The Reflux Trap: When Heartburn Meds Aren’t the Answer
A persistent “lump” in the throat, that tell-tale burning in the chest, and a sour taste that won’t go away—for the estimated seven million people in the UK suffering from these symptoms, the diagnosis seems obvious: acid reflux.
However, a startling new analysis from The Functional Gut Clinic in London suggests that we might be getting it wrong. Researchers found that up to two-thirds of patients suspected of having reflux do not actually meet the medical criteria for the condition when properly tested. Instead, their agonizing symptoms are driven by a range of overlooked issues that feel almost identical to traditional heartburn.
What is GORD? (The Baseline)
Gastro-oesophageal reflux disease (GORD) occurs when the lower oesophageal sphincter—the valve between your throat and stomach—weakens. This allows stomach acid to leak upward, causing inflammation and pain. While lifestyle factors like weight, smoking, and diet play a role, many patients are immediately funneled toward Proton Pump Inhibitors (PPIs).
While PPIs are effective at shutting off acid production, they can become a double-edged sword if the root cause of the pain isn’t actually acid.

At least one in ten adults suffers persistent heartburn or reflux symptoms – around seven million

The Mimics: 5 Conditions That Feel Like Reflux
If your symptoms persist despite taking medication, you might be dealing with one of these “reflux mimics”:
1. SIBO (Small Intestinal Bacterial Overgrowth)
This is perhaps the most common misdiagnosis. SIBO occurs when bacteria migrate to the small intestine, where they don’t belong.
-
The Vicious Cycle: PPIs lower stomach acid, which normally acts as a barrier against bacteria. Without that acid, bacteria multiply, causing bloating and gas that pushes upward, creating a sensation that feels exactly like reflux.
-
High-Profile Cases: Celebrities like Selena Gomez and Melissa Suffield have recently shared their battles with SIBO, highlighting how it can cause extreme bloating and nausea often mistaken for other digestive issues.

2. Functional Dyspepsia & Hypersensitivity
Sometimes, the problem isn’t the acid—it’s the nerves.
-
The Gut-Brain Connection: In cases of functional dyspepsia or oesophageal hypersensitivity, the digestive tract becomes “hypersensitive.” Even normal levels of acid or the simple act of digestion can trigger intense pain signals to the brain.
-
The Clue: If a 24-hour acid test shows normal levels but you still feel the “burn,” your nerves may be the culprit.
3. Helicobacter pylori (H. pylori)
This stomach bacterium can irritate the stomach lining, causing ulcers and gastritis.
-
The Patient Story: Nurse Lauren Jackson, 35, spent years being told her “choking sensation” was reflux. It wasn’t until she insisted on a stool test that doctors found an H. pylori infection. After a course of antibiotics, her “reflux” finally began to clear.
4. EoE (Eosinophilic Oesophagitis)
This is an inflammatory condition often linked to allergies. It causes the oesophagus to swell, making it feel like food is “sticking” in your throat. Because it causes discomfort in the chest, it is frequently misidentified as GORD.

5. Achalasia
Affecting about 1 in 100,000 people, this rare condition occurs when the oesophageal valve fails to relax at all. This leads to progressive difficulty swallowing and regurgitation, often mistaken for severe, chronic reflux.
When Should You Be Concerned?
While most “heartburn” is manageable, experts warn against ignoring “red flag” symptoms that require urgent investigation:
-
Progressive difficulty swallowing (the feeling that food is stuck).
-
Unexplained weight loss.
-
Persistent vomiting.
-
Black or tarry stools.
The Bottom Line
“In most people, it really is reflux,” says consultant surgeon Paul Goldsmith. “But if things aren’t improving, or if medication is actually making your bloating worse, it’s time to stop the repeat prescriptions and start proper testing.”
If your current treatment has failed to provide relief within six to eight weeks, it may be time to ask your doctor about SIBO breath tests or H. pylori screening.
