Introduction

Globus, historically referred to as "globus pharyngeus" or "globus hystericus," is a persistent or intermittent, nonpainful sensation of a lump, foreign body, or tightness in the throat. It is one of the most commonly encountered symptoms in otolaryngology and gastroenterology practices, accounting for up to 4% of new ENT referrals and affecting an estimated 45% of the general population at some point in their lifetime. Despite its prevalence, globus remains a diagnosis of exclusion, requiring systematic evaluation to rule out structural, inflammatory, reflux-mediated, and motility-related causes before a functional label is applied.

Under the Rome IV classification system (2016), globus is categorized as a functional esophageal disorder (category A4). The Rome IV framework provides standardized diagnostic criteria that allow clinicians to identify the condition with reasonable confidence once appropriate investigations have been completed. This article examines the Rome IV criteria for globus in detail, discusses the recommended diagnostic workup, explores the current understanding of pathophysiology, and reviews management approaches supported by the available evidence.

Historical Context and Terminology

The term "globus hystericus" dates to antiquity, when the sensation was attributed to the wandering uterus in women, a concept rooted in Hippocratic medicine. By the mid-20th century, the association with hysteria was recognized as inaccurate, and the term was revised to "globus pharyngeus" to reflect a more anatomically neutral description. The Rome classification system further shifted the nomenclature to simply "globus" in recognition that the sensation does not always localize to the pharynx and that it belongs within the spectrum of functional esophageal disorders.

Rome I (1994) first included globus among functional esophageal disorders. Rome II (1999) refined the definition by requiring that the sensation occur between meals and that dysphagia be absent. Rome III (2006) added the requirement for absence of a histopathologic mucosal abnormality such as gastroesophageal reflux disease (GERD) as the cause. Rome IV (2016) introduced the most significant update by explicitly incorporating the gastric inlet patch as an exclusionary finding and by requiring the absence of eosinophilic esophagitis (EoE) alongside GERD. These additions reflect advances in endoscopic detection and the growing recognition that both inlet patches and EoE can produce globus-like symptoms.

Rome IV Diagnostic Criteria for Globus (A4)

The Rome IV criteria for globus require that all of the following be present. Additionally, these criteria must be fulfilled for the past 3 months, with symptom onset at least 6 months before diagnosis and a frequency of at least once per week.

Criterion 1: Persistent or Intermittent Nonpainful Sensation of a Lump or Foreign Body in the Throat

The cardinal feature of globus is a subjective sensation of something lodged in the throat, typically described as a lump, ball, tightness, or foreign body. Patients commonly localize it to the midline, between the thyroid cartilage and the suprasternal notch. The sensation is explicitly nonpainful; the presence of pain should redirect the diagnostic evaluation toward other entities including odynophagia-associated conditions, cricopharyngeal spasm, or referred pain from cervical spine disease.

Importantly, there must be no structural lesion identified on physical examination, laryngoscopy, or endoscopy. This requirement underscores that globus is fundamentally a diagnosis of exclusion. Physical examination of the neck and oropharynx, flexible nasopharyngolaryngoscopy, and upper endoscopy (esophagogastroduodenoscopy, or EGD) should be performed as clinically indicated to exclude masses, webs, strictures, Zenker diverticulum, thyroid enlargement, cervical lymphadenopathy, and other structural pathology.

Sub-criterion 1a: Occurrence of the Sensation Between Meals

Rome IV specifies that the globus sensation must occur between meals. This temporal pattern helps distinguish globus from conditions in which symptoms are predominantly provoked by eating or swallowing, such as functional dyspepsia, esophageal strictures, or eosinophilic esophagitis. Many patients with globus report that eating or swallowing actually provides temporary relief, which is a useful clinical clue. If symptoms worsen during meals or are consistently meal-related, alternative diagnoses should be pursued.

