Activity Description

Abnormal uterine bleeding is a broad term that describes irregularities in the menstrual cycle involving frequency, regularity, duration, and volume of flow outside of pregnancy. Up to one-third of women will experience abnormal uterine bleeding in their life, with irregularities most commonly occurring at menarche and perimenopause. A normal menstrual cycle has a frequency of 24 to 38 days and lasts 2 to 7, with 5 to 80 milliliters of blood loss. Variations in any of these 4 parameters constitute abnormal uterine bleeding. This activity reviews abnormal uterine bleeding diagnosis and treatment and explains the importance of an interprofessional approach to evaluating and treating abnormal uterine bleeding.

Target Audience

This activity has been designed to meet the educational needs of physicians, physician associates, nurses, pharmacists, and nurse practitioners.

Learning Objectives

At the conclusion of this activity, the learner will be better able to:

  • Summarize the etiologies of abnormal uterine bleeding that can be remembered with the acronym PALM-COEIN, explaining which specific etiologies are included in the "not otherwise classified" category.
  • Describe the epidemiology of abnormal uterine bleeding.
  • Explain the causes of abnormal uterine bleeding related to the structure of the uterus versus the clotting pathway and the disruption of the hypothalamic-pituitary-ovarian axis.
  • Review the role of the interprofessional team in collaborating to treat women with abnormal uterine bleeding.
