Ep 82: Reflux After Bariatric Surgery
This post is a companion to Episode 82 of the Bariatric Nutrition Coach Podcast. Listen to the full episode on Spotify or Apple Podcasts.
This episode was inspired by a listener question from Glenda, who is dealing with severe acid reflux after sleeve gastrectomy and has been recommended a revision to a duodenal switch. Reflux after bariatric surgery is more common than many people expect — and we really do not want it going unmanaged. Here is what you need to know.
Why Reflux Happens After Bariatric Surgery
Acid reflux — where stomach contents travel up into the oesophagus — can occur or worsen after sleeve gastrectomy in particular. The sleeve creates a tube-shaped stomach with higher internal pressure, which can push stomach acid upward. After bypass surgery, reflux is generally less common because the anatomy changes reduce the amount of acid reaching the oesophagus.
Reflux is not just uncomfortable — it can be damaging. Stomach contents are acidic, and repeated exposure to the oesophageal lining over time can cause real harm. Please do not ignore it or manage it alone. Please raise it with your bariatric surgeon or GP.
Dietary and Lifestyle Strategies to Help
Several dietary habits can significantly reduce reflux symptoms. Eating small, regular meals — rather than large ones — reduces the amount of pressure in the stomach at any one time. Not drinking during or immediately after meals helps too. Avoiding very fatty, spicy, or acidic foods can reduce triggers. Not lying down within two to three hours of eating, and elevating the head of your bed if night-time reflux is a problem, are both well-evidenced strategies.
Common trigger foods include coffee, chocolate, alcohol, carbonated drinks, citrus, and tomato-based products — though triggers are individual, so keeping a brief food and symptom diary can help you identify yours.
When to Seek Medical Help
If reflux is frequent, severe, or not responding to dietary changes, please contact your bariatric centre or GP. Medication (proton pump inhibitors) is often very effective. And in some cases — as Glenda is navigating — a surgical revision may be discussed. That is a big decision and one worth taking the time to explore thoroughly with your surgical team.
