REFERENCE · DIAGNOSIS

Functional Swallowing Symptoms and Globus

Refers to:

functional difficulty swallowing food, drink or saliva;
difficulty initiating a swallow or a feeling that material sticks; and
globus: a lump or tightness sensation, typically between swallows.

Scope boundary: Not every cough, choking episode or breathing symptom is functional dysphagia. Mouth closure may also need facial assessment, while cough and laryngeal symptoms have a separate page. Technique choice follows whether the problem is swallowing, globus, mouth control or airway protection.

Featured technique: Structured swallowing history and clinical assessment, with instrumental assessment when indicated.
Diagnostic method: Distinguish swallowing impairment from globus, look for a positive functional pattern and investigate structural or neurological alternatives.
Media needed: A clinician explanation or a consented, annotated FEES or videofluoroscopy excerpt—not a contributor-designed food challenge.

Diagnostic techniques at a glance

These brief entries describe signs, observations, criteria and investigations clinicians may consider. They are not a checklist of tests everyone needs. Evidence and limitations differ for each entry; a positive sign must fit the whole clinical picture, including possible coexisting disease.

The longer explanations already on this page remain below. Individual technique pages will be developed and reviewed separately.

Clinical swallowing assessment

The clinician distinguishes mouth/throat swallowing difficulty from oesophageal symptoms and reviews safety, nutrition and examination findings. A specific task inconsistency can contribute to a formulation, but a normal bedside examination cannot exclude aspiration or other swallowing disease. [1][2]

Cross-task swallowing comparison

Swallowing behaviour is compared across clinically appropriate contexts, including spontaneous and requested actions. A reproducible mismatch may be informative. Different textures or volumes are only used within an assessed safety plan; variability is not a standalone FND sign. [1]

FEES

A flexible endoscope evaluates pharyngeal swallowing and airway protection. Findings can identify impairment or preserved function for tested conditions. This is a differential and safety investigation, not an independent positive test for functional dysphagia. [1][2]

Videofluoroscopic swallowing study

Moving X-ray images assess bolus movement and aspiration during selected swallows. The study can identify structural or physiological problems and guide safe interpretation of symptoms. Normal sampled swallows do not automatically establish a functional diagnosis. [1][2]

Rome criteria for functional dysphagia

Formal oesophageal criteria require a characteristic sticking or passage complaint and evaluation for structural, mucosal, reflux-related and major motility causes. These are consensus criteria for an oesophageal disorder, not simply a positive motor-FND sign. [3]

Rome criteria for globus

Globus describes a non-painful lump or foreign-body sensation, usually between meals, without dysphagia or painful swallowing in the defined syndrome. Required duration and differential assessment matter; a persistent lump sensation is not automatically FND. [3]

Endoscopy, biopsy and oesophageal physiology

Selected endoscopy, mucosal sampling, manometry or reflux testing investigate plausible alternative explanations. These are differential tests. Findings and symptoms must be interpreted together; a series of normal results is not itself a positive functional sign. [3]

Dysphagia means difficulty moving food, drink or saliva safely and efficiently. Globus is a feeling of a lump or tightness in the throat that is usually noticed between swallows rather than food becoming stuck. They can overlap, but they are not the same symptom and should not be treated as interchangeable.

A speech-and-language therapist or another appropriately trained clinician takes a detailed history and observes swallowing when it is safe. Some people need an instrumental study such as fibreoptic endoscopic evaluation of swallowing (FEES) or videofluoroscopy. A functional diagnosis is based on the overall positive pattern, not simply on a normal scan or scope. [1]

Swallowing and throat symptoms can fluctuate

Functional swallowing difficulty or globus may be intermittent, vary from one part of a meal or setting to another, occur in flares, or remain persistent. The pattern may change with texture, attention, fatigue, pain, throat tension or other symptoms. Because swallowing has airway and nutrition consequences, a change in timing does not make it safe to experiment with difficult foods.

If familiar difficulty begins during eating or drinking, follow the person’s assessed swallowing plan. Stop the meal when the current swallow is not safe, remain in the recommended position, and use only a strategy or texture already approved for that person. Do not use distraction as an emergency technique unless the treating clinician has specifically established it as safe. Choking, inability to swallow saliva, breathing difficulty or a substantially changed pattern needs appropriate urgent assessment.

Weight loss, dehydration, recurrent chest infection, progressive difficulty, pain, bleeding or other concerning features need appropriate medical investigation. Do not test your swallowing with increasingly difficult foods at home.

Follow the person’s current swallowing plan, including recommended texture, position, pace and supervision. Do not offer a difficult food or large drink to see whether the symptom changes with distraction. If choking or another emergency occurs, follow local emergency guidance and the person’s care plan.

Useful observations include which consistencies are difficult, whether the problem is before, during or after the swallow, and whether coughing, wet voice, pain or food sticking occurs. Pass these observations to the clinical team without trying to diagnose them.

When a swallowing episode starts

An intermittent problem can still carry real choking, aspiration or nutrition risk. Stop adding new food or drink until the person is following their established plan. Keep the environment calm, but do not encourage extra swallows, large sips or an unapproved texture to make the symptom pass. If the person has a clinician-taught posture, pacing or release strategy, support that exact plan.

Record duration and meal context only after immediate swallowing and breathing safety has been addressed.

Episodic and prolonged presentations

Characterize whether dysphagia, globus or choking fear is persistent, intermittent or meal/context-specific. Record episode duration, consistency and volume, time within the meal, associated respiratory/voice symptoms, nutritional effect, warning and recovery. Fluctuation can be clinically informative but does not establish functional dysphagia and does not remove the need for appropriate airway, neurological and structural assessment.

For an established episodic functional pattern, define a short onset plan that states what intake remains safe, when to stop, which clinician-selected posture, pacing, attention or relaxation strategy may be used, and when reassessment or emergency action is required. Avoid using food challenges to provoke an attack for diagnostic demonstration.

Technique outline: functional swallowing assessment

Establish whether the complaint is dysphagia, globus, choking fear, pain, regurgitation or another sensation. Document onset, course, consistency effects, nutrition, hydration and respiratory consequences.
Screen for urgent or progressive features and examine relevant cranial-nerve, voice, respiratory and neurological function.
Conduct a clinical swallowing evaluation using only consistencies and quantities that are justified and safe for the person. Observe oral preparation, swallow timing, laryngeal signs, voice change and recovery.
Arrange FEES, videofluoroscopy, endoscopy, imaging or other investigation when needed to assess safety, physiology or an identified differential.
Compare reported difficulty, observed performance and instrumental findings. Look for a coherent positive functional pattern, but do not infer functional dysphagia only because structural testing is normal.
Consider structural disease, neurological dysphagia, reflux, eosinophilic disease, medication effects, pain and avoidant/restrictive food intake according to the presentation.
Explain the conclusion and provide an eating, drinking and treatment plan. Reassess if nutrition, respiratory status or symptom pattern changes.

Media contributor brief

The safest contribution is a clinician-led explanation using a swallowing diagram. If instrumental media is available, use an existing, de-identified and specifically consented FEES or videofluoroscopy segment to identify anatomy and the question the study answers.

Do not ask a participant to swallow a chosen food, large bolus or difficult texture for public filming. Do not imply that a normal-looking swallow in one clip proves every meal is safe. The written page and narration must distinguish globus from dysphagia and include the need for individual safety guidance.

Recovery reading: Eleven detailed swallowing and globus pages explain individual selection and safety limits after assessment.
