Throat Symptoms from Acid Reflux: When to See an ENT Specialist

• Acid reflux does not always cause heartburn — many patients experience it purely as throat symptoms

• LPR (laryngopharyngeal reflux) can cause persistent throat clearing, hoarseness, a lump sensation, or chronic cough with no chest symptoms

• An ENT specialist rather than a gastroenterologist is often better placed to identify and manage this presentation

• This post explains the difference between classic reflux and the throat-only variant

Acid reflux is widely associated with heartburn — a burning sensation in the chest that most people recognise immediately. But a significant number of patients experience reflux in a completely different way: with symptoms in the throat, not the chest. No heartburn. No obvious gastric complaint. Just a persistent throat problem that doesn't seem to go away.

This pattern is known as laryngopharyngeal reflux, or LPR. It is one of the most commonly misdiagnosed conditions I see in ENT practice, and one of the most frequently overlooked. Many patients have seen multiple doctors — GPs, gastroenterologists, even allergists — before someone identifies reflux as the underlying cause of their throat symptoms.

This article explains what LPR is, how it presents, how I assess and treat it, and when throat symptoms from reflux require urgent attention.

What Is Laryngopharyngeal Reflux (LPR)?

In typical gastro-oesophageal reflux (GORD), stomach acid travels up into the oesophagus, causing heartburn and indigestion. In LPR, the reflux travels higher — past the upper oesophageal sphincter and into the throat and voice box (larynx). At this level, even small amounts of acid or non-acid reflux can irritate the delicate lining of the larynx and pharynx.

The larynx is far more sensitive to reflux than the oesophagus. The oesophagus has some protective mechanisms against acid exposure; the larynx does not. This is why LPR can cause significant symptoms even when reflux episodes are relatively infrequent — and why heartburn is often absent entirely.

How Does LPR Present?

The symptoms of LPR are often vague and easy to attribute to other causes. This is precisely why it goes unrecognised for so long.

The most common symptoms I see in clinic are:

Throat clearing — a persistent urge to clear the throat, often described as a constant tickle or mucus sensation. Patients frequently assume this is post-nasal drip or an allergy, and are often treated for those conditions first without improvement.

Globus — a sensation of a lump or something stuck in the throat, even when swallowing is not actually impaired. This can be very distressing and is often mistaken for anxiety or a serious structural problem.

Hoarseness — a change in voice quality, particularly noticeable in the morning, caused by reflux irritating the vocal cords overnight. Singers and professional voice users are often particularly affected.

Chronic cough — a dry, irritating cough that persists despite treatment for asthma or post-nasal drip. When cough does not respond to standard respiratory treatments, LPR should always be considered.

Throat discomfort or burning — a sensation of irritation or rawness at the back of the throat, distinct from the chest burning of typical reflux.

Many patients present having already tried antihistamines, nasal sprays, or cough suppressants without benefit. In a significant number of cases, the correct diagnosis — and with it, effective treatment — has been delayed by months or years.

How I Assess LPR

When a patient presents with any of the above symptoms, my first step is a thorough history. I want to understand when symptoms occur — particularly whether they are worse in the morning, after meals, or when lying down — and whether there is any heartburn or indigestion, even occasionally.

I then perform a laryngoscopy in clinic. This is a brief, non-invasive examination using a thin flexible camera passed gently through the nose to visualise the voice box and surrounding structures. It takes only a few minutes and requires no sedation.

Laryngoscopy allows me to look directly at the larynx for the characteristic signs of LPR — redness, swelling, or irritation of the vocal cords and the structures around them. These findings, combined with the symptom pattern, are usually sufficient to make a clinical diagnosis and begin treatment.

In some cases — particularly where symptoms are atypical, severe, or not responding to initial treatment — further investigation such as pH impedance testing may be arranged. But for most patients, laryngoscopy and clinical assessment provide a clear enough picture to proceed.

