Why Your Reflux Keeps Coming Back (Even on Medication)

If you’re taking medication for reflux but still struggling with symptoms, you’re not alone. While acid-reducing medicines can help relieve discomfort, they don’t always fix the underlying cause. Understanding why reflux persists is the first step toward finding lasting relief.

What causes persistent reflux?

Reflux happens when stomach contents flow back into the oesophagus. When this continues despite medication, there’s usually a mechanical or structural issue involved, not just too much acid.

Weak lower oesophageal sphincter (LES): This valve between your oesophagus and stomach can lose strength over time, allowing acid to escape upward. Medication can’t restore its function.

Hiatal hernia: When part of the stomach pushes through the diaphragm, it disrupts the natural barrier that prevents reflux. Surgery may be required to correct this.

Delayed stomach emptying or high pressure: Food staying too long in the stomach, tight clothing, or excess abdominal pressure (e.g. due to weight gain) can all increase reflux risk.

Lifestyle factors: Alcohol, caffeine, smoking, large or late meals, and certain foods like chocolate or fatty meals can all make symptoms worse, even on medication.

When to see a specialist

If reflux continues despite lifestyle changes and medication, it’s time to talk to a specialist. Warning signs that suggest that reflux may be leading to complications include:

• Difficulty swallowing or food feeling stuck
• Ongoing cough, hoarseness or throat clearing
• Chest pain not related to the heart
• Unexplained weight loss or vomiting

These symptoms suggest reflux may be more severe or linked to a structural problem that needs further assessment.

Reflux testing and treatment options

At Upper GI Surgery, we can perform advanced tests to identify what’s really causing your symptoms. These include endoscopy to check for inflammation and hiatus hernia, pH monitoring to measure acid levels, and manometry to test valve function. 

If testing shows a mechanical issue, such as a weak valve or hiatal hernia, surgery may be the most effective solution. Procedures like laparoscopic fundoplication can restore the natural barrier between your stomach and oesophagus, treating the root cause rather than just the acid.

Persistent reflux doesn’t mean you have to live on medication forever. Identifying the underlying cause through specialist testing can lead to more effective treatment and lasting relief.
