Globus is the sensation of a lump or tightness in the throat with no actual obstruction
Laryngopharyngeal reflux (LPR) is a common cause — and many patients have no heartburn at all
This post explains why throat symptoms can occur without classic reflux signs
Diagnosis and management options are outlined
The sensation of something stuck in the throat — a lump, a tightness, a persistent feeling that something is there even when swallowing is not painful and nothing is actually obstructing — is one of the most common and most anxiety-provoking symptoms I see in ENT clinic. Patients often arrive convinced they have a serious underlying condition. In the majority of cases, the cause is either globus pharyngeus or laryngopharyngeal reflux (LPR) — both highly treatable once correctly identified.
This article explains what these conditions are, how they differ, how they are assessed, and what can be done about them.
What Is Globus Pharyngeus?
Globus pharyngeus — often simply called globus — is the medical term for the persistent sensation of a lump, tightness, or foreign body in the throat in the absence of any structural abnormality. It is one of the most common ENT presentations and accounts for a significant proportion of new ENT referrals.
The term comes from the Latin globus, meaning ball or sphere — reflecting the characteristic description patients give of feeling as though something round is lodged in the throat, typically at the level of the Adam's apple or just below it.
Crucially, globus is defined by the absence of true dysphagia — patients with globus can swallow normally, and the sensation often paradoxically improves during eating and drinking, only to return afterwards. This distinguishing feature is important: true swallowing difficulty (dysphagia) requires investigation for structural causes, whereas the globus sensation in the absence of dysphagia has a different and more benign differential diagnosis.
What Causes Globus?
The exact mechanism of globus is not fully understood, but several factors are recognised as contributors:
Laryngopharyngeal Reflux (LPR)
LPR is the most common identifiable cause of globus and deserves detailed discussion in its own right (see below). Stomach contents — acid and non-acid — reflux up beyond the oesophagus into the throat and voice box, causing inflammation and irritation of the laryngeal and pharyngeal mucosa. This inflammation produces the characteristic lump sensation, alongside throat clearing, chronic cough, and voice changes.
Muscle Tension
The throat contains a complex arrangement of muscles involved in swallowing, speaking, and breathing. When these muscles are held in a state of chronic tension — often related to stress, anxiety, or postural habits — they can produce a persistent sensation of tightness or a lump. This is sometimes called muscle tension dysphonia when it affects the voice, but the same mechanism can produce globus without voice changes.
Anxiety and Stress
There is a well-established relationship between psychological stress and globus. The throat is particularly sensitive to the physical manifestations of anxiety — many people are familiar with the sensation of a "lump in the throat" during emotional moments. In some patients, chronic anxiety perpetuates this sensation.
Upper Oesophageal Dysfunction
Abnormal function of the upper oesophageal sphincter — the muscular valve between the throat and the oesophagus — can contribute to globus in some patients.
Post-Nasal Drip
Mucus dripping from the back of the nose onto the throat can produce a persistent sensation of something being present, particularly in patients with allergic rhinitis or chronic sinusitis.
An enlarged thyroid gland (goitre) or thyroid nodule can occasionally cause a throat sensation by direct compression. This is why thyroid examination is part of a thorough globus assessment.
What Is Laryngopharyngeal Reflux (LPR)?
Laryngopharyngeal reflux is a condition in which stomach contents travel upward beyond the oesophagus and reach the throat and voice box. It is distinct from gastro-oesophageal reflux disease (GORD/GERD), which typically causes heartburn — and this distinction is one of the reasons LPR is so frequently missed or misdiagnosed.
Why LPR Is Different From Heartburn
The oesophagus is relatively tolerant of acid — it has protective mechanisms that allow it to handle a degree of reflux without significant damage. The throat and voice box, however, are exquisitely sensitive. Even small amounts of reflux reaching the laryngopharynx can cause significant mucosal irritation and inflammation.
This is why the majority of patients with LPR do not experience heartburn. They present instead with throat symptoms — and are often told by their GP that they cannot have reflux because they have no heartburn. This is incorrect. LPR and GORD are distinct conditions with overlapping but different symptom profiles.
Symptoms of LPR
The classic symptom cluster of LPR includes:
Globus — the persistent lump or tightness in the throat
Chronic throat clearing — often the most troublesome symptom, driven by the sensation of mucus or irritation in the throat
Chronic cough — a dry, irritating cough that worsens at night or after eating
Hoarse or rough voice — particularly in the morning
Excess mucus or post-nasal drip sensation
Difficulty swallowing — mild, and often described as food sitting in the throat rather than true obstruction
Burning sensation in the throat — less common than in GORD but present in some patients
What Triggers LPR?
Common dietary and lifestyle triggers include:
Coffee and caffeinated drinks
Alcohol
Spicy, fatty, or acidic foods
Chocolate and peppermint
Eating large meals or eating within three hours of lying down
Carbonated drinks
Smoking
Excess weight — which increases intra-abdominal pressure and promotes reflux
How Are Globus and LPR Assessed?
