GERD — gastroesophageal reflux disease — is a very common condition that affects between one in five and one in ten South African adults at some point. If you've been diagnosed, you're not alone, and the management is straightforward for most people.
The honest headline: GERD is manageable, inexpensive to treat, and for most people, has minimal impact on their financial planning or medical aid decisions. A tablet of generic omeprazole once daily solves the problem for millions of people. The more important question is whether you are managing it correctly and recognising when simple reflux has developed into something that warrants more attention.
What to Do Right Now: Five Steps
Step 1 — Start lifestyle changes first (or alongside medication)
The single most effective intervention for GERD is weight loss — even modest reductions of 5–10% of body weight significantly reduce symptom frequency and severity. This is more evidence-based than any medication for most patients.
Other practical changes that reduce reflux: - Don't lie down for at least 2–3 hours after eating - Elevate the head of your bed by 15–20cm (a wedge pillow works well) — especially if you have night symptoms - Reduce trigger foods: high-fat meals, coffee, alcohol, chocolate, mint, citrus, spicy food - Eat smaller meals; avoid large meals before bedtime - Stop smoking — it reduces LOS tone
For mild intermittent GERD, lifestyle modification alone may be sufficient. For frequent or severe symptoms, add a PPI.
Step 2 — Start a proton pump inhibitor (PPI)
PPIs are the most effective medication for GERD. Omeprazole 20mg once daily is the most commonly prescribed option in South Africa and is available as an inexpensive generic (~R90/month). Esomeprazole and pantoprazole are alternatives.
How to take it correctly: Take the PPI 30 minutes before your first meal of the day. PPIs work by reducing acid production after you eat — taking them on an empty stomach 30 minutes before eating ensures they're active when acid production is stimulated.
PPIs are funded through your scheme's day-to-day (d2d) benefit. GERD is NOT a CDL condition — there is no chronic medication benefit to register for. Your GP's prescription is all you need.
Step 3 — Know the difference between simple GERD and alarm features
This is the most clinically important thing to understand. Simple GERD (heartburn + regurgitation, responding to lifestyle + PPI) does not require investigation. But certain symptoms signal that something more serious may be going on and requires urgent gastroscopy (an upper GI endoscopy):
- Difficulty swallowing (food sticking, having to wash food down with water) — could be oesophageal stricture or cancer
- Unintended weight loss — cancer until proven otherwise
- Black or bloody stools — GI bleeding
- Anaemia with GERD symptoms — blood loss from oesophageal inflammation or cancer
- Persistent vomiting
If you have any of these, do not wait for a PPI to work. See your doctor and ask for a gastroscopy referral.
Step 4 — Understand what Barrett's oesophagus is
Long-standing acid reflux (typically > 5 years) can, in some people, cause the normal oesophageal lining to be replaced by a type of intestinal lining — this is called Barrett's oesophagus. Barrett's is a pre-cancerous change that increases the risk of oesophageal adenocarcinoma.
If you have had GERD symptoms for more than 5 years, your GP may recommend a screening gastroscopy to check for Barrett's. Once Barrett's is diagnosed, surveillance gastroscopy is required at regular intervals (typically 3–5 years for low-risk Barrett's; more frequently for dysplasia).
Barrett's changes the advisory landscape — surveillance gastroscopy adds to the annual cost, and if dysplasia or early cancer develops, PMB oncology cover applies.
Step 5 — Know that long-term PPI use has some considerations
PPIs are safe for most people when used long-term. Evidence does not support the more extreme concerns sometimes raised (dementia, kidney damage) at standard doses. However: - Long-term PPI use reduces stomach acid, which is needed to absorb vitamin B12, magnesium, and calcium — periodic checking of these is reasonable in long-term users - PPIs can increase the risk of C. difficile intestinal infection if taken during antibiotic courses - Some drug interactions exist — ask your pharmacist if you're on other medications
Your Most Important Questions, Answered
Do I need a gastroscopy? Not routinely, unless you have alarm features (dysphagia, weight loss, bleeding, anaemia) or have had GERD symptoms for many years without investigation. A gastroscopy may be recommended to grade oesophagitis or screen for Barrett's in certain patients. Discuss with your GP.
Can I come off the PPI? Yes. PPIs are not addictive. After a treatment course (4–8 weeks), many people successfully step down to intermittent use or to lifestyle management only. Some people with more severe reflux need long-term daily PPI. If you've been on a PPI for more than a year and haven't tried stepping down, ask your GP.
Is there surgery? Laparoscopic Nissen fundoplication is an anti-reflux surgery that is highly effective for PPI-refractory GERD or patients who prefer not to take medication long-term. It is available at private hospitals. Cost: ~R85,000. A laparoscopic surgeon and anaesthesiologist shortfall risk is the financial consideration.
What does this cost on my medical aid? Generic omeprazole ~R90/month. Annual cost of simple GERD management: R1,080–R2,080. Your scheme's d2d benefit covers this. There is no CDL registration required and no complex scheme decision to make.
Your Scheme Coverage for GERD
GERD management — PPI, GP consultations — is funded from your scheme's day-to-day (d2d) benefit. There is nothing to register for. No CDL, no exceptional needs, no specialist pre-authorisation for PPI prescriptions.
If you need gastroscopy (for alarm features or Barrett's screening), this requires a pre-authorisation from your scheme and is performed by a gastroenterologist or specialist surgeon. A shortfall above scheme rate may apply.
GERD does not affect your choice of medical aid plan or scheme. Choose your scheme based on other healthcare needs.
