Dysphagia, Aspiration & Foreign Bodies
Assess swallowing safety and recognise complete obstruction or dangerous ingested objects.
Quick revision ↓ Medical Dictionary
01Localise swallowing difficulty
Distinguish difficulty initiating a swallow from food sticking after swallowing. Ask about solids, liquids, progression, pain, regurgitation, cough and weight loss. Oropharyngeal dysfunction can cause aspiration, while oesophageal symptoms may need gastrointestinal investigation. The patient’s perceived sticking level is helpful but not always an exact anatomical localisation.
02Immediate danger
Inability to swallow saliva, drooling, respiratory distress or suspected complete food-bolus obstruction needs emergency assessment. A patient with a threatened airway requires the airway pathway first. Do not encourage repeated eating or drinking to push an obstruction down. Keep oral intake decisions aligned with the treating team while urgent evaluation is arranged.
03Aspiration assessment
Coughing during meals, a wet voice, recurrent chest infections or neurological disease can suggest unsafe swallowing, but aspiration may also be silent. Speech and language or swallowing specialists guide assessment and dietary recommendations. Texture changes and feeding strategies should be individualised rather than imposed without evaluation. Consider hydration, nutrition and medicine administration alongside airway protection.
04Sharp objects and batteries
A swallowed button battery, sharp object or concerning foreign body requires urgent specialist advice and appropriate imaging or endoscopic pathways. Button batteries can cause rapid tissue injury, especially in the oesophagus. Do not induce vomiting or rely on absence of pain. Advice about interim measures must follow the current poison or emergency service protocol and must not delay removal assessment.
05Persistent symptoms
Progressive dysphagia, weight loss, bleeding or unexplained persistent pain warrants urgent investigation for structural disease, including malignancy. Normal mouth inspection does not exclude oesophageal or hypopharyngeal pathology. Ensure referral and nutrition support are coordinated. A reassuring initial test does not end the assessment when symptoms remain unexplained or continue to progress.
High-Yield Revision
- Inability to handle saliva suggests a serious obstruction.
- Aspiration can occur without coughing.
- Button batteries and sharp objects require urgent specialist pathways.
Common Pitfalls
- Trying to push a food bolus down with more food.
- Assuming normal mouth findings exclude deeper disease.
