PY - 2018 T2 - Reichman's Emergency Medicine Procedures, 3e AB - Uterine bleeding may occur in the absence of current or recent pregnancy, during pregnancy, or in the postpartum period.1 Abnormal uterine bleeding (AUB) is a term that defines menstrual bleeding that occurs on an abnormal schedule, for an abnormal duration of time, or with an abnormal quantity of blood loss.2-6 The term dysfunctional uterine bleeding is no longer used.7,8 Dysfunctional uterine bleeding is a general term that was used to describe irregular bleeding in the nonpregnant patient. AUB can manifest as heavy menstrual bleeding (HMB). HMB is cyclical or ovulatory bleeding and was previously termed menorrhagia. Intermenstrual bleeding (IMB) refers to bleeding that occurs between menses. This was previously termed metrorrhagia. IMB often has a cervical etiology. Approximately 3% of women have physiologic IMB associated with ovulation.9 Approximately 66% of women who have had one or more cesarean births have a defect in the uterus. This is reported as regular postmenstrual spotting.10 Irregular AUB is caused by ovulatory dysfunction (AUB-O) and is often reported as no cycle for 2 to 3 months. When cycles occur, they are often heavy. SN - PB - McGraw-Hill Education CY - New York, NY Y2 - 2024/03/29 UR - accessemergencymedicine.mhmedical.com/content.aspx?aid=1159806303 ER -