Sub-criterion 1b: Absence of Dysphagia or Odynophagia

True dysphagia (difficulty initiating or completing a swallow) and odynophagia (painful swallowing) are alarm features that should prompt a targeted investigation for structural or inflammatory esophageal disease. Oropharyngeal dysphagia may indicate neuromuscular causes including stroke, myasthenia gravis, or Parkinson disease, while esophageal dysphagia raises concern for strictures, rings, webs, malignancy, or eosinophilic esophagitis. The absence of these symptoms is required to apply the globus label under Rome IV.

It is worth noting that patients with globus sometimes describe a subjective "difficulty swallowing" that, on careful questioning, reflects the sensation of the lump itself rather than true mechanical or propulsive dysphagia. Eliciting this distinction during the clinical interview is important to avoid unnecessary alarm while still conducting appropriate workup.

Sub-criterion 1c: Absence of a Gastric Inlet Patch in the Proximal Esophagus

The gastric inlet patch (also called cervical inlet patch or heterotopic gastric mucosa) is an island of columnar gastric-type epithelium found in the proximal esophagus, typically within 1 to 3 cm distal to the upper esophageal sphincter. Prevalence estimates range widely (1% to 10% in endoscopic studies), likely reflecting variation in how carefully the proximal esophagus is inspected during routine EGD.

Rome IV explicitly added the gastric inlet patch as an exclusionary criterion because acid secretion from these patches may produce localized mucosal irritation and globus-like symptoms. Studies have demonstrated that patients with symptomatic inlet patches can experience relief with proton pump inhibitor therapy or, less commonly, endoscopic ablation. When an inlet patch is identified at endoscopy and is thought to be clinically relevant, the globus label under Rome IV should not be applied until the contribution of the patch to symptoms has been assessed.

Criterion 2: Absence of Evidence That Gastroesophageal Reflux or Eosinophilic Esophagitis Is the Cause of the Symptom

GERD has long been implicated as a potential contributor to globus, with early studies suggesting that up to 25% to 68% of globus patients have abnormal esophageal acid exposure. However, the relationship between reflux and globus is complex, and Rome IV does not assert causation but rather requires that reflux or EoE be excluded as the cause of the throat sensation before a functional diagnosis is made.

In practice, this criterion is typically addressed through:

• Empiric proton pump inhibitor (PPI) trial: A 4- to 8-week course of once- or twice-daily PPI therapy is commonly employed as an initial step when reflux is clinically suspected. If symptoms resolve completely with PPI therapy and recur upon discontinuation, reflux is considered a likely etiology and the globus label does not apply.
• Upper endoscopy with esophageal biopsies: EGD allows direct visualization of the esophageal mucosa to identify erosive esophagitis, Barrett esophagus, eosinophilic infiltration (at least 15 eosinophils per high-power field in mucosal biopsies), and other mucosal abnormalities. When EoE is confirmed, treatment directed at EoE should be initiated before considering a functional diagnosis.
• Ambulatory reflux monitoring: In patients with persistent symptoms despite a PPI trial and a normal endoscopy, ambulatory pH monitoring (catheter-based or wireless) or combined pH-impedance testing can objectively assess acid and non-acid reflux burden. A normal reflux study in the setting of negative endoscopy and failed PPI trial provides strong evidence against reflux as the cause, supporting the functional diagnosis.

Criterion 3: Absence of Major Esophageal Motor Disorders

The final diagnostic criterion requires that major esophageal motor disorders be excluded, typically through high-resolution manometry (HRM). The specific conditions that must be absent are defined by the Chicago Classification (version 3.0 at the time of Rome IV publication, now updated to version 4.0):

• Achalasia (types I, II, and III) and esophagogastric junction (EGJ) outflow obstruction: These disorders impair relaxation of the lower esophageal sphincter and can produce symptoms including dysphagia, chest pain, and regurgitation. While globus is primarily a throat-level sensation, disordered esophageal motility can produce referred sensations that mimic or overlap with globus.
• Diffuse esophageal spasm (DES): Characterized by premature contractions in at least 20% of swallows on HRM, DES can cause chest pain and dysphagia that may be confused with or coexist alongside globus.
• Jackhammer esophagus (hypercontractile esophagus): Defined by at least 20% of swallows with a distal contractile integral (DCI) greater than 8,000 mmHg-cm-s, this condition may be associated with chest pain or dysphagia.
• Absent peristalsis: Complete failure of esophageal peristalsis, often seen in systemic sclerosis, must be ruled out.

