Dysmenorrhoea is a descriptive term for several conditions that cause menstrual pain. While various grades of menstrual pain
occur commonly in the menstruating population, approximately 15% of this group of women experience sufficient pain and
discomfort to report to healthcare services.
Dysmenorrhoea is classified as either primary or secondary, and consideration should be given to a third type, i.e. once-off, at the
time of passing an endometrial cast.
Primary dysmenorrhoea is predominantly found in young women, is caused by prostaglandin activity, and responds well to oral
contraceptive use, as well as nonsteroidal anti-inflammatory drug medication.
Secondary dysmenorrhoea, which can occur in any age group, and appears as a consequence of other serious conditions, is the
main challenge. The most common other serious conditions include endometriosis, the use of intrauterine contraceptive devices,
pelvic infections, uterine adenomyosis, sometimes fibroids, and ovarian cysts. Clearly, these conditions must be considered,
diagnosed and treated to resolve the main complaint of dysmenorrhoea.
