Medical Term for Heavy Periods
The medical term for heavy periods is "menorrhagia" or "heavy menstrual bleeding (HMB)." 1, 2
Definition
Menorrhagia is objectively defined as menstrual blood loss exceeding 80 mL per cycle, though it is more commonly described clinically as excessive menstrual bleeding that interferes with a woman's physical, emotional, and social wellbeing. 3, 4
In practical terms, heavy menstrual bleeding can be predicted by the presence of clots ≥1 inch in diameter, low ferritin levels, and "flooding" (requiring pad or tampon changes more frequently than hourly) 5
The American Heart Association defines urgent bleeding as that which saturates a large pad or tampon hourly for at least 4 consecutive hours 2
