vr.tr.dysphagia · INF.KNW

Let an agent route choking, total inability to swallow and food bolus obstruction to emergency care, explain dysphagia types, causes, assessment and management in general terms from gastroenterology and speech and language therapy sources, describe the named forms, and distinguish dysphagia from odynophagia, globus sensation and eating disorders, without diagnosing individuals.

Research draft, second pass

A second pass drafted this model: the structure a model of this thing needs, and what is known about it in the world. The line under this one says how the second half was obtained - researched against sources, or recalled without web access, in which case nothing here was read anywhere and every claim is a lead to verify. Unreviewed either way.

Purpose and description

Let an agent route choking, total inability to swallow and food bolus obstruction to emergency care, explain dysphagia types, causes, assessment and management in general terms from gastroenterology and speech and language therapy sources, describe the named forms, and distinguish dysphagia from odynophagia, globus sensation and eating disorders, without diagnosing individuals.

Difficulty in swallowing food, liquids or saliva, a symptom rather than a disease, divided into oropharyngeal dysphagia, often from stroke, Parkinson s disease or other neurological conditions, and oesophageal dysphagia from structural or motility problems such as oesophageal motility disorders like achalasia, strictures, tumours, eosinophilic oesophagitis, food bolus obstruction and, rarely, dysphagia lusoria from compression by an aberrant subclavian artery; dysphagia can cause choking, aspiration pneumonia and malnutrition. Food stuck with inability to swallow saliva, or choking, needs emergency care, and new or worsening swallowing difficulty should be assessed promptly.

What it is for: Not applicable; a symptom.

It can be route emergencies first; explain types and causes in general terms; describe named forms; relay assessment and texture guidance.

Distinguishing features

Symptom not disease

Oropharyngeal or oesophageal

Aspiration risk

Warning sign for cancer in some cases

What it looks like

Coughing, choking or effort when swallowing; food sticking sensation.

Physical character

texture framework: IDDSI levels 0-7 note - International Dysphagia Diet Standardisation Initiative

key tests: endoscopy, barium swallow, videofluoroscopy, manometry list

major complication: aspiration pneumonia note

How it is recognised

Difficulty swallowing

Inability to swallow, oesophageal dysphagia, oropharyngeal dysphagia, dysphagia lusoria, oesophageal motility disorder, food bolus obstruction

Odynophagia is painful swallowing; globus is a lump sensation without obstruction; eating disorders are psychiatric

  • How should IDDSI be linked?
  • How should red flag guidance be kept current?
