Synopsis
Localise swallowing difficulty to oropharyngeal or oesophageal phases, recognise aspiration, food-bolus obstruction and cancer risk, and sequence endoscopy, swallow imaging and manometry safely.
- Ask where initiation fails rather than where food feels stuck: coughing, nasal regurgitation, wet voice and repeated swallows suggest oropharyngeal dysfunction even when the patient points to the neck.
- Oesophageal dysphagia to solids first suggests mechanical narrowing, while difficulty with both solids and liquids from onset supports motility disease; neither rule is absolute.
- Progressive dysphagia, weight loss, iron-deficiency anaemia or older-age new onset needs the current urgent oesophageal cancer pathway and prompt endoscopy.
- Intermittent food impaction in a younger person raises eosinophilic oesophagitis or a ring; normal-looking mucosa does not remove the need for appropriate oesophageal biopsies.
- Odynophagia points towards mucosal injury from reflux, tablets, infection, radiation or malignancy and is distinct from mechanical transit difficulty, although both can coexist.
- After acute stroke, screen swallowing before any food, drink or oral medicine, and obtain specialist swallowing assessment when the screen is abnormal.
- Upper gastrointestinal endoscopy assesses mucosa and narrowing, barium studies define selected structural or pharyngeal problems, and high-resolution manometry characterises motility after mechanical disease is excluded.
- Do not arrange blind dilatation of unexplained dysphagia. Define anatomy, obtain biopsies when required, consent for perforation risk and use an experienced endoscopy pathway.
- Nutrition, hydration, aspiration and medication formulation need active management while diagnosis proceeds; simply telling a patient to eat soft food is not a complete safety plan.
Key red flags
Delayed initiation, coughing during swallowing, nasal regurgitation, wet voice, repeated swallows, drooling or neurological signs localise towards oral or pharyngeal dysfunction and carry immediate aspiration and nutrition risk.
Sudden inability to swallow liquids or saliva with drooling after eating indicates complete obstruction. Airway symptoms, sharp-bone ingestion or perforation signs increase urgency and require coordinated emergency endoscopy.
Investigation priorities
Determine whether oral intake and medicines are safe immediately after acute stroke or neurological deterioration.
Management branches
The patient cannot swallow saliva or has respiratory compromise after eating.
- Assess airway, breathing and haemodynamics, keep the patient nil by mouth, remove loose oral material only when safely visible and call senior endoscopy and anaesthetic support.
- Establish time and food or foreign-body type, anticoagulants, prior impactions and perforation features; avoid forceful oral intake or blind instrumentation.
- Arrange emergency therapeutic endoscopy on the locally defined timeline, with surgical input for sharp objects, perforation, failed removal or other complication.
- After clearance, investigate the underlying cause with biopsies and follow-up rather than treating food bolus as an isolated accident.
