What are the treatment options for a woman experiencing heavy menstrual bleeding, urinary leakage, anemia, and weight gain?

Management of Heavy Menstrual Bleeding with Urinary Leakage, Anemia, and Weight Gain

Start with combined oral contraceptives containing 30-35 μg ethinyl estradiol (with levonorgestrel or norgestimate) as first-line treatment for the heavy menstrual bleeding and anemia, while simultaneously addressing the urinary leakage with pelvic floor physical therapy and evaluating for underlying uterine pathology such as fibroids that may be causing both the bleeding and bulk symptoms. 1, 2

Initial Diagnostic Evaluation

Before initiating treatment, rule out specific underlying causes:

• Pregnancy testing - essential first step in any woman of reproductive age with abnormal bleeding 1
• Hemoglobin and ferritin levels - to quantify anemia severity and iron stores 3
• Pelvic ultrasound - to identify structural lesions (fibroids, polyps, adenomyosis) that commonly cause heavy bleeding and may contribute to urinary symptoms through mass effect 4, 5
• STI screening - particularly in reproductive-aged women before starting hormonal therapy 1
• Endometrial biopsy - if bleeding pattern has changed substantially or if patient is over 40 years old 4

The combination of heavy bleeding, urinary leakage, and weight gain raises concern for uterine fibroids causing both menorrhagia and bulk symptoms (bladder pressure). 5

First-Line Medical Management

For Heavy Menstrual Bleeding and Anemia

Initiate monophasic combined oral contraceptives containing 30-35 μg ethinyl estradiol with levonorgestrel or norgestimate, which decreases menstrual blood loss by inducing regular shedding of a thinner endometrium and improves anemia. 1, 2

Additional benefits include:

• Improvement in acne 1
• Reduced risk of endometrial and ovarian cancers 1, 2
• Does not increase infertility or breast cancer risk 2

Important safety consideration: Assess thrombotic risk factors before prescribing, as COCs increase venous thromboembolism risk three to fourfold (up to 4 per 10,000 woman-years). 2 Monitor blood pressure at follow-up visits. 2

Adjunctive Therapy for Acute Heavy Bleeding

If bleeding is severe or persistent despite COCs:

• Add NSAIDs (mefenamic acid or ibuprofen) for 5-7 days during bleeding episodes - reduces menstrual blood loss by 20-60% 1, 4
• Consider tranexamic acid - reduces blood loss by 20-60%, though FDA labeling warns against combined use with hormonal contraception due to increased thrombotic risk 6, 4

Critical pitfall: The FDA specifically warns that combined use of tranexamic acid with hormonal contraception increases thromboembolic risk, and recommends using effective alternative (nonhormonal) contraception during tranexamic acid therapy. 6 Therefore, if using tranexamic acid, do NOT combine with COCs - use sequentially or choose one approach.

For Urinary Leakage

The urinary leakage likely represents stress incontinence from pelvic floor weakness or urge incontinence from bladder pressure if fibroids are present:

• Refer for pelvic floor physical therapy as first-line treatment for stress incontinence
• If fibroids are confirmed on ultrasound and causing bulk symptoms, the urinary symptoms may improve with fibroid treatment

Management Algorithm Based on Ultrasound Findings

If No Structural Pathology Found:

1. Continue COCs for at least 3-6 months, as unscheduled bleeding is common initially and generally decreases with continued use 1
2. Reassure patient that irregular bleeding during first 3-6 months is not harmful 1
3. Add NSAIDs for 5-7 days during heavy bleeding episodes if needed 1
4. If bleeding persists beyond 6 months and remains unacceptable, consider switching to levonorgestrel-releasing IUD (LNG-IUS), which has efficacy comparable to endometrial ablation 4, 7

If Fibroids or Adenomyosis Found:

For patients NOT desiring future fertility:

The 2024 ACR guidelines provide clear hierarchy based on invasiveness and outcomes:

1. Levonorgestrel-releasing IUD (LNG-IUS) - first-line for heavy bleeding with fibroids, efficacy comparable to endometrial ablation or hysterectomy 4, 7

2. Uterine artery embolization (UAE) - if LNG-IUS fails or bulk symptoms persist:

   • Equally effective as myomectomy at reducing heavy bleeding at 4 years 5
   • Lower rates of new fibroid formation than myomectomy 5
   • Decreases fibroid size by >50% at 5 years 5
   • Shorter hospital stay and faster recovery than surgery 5
   • Important: Pregnancy is still possible after UAE, so counsel accordingly 5

3. Hysterectomy - definitive treatment but should be avoided if less invasive options available, as it carries increased long-term risks:

   • Elevated cardiovascular disease risk 5
   • Increased risk of osteoporosis and bone fracture 5
   • Increased dementia risk 5
   • Higher complication rates and longer recovery than UAE 5

For patients desiring future fertility:

• Myomectomy (laparoscopic or hysteroscopic depending on fibroid location) 5
• Avoid endometrial ablation and hysterectomy as these cause permanent infertility 5

Managing Breakthrough Bleeding on COCs

If heavy or prolonged bleeding persists after initial months:

1. Re-evaluate for underlying gynecological problems: new fibroids, polyps, STDs, pregnancy, or medication interactions 1
2. If no pathology found, add NSAIDs for 5-7 days during bleeding episodes 1
3. For extended/continuous COC regimens: Consider a 3-4 day hormone-free interval to temporarily induce bleeding, but NOT during first 21 days of use and not more than once per month 1, 2
4. If bleeding remains unacceptable: Counsel on alternative methods (LNG-IUS) and offer switch if desired 1

Addressing Weight Gain

Weight gain may be:

• Related to hormonal contraceptive use (though evidence is limited)
• Secondary to reduced activity from heavy bleeding and anemia
• Unrelated to menstrual issues

Management approach:

• Assess weight changes at follow-up visits 5
• Counsel women concerned about weight changes perceived to be associated with contraceptive method 5
• Consider switching to LNG-IUS if weight gain is attributed to systemic hormonal effects, as it has primarily local effects

Follow-Up Strategy

• No routine follow-up visit required for women on COCs 1, 2
• Advise patient to return for side effects, concerns, or desire to change methods 5
• At routine visits, assess satisfaction with method and any health status changes 1
• Monitor blood pressure 2
• Reassess hemoglobin/ferritin after 3 months to confirm anemia improvement

Long-Term Outcomes

Data from 10-year follow-up studies show that medical management initiated in primary care results in:

• Only 29% requiring surgical intervention (17% hysterectomy, 13% endometrial ablation) over 10 years 7
• 43% of women able to cease all medical treatments by 10 years (likely due to menopause) 7
• Sustained quality of life improvements in both treatment groups 7

This supports starting with medical management rather than proceeding directly to surgery. 7
