dysphagia
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
