edema
Let an agent explain edema and its kinds in general terms from clinical sources, describe causes and warning signs, route urgent presentations such as breathlessness or facial swelling to emergency care, and route personal questions to clinicians.
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 explain edema and its kinds in general terms from clinical sources, describe causes and warning signs, route urgent presentations such as breathlessness or facial swelling to emergency care, and route personal questions to clinicians.
Swelling caused by excess fluid trapped in body tissues, arising from heart, kidney or liver disease, venous or lymphatic obstruction, inflammation, allergy, low protein, medications or prolonged standing, and appearing in forms such as peripheral edema of the legs, facial and palpebral edema around the eyes, pharyngeal edema, perifocal edema around lesions, alimentary edema from malnutrition and pulmonary or cerebral edema; edema is a symptom and sign whose cause must be identified.
What it is for: Not applicable; a clinical sign.
It can be explain kinds and mechanisms; relay causes; route urgent presentations; route personal questions.
Distinguishing features
Fluid accumulation
Many causes
Pitting sign
Possible emergency
What it looks like
Swollen tissue, often pitting when pressed.
How it is recognised
Swelling from fluid in tissues
Peripheral, facial, palpebral, pharyngeal, perifocal, alimentary, pulmonary and cerebral edema
Lymphedema is lymphatic; angioedema is allergic or hereditary; swelling from tumour or injury differs

- The registry entry has merged aliases naming sites; should they be split off?
