Reviewing with the Staff

The above mnemonic provides a reasonable, but not comprehensive, differential for abnormal uterine bleeding. This approach will be helpful to junior learners who want to ensure that they consider various causes of uterine bleeding. Advanced learners should have expanded differentials that are based on categorical clusters such the patient’s reproductive status (e.g. premenarchal, fertile, pregnant, postmenopausal) and/or categories of disease (e.g. reproductive tract disease, iatrogenic causes, systemic causes). Always remember that fertile females presenting to the emergency department with uterine bleeding should be considered pregnant until proven otherwise.
