— Millions of people with a persistent cough, wheezing or breathing difficulties have been told it’s asthma. But new survey data suggests that for a significant number of them, the real cause could actually be acid reflux — a digestive problem most people would never think to connect to their breathing.
New research from wipeoutreflux.com has found that 42% of people who were first told they had asthma later discovered that acid reflux was actually the real or major cause of their symptoms. And 58% of adults with breathing-related symptoms — coughing, wheezing, shortness of breath — were initially diagnosed with asthma in the first place.
Nearly half of all asthma diagnoses in people with these kinds of symptoms may be missing the real picture.
THE TYPE OF ACID REFLUX MOST PEOPLE HAVE NEVER HEARD OF
Most people are familiar with classic acid reflux — the burning sensation that rises from the stomach after a heavy meal. But there is a lesser-known form that behaves very differently.
Doctors call it laryngopharyngeal reflux — or LPR. Most people call it silent reflux. The reason it’s called silent is simple: it usually causes no heartburn at all.
With silent reflux, stomach acid travels further than usual — all the way up past the chest, through the throat, and into the voice box and airway. Because it doesn’t pool in the oesophagus, there’s no burning sensation. Instead, patients experience:
A persistent dry cough — often worse in the morning or when lying down
Wheezing or a feeling of tightness in the chest
Shortness of breath, especially when breathing in
A hoarse or croaky voice, particularly first thing in the morning
The constant feeling of something stuck in the throat
These are also the symptoms of asthma. It is not difficult to understand how the wrong diagnosis gets made.
THE SCIENCE BEHIND IT
The connection between acid reflux and breathing symptoms is well established in medical research. Studies have found that up to 75% of people with asthma also show signs of acid reflux when properly tested. A 2021 study published in Scientific Reports found that asthma patients are approximately three times more likely to have silent reflux than people without asthma. And when reflux is properly treated in people who have both conditions, around 70% see genuine improvement in their breathing symptoms.
Three mechanisms explain the link: acid irritating the oesophagus triggers a nerve reflex that tightens the airways; microscopic amounts of stomach contents breathed into the airway cause direct inflammation; and chronic throat inflammation from reflux worsens inflammation further down in the lungs.
WHY IT KEEPS GETTING MISSED
Because silent reflux doesn’t cause heartburn, neither patients nor doctors think to look at the digestive system when breathing symptoms appear. A survey of over 500 ear, nose and throat specialists found that only one in three felt confident in their knowledge of silent reflux.
There is also a troubling complication: some common asthma medications — including reliever inhalers — relax the muscle valve at the top of the stomach that keeps acid in place. For someone whose symptoms are actually driven by undiagnosed reflux, their asthma medication can make the underlying problem worse, creating a cycle that continues for years undetected.
“The pattern I see again and again is someone who has been on asthma medication for years and it’s never really worked properly,” said David Gray, founder of wipeoutreflux.com. “People are not suffering from something untreatable. They’re suffering from something undiagnosed. Those are very different problems — and the second one has a solution.”
THE BIGGER PICTURE
Around 25 million people in the United States are currently receiving treatment for asthma. In the UK, the figure is around 5.4 million. If the survey findings are broadly representative, the number of people missing a silent reflux diagnosis within those populations is potentially very large.
For anyone whose breathing symptoms have never been fully explained — or whose asthma treatment has never quite worked the way it should — it may be time to ask a different question. Not “how do I manage my asthma better?” But “is asthma actually what this is?”