It is important to note that minor or borderline manometric findings, such as ineffective esophageal motility (IEM) or fragmented peristalsis, do not meet the threshold for "major" motor disorders and are compatible with a functional diagnosis when the clinical picture is consistent with globus.

Temporal Criteria

Rome IV applies standardized temporal requirements to all functional gastrointestinal diagnoses, and globus is no exception:

• Duration: Symptoms must have been present for at least the last 3 consecutive months.
• Onset: The initial symptom onset must have occurred at least 6 months before the diagnosis is made.
• Frequency: The sensation must occur on average at least once per week.

These temporal thresholds serve to distinguish chronic, recurring functional symptoms from transient or self-limited sensations that may occur in response to acute illness, emotional stress, or situational anxiety. A patient who has experienced intermittent throat fullness for only a few weeks following an upper respiratory infection, for example, would not meet the temporal criteria even if all diagnostic criteria were satisfied.

Epidemiology

Globus is remarkably common. Community-based surveys estimate that 45% of otherwise healthy individuals have experienced the sensation at some point, though only a fraction seek medical attention. Among those who do present to healthcare providers, globus is slightly more common in women, with most studies reporting a female-to-male ratio of approximately 1.5:1 to 3:1. The peak age at presentation is typically between 40 and 60 years, though the condition can occur at any age.

Globus accounts for approximately 4% of new referrals to otolaryngology clinics and is among the top five functional esophageal diagnoses encountered in gastroenterology practice. Despite its high prevalence, many patients go undiagnosed or are assigned nonspecific labels such as "pharyngeal discomfort" or "throat tightness" because the systematic Rome IV evaluation is not always applied in routine practice.

Pathophysiology

The pathophysiology of functional globus remains incompletely understood, though several mechanisms have been proposed, and it is likely that the condition is multifactorial in most patients.

Visceral Hypersensitivity

Heightened sensitivity of the esophageal and pharyngeal mucosa to normal physiologic stimuli is considered a central mechanism. Balloon distention studies have demonstrated that patients with globus perceive esophageal distention at lower thresholds than healthy controls. This visceral hypersensitivity may arise from peripheral sensitization (increased afferent nerve firing) or central sensitization (augmented processing of visceral signals in the brainstem and cortex).

Upper Esophageal Sphincter Dysfunction

Abnormalities in upper esophageal sphincter (UES) tone and coordination have been reported in some patients with globus. Elevated basal UES pressure, incomplete UES relaxation, and abnormal cricopharyngeal muscle activity have all been documented, though findings are inconsistent across studies. Some investigators have proposed that heightened UES tone represents a protective reflex against perceived (but not actual) reflux, while others suggest it is a primary motor abnormality.

Psychosocial Factors

There is a well-established association between globus and psychological comorbidity. Anxiety, depression, somatization, and stressful life events are more prevalent in patients with globus compared to controls. Functional neuroimaging studies have shown altered activation in brain regions involved in visceral sensory processing, emotion regulation, and interoception (including the anterior cingulate cortex, insula, and prefrontal cortex) in patients with functional esophageal disorders. Whether psychological factors are causative, contributory, or consequential remains debated, but their presence significantly influences symptom severity and treatment response.

