Menorrhagia, clinically defined as heavy menstrual bleeding (HMB), is a common gynecological complaint among women of reproductive age. In standard midwifery practice, it is traditionally quantified as blood loss exceeding 80 milliliters per cycle, or menses lasting longer than seven days. However, actual measurement is rarely practical in clinical settings. Therefore, subjective indicators hold significant value. If a woman regularly passes blood clots larger than a coin, soaks through one or more sanitary pads every hour for several consecutive hours, or finds her daily activities severely restricted by her period, she is experiencing menorrhagia.
This excessive bleeding disrupts physical, social, and emotional well-being. Chronic blood loss frequently depletes iron stores, leading to iron deficiency anemia. Midwives must recognize that many women normalize heavy bleeding because it has been a lifelong pattern or shared family experience, making careful questioning during routine health histories essential.
The causes of menorrhagia are broad, categorized structurally or systemically using the international PALM-COEIN classification system. Structural anomalies, grouped under PALM, include polyps, adenomyosis, leiomyomas (uterine fibroids), and malignancy or hyperplasia. These conditions alter the uterine cavity, increase the surface area of the endometrium, or interfere with normal myometrial contractility.
Non-structural causes, grouped under COEIN, include coagulopathies (such as von Willebrand disease), ovulatory dysfunction, endometrial disorders of local hemostasis, iatrogenic factors (like a copper intrauterine device), and conditions not yet classified. In adolescents, immature hypothalamic-pituitary-ovarian axes frequently cause anovulatory cycles, resulting in erratic, heavy bleeding episodes.
Evaluating a patient with menorrhagia begins with a thorough history focusing on menstrual patterns, contraceptive use, and family bleeding tendencies. Midwives perform a comprehensive physical examination, including a bimanual pelvic exam to check for uterine enlargement, tenderness, or irregular contours.
Essential diagnostic investigations include:
Treatment strategies for menorrhagia aim to reduce blood loss, correct anemia, and improve quality of life. Therapy is tailored to the patient's age, underlying cause, and desire for future fertility.
| Treatment Category | Common Examples | Primary Mechanism |
|---|---|---|
| Medical (Non-hormonal) | Tranexamic acid, NSAIDs | Promotes clotting / reduces prostaglandins |
| Medical (Hormonal) | Combined oral contraceptives, Levonorgestrel-IUS | Thins endometrium / suppresses ovulation |
| Surgical | Endometrial ablation, Myomectomy, Hysterectomy | Removes or destroys uterine tissue |
Non-hormonal options are ideal for women desiring pregnancy or who wish to avoid hormones. Hormonal treatments provide cycle control and significant reduction in flow. Surgical interventions are reserved for cases unresponsive to medical therapy or where large structural lesions are present.
Holistic care for a woman with menorrhagia extends beyond medical prescriptions to include active nutritional support and continuous education. Midwives must assess dietary iron intake and administer prescribed iron supplements, advising patients on how to minimize gastrointestinal side effects and enhance absorption using vitamin C.
Patients require guidance on tracking their menstrual cycles accurately, recognizing red-flag symptoms such as dizziness, severe cramping, or soaking more than two pads per hour, and knowing when to seek emergency care. Providing a safe, empathetic environment encourages women to discuss the impact of heavy bleeding on their daily lives, ensuring they remain active participants in their ongoing care plan.