How I Treat LPR

LPR is managed medically in the first instance. My standard approach combines two treatments:

Proton pump inhibitors (PPIs) reduce the production of stomach acid, decreasing the acidity of any reflux that reaches the throat. They are taken regularly, usually for a period of weeks to months, and work best when taken consistently as prescribed.

Gaviscon Advance creates a physical barrier — a raft — on top of the stomach contents, reducing the likelihood of reflux reaching the throat. Unlike standard antacids, Gaviscon Advance is specifically designed to address the reflux mechanism rather than simply neutralising acid after the fact. I find this combination of acid suppression and physical barrier to be effective for the majority of patients.

Alongside medication, dietary and lifestyle modifications play an important supporting role:

• Avoiding trigger foods — particularly fatty meals, coffee, alcohol, citrus, and chocolate

• Not eating within two to three hours of lying down

• Elevating the head of the bed slightly

• Avoiding tight clothing around the abdomen

• Weight management where relevant

  
  

Most patients notice meaningful improvement within four to eight weeks of starting treatment, though full resolution of symptoms can take longer. Follow-up is important to assess response and adjust treatment if needed.

Red Flag Symptoms: When to Seek Urgent Assessment

While LPR is a benign condition, some throat symptoms require prompt evaluation to rule out more serious causes. I would always want to see a patient urgently if they experience:

Persistent hoarseness lasting more than three weeks — hoarseness that does not resolve warrants laryngoscopy to examine the vocal cords and exclude other causes, including malignancy.

A lump in the neck — a new or growing neck lump should always be assessed by an ENT specialist without delay.

Difficulty swallowing — particularly if swallowing is painful, or if there is a sensation of food sticking, this requires investigation to rule out structural causes in the oesophagus or throat.

Unexplained weight loss alongside throat symptoms — this combination always warrants further assessment.

These symptoms may well have a benign explanation, but they should not be left unassessed or attributed to reflux without examination.

Why See an ENT Specialist for Reflux?

LPR sits at the intersection of gastroenterology and ENT. While gastroenterologists manage the oesophageal and gastric aspects of reflux, the throat and voice box are the domain of the ENT surgeon. Laryngoscopy — the key diagnostic tool for LPR — is performed in ENT clinic, not in a gastroenterology setting.

For patients whose primary symptoms are in the throat rather than the stomach, an ENT assessment is often the most direct route to diagnosis and treatment. I manage LPR in my own practice, including the laryngoscopy, clinical diagnosis, and medical treatment, without the need for onward referral in most cases.

If you have been experiencing persistent throat symptoms — particularly throat clearing, globus, hoarseness, or chronic cough — and have not found a satisfactory explanation or effective treatment, it is worth having your larynx examined.

Frequently Asked Questions

Can I have LPR without heartburn? Yes — this is common. Many patients with LPR have no heartburn at all. The absence of heartburn does not exclude reflux as a cause of throat symptoms.

How is LPR different from GORD? GORD primarily affects the oesophagus and causes heartburn and indigestion. LPR involves reflux reaching the throat and voice box, causing ENT symptoms. The two conditions can coexist but often present very differently.

How long does treatment take? Most patients notice improvement within four to eight weeks, but a full treatment course typically lasts several months. Some patients require longer-term management depending on their response.

Will I need an endoscopy? Not necessarily. For most LPR patients, laryngoscopy in clinic — which examines the throat and voice box — is sufficient. An upper GI endoscopy may be arranged in selected cases, particularly if oesophageal symptoms are also present.

Is LPR curable? LPR can be very effectively managed with the right treatment. Many patients achieve full resolution of symptoms. Lifestyle modifications alongside medication give the best long-term results.

When should I see a doctor urgently? If you have persistent hoarseness lasting more than three weeks, a new neck lump, difficulty swallowing, or unexplained weight loss alongside throat symptoms, seek an ENT assessment promptly.

Seeking Assessment

If you are experiencing persistent throat clearing, a globus sensation, hoarseness, or chronic cough — and particularly if these symptoms have not responded to treatment elsewhere — an ENT assessment with laryngoscopy is the appropriate next step.
