dehydration
Let an agent explain dehydration in general terms, relay causes, types, signs, prevention and oral rehydration from WHO and clinical sources, route severe dehydration to urgent care, describe the named forms and historical terms, and distinguish dehydration from hypovolaemia, heat stroke, overhydration and dehydration in chemistry.
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 dehydration in general terms, relay causes, types, signs, prevention and oral rehydration from WHO and clinical sources, route severe dehydration to urgent care, describe the named forms and historical terms, and distinguish dehydration from hypovolaemia, heat stroke, overhydration and dehydration in chemistry.
A deficit of total body water, with or without sodium imbalance, caused by losses from sweating, vomiting, diarrhoea, fever, burns or diuretics, or by inadequate intake, classified as isotonic, hypertonic with raised sodium or hypotonic with low sodium dehydration; exsiccosis is an older term, and infant toxicosis is a historical term for severe dehydration with toxic symptoms in infants with diarrhoea. Signs include thirst, dry mouth, dark urine, dizziness and, in severe cases, confusion, rapid heartbeat and low blood pressure; oral rehydration solution, a WHO-recommended treatment, has saved millions of lives. Infants, older adults and people with severe diarrhoea are at higher risk, and signs of severe dehydration need urgent medical care.
What it is for: Not applicable; a body fluid deficit.
It can be explain causes and types; relay signs and oral rehydration; describe named forms; route severe dehydration.
Distinguishing features
Water deficit
Sodium-based types
High-risk groups
Treatable with ORS
What it looks like
Dry lips, sunken eyes, reduced tears and dark urine; in infants a sunken soft spot.
Physical character
WHO low-osmolarity ORS: 2002 year - formula update
ORS described as major medical advance: 1978 note - The Lancet editorial, attributed
severe dehydration fluid loss: more than about 10 percent of body weight in children note - clinical scales vary
How it is recognised
Deficit of body water
Sweating-related dehydration, hypotonic dehydration, hypertonic dehydration, isotonic dehydration, exsiccosis, infant toxicosis
Hypovolaemia is low blood volume; heat stroke is overheating; overhydration is excess water; chemical dehydration removes water from compounds
