What does menorrhagia mean?
Menorrhagia is the medical term for excessive or prolonged bleeding during menstruation. It can involve unusually heavy flow, repeated bleeding that soaks through products, or periods that last longer than expected, and it may lead to fatigue, weakness, or anemia when substantial blood is lost. The term is used by clinicians and in medical literature, while “heavy menstrual bleeding” is the more accessible expression in general health information. Menorrhagia is distinct from dysmenorrhea, which primarily describes menstrual pain, and from broader conditions involving bleeding both during and between periods. Although it is sometimes treated as a symptom rather than a single disease, persistent or severe menstrual bleeding can indicate an underlying condition and should be medically assessed. The word combines Greek roots associated with the menstrual month and the flow of blood.

Where does menorrhagia come from?
Menorrhagia combines the Greek roots mēn, meaning “month,” and rhein, meaning “to flow.” Its development reflects the medical description of excessive flow during menstruation. It is related etymologically to words such as menstrual and menses, while its second element belongs to the same Greek root found in hemorrhage.
