what does secondary amenorrhea mean
Amenorrhea is the medical term for the absence of menstruation. âSecondaryâ refers to menstruation that has occurred at least once but has stopped, typically for six months or longer. This is different from primary amenorrhea, a condition in which a woman does not have her first period by the age of 16.
1 Secondary amenorrhoea is where an established menstruation has ceasedâfor three months in a woman with a history of regular cyclic bleeding, or nine months in a woman with a history of irregular periods. 2  This usually happens to women aged 40â55.
