Re-definition and re-classification of menstrual disorders

Historically, the terminology used for abnormal uterine bleeding has been inconsistent and confusing. The Fédération Internationale de Gynécologie et d'Obstétrique (FIGO) has recently approved new definitions and a standardized classification system for menstrual disorders and other contributors to the problem of abnormal uterine bleeding. This article describes the need for these changes and aims to encourage their use in routine clinical practice, medical education and scientific research, with the hope that they will lead to improved reproductive healthcare for women.
