain, cough) and/or mucosal damage. It is caused by dysfunction of the lower oesophageal sphincter (LOS) — the muscular valve between the oesophagus and stomach.
GERD is among the most common presentations in South African primary care. Omeprazole is the most frequently prescribed proton pump inhibitor (PPI) in SA — accounting for 47–51% of all PPI prescriptions on medical aid claims.
GERD is the lowest-complexity condition in the AURA Phase 1a set from a financial advisory perspective. It does not drive scheme selection, gap cover selection, or plan upgrading for the vast majority of patients.
Symptoms
Typical GERD symptoms: - Heartburn (burning sensation in the chest, usually after meals or when lying down) - Regurgitation (sour or bitter fluid rising into the throat or mouth) - Dyspepsia (upper abdominal discomfort or bloating)
Atypical GERD presentations: - Chronic cough (particularly nocturnal) - Hoarseness or voice changes (laryngopharyngeal reflux) - Asthma worsening - Dental erosion - Chest pain (non-cardiac)
Alarm features — require urgent investigation: - Difficulty swallowing (dysphagia) — food sticking in the oesophagus - Unintended weight loss - Black, tarry, or bloody stools (GI bleeding) - Persistent vomiting - Anaemia
These alarm features raise concern for Barrett's oesophagus, oesophageal stricture, or malignancy — requiring urgent gastroscopy (upper GI endoscopy).
Treatment Options
Step 1 — Lifestyle Modification
The most effective long-term intervention for GERD is lifestyle change: - Weight loss (even 5–10% reduction significantly reduces symptoms) - Elevate head of bed 15–20cm - Avoid lying down within 3 hours of eating - Reduce trigger foods: fatty/fried food, coffee, alcohol, chocolate, mint, citrus, spicy food - Stop smoking - Eat smaller meals; avoid eating late at night
Step 2 — Proton Pump Inhibitor (PPI) Therapy
PPIs are the most effective medication for GERD. They suppress gastric acid production by irreversibly blocking the proton pump in the stomach lining.
- Omeprazole 20–40mg daily (Altosec / generic) — most commonly prescribed PPI in SA (47–51% of PPI scripts). ~R90/month (generic). Take 30 minutes before the first meal.
- Esomeprazole 20–40mg daily (Nexium / generic) — S-isomer of omeprazole; slightly longer duration. ~R150/month
- Pantoprazole 40mg daily (Pantocid / generic) — alternative. ~R110/month
PPIs for GERD are funded from day-to-day (d2d) benefits. Generic omeprazole at ~R90/month is a minimal d2d cost covered by virtually all medical aid plans.
H2 blockers (famotidine, ranitidine) are less effective than PPIs but useful for breakthrough symptoms or when PPIs are not tolerated.
Step 3 — Specialist Referral and Investigation
If symptoms are atypical, refractory to PPI, or alarm features are present: - Gastroscopy (upper GI endoscopy): Visualises the oesophageal mucosa; detects Barrett's oesophagus, oesophagitis grade, strictures, hiatus hernia, or malignancy. Cost: ~R4,000–R5,000 at a private facility. - Oesophageal pH monitoring / impedance: Confirms acid exposure when diagnosis is uncertain. Specialist procedure. - Oesophageal manometry: Assesses LOS pressure and oesophageal motility.
Surgical Option
Laparoscopic Nissen fundoplication: Anti-reflux surgery. The fundus of the stomach is wrapped around the LOS to reinforce it. Very effective for PPI-refractory GERD or patients wishing to come off long-term PPI. Estimated cost: ~R85,000 (private). Laparoscopic surgeon + anaesthesiologist shortfall risk.
Annual Cost Estimates (Private Sector)
| Severity | Profile | Estimated Annual Cost |
|---|---|---|
| Mild | Lifestyle + intermittent/daily generic omeprazole | ~R1,080 |
| Moderate | Daily PPI + 2 GP reviews per year | ~R2,080 |
| Severe / Complicated | PPI + gastroscopy + gastroenterologist visit | ~R8,380–R13,380 |
The Coverage Reality
GERD is not CDL and not PMB. Everything is funded from d2d benefits: - Generic omeprazole (~R90/month): covered by virtually all scheme d2d benefits as chronic medication - GP consultations: standard GP consultation; scheme rate applies - Gastroscopy: requires pre-authorisation; gastroenterologist or surgeon performs it; specialist shortfall may apply - Anti-reflux surgery: PMB does not cover this electively; funded from scheme surgical benefit with specialist shortfall risk
Gap Cover Relevance
Very limited for most GERD patients. Only relevant if anti-reflux surgery or Barrett's-related investigation involves specialists billing above scheme rate.
The Talk to Eldon Angle
GERD is not a driver of scheme selection or plan upgrading for the vast majority of patients. Generic omeprazole costs R90/month and is covered by all schemes. The advisory insight for GERD is primarily clinical: know the alarm features, know when to escalate to gastroscopy, and know that anti-reflux surgery exists if medical therapy fails. These are clinical decisions, not financial ones.
