How is menorrhagia defined?

Menorrhagia is defined as excessive menstrual bleeding, which is typically characterized by prolonged menstrual bleeding lasting longer than 7 days or a total blood loss of more than 60 ml during menstruation. This definition is crucial for health care providers to identify and treat women who may be experiencing significant menstrual blood loss, which could lead to anemia or have other underlying health implications.

The parameters of 7 days and the 60 ml threshold help clinicians determine when a patient's menstrual bleeding is abnormal and warrants further investigation or management. Understanding menorrhagia is important for the appropriate diagnosis and treatment of menstrual disorders, as well as for educating patients about what constitutes normal versus abnormal menstrual cycles.

Other options describe different forms of menstrual irregularities or conditions; for example, irregular bleeding refers to unpredictable menstrual cycles or abnormal timing of periods, which does not specifically relate to the volume or duration of bleeding that defines menorrhagia. Similarly, the absence of menstruation for 6 months describes amenorrhea, while menses longer than 14 days suggests a different condition but does not provide the accepted definition for menorrhagia. Hence, the correct choice clearly delineates the criteria for identifying this specific menstrual disorder.
