Watch to the HELP Group members talking about their mission.

Heavy menstrual bleeding (HMB) is the most common presentation of abnormal uterine bleeding and affects up to 30% of women at some point in their lives.1,2 HMB can negatively influence a woman’s physical, emotional, social and material quality of life;1 however, the majority of affected women do not realise their bleeding is abnormal.


The HELP Group have created this website to provide a comprehensive educational resource to identify HMB, diagnose, and counsel on effective therapeutic options. By expanding your knowledge of HMB, you can have better consultations with your patients and help find appropriate treatments to improve their lives.

The Terminology of Heavy Menstrual Bleeding

One of the key issues surrounding abnormal menstrual bleeding (AUB) and heavy menstrual bleeding is the inconsistency in the nomenclature used when describing symptoms and causes.1


The Menstrual Disorders Working Group was set up by the International Federation of Gynecology and Obstetrics (FIGO) to address the issues associated with the terminology in this area and to develop consistent, universally accepted terminology that can be used by clinicians, investigators and patients to facilitate communication, clinical care, and research.1


Extensive international discussion has led to the recommendation that terms such as ‘menorrhagia’ should be discarded, as they are poorly defined and confusing.1 Instead, simple and clear terminology such as ‘abnormal uterine bleeding’ and ‘heavy menstrual bleeding’ should be used.1


AUB is a significant clinical entity and is the overarching term used to describe any departure from normal menstruation.1


HMB is not an alternative term for AUB but it is the most common clinical manifestation, affecting up to 30% of women at some point in their lives.1,2

Heavy Menstrual Bleeding word cloud

HMB is defined as excessive menstrual blood loss that interferes with a woman’s physical, emotional, social, and material quality of life.1 It is important to recognize that HMB is not a diagnosis, but rather a symptom: a starting point in the search for a diagnosis.1
