Abnormal Uterine Bleeding
Symptoms and Signs of AUB
Compared with typical menses, abnormal uterine bleeding may do the following (see table Normal Menstrual Parameters* [ Occur more frequently (menses < 24 days apart) Be irregular (cycle frequency varies ≥ 8 to 10 days) Involve more days of bleeding (> 8 days) Involve increased volume of blood loss (> 80 mL [or by patient report of volume]) during menses (heavy menstrual bleeding) Occur between menses (intermenstrual bleeding) Patients with ovulatory cycles usually have menstrual cycles that are occur at a normal frequency and are regular, but they may have heavy menstrual bleeding or intermenstrual bleeding. Symptoms that suggest a patient has ovulatory cycles include molimina (eg, cyclic breast tenderness, premenstrual bloating, or mood changes) and midcycle cramping pain (mittelschmerz). Daily body temperature (basal body temperature) increases slightly after ovulation and then decreases after the next menstrual cycle begins. Patients with AUB-O (ovulatory dysfunction) have uterine bleeding that occurs at unpredictable times, may vary widely in volume, and is not accompanied cyclic changes in basal body temperature. 1.Munro MG, Critchley HOD, Fraser ISfor the FIGO (International Federation of Gynecology and Obstetrics) Menstrual Disorders Committee): The two FIGO systems for normal and abnormal uterine bleeding symptoms and classification of causes of abnormal uterine bleeding in the reproductive years: 2018 revisions.Int J Gynaecol Obstet143 (3):393–408, 2018. doi: 10.1002/ijgo.12666 Epub 2018 Oct 10.
