Dysphagia: Recognizing Swallowing Disorders

Swallow It seems simple, but it's a complex coordination which involves more than 30 muscles. When it becomes disrupted, we refer to it as dysphagia. The problem is underdiagnosed : People with dysphagia often adapt—by eating more slowly or avoiding certain textures—without realizing that an evaluation could change their daily lives [1]. This article explains what dysphagia is, the signs to look for, the most common causes, assessment by a speech-language pathologist, and resources available in Quebec.

What Is Dysphagia?

Visit dysphagia means any difficulty swallowing. It can be located in the mouth, in the pharynx or in the’esophagus. The consequences range from discomfort to serious complications [1][2].

The Three Main Phases of Swallowing

• Oral phase : preparation of food in the mouth (chewing, salivation, formation of a cohesive mouthful)
• Pharyngeal phase : rapid movement of the bolus into the throat, accompanied by protective closure of the airways (elevation of the larynx, closure of the epiglottis)
• Esophageal phase : movement of the contents of the stomach down the esophagus through peristaltic contractions
• A derailment at any stage can cause dysphagia
• Visit oropharyngeal dysphagia is most common among older adults and neurological patients
• Visit esophageal dysphagia suggests, rather, an obstruction (stenosis, tumor, ring) or a motor disorder (achalasia, spasm)

Why It's Important

• The consequences range from’discomfort serious complications
• Aspiration Pneumonia (inhalation of food or saliva into the lungs)
• Malnutrition and dehydration by reducing intake
• Social isolation, discomfort with eating in public
• Weight loss unintentional
• Deterioration quality of life and mood
• Increased risk of chutes, hospitalizations, and placement in residential care
• A early intervention can prevent most of these complications

Key Takeaways

• Visit dysphagia is underdiagnosed, especially among older adults and people living with a neurological disorder [1]
• Visit signs may be subtle: coughing during meals, a hoarse voice, meals that drag on, avoiding certain foods
• Visit causes include: stroke, neurodegenerative diseases, ENT cancers, severe reflux, and aging
• L’evaluation is performed by a specialized speech-language pathologist, sometimes supplemented by videofluoroscopy or fiberoptic endoscopy of swallowing [2]
• Visit support combines dietary changes, exercise, treatment of the underlying cause, and nutritional support
• A evaluation Early intervention improves quality of life and prevents serious complications
• In Quebec, the’speech-language pathologist The OOAQ is the key professional for the assessment and rehabilitation of swallowing [3]

Signs to Look For

Visit signs are sometimes obvious, but often insidious. Special caution is warranted in the elderly, patients with neurological conditions, or those with a history of head and neck cancer.

During and after meals

• Cough or a scraping sound during or after meals
• Sensation that food «doesn't go down right» or «gets stuck»
• A hoarse voice or hoarse after drinking or eating
• Sensation a lump at the base of the neck or behind the sternum
• Regurgitation nasal regurgitation (fluid or food coming back up through the nose)
• Watery Eyes or facial flushing when swallowing
• Feeling of’choking in short, followed by a cough

• Drool or food particles in the mouth
• Weight loss unintentional
• Avoidance certain foods (meat, dry bread, rice, tablet-form medications)
• Chew every bite lasts much longer than before
• Prefer soft foods, purees, and foods with a high moisture content
• Drink take small sips or avoid clear liquids
• Social withdrawal when eating with family or in a group

More serious symptoms

• Recurrent Pneumonia, often unexplained
• Fever or an unusual cough the day after a meal
• Choking with food stuck in the throat (emergency: Heimlich maneuver, 911)
• Vomiting after-meal episodes
• Dehydration or weakness, especially among older adults
• Confusion acute, which may be the only sign of aspiration pneumonia

When to Seek Medical Attention Immediately

• Dysphagia caused by’rapid onset
• Weight loss recent and unexplained
• Difficulty marked to swallow solids
• Regurgitation frequent or regurgitation of undigested food
• Pain during swallowing (odynophagia)
• Pneumonia unexplained and repeated
• Dysphagia in a patient with a history of ENT cancer, cervical radiation therapy, or a recent stroke

The Most Common Causes

Visit causes There are many. The medical evaluation aims to identify them, because treatment depends on the underlying cause [1].

