Swallowing is something most of us take for granted—until it fails. Dysphagia—Dysphagia and swallowing difficulties—can profoundly impact quality of life, nutrition, health outcomes, and safety. In this post, we delve into the definition of dysphagia, explore its mechanisms and types, present real-world case studies, outline diagnostic and management strategies, and highlight emerging innovations. Our goal is to arm clinicians, caregivers, and stakeholders with insight into effective, evidence-based care for swallowing difficulties.
What Is Dysphagia & Why It Matters: Dysphagia and Swallowing Difficulties
Definition & prevalence
- Dysphagia refers to difficulty in any phase of swallowing (oral, pharyngeal, oesophageal).
- It is estimated that around 1 in 17 people will experience dysphagia at some point in life.
BMJ - In adults presenting to clinicians, it is a relatively common complaint that demands careful evaluation.

Why it matters: Dysphagia and swallowing difficulties
- Untreated dysphagia can lead to aspiration pneumonia, chronic malnutrition, dehydration, reduced quality of life, and increased mortality.
BMJ - For older patients and those with comorbidities, the stakes are higher.
- Because patients often mislocalise where the “sticking” occurs, a thorough diagnostic workup is essential.

Types, Mechanisms & Clinical Red Flags
Oropharyngeal vs Esophageal Dysphagia
- Oropharyngeal dysphagia: difficulty initiating a swallow, cough or choke during swallowing, nasal regurgitation. Common in neurological disease, stroke, muscle disease.
Wikipedia - Esophageal dysphagia: sensation of food “sticking” after initiation, often in the chest or behind the sternum. Causes include strictures, rings, motility disorders, malignancy.
BMJ
Gastro Endo News
Additional Mechanisms & Special Types
- Functional dysphagia: when patients report swallowing difficulty but no clear anatomical or instrumentally confirmed cause. It may involve psychological or sensory contributors.
Taylor & Francis Online - Sarcopenic dysphagia: muscle wasting (sarcopenia) affecting swallowing muscles can lead to dysphagia in frail populations.
Wikipedia - Radiation-induced dysphagia: in head and neck cancer survivors, radiation can damage muscles and nerves in the swallowing apparatus.
CGH Journal - Emerging work is exploring the use of machine learning to differentiate swallowing acoustics (normal vs dysphagic) via noninvasive sensors. Recent studies achieved ~83% accuracy.

Red Flags & Urgent Referral
When evaluating dysphagia in adults, urgent red flags include:
- Progressive dysphagia (worsening over weeks)
- Dysphagia for both solids and liquids
- Weight loss, anemia, gastrointestinal bleeding
- Voice changes, airway symptoms, neck mass
In adults with new-onset dysphagia, guidelines often recommend upper GI endoscopy within two weeks to exclude malignancy.
BMJ
Case Studies: Learning from Real Life
Case A: Adolescent with Functional Dysphagia
A 16-year-old girl developed difficulty swallowing solids and a globus sensation. Initial ENT and barium swallow were unremarkable. Over 1.5 years, she underwent evaluation by ENT, SLP, pediatrician, psychologist, and dietician. She was eventually diagnosed with functional dysphagia and treated using a cognitive-behavioral, multidisciplinary program.
DIVA Portal
This case highlights how a diagnosis of exclusion, multidisciplinary collaboration, and structured therapeutic planning are key in functional dysphagia.
Case B: 73-Year-Old Man with Progressive Solid Dysphagia
A 73-year-old male reported progressive intermittent difficulty swallowing solids over six months, with no weight loss or voice change. His evaluation and imaging workup focused on discerning structural or motility etiologies.
Mayo Clinic Proceedings
This scenario emphasises the importance of endoscopic and imaging diagnostics when esophageal dysphagia is suspected.
Case C: Role of Occupational Therapy in Acute Dysphagia Care
In an acute care hospital setting, an occupational therapist worked within a multidisciplinary team to provide swallowing evaluations and interventions—avoiding the need for a percutaneous endoscopic gastrostomy (PEG) tube. The OT addressed mealtime safety, oral hygiene, and feed modifications, and improved outcome via collaboration.
Acute Care OT Journal
This case underscores that swallowing care is not solely the domain of speech pathologists—other allied health professionals play critical roles.
Diagnostic Pathway & Best Practices
1. History & clinical examination
- Onset (acute vs chronic), progression
- Associated symptoms (weight loss, regurgitation, cough)
- Neurological or systemic disease history
- Use validated screening tools (e.g. EAT-10 questionnaire
2. Bedside swallowing assessment
- Oral motor exam, bolus trials, observation of cough/choking
- Medasyst can assist with Dysphagia and swallowing difficulties
3. Instrumental testing
- Videofluoroscopic Swallow Study (VFSS / modified barium swallow)
- Fiberoptic Endoscopic Evaluation of Swallowing (FEES)
- High-resolution manometry, endoscopy, CT/MRI if indicated
- Some centers combine modalities for comprehensive evaluation.