Clinical History
A detailed history is the most important part of the assessment. I ask about the character and location of the throat sensation, its relationship to eating and swallowing, any associated symptoms, dietary habits, stress levels, and any history of voice change, cough, or ear symptoms. The Reflux Symptom Index (RSI) — a validated questionnaire — helps quantify the symptom burden and response to treatment.
Flexible Nasolaryngoscopy
This is the key examination — a thin flexible camera passed through the nose allows direct visualisation of the entire throat and voice box in clinic. In LPR, characteristic findings include redness and swelling of the arytenoids (the cartilages at the back of the voice box), thickening of the posterior laryngeal mucosa, and in some cases excess mucus pooling. In globus without LPR, the larynx may appear entirely normal — which is itself a useful and reassuring finding.
Neck Examination
Palpation of the neck to assess the thyroid gland and exclude a structural cause for the throat sensation.
Further Investigations
Where the diagnosis is uncertain, or where LPR is suspected but has not responded to initial treatment, further investigation may include:
Dual-probe pH-impedance testing — the gold standard investigation for LPR, measuring both acid and non-acid reflux episodes over a 24-hour period and correlating them with symptoms
Barium swallow — to assess the oesophagus and exclude structural abnormalities
CT scanning — where a structural cause for globus is suspected and has not been excluded on clinical examination
Treatment of LPR
Dietary and Lifestyle Modification
This is the foundation of LPR management and should be implemented consistently regardless of whether medication is also used. Key measures include:
Avoiding the dietary triggers listed above
Eating smaller, more frequent meals
Not eating within three hours of lying down
Elevating the head of the bed by 10 to 15 centimetres
Reducing alcohol and caffeine intake
Stopping smoking
Weight reduction if relevant
Many patients with mild LPR achieve significant symptom improvement with dietary and lifestyle changes alone, without requiring medication.
Medication
Proton pump inhibitors (PPIs) — such as omeprazole or lansoprazole — reduce acid production and are the standard medical treatment for LPR. It is important to understand that LPR typically takes longer to respond to treatment than heartburn — often eight to twelve weeks of consistent medication and lifestyle modification before meaningful improvement is seen. This is because laryngeal tissue heals more slowly than oesophageal tissue.
Alginates — such as Gaviscon — form a protective raft on top of stomach contents and can help prevent reflux, particularly after meals and before bed.
H2 blockers — an alternative or adjunct to PPIs in some patients.
Voice Therapy
Where muscle tension is contributing to globus or voice symptoms, targeted exercises with a speech and language therapist can reduce laryngeal tension and improve symptoms.
Reassurance and Psychological Support
For patients in whom anxiety is a significant driver of globus, understanding the benign nature of the condition — confirmed by a normal laryngoscopy — is itself therapeutic. Cognitive behavioural approaches can help break the cycle of throat-focused anxiety that perpetuates the sensation.
When Is Globus Serious?
The vast majority of patients with globus have a benign underlying cause. However, certain features warrant more urgent assessment to exclude a structural or malignant cause:
True dysphagia — difficulty or pain on swallowing, food sticking, or progressive difficulty — always warrants investigation
Unintentional weight loss — in combination with throat symptoms, this requires prompt assessment
Persistent hoarseness lasting more than two to three weeks
Blood in saliva or phlegm
Symptoms in a patient with a significant smoking or alcohol history
If any of these features are present, the threshold for investigation should be low and the assessment prompt.
Frequently Asked Questions
Can globus go away on its own?
Yes — in many patients, particularly those in whom stress or a recent viral illness is the precipitant, globus resolves spontaneously over weeks to months. However, if it persists beyond a few weeks, is worsening, or is causing significant anxiety, an assessment is worthwhile.
I have been told I have LPR but I have no heartburn — is that possible?
Yes, absolutely. The absence of heartburn does not exclude LPR. The throat is far more sensitive to reflux than the oesophagus, and many patients with significant LPR never experience heartburn at all.
How long does LPR treatment take to work?
Typically eight to twelve weeks of consistent treatment — both medication and dietary modification — before significant improvement. This is longer than most patients expect. It is important to persist with treatment rather than concluding it is not working after two to three weeks.
Will I need to take PPIs permanently?
Not necessarily. Many patients with LPR can step down or stop medication once symptoms are controlled and lifestyle modifications are in place. Others require longer-term treatment. This is reviewed at follow-up.
Is there surgery for LPR?
Anti-reflux surgery (fundoplication) is occasionally considered for patients with severe, confirmed LPR that has not responded to maximal medical and lifestyle management. It is not a first-line treatment and requires careful patient selection.
Book an Assessment
If you have a persistent lump in the throat, chronic throat clearing, or other symptoms that may suggest globus or LPR, a specialist assessment can clarify the cause and guide appropriate treatment.
