Definition of Amenorrhea
Amenorrhea: Absence or cessation of menstruation. Amenorrhea is conventionally divided into primary and secondary amenorrhea.
The absence of menstruation during pregnancy is a form of physiologic secondary amenorrhea, physiologic in the sense that it is completely normal and is not caused by anything medically harmful (pathologic). Amenorrhea during lactation is another type of physiologic secondary amenorrhea.
The word "amenorrhea" is compounded from three Greek roots "a-", no + "men", month + "rhoia", flow = no monthly flow. Amenorrhea is less commonly called amenia.Source: MedTerms™ Medical Dictionary
