Treatment of Heavy Menstrual Bleeding Due to Fibroids and Polyps
For heavy menstrual bleeding due to uterine fibroids and polyps, treatment should begin with medical management using a levonorgestrel-releasing intrauterine system (LNG-IUS) as first-line therapy, followed by minimally invasive procedures if medical management fails, with hysterectomy reserved as definitive treatment when other options are unsuccessful or contraindicated. 1
Medical Management Options
First-Line Treatments
- Levonorgestrel-releasing IUD (Mirena): Most effective hormonal option for bleeding control, significantly improving both pain and bleeding compared to other options 1
- Tranexamic acid: Reduces bleeding by 20-60%, taken only during menstruation 1, 2
- Contraindication: Active thromboembolic disease or history/risk of thrombosis 1
- NSAIDs: Can reduce bleeding by 20-40% 1, 2
- Combined oral contraceptives: Effective for controlling bleeding, especially with smaller lesions, but less effective than LNG-IUS 1
Second-Line Treatments
- GnRH agonists/antagonists: Reduce bleeding and lesion volume by 40-50% 1
- Limited to short-term use due to bone loss
- Add-back therapy can minimize side effects while maintaining efficacy
- Selective progesterone receptor modulators (SPRMs):
Surgical Management Options
For Polyps
- Hysteroscopic polypectomy: First-line surgical approach for endometrial polyps 3
- Simple, safe procedure with excellent outcomes
- Can be performed as outpatient procedure
For Fibroids
Hysteroscopic myomectomy: Indicated for submucosal fibroids 1, 4
- Offers shorter hospitalization and faster recovery
- Preferred for women desiring fertility preservation
Laparoscopic myomectomy: Beneficial for subserosal or intramural fibroids 1, 4
- Shorter hospital stays and faster recovery than open myomectomy
- Appropriate for women desiring fertility preservation
Open myomectomy: Preferred for multiple fibroids or very large uteri 1
- Associated with improved quality of life for up to 10 years
- Risk of uterine rupture during subsequent pregnancy
Minimally Invasive Procedures
Uterine Artery Embolization (UAE): Improves quality of life and symptom scores 1
- Short-term and long-term symptom improvement in 94% and 85% of patients, respectively
- Alternative to surgery for women who wish to preserve their uterus
Endometrial ablation: Effective for heavy bleeding with success rates comparable to hormonal IUS 2, 3
- Low operative morbidity
- Can be performed as outpatient procedure
Definitive Treatment
- Hysterectomy: Only definitive treatment with very high patient satisfaction 1, 5
- Completely eliminates risk of recurrence
- Should be performed using least invasive route possible (vaginal, laparoscopic, or robotic-assisted)
- Consider when other treatments have failed or are contraindicated
Treatment Selection Algorithm
Initial Assessment:
- Confirm diagnosis with pelvic examination and vaginal sonography
- Sonohysterography or hysteroscopy for reliable diagnosis of polyps and fibroids 2
First-line approach: Medical management
- LNG-IUS for most patients (especially if contraception also desired)
- Tranexamic acid or NSAIDs if hormonal methods contraindicated
If first-line fails or is contraindicated:
- For polyps: Proceed to hysteroscopic polypectomy
- For fibroids: Consider location and size
- Submucosal: Hysteroscopic myomectomy
- Subserosal/intramural: Laparoscopic myomectomy
- Multiple/large: Consider UAE or open myomectomy
If minimally invasive approaches fail or are contraindicated:
- Consider hysterectomy, especially for women who have completed childbearing
Important Considerations
- Up to 20% of women with heavy menstrual bleeding may have an underlying inherited bleeding disorder requiring additional investigation 3
- Preoperative medical therapy with GnRH agonists or SPRMs can increase hemoglobin levels, reduce fibroid volume, and decrease surgical blood loss 1
- Treatment selection should consider symptom severity, patient's age, fertility desires, and uterine size 1
- Regular monitoring of hemoglobin levels and lesion size with imaging is recommended before and after treatment 1
