Approach to swallowing problems (oropharyngeal dysphagia)
- Approach to a complaint
Oropharyngeal dysphagia is difficulty starting a swallow; it shows as coughing or choking when eating and usually has a neurological cause.

What it is
Dysphagia is the feeling that food or liquid does not pass well or gets stuck. Oropharyngeal (transfer) dysphagia affects the start of the swallow: the patient coughs, chokes, has a wet voice or regurgitates through the nose. Oesophageal dysphagia feels like a bolus stopping behind the breastbone. Telling them apart guides the workup: oropharyngeal dysphagia is assessed by a speech-language therapist with videofluoroscopy or endoscopic evaluation of swallowing; oesophageal dysphagia with upper endoscopy and a barium swallow. The main risks are aspiration pneumonia, malnutrition and dehydration.
Key questions in the history
- Is it hard to start the swallow, or does food feel stuck in the chest?
- Coughing or choking when eating or drinking? Liquid coming out of the nose?
- Solids only, or liquids too from the start?
- Is it progressive? Any weight loss?
- Weakness, tremor, nasal voice, drooping eyelids or fatigue that worsens during a meal?
- Regurgitation of undigested food hours later, or bad breath?
- Previous neck radiotherapy or drugs that dry the mouth?
Causes and classification
- Neurological: stroke, Parkinson disease, multiple sclerosis, ALS and spinal cord injury.
- Neuromuscular: myasthenia gravis and myopathies.
- Structural, pharynx and upper oesophagus: Zenker diverticulum, head and neck cancer, webs (Plummer-Vinson) and after-effects of surgery or radiotherapy.
- Oesophageal (differential): stricture, oesophageal cancer, achalasia, oesophageal spasm, eosinophilic oesophagitis and reflux.
- Dry mouth: drugs, Sjögren disease or radiotherapy.
- Functional: globus causes a feeling of a lump but no real difficulty swallowing.
Step-by-step approach
- Confirm it is dysphagia (real difficulty swallowing) and not globus (a lump feeling with no trouble eating).
- Localise it: oropharyngeal (starting the swallow, coughing, nasal regurgitation) or oesophageal (bolus stuck in the chest).
- Pin down food type and course: solids only and progressive suggests obstruction; liquids from the start suggests a motor disorder.
- Look for signs of aspiration: coughing with meals, wet voice, repeated pneumonia.
- Do a neurological and cranial nerve exam, and examine the mouth, pharynx and neck.
- Assess nutrition and hydration: current weight, recent loss and intake.
- Request a swallowing study: speech-language assessment, videofluoroscopy or FEES.
- If an oesophageal cause or a red flag is suspected, request upper endoscopy or a barium swallow.
Differential diagnosis of dysphagia
| Cause | Clues | First test |
|---|---|---|
| Neurogenic dysphagia (stroke, Parkinson, ALS) | Coughing on swallowing, wet voice, neurological deficit | Swallow screen and videofluoroscopy or FEES |
| Myasthenia gravis | Worse as the meal goes on, ptosis, nasal voice | Neurological exam and myasthenia workup |
| Zenker diverticulum | Older adult, regurgitation of undigested food, bad breath | Barium swallow |
| Oesophageal or head and neck cancer | Progressive dysphagia, weight loss, tobacco and alcohol | Endoscopy and biopsy |
| Achalasia | Solids and liquids, regurgitation | Barium swallow and manometry |
| Eosinophilic oesophagitis | Young adult, food sticking, atopy | Endoscopy with biopsies |
Red flags
- Unexplained weight loss.
- Progressive dysphagia for solids.
- Aspiration pneumonia or coughing with every meal.
- Vomiting blood or coffee-ground material, or black stools.
- Associated neck lump, hoarseness or earache.
- Unable to swallow own saliva or food stuck: an emergency.
- Sudden onset with a neurological deficit: possible stroke.
Next step / Initial management
- First test: swallowing assessment by a speech-language therapist, with videofluoroscopy or FEES as available; upper endoscopy if the cause looks oesophageal or there is a red flag.
- First measures: change food texture, thicken liquids, eat sitting upright and use swallowing techniques.
- Treat the cause: reflux with acid-reducing drugs; strictures with endoscopic dilation; a feeding tube if the patient cannot eat enough or keeps aspirating.
- Refer urgently, the same day, for food stuck, inability to swallow saliva or dysphagia with an acute neurological deficit.
- Priority referral (within days) to gastroenterology or ENT for weight loss, progressive dysphagia or a neck lump; routine referral to speech-language therapy for stable chronic dysphagia.
Test yourself
Think of the answer, then tap the question to see it.
A 70-year-old woman has coughed and choked on liquids since a stroke a month ago. What type of dysphagia is it and which test do you request?
Neurogenic oropharyngeal dysphagia. Speech-language assessment with videofluoroscopy or FEES to look for aspiration and adjust the diet.
A 75-year-old man regurgitates undigested food hours after eating and has bad breath. Likely diagnosis and test?
Zenker diverticulum; barium swallow. Endoscopy must be done with care because it can perforate the diverticulum.
What does progressive dysphagia for solids only, with weight loss, suggest in a smoker?
Mechanical obstruction, above all oesophageal or head and neck cancer; it needs priority endoscopy with biopsy.
How is dysphagia told apart from globus?
In globus there is a lump feeling in the throat with no real difficulty swallowing food; in dysphagia the bolus does not pass well.
