vitamin deficiency
Let an agent explain vitamin deficiencies in general terms, relay symptoms, causes and public health measures from clinical and public health sources, distinguish dietary from inherited and malabsorptive forms, 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 vitamin deficiencies in general terms, relay symptoms, causes and public health measures from clinical and public health sources, distinguish dietary from inherited and malabsorptive forms, and route personal questions to clinicians.
A nutritional disorder caused by insufficient intake, absorption or metabolism of one or more vitamins, producing conditions such as scurvy from vitamin C deficiency, rickets and osteomalacia from vitamin D, beriberi from thiamine, pellagra from niacin, pernicious anaemia from vitamin B12 and night blindness from vitamin A; deficiencies arise from poor diet, malabsorption, increased needs, inherited metabolic disorders and some medicines, and are diagnosed and treated clinically.
What it is for: Not applicable; a category of disease.
It can be explain kinds and causes in general terms; relay recognised signs and risk groups; relay public health measures such as fortification; route personal diagnosis and supplementation to clinicians.
Distinguishing features
Specific to each vitamin
Dietary, malabsorptive or inherited causes
Often reversible with treatment
Public health prevention by fortification
What it looks like
Not a visible object; presentations range from fatigue and skin changes to bone deformity and neurological signs.
How it is recognised
Disease from lack of a specific vitamin
Named syndromes per vitamin
Mineral deficiencies and protein-energy malnutrition are separate categories

What the second pass must settle
- Should each named deficiency disease be a separate entry?
- How should reference intakes be linked by country?
- The registry entry has merged aliases for rare inherited disorders and animal deficiencies; should they be split off?
