Dysfunctional uterine bleeding (DUB) is a common cause of abnormal uterine bleeding and its diagnosis depends upon excluding organic lesions of the reproductive tract. The workup of the patient requires a complete medical history, physical examination, studies for ovulation, and genital tissue sampling. Whereas DUB is a physiologic normal phenomenon in the early and late years of the reproductive cycle, it is a pathologic entity at other times and can result from mild emotional or physical diseases in the patient. Management requires periodic progesterone replacement, increased iron intake, and therapy for any disease that is detected. Generally, oral contraceptives are not indicated, and hysterectomy is rarely needed. If infertility is also a complaint, specific ovulation induction therapy may also be needed. Control of the bleeding abnormality is the expected therapeutic response, and failure to achieve this suggests that a specific genital organic lesion has been overlooked.
功能失调性子宫出血（DUB）是子宫异常出血的常见原因，其诊断依赖于排除生殖道的器质性病变。对患者的检查需要完整的病史、体格检查、排卵相关检查以及生殖组织取样。虽然DUB在生殖周期的早期和晚期是一种生理正常现象，但在其他时期则是一种病理状态，可能由患者轻微的情绪或身体疾病引起。治疗需要定期补充孕激素、增加铁摄入以及对检测出的任何疾病进行治疗。一般不建议使用口服避孕药，很少需要进行子宫切除术。如果患者还伴有不孕问题，可能还需要特定的促排卵治疗。预期的治疗效果是控制出血异常，若未能达到这一效果，则提示可能忽略了特定的生殖器官器质性病变。
