title: Abnormal genital tract bleeding.
abstract: The etiology of abnormal genital tract bleeding encompasses a wide range of disorders that can be secondary to anatomic changes of the female genital tract, infection, endocrinologic disorders, malignancies, and systemic illness. Appropriate workup is guided by age-related differential diagnoses for abnormal bleeding. Modern diagnostic tools can quickly focus the evaluation and allow timely intervention. Most abnormal genital tract bleeding is uterine bleeding, which is one of the most common gynecologic problems that health care providers will face. It accounts for approximately 15% of office visits and 25% of gynecologic operations. Abnormal uterine bleeding in reproductive-age women is defined as bleeding at abnormal or unexpected times or by excessive flow at the time of an expected menses. The average menstrual cycle length and duration of flow is 28 days and 4 days, respectively, with an average blood loss of 35 cc (1). Any bleeding should be considered abnormal in premenarchal girls and in post-menopausal women except for those with predictable withdrawal bleeding taking hormone replacement therapy. This article will review the categories of abnormal genital tract bleeding and the diagnostic tools needed to establish the correct diagnosis. Common clinical cases will be presented to illustrate the presenting symptoms, differential diagnoses, workup, treatment, and long-term follow-up.