Neurological causes

• AVC — the leading cause in adults (up to 50 % of patients experience dysphagia during the acute phase)
• Neurodegenerative Diseases : Parkinson's disease, ALS, multiple sclerosis, dementias (Alzheimer's, frontotemporal)
• Trauma skull tumors, brain tumors
• Violations cranial nerves
• Encephalitis and other inflammatory conditions

Structural and oncological causes

• ENT Cancers (head and neck) and their treatments (cervical radiation therapy, surgery)
• Cancers of the esophagus
• Stenoses peptic (reflux-related), caustic, and post-surgical esophageal lesions
• Rings and esophageal membranes
• Diverticula (notably by Zenker)
• Gastroesophageal reflux disease severe esophagitis
• Goiter compressive
• Postintubation or post-ENT/esophageal surgery

Muscular and systemic causes

• Muscle disorders : myasthenia gravis, muscular dystrophies, polymyositis, dermatomyositis
• Achalasia (esophageal motility disorder)
• Scleroderma and other systemic diseases
• Aging and sarcopenia (presbyphagia)
• Effects unwanted certain medications (dry mouth, sedation, decreased pharyngeal tone)
• Deficiencies important nutritional benefits

Psychiatric and functional causes

• Anxiety Major disorders and phobias related to swallowing (phagophobia)
• Sensation a lump in the throat («globus pharyngeus»), which is usually benign but uncomfortable
• Trouble eating disorders (anorexia, oral disorders in young people)
• The Causes functional still require an evaluation to rule out an organic cause

The Evaluation

The assessment is structured and combine often includes a clinical component and specialized tests. In Quebec, the’speech-language pathologist is the key professional for swallowing [3].

Clinical Evaluation by a Speech-Language Pathologist

• Medical History detailed (medical history, medications, progression of symptoms)
• Review of the mouth, the lips, the tongue, and the soft palate
• Evaluation oral and pharyngeal sensitivity
• Water Test, testing various textures (pureed, solid) under observation
• Observation voice changes before and after swallowing
• Measure on meal duration and eating behavior
• Identification of aggravating factors and strategies that have already been used
• Map Initial phase of rehabilitation and recovery

Specialized Exams

• Videofluoroscopic Study of Swallowing («cookie swallow» or VFSS): radiological recording of swallowing using a contrast agent, performed in a specialized department
• Fibroscopy of Swallowing (FEES): a flexible camera inserted through the nose to view the pharynx and larynx while the person swallows
• Manometry esophageal dysfunction in certain motor disorders
• Endoscopy gastrointestinal (esophagogastroduodenoscopy) to check for strictures, tumors, or esophagitis
• Imaging brain imaging (CT, MRI) depending on the neurological context
• Financial Statements blood tests to screen for deficiencies, infections, and metabolic disorders

Comprehensive Medical Evaluation

• Identification of the underlying cause
• Search associated neurological signs
• Evaluation Nutritional (weight, nutritional status, food intake)
• Search signs of aspiration (chronic cough, recurrent respiratory infections)
• Review of the medications that may worsen dysphagia
• Orientation to the appropriate specialists (neurologist, ENT specialist, gastroenterologist)
• Coordination with the interdisciplinary teams (speech-language pathologist, dietitian, occupational therapist)

Coverage

Visit support is multidisciplinary and personalized. It aims to ensure food security, maintain good nutritional status, and recover the function as much as possible.

Dietary Adjustments

• Modification textures: soft, chopped, mashed, or pureed foods, depending on the degree
• Thickeners for liquids (water, juice, coffee), as recommended
• Postures and swallowing techniques learned with the speech-language pathologist (chin down, forced swallowing)
• Small bites, slow pace, no distractions
• Hydration regularly throughout the day, in small amounts
• Avoid high-risk foods (large pieces, skins, tough fibers, mixtures of solids and liquids), depending on the situation
• Adapter utensils (appropriate glasses, small spoons) as needed

Rehabilitation Exercises

• Exercises targeted based on the affected structure (tongue, soft palate, larynx)
• Maneuvers specific (Mendelsohn, Shaker, stress swallowing)
• Stimulation sensory (temperatures, flavors)
• Work on breathing and the coordination of breathing and swallowing
• Progress assessed regularly by the speech-language pathologist
• Visit exercises must be tailored to the condition (post-stroke, Parkinson's, post-radiation, etc.)

Medical and Surgical Treatment

• Treatment the underlying cause (reflux, infection, neurological disorder)
• Dilation endoscopic treatment for stenosis
• Surgery in certain cases (Zenker's diverticulum, achalasia, tumors)
• Injection botulinum toxin in certain cases of achalasia
• Optimization existing medications (reducing sedatives, treating reflux, treating Parkinson's disease)
• In cases where severe, temporary or long-term use of enteral feeding (nasogastric tube, gastrostomy) based on the patient's test results and preferences

Nutritional Support from a Dietitian

• Evaluation intake and nutritional status
• Adaptation recipes featuring recommended textures without sacrificing the enjoyment of eating
• Supplements nutritional, if necessary
• Tracking body weight and biological parameters (albumin, vitamins, electrolytes)
• Advice for family caregivers on meal preparation

Medication Adjustments

• Liquid Forms or may be crushed, after consulting a pharmacist (some tablets should never be crushed)

Special Case: Dysphagia in Older Adults

Visit dysphagia is frequent among older adults, but often mistaken for a «normal» sign of aging. It is a common misconception to be corrected.