Mucosal Inflammation and Reflux

While overt GERD must be excluded as the cause of symptoms under Rome IV, subclinical inflammation or non-acid reflux events may play a contributory role in some patients with functional globus. Studies using multichannel intraluminal impedance monitoring have detected weakly acidic or non-acid reflux reaching the proximal esophagus in a subset of patients who would not be identified by pH monitoring alone. The clinical significance of these findings remains uncertain, and they do not meet the threshold for reclassifying the diagnosis as GERD.

Musculoskeletal and Postural Contributions

Tension in the strap muscles of the neck, temporomandibular joint dysfunction, cervical spine disorders, and habitual throat clearing or excessive swallowing have all been suggested as peripheral contributors to the globus sensation. Speech-language pathologists and physiotherapists have noted that postural retraining and laryngeal massage can alleviate symptoms in selected patients, supporting a musculoskeletal component in at least some cases.

Recommended Diagnostic Workup

There is no single definitive test for globus; the diagnosis is established by fulfilling Rome IV criteria after appropriate exclusionary investigations. The workup should be tailored to the individual patient based on symptom severity, associated features, and clinical suspicion for alternative diagnoses.

Initial Assessment

• Thorough history: Characterize the sensation (location, timing, relieving and aggravating factors), inquire about dysphagia, odynophagia, weight loss, voice changes, and heartburn. Assess psychological well-being and stressful life events.
• Physical examination: Examine the oropharynx, neck (thyroid, lymph nodes), and assess for cervical spine tenderness or limited range of motion.
• Flexible nasopharyngolaryngoscopy: Performed by an otolaryngologist or trained clinician to evaluate the nasopharynx, oropharynx, hypopharynx, and larynx for structural or inflammatory pathology. This is often the first investigation in patients who present initially to ENT services.

Endoscopic Evaluation

• Esophagogastroduodenoscopy (EGD): Recommended to evaluate the esophageal mucosa, identify or exclude erosive esophagitis, Barrett esophagus, eosinophilic esophagitis (with biopsies from the proximal and distal esophagus), gastric inlet patch in the proximal esophagus, strictures, rings, webs, and masses. Careful inspection of the proximal esophagus within the first few centimeters below the UES is important to identify inlet patches, which may be overlooked during routine endoscopy if the scope is withdrawn quickly.

Reflux Testing

• Empiric PPI trial: Often the initial step for patients with concurrent heartburn or regurgitation. A 4- to 8-week trial of standard- or double-dose PPI is recommended before invasive reflux testing.
• Ambulatory pH or pH-impedance monitoring: Indicated when the PPI trial is non-diagnostic, symptoms persist despite acid suppression, or objective documentation of reflux is needed. pH-impedance testing can detect both acid and non-acid reflux events.

Esophageal Manometry

• High-resolution manometry (HRM): Recommended to evaluate esophageal body peristalsis and lower esophageal sphincter function, primarily to exclude the major motor disorders specified in criterion 3 (achalasia, EGJ outflow obstruction, DES, jackhammer esophagus, absent peristalsis). HRM also provides information about UES function, though interpretation of UES metrics is less standardized.

Additional Investigations

• Barium swallow: May be useful when there is concern for subtle structural abnormalities not well characterized by endoscopy, such as small Zenker diverticula, cricopharyngeal bars, or extrinsic compression.
• Thyroid function tests and neck ultrasound: Considered when thyroid enlargement is detected on examination or when thyroid disease is suspected.
• Psychological screening: Tools such as the Hospital Anxiety and Depression Scale (HADS) or Patient Health Questionnaire (PHQ-9) can identify comorbid psychological conditions that may inform treatment planning.

