The Peri Signals editors
The Peri Signals editors keep the site's pages current: they check every health fact against the source it links, update pages when guidance changes, and correct errors readers report.
Our writers work from health guidance a reader can open: the NHS, ACOG, NICE, MedlinePlus and published studies, each linked where it is used. They do not give treatment advice. The full rules are in the editorial policy, and you can send a correction at any time.
