The British and international English spelling of amenorrhea; the absence of menstrual periods.
This is the alternate British spelling using '-rrhoea' (from Greek 'rhoia,' flow) instead of the American '-rrhea,' reflecting historical spelling conventions across English-speaking regions.
British medical spelling preserves the double-'r' from Greek more faithfully than American spelling—compare 'diarrhoea' (British) to 'diarrhea' (American), a spelling split dating to the 1800s.
British spelling variant of amenorrhea; same etymology and medical pathologizing history rooted in male-dominated medical establishment.
Use clinically with attention to patient experience; distinguish between physiological variation and pathology requiring intervention.
