Diagnostic Approach and Management of Iron Deficiency Anemia Secondary to Menorrhagia

Clinical Presentation and Initial Assessment

  • Dyspnea on exertion and fatigue are classic manifestations of reduced oxygen-carrying capacity from anemia, as noted by the American Journal of Respiratory and Critical Care Medicine 1, 2

Diagnostic Evaluation

  • Pelvic ultrasound is recommended to evaluate for structural abnormalities including uterine fibroids or adenomyosis, as suggested by the Journal of the American College of Radiology 3

Cardiac Evaluation

  • An electrocardiogram (ECG) should be obtained if palpitations are frequent, associated with syncope, or inappropriately rapid, according to Circulation 4
  • Echocardiography is not indicated unless there are abnormal cardiac findings on physical examination or ECG abnormalities, as stated by the Journal of the American College of Radiology 5
  • The American College of Cardiology notes that palpitations in young women are frequently benign and related to hormonal fluctuations or anemia rather than structural heart disease 4

Management and Treatment

  • The American College of Cardiology recommends against pursuing extensive cardiac workup without first addressing the obvious cause of anemia from menorrhagia, as dyspnea and palpitations will likely resolve with iron replacement 1, 2
