Globus pharyngeus
The sensation of a lump in the throat — or a feeling that something is stuck, caught, or sitting in the throat that will not clear — is one of the most common reasons patients are referred to an ENT specialist. It causes significant anxiety because most people’s first thought is that it might represent cancer. In the overwhelming majority of cases it does not. The diagnosis is globus pharyngeus — a symptom, not a disease — defined as the persistent or intermittent sensation of a lump or foreign body in the throat in the absence of any structural cause.
That said, a small number of patients with this symptom do have a structural cause that requires treatment, which is why ENT assessment is appropriate rather than simply reassurance from a GP.
How Common Is It?
Globus pharyngeus is extremely common — estimates suggest that approximately half the population will experience the sensation at some point in their lives. It tends to occur during or following periods of stress, after a respiratory illness with prolonged coughing, or without any obvious precipitant. The median duration once it develops is around two years, though it can resolve within weeks or persist for longer. It is not related to swallowing difficulty — patients with globus pharyngeus can swallow normally and the sensation is typically absent or reduced during eating and drinking.
Causes
The most common identifiable cause is laryngopharyngeal reflux — acid from the stomach refluxing up into the throat, causing inflammation of the laryngeal and pharyngeal mucosa. This is often called “silent reflux” because many patients have no heartburn and no awareness of acid reflux — the lump sensation is their only symptom. The reflux irritates the posterior larynx and hypopharynx and produces a sensation of something sitting at that level.
The second common cause is habitual throat clearing. Frequent throat clearing — often an anxiety-driven or habitual behaviour — causes repeated mechanical irritation of the vocal cords and the surrounding tissues. The resulting swelling and inflammation produces the very sensation that drives more throat clearing, perpetuating a cycle that can persist for months. Recognising and stopping the throat clearing habit is often the most important part of treatment.
Other causes that need to be considered and excluded include enlarged or inflamed tonsils, thyroid gland enlargement or nodules, enlarged lymph nodes in the neck, benign cysts and mucosal lesions, salivary gland problems, pharyngeal or oesophageal motility issues, and — rarely — pharyngeal or oesophageal cancer. The symptom of a lump in the throat from cancer is usually associated with other features: progressive dysphagia (difficulty swallowing), odynophagia (painful swallowing), weight loss, hoarseness, or a visible or palpable neck mass. Isolated globus without these features is very rarely the presentation of malignancy.
Assessment
Assessment involves a careful history of the symptom — its onset, character, any associated symptoms, and any precipitating factors — followed by examination of the head and neck including fibreoptic laryngoscopy. This involves passing a thin flexible telescope through the nose to visualise the lower throat, the larynx, and the vocal cords. The procedure takes a few minutes, is well tolerated, and provides direct visualisation of the structures most commonly responsible for the symptom.
If laryngoscopy identifies a structural abnormality, further investigation is arranged as appropriate. If laryngoscopy and examination are normal, the diagnosis of globus pharyngeus is confirmed and management is directed at the likely underlying functional cause — most commonly reflux management and throat clearing habit modification.
Imaging (CT or MRI of the neck) is not routinely required for isolated globus pharyngeus but may be arranged if clinical assessment raises specific concerns about structures not visible on endoscopy.
Management
Where laryngopharyngeal reflux is the likely cause, management typically involves dietary modification (reducing acidic, fatty, and carbonated foods and drinks, caffeine, and alcohol), avoiding eating within two to three hours of lying down, and elevating the head of the bed. A trial of proton pump inhibitor therapy is often recommended and may be prescribed by your GP or at consultation. Response to reflux treatment can take several weeks to assess.
Where habitual throat clearing is a contributing factor, the key intervention is awareness and substitution — replacing the throat clearing habit with a hard swallow or a sip of water, which clears the throat without the mechanical irritation. Voice therapy with a speech pathologist can be helpful in establishing this habit change, particularly in patients who have developed the habit over a long period.
For most patients, reassurance that no serious cause has been found — combined with appropriate management of reflux or throat clearing — leads to significant improvement or resolution over weeks to months. Some patients have persistent symptoms despite treatment; in these cases, ongoing monitoring rather than escalating investigation is usually appropriate.
Dr Roth’s Clinical Perspective
Globus is one of those presentations where the most important thing I do is the laryngoscopy — not because I expect to find something sinister, but because the patient needs to see that I have looked properly. Telling someone their throat is normal after examining their mouth and neck from the outside does not have the same reassurance value as showing them a normal laryngoscopy. Most patients who have been worried about throat cancer find that seeing their larynx on screen and being told it is normal is genuinely reassuring in a way that a clinical opinion alone cannot provide.
The other thing worth emphasising is throat clearing. It is one of the most self-perpetuating behaviours in ENT — patients clear their throat because it feels uncomfortable, the clearing causes more irritation, and the irritation makes them clear again. Breaking that cycle is often more therapeutically useful than any medication. I explain this mechanism at every consultation because patients who understand why they need to stop find it easier to stop.