What Changes as We Age

• Decline muscle tone (presbyphagia)
• Decrease decreased saliva production (xerostomia)
• Aging the sensory nerves of the mouth and pharynx
• Diseases Related articles (stroke, Parkinson's disease, dementia)
• Several medications high-risk (sedatives, antipsychotics, anticholinergics)
• The risk of complications is higher (pneumonia, malnutrition, dehydration)
• The table can be silent, as reported by family members or caregivers

Specific Consequences for Older Adults

• Aspiration Pneumonia, which is sometimes a major cause of morbidity and mortality
• Weight loss, sarcopenia, fragility
• Dehydration, urinary tract infections, falls
• Confusion acute and accelerated cognitive decline
• Isolation during meals, loss of enjoyment of food
• Risk of’hospitalization or placement in a residential facility
• A speech-language assessment and a tailored care plan can change the course of the disease

Good Habits for Everyday Life

• Encourage to consult a professional (doctor, speech-language pathologist) rather than simply «adapting»
• Serve meals in a quiet environment, free from distractions
• Install The person is sitting with their back straight and their chin slightly lowered.
• Serve modest portions, at a slow pace
• Check before the person swallowed the next bite
• Avoid to rush, distract, or scold

Myths and Misconceptions

«Having trouble swallowing is normal as you get older.»

False. Aging affects swallowing, but a true difficulty Any change that affects daily life is not «normal.» It warrants evaluation, if only to rule out a treatable cause and improve quality of life.

«If I cough, at least it doesn't go down into my lungs.»

Partially false. Coughing is a protective reflex, but it nevertheless Suctioning is not always silent, especially in older adults and patients with neurological conditions, who may inhale microparticles without coughing. That is why a speech-language evaluation is essential.

«Eating more slowly is enough»

Often insufficient. Eating more slowly can help, but it's not a systematic solution. Without an assessment, the aspiration risks, malnutrition, and pneumonia remain common. A professional approach is safer.

«A speech-language pathologist is just for speech»

False. The speech-language pathologist also evaluates and treats swallowing disorders, whether related to a stroke, a neurological disorder, an ENT cancer, or aging. Swallowing is an integral part of the scope of practice for speech-language pathologists in Quebec, as regulated by the OOAQ.

«There's nothing we can do about dysphagia.»

False. Many patients make a partial or full recovery after speech-language therapy, treatment of the underlying cause, and dietary adjustments. Even when a cure is not possible, a good care significantly improves quality of life and prevents complications.

Frequently asked questions

When should you seek medical attention for difficulty swallowing?

As soon as the difficulty is persistent, whether it lasts longer than a few weeks or affects diet, weight, breathing, or quality of life. Rapid onset, unexplained weight loss, pain when swallowing, or recurrent pneumonia require prompt medical attention.

Do you need a referral to see a speech-language pathologist in Quebec?

Direct access is available at private clinics, but a Medical prescription sometimes makes it easier to get reimbursed by insurance companies. In the public health care system, access is usually through a family doctor, the IPS, the CLSC, or a hospital. Wait times vary by region.

Are thickeners necessary in the long run?

Not always. Thickeners are a security measure, prescribed following an evaluation. Depending on the patient’s progress, they may be reduced or discontinued. The decision is made by the speech-language pathologist and the physician, sometimes based on a new videofluoroscopic or fibroscopic evaluation.

Is it possible to regain normal swallowing after a stroke?

Often, yes, especially in the first few months. The speech therapy is more effective if it begins early. Recovery depends on the severity of the stroke, the affected area, age, and comorbidities. Many patients are able to resume a normal or nearly normal diet.

What foods should you avoid if you have dysphagia?

It depends on the type and severity of dysphagia. In general, the high-risk foods These include hard or sticky foods, long fibers, stringy pasta, nuts, mixtures of solids and liquids (such as soup with chunks), and large pieces of dry meat. The speech-language pathologist tailors the list to the individual.

Is a gastrostomy required in severe cases?

No. It's a option Considered in severe or prolonged cases, depending on the patient’s condition, goals, and prognosis. The decision is made jointly by the patient, their family, the doctor, the speech-language pathologist, and the dietitian. It may be temporary or permanent.
