Dysphagia (Swallowing Disorder): What It Is, Symptoms, Causes & Treatment
Request Call Back
Overview
Dysphagia means having trouble moving food or liquids safely from the mouth to the stomach. It can affect people of any age, but it is more common after stroke, in certain neurological diseases, and with structural problems of the throat or esophagus. Because dysphagia raises the risks of choking, aspiration pneumonia, malnutrition, and dehydration, timely assessment and treatment matter.
At MedicalPoint Hospital, our ear–nose–throat (ENT) specialists, gastroenterologists, neurologists, radiologists, dietitians and speech-language pathologists (SLPs) work together to diagnose the cause and design a personalized plan to help you swallow safely.
What is a swallowing disorder?
Dysphagia is difficulty swallowing solids, liquids, or both. The swallow is a highly coordinated action involving the mouth, pharynx (throat), larynx (voice box/airway) and esophagus. Problems can occur in one or more phases:
- Oral dysphagia: difficulty chewing, forming, or controlling the bolus in the mouth (e.g., weak tongue or facial muscles, poor dentition).
- Pharyngeal dysphagia: trouble initiating the swallow in the throat; food “goes the wrong way,” causing coughing or aspiration.
- Esophageal dysphagia: food sticks lower down after the swallow, often from narrowing, reflux injury or motility problems.
You may see these terms grouped as oropharyngeal (mouth/throat) vs esophageal (food pipe) dysphagia.
Common signs and symptoms
Symptoms vary with location and cause. Typical features include:
- A sensation that food is stuck in the throat or chest
- Coughing, choking, or throat clearing during meals; watery eyes or voice changes after swallowing
- Pain with swallowing (odynophagia) or heartburn/regurgitation
- Drooling, pocketing food in the cheeks, or taking much longer to finish meals
- Unintended weight loss, dehydration, or recurrent chest infections
- Voice hoarseness or a “wet”/gurgly voice after drinking
- Hiccups or repeated belching with meals
Red flags—seek care urgently: inability to swallow saliva, suspected aspiration, black or bloody stools, severe chest pain, or food impaction that does not pass.
Why does dysphagia happen? (Key causes)
- Neurologic disorders: stroke, Parkinson’s disease, multiple sclerosis, motor neuron disease, dementia, traumatic brain injury, peripheral neuropathies.
- Structural problems: esophageal strictures (scars from gastro-esophageal reflux disease, “GERD”), rings/webs, tumors, enlarged thyroid, Zenker diverticulum, tonsillar hypertrophy.
- Motility disorders: achalasia, diffuse esophageal spasm, hypercontractile (jackhammer) esophagus, scleroderma-related hypomotility.
- Inflammatory conditions: eosinophilic esophagitis, infectious esophagitis (in the immunocompromised), radiation injury.
- Iatrogenic/trauma: post-intubation or post-surgical changes, cervical spine surgery, head-and-neck radiotherapy.
- Aging and frailty: sarcopenia, reduced saliva, dental problems.
- Medication effects: anticholinergics (dry mouth), sedatives/opioids (reduced alertness), bisphosphonates or tetracyclines (pill esophagitis).
How is dysphagia diagnosed?
Evaluation aims to localize the problem, find the cause, and prevent aspiration. Your clinician may recommend:
- Clinical swallowing assessment by an SLP
- Review of medical history, cranial nerve exam, observation of test sips/bites, postural and breathing coordination.
- Instrumented swallowing studies
- Videofluoroscopic Swallow Study (VFSS / modified barium swallow): a moving X-ray that shows bolus flow and airway protection for different textures.
- Fiberoptic Endoscopic Evaluation of Swallowing (FEES): a slim scope through the nose to view the pharynx and larynx during swallowing; helpful at bedside and for secretion management.
- Esophageal testing (especially if food sticks lower in the chest)
- Barium esophagram to detect rings, webs, strictures or motility patterns.
- Upper endoscopy (EGD): direct visualization, biopsy (e.g., eosinophilic esophagitis), and dilation if safe.
- High-resolution esophageal manometry: gold standard for diagnosing achalasia and other motility disorders.
- pH or pH-impedance monitoring when reflux is suspected.
- Additional tests as indicated
- Labs for nutrition/hydration, chest imaging for aspiration, neurology evaluation and brain imaging after stroke.
At MedicalPoint Hospital, these services are coordinated so that most patients receive same-week imaging and SLP assessment, speeding diagnosis and care.
Treatment: personalized, stepwise, and cause-directed
Most people improve with a combination of rehabilitation, dietary strategies, and medical/surgical care tailored to the underlying cause.
1) Swallowing rehabilitation (Speech-Language Pathology)
- Compensatory strategies: chin-tuck, head turn/tilt, effortful swallow, supraglottic swallow, double swallow, pacing and small sips.
- Texture modifications using IDDSI (International Dysphagia Diet Standardisation Initiative) levels—ranging from thin liquids to purees or soft/regular solids—to match safety and efficiency.
- Targeted exercises to strengthen tongue, lips, pharyngeal constrictors and suprahyoid muscles; respiratory-swallow coordination and airway protection training.
- Environmental & behavioral changes: upright posture, unhurried meals, alternating solids and liquids, meticulous oral hygiene to cut aspiration pneumonia risk.
2) Nutrition support
- Dietitian-guided plans to maintain calories, protein, and hydration.
- Thickening agents for liquids when aspiration risk is high.
- Temporary or long-term feeding tubes (e.g., NG or PEG) may be considered if oral intake is unsafe or insufficient—always reassessed as therapy progresses.
3) Medical therapy
- GERD management: proton-pump inhibitors (PPIs), lifestyle measures (weight management, head-of-bed elevation, meal timing).
- Eosinophilic esophagitis: elimination diets, topical swallowed steroids under GI guidance.
- Salivary and secretion management: optimizing hydration; medication review to reduce xerostomia; airway protection strategies.
4) Endoscopic and surgical options (for selected causes)
- Endoscopic dilation for benign strictures or Schatzki rings.
- Achalasia: pneumatic dilation, Heller myotomy with fundoplication, or per-oral endoscopic myotomy (POEM)—chosen based on manometry subtype and patient factors.
- Cricopharyngeal dysfunction/Zenker diverticulum: endoscopic or open myotomy/diverticulotomy in collaboration with ENT.
- Head & neck cancer–related dysphagia: tumor-directed therapy plus proactive swallowing rehab to preserve function.
Care is individualized; the goal is safe, efficient swallowing and quality of life.
Practical safety tips at home
- Sit fully upright (≥90°) for meals and remain up for 30–45 minutes after.
- Take small bites and sips; avoid talking while chewing; focus on one swallow at a time.
- Alternate solid–liquid–solid to clear residue.
- Follow the texture and thickness level recommended by your SLP.
- Maintain daily oral care (toothbrushing, denture cleaning).
- If coughing or “wet voice” occurs with a new texture, stop and reassess; contact your care team.
When should I see a doctor?
- Ongoing choking, coughing or recurrent chest infections
- Unintentional weight loss, dehydration, or fear of eating
- Food impaction or sudden inability to swallow
- Painful swallowing, blood in stools/vomit, or new progressive dysphagia
Early evaluation prevents complications and often makes treatment simpler.
