The HealthDiseases Research Team writes the site's condition guides, symptom explainers, medical test pages and health guides.
Methodology
Each article begins with the primary sources: government health agencies (NIH institutes such as NIDDK, NINDS and the Office of Dietary Supplements; CDC; FDA; MedlinePlus; and their UK, Canadian and Australian equivalents), clinical practice guidelines from major professional bodies, and systematic reviews and landmark trials indexed in PubMed. Sources are read in full and registered centrally so the same study is cited consistently across the site. Claims that cannot be traced to a source of this kind are not published.
Articles follow a consistent structure — what the condition is, what changes in the body, causes, symptoms, diagnosis, complications, treatment, everyday management, when to seek care — and are written for a general adult reader at roughly a grade 7–9 reading level, with technical terms explained.
Sources used
The reference list at the foot of every article shows exactly which sources support it. PubMed identifiers are included only when the article has been located and read; institutional pages are cited by URL and re-checked periodically.
What "fact checked" means
Before publication, every article is read against its sources by the Health Content Editor, who removes anything unsupported, checks numbers and thresholds, and confirms that language does not overstate evidence.
What this role does not claim
No one writing under this role is a licensed physician, pharmacist, dietitian or nurse, and no article carries a "medically reviewed" label unless a named, verifiable clinician has personally reviewed it — see the medical review policy. Bylines identify the editorial role responsible, not an individual, so that readers are not given a false impression of clinical authority.