Differential Diagnosis

The differential diagnosis of a persistent throat sensation is broad and includes conditions that must be systematically excluded before applying the Rome IV globus criteria:

Category	Conditions
Structural / Anatomic	Pharyngeal or esophageal tumors, Zenker diverticulum, cricopharyngeal bar, cervical osteophytes, thyroid goiter, cervical lymphadenopathy, esophageal web or ring, post-cricoid web (Plummer-Vinson syndrome)
Inflammatory / Infectious	Eosinophilic esophagitis, pharyngitis, tonsillitis, epiglottitis, laryngopharyngeal reflux (LPR), gastric inlet patch with local acid production
Gastroesophageal Reflux	Erosive esophagitis, non-erosive reflux disease (NERD), extraesophageal reflux syndromes
Motor Disorders	Achalasia, EGJ outflow obstruction, diffuse esophageal spasm, jackhammer esophagus, absent peristalsis, cricopharyngeal dysfunction
Neurologic	Stroke with pharyngeal involvement, myasthenia gravis, Parkinson disease, multiple sclerosis, amyotrophic lateral sclerosis
Psychological	Anxiety disorders, panic disorder, somatoform disorder, health anxiety (hypochondriasis)
Other	Post-nasal drip, allergic rhinitis, vocal cord dysfunction, medication-related (e.g., pill esophagitis, bisphosphonate-induced), foreign body

Management Strategies

Once a diagnosis of functional globus has been established under the Rome IV framework, management focuses on symptom relief, patient education, and addressing contributing factors. Evidence from large randomized controlled trials is limited, and most recommendations are based on small studies, case series, and expert consensus.

Reassurance and Patient Education

For many patients, the most impactful intervention is a clear, empathetic explanation that the symptom does not indicate cancer, stricture, or other serious pathology. Studies have demonstrated that structured reassurance, ideally after a thorough workup has been completed, can reduce symptom severity and healthcare utilization. Patients should be informed that globus is a recognized, well-described condition, that it is common, and that it does not carry a malignant potential. Naming the condition and validating the symptom as real (rather than dismissing it as psychosomatic) is an essential therapeutic step.

Dietary and Lifestyle Modifications

While not specifically studied in globus, general measures to reduce potential reflux contribution are often recommended:

• Avoidance of large meals before lying down
• Elevation of the head of the bed if nocturnal symptoms are present
• Reduction of caffeine, alcohol, and carbonated beverages
• Adequate hydration and avoidance of excessive throat clearing
• Stress reduction techniques including mindfulness-based stress reduction, diaphragmatic breathing, and progressive muscle relaxation

Acid Suppression Therapy

Despite the requirement that GERD be excluded under Rome IV, a short empiric trial of PPI therapy is frequently administered during the diagnostic phase. In patients with borderline or equivocal reflux findings, a PPI trial may serve both diagnostic and therapeutic purposes. However, long-term PPI therapy is not recommended for functional globus in the absence of objective reflux, given the lack of evidence for benefit and the potential for adverse effects associated with prolonged acid suppression.

Neuromodulator Therapy

Central neuromodulators are increasingly recognized as a treatment option for functional esophageal disorders, including globus, particularly when symptoms are moderate to severe or refractory to initial measures:

• Tricyclic antidepressants (TCAs): Low-dose amitriptyline or nortriptyline (10 to 50 mg at bedtime) has been used with some reported success. TCAs modulate visceral pain processing through effects on serotonin and norepinephrine reuptake and may also reduce esophageal hypersensitivity.
• Selective serotonin reuptake inhibitors (SSRIs) and serotonin-norepinephrine reuptake inhibitors (SNRIs): Agents such as sertraline, citalopram, or duloxetine may be considered, particularly when comorbid anxiety or depression is present.
• Gabapentinoids: Gabapentin and pregabalin have shown benefit in small studies of functional esophageal symptoms, likely through modulation of central and peripheral sensitization pathways. They may be particularly useful when the globus sensation has a neuropathic quality.

Behavioral and Psychological Therapies

Given the association between globus and psychological distress, cognitive behavioral therapy (CBT) and other psychotherapeutic approaches may be beneficial:

• Cognitive behavioral therapy: CBT has the strongest evidence base among psychological interventions for functional gastrointestinal disorders. It helps patients identify and modify maladaptive thought patterns and behaviors that perpetuate symptom perception and distress.
• Hypnotherapy: Gut-directed hypnotherapy has demonstrated efficacy in irritable bowel syndrome and functional dyspepsia, and preliminary data suggest it may also help in esophageal functional disorders, though data specific to globus are sparse.
• Mindfulness-based therapies: Mindfulness meditation and acceptance-based approaches may reduce symptom severity by altering the relationship between the patient and the symptom rather than attempting to eliminate the sensation.

