What is the difference between menorrhagia and menometrorrhagia?

Menometrorrhagia was once an umbrella term for two different conditions that sound nearly the same:

• Menorrhagia: excessive and/or prolonged menstruation.
• Metrorrhagia: excessive, prolonged and/or irregular bleeding unrelated to menstruation.

In 2011, the International Federation of Gynecology and Obstetrics (FIGO) changed the names to prevent confusion. Menorrhagia is now called heavy menstrual bleeding. Menometrorrhagia is now called abnormal uterine bleeding.
