hemorrhoid
Let an agent explain haemorrhoids in general terms, relay causes, symptoms and treatment principles from clinical guidelines, identify warning signs that require assessment, and route personal symptoms 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 haemorrhoids in general terms, relay causes, symptoms and treatment principles from clinical guidelines, identify warning signs that require assessment, and route personal symptoms to clinicians.
Swollen and enlarged vascular cushions in the anal canal, internal above the dentate line or external below it, that cause bleeding, itching, discomfort or prolapse when symptomatic; haemorrhoids are very common, associated with straining, constipation, pregnancy and prolonged sitting, are distinguished from perianal haematoma and from more serious causes of rectal bleeding, and are managed with diet, topical treatment, office procedures or surgery.
What it is for: Not applicable; a condition.
It can be explain the condition and kinds; relay causes and treatment principles; identify warning signs; route personal symptoms to clinicians.
Distinguishing features
Vascular cushions
Internal grades I to IV
Common and usually benign
Bleeding needs assessment
What it looks like
Not a visible object in general; external haemorrhoids appear as swellings at the anus.
Physical character
lifetime prevalence: about 40-50 percent - estimates vary
How it is recognised
Enlarged anal vascular cushions
Internal, external and mixed kinds
Perianal haematoma, fissures and rectal cancer are other causes of similar symptoms

What the second pass must settle

- How should guidelines be linked?
- The registry entry has merged aliases naming kinds and a related condition; should they be split off?