4. Multidisciplinary review
- Involve ENT, gastroenterology, speech pathology, dietetics, occupational therapy, and psychology (if needed)
- Medasyst can assist with Dysphagia and swallowing difficulties
5. Tailored management plan (described below): Dysphagia and swallowing difficulties
Management & Intervention Strategies
Diet & Texture Modification
- Use of texture-modified diets (pureed, soft, thickened liquids) is standard to reduce risk of aspiration.
- Medasyst can assist with Dysphagia and swallowing difficulties
- Extensional rheology research suggests that the viscoelastic / extensional properties of liquids matter for bolus transport and residue; future dietetics may fine-tune liquid formulations accordingly.
arXiv - Universal systems like IDDSI (International Dysphagia Diet Standardisation Initiative) help standardise textures and thickness.
Wikipedia
Compensatory & Rehabilitation Techniques
- Postural maneuvers (e.g. head tilt, chin tuck)
- Swallowing maneuvers (e.g. effortful swallow, Mendelsohn maneuver)
- Strengthening exercises (e.g. Shaker exercise, tongue resistance training)
- Neuromuscular electrical stimulation (NMES) in appropriate cases
- Speech and language therapy supervision
Medical, Endoscopic & Surgical Options
- Dilation of strictures or webs
- Botox injection (for cricopharyngeal dysfunction)
- Surgical correction for anatomical lesions
- In head & neck cancer survivors, prophylactic swallowing exercises before radiation show promise
Nutritional Support & Monitoring
- Early dietetic input is essential to prevent malnutrition
- In severe cases, enteral feeding (NG tube, PEG) may be needed, but ideally as a temporary measure
Emerging & Future Technologies
- Sensor-based acoustic methods plus machine learning to noninvasively detect dysphagia (e.g. ~83% accuracy in distinguishing normal vs dysphagic swallows)
arXiv - 3D-printed food tailored to safe textures and high nutritional density is being piloted to improve palatability and safety for dysphagia patients.

Implementation Tips for Clinicians & Institutions
- Establish dysphagia teams or pathways (ENT, SLP, dietetics, OT)
- Educate staff on aspiration risk and feeding protocols
- Use validated screening tools to flag patients early
- Monitor outcomes: weight trajectory, pneumonia incidence, patient-reported swallowing quality
- Leverage telehealth: a recent pediatric telepractice pilot improved swallowing and quality-of-life metrics over 4 weeks.

Challenges, Gaps & Research Directions: Dysphagia and swallowing difficulties
- Functional dysphagia remains a grey zone—mechanisms and best treatments need more research.
Taylor & Francis Online - Translating rheological science into diet practices is promising but under-explored.
arXiv - More large trials are needed for neurostimulation, electrical stimulation, and novel sensor diagnostics.
- Integration of machine learning in clinical workflow is nascent but promising.
