Abnormal uterine bleeding (AUB) is a common diagnosis in the adolescent female population. In recent years, changes have been made to standardize nomenclature, evaluation and management of AUB in adolescents. The terms “abnormal uterine bleeding” and “heavy menstrual bleeding” have replaced terms including “dysfunctional uterine bleeding,” “menorrhagia,” “metrorrhagia”, and “menometrorrhagia.” Due to a high prevalence of these diagnoses in this population and resulting effects on quality of life, clinicians should understand and practice current evidence-based care, yet variability continues to exist. Evaluation should be focused on common etiologies of AUB in adolescents, namely non-structural causes, rather than those etiologies more common in adult females. The aim of this article is to review the existing definition, etiologies, pathophysiology, evaluation and management of AUB in adolescent females, with an emphasis on current universally accepted nomenclature and guidelines for use in clinical care.

异常子宫出血 (AUB) 是青春期女性人群的常见诊断。近年来，为了规范青少年 AUB 的命名、评估和管理，已经做出了一些改变。术语“异常子宫出血”和“大量月经出血”已经取代了包括“功能失调性子宫出血”、“月经过多”、“子宫出血”和“月经过多”在内的术语。由于这些诊断在该人群中的高患病率及其对生活质量的影响，临床医生应了解和实践当前的循证护理，但变异性仍然存在。评估应侧重于青少年 AUB 的常见病因，即非结构性原因，而不是那些在成年女性中更常见的病因。本文的目的是回顾现有的定义、病因、
