polymenorrhoea
Pronunciation: pol-ee-men-oh-REE-ah
Frequent menstrual periods occurring at intervals less than 21 days.
Full Definition
Polymenorrhoea describes abnormally frequent menstrual cycles with intervals shorter than 21 days between periods. This condition can result from hormonal imbalances, particularly involving the hypothalamic-pituitary-ovarian axis, uterine pathology, or ovarian dysfunction. Unlike normal menstrual cycles which occur every 21-35 days, polymenorrhoea may cause significant inconvenience and potential anaemia due to frequent blood loss. Investigation typically includes hormonal assessment, pelvic examination, and sometimes endometrial sampling to determine the underlying cause.
Usage
Usage note: British spelling with 'rh' - American version is 'polymenorrhea'.