Speech and Language Therapy

Speech-language pathologists (SLPs) with expertise in voice and swallowing disorders can address musculoskeletal contributors to globus through:

• Laryngeal manual therapy and circumlaryngeal massage to reduce perilaryngeal muscle tension
• Vocal hygiene counseling to reduce habitual throat clearing and coughing
• Breathing retraining to address paradoxical vocal fold motion or laryngeal hyperresponsiveness
• Postural correction and relaxation exercises targeting the head, neck, and shoulders

Small studies have reported symptom improvement in 50% to 80% of patients who undergo structured SLP-directed therapy, suggesting this modality may be underutilized in current clinical practice.

Combination and Step-Up Approach

In clinical practice, a stepwise approach is often used:

1. Complete the Rome IV diagnostic workup and provide structured reassurance.
2. Address modifiable lifestyle factors, discontinue unnecessary throat clearing, and recommend stress management techniques.
3. Initiate a time-limited PPI trial if residual reflux concern exists.
4. If symptoms persist, consider low-dose neuromodulator therapy tailored to the patient's comorbidity profile.
5. Refer for behavioral therapy (CBT, hypnotherapy) or speech-language therapy for refractory symptoms.
6. Reassess periodically and consider repeat investigation if new alarm features develop.

Special Considerations

Overlap with Other Functional Esophageal Disorders

Functional esophageal disorders frequently overlap. Patients with globus may concurrently meet criteria for functional heartburn, reflux hypersensitivity, or functional chest pain. Rome IV recognizes that a single patient may carry multiple functional diagnoses, and the presence of one does not exclude another. Clinicians should evaluate each symptom domain independently and apply the appropriate criteria set for each.

Globus in the Elderly

In older adults, the threshold for structural investigation should be lower, as the incidence of esophageal and pharyngeal malignancy increases with age. Cervical osteophytes causing extrinsic esophageal compression are also more common in elderly populations and can produce a globus-like sensation. Sarcopenia-related changes in pharyngeal and esophageal muscle function may further complicate the clinical picture.

Globus Following Endotracheal Intubation or Surgical Procedures

Post-procedural globus is not uncommon following prolonged endotracheal intubation, anterior cervical spine surgery, or thyroid surgery. These cases may represent transient mechanical or inflammatory injury to the pharynx or larynx rather than functional globus. The Rome IV temporal criteria (6-month onset requirement) help distinguish chronic functional globus from post-procedural symptoms, which typically resolve within weeks to months.

When to Revisit the Diagnosis

A diagnosis of functional globus should be revisited if new symptoms emerge, including progressive dysphagia, unintentional weight loss, hematemesis, persistent hoarseness, or palpable neck mass. These alarm features warrant repeat investigation regardless of a prior functional diagnosis. Additionally, if initial testing was limited (for example, if manometry was not performed), completing the workup at a later date may be warranted when symptoms persist despite standard management.

Prognosis and Natural History

The natural history of globus is variable. Longitudinal studies suggest that approximately 50% to 75% of patients experience spontaneous improvement or resolution over a follow-up period of 3 to 7 years. However, a substantial minority (25% to 50%) report persistent or intermittent symptoms over the long term. Predictors of persistent symptoms include comorbid psychological distress, longer symptom duration before diagnosis, and the presence of concurrent functional gastrointestinal disorders. Importantly, the development of esophageal or pharyngeal malignancy in patients with a well-established diagnosis of functional globus is exceedingly rare, and repeated invasive investigation in the absence of new alarm features is generally not warranted.
