The monthly discharge of blood and other substances from the uterus in women and female mammals, commonly known as menstruation.
Many women experience various symptoms during their catamenia.
Catamenia is derived from the Greek "kata" (meaning down) and "men" (meaning month). The term refers to the monthly cycle of menstruation in females, thus combining the idea of a monthly occurrence that comes down.
Think of the word 'kata' meaning down and 'men' relating to month, which helps you remember that catamenia refers to the monthly cycle.
