Long Menstrual Periods (Menorrhagia)
Long menstrual periods, medically termed menorrhagia, involve bleeding that lasts longer than 7 days or is so heavy it interferes with daily life. While normal periods typically last 3-7 days, prolonged bleeding affects up to 30% of women at some point. This condition can lead to anemia, fatigue, and significantly impact quality of life. Understanding the difference between normal variation and concerning patterns helps identify when extended bleeding requires medical evaluation and treatment.
⚠️ Seek Medical Attention For:
- Bleeding lasting more than 7 days
- Soaking through pad/tampon every hour
- Passing blood clots larger than a quarter
- Severe cramping or pelvic pain
- Signs of anemia (fatigue, dizziness, shortness of breath)
- Bleeding between periods
- Bleeding after menopause
- Sudden change in menstrual pattern
- Fainting or severe weakness
- Fever with heavy bleeding
Understanding Long Menstrual Periods
Menorrhagia is defined as menstrual bleeding lasting longer than 7 days or blood loss exceeding 80ml per cycle (though this is difficult to measure). The condition often overlaps with heavy menstrual bleeding, as prolonged periods typically involve excessive blood loss. Normal menstrual flow should not interfere with daily activities or cause anemia.
The menstrual cycle is controlled by complex hormonal interactions. When these are disrupted, or when structural problems exist in the uterus, bleeding can become prolonged or excessive. Age plays a role too - abnormal bleeding is more common during adolescence and perimenopause when hormones fluctuate most.
Common Causes
Structural Causes
- Uterine fibroids
- Endometrial polyps
- Adenomyosis
- Endometrial hyperplasia
- Uterine or cervical cancer
- IUD complications
Hormonal Imbalances
- Anovulation (no ovulation)
- Polycystic ovary syndrome (PCOS)
- Thyroid disorders
- Perimenopause
- Obesity effects
- Stress-related changes
Blood Disorders
- Von Willebrand disease
- Platelet disorders
- Clotting factor deficiencies
- Leukemia
- Thrombocytopenia
- Liver disease effects
Other Causes
- Medications (anticoagulants)
- Endometriosis
- Pelvic inflammatory disease
- Pregnancy complications
- Chronic medical conditions
- Extreme weight changes
Signs of Excessive Menstrual Bleeding
- Duration: Bleeding lasting more than 7 days
- Flow rate: Changing protection every 1-2 hours
- Night changes: Waking to change pads/tampons
- Double protection: Using both pads and tampons
- Clots: Passing clots larger than 1 inch
- Flooding: Sudden gushes of blood
- Lifestyle impact: Canceling activities due to bleeding
- Anemia symptoms: Fatigue, weakness, pallor
Age-Related Considerations
Adolescents
- Anovulatory cycles common first 2 years
- May indicate bleeding disorders
- Important to screen early
- Can impact school and activities
Reproductive Years
- Structural causes more common
- Pregnancy complications possible
- Hormonal contraceptives may help
- Fertility considerations important
Perimenopause
- Hormonal fluctuations increase
- Anovulatory cycles common
- Cancer risk increases
- Requires careful evaluation
Impact on Daily Life
Physical Effects
- Iron deficiency anemia
- Chronic fatigue
- Shortness of breath
- Dizziness and headaches
- Rapid heartbeat
- Difficulty concentrating
Emotional/Social Impact
- Anxiety about bleeding through
- Missing work or school
- Avoiding social activities
- Impact on intimate relationships

Medical Evaluation
Medical History
- Menstrual cycle patterns
- Bleeding diary/calendar
- Associated symptoms
- Medication history
- Family history of bleeding
- Impact on daily life
Physical Examination
- Pelvic examination
- Signs of anemia
- Thyroid assessment
- Body hair patterns (hormones)
- Bruising or bleeding signs
Diagnostic Tests
- Blood tests: CBC, iron studies, thyroid, hormones
- Coagulation studies: Bleeding disorders
- Ultrasound: Uterine structure
- Endometrial biopsy: If over 45 or risk factors
- Hysteroscopy: Direct visualization
- MRI: For complex cases
Treatment Options
Medications

- Progesterone therapy
- GnRH agonists
Hormonal Options
- Combined oral contraceptives
- Progesterone-only pills
- Hormonal IUD (Mirena)
- Contraceptive patch/ring
- Depo-Provera injection
- Continuous hormone therapy
Procedures
- Endometrial ablation
- Uterine artery embolization
- Myomectomy (fibroid removal)
- Hysteroscopic polypectomy
- D&C (dilation and curettage)
- Focused ultrasound
Surgical Options
- Hysterectomy (definitive)
- Laparoscopic procedures
- Robotic surgery options
- Fertility-sparing approaches
- Treatment of underlying cause
Managing Long Periods
During Heavy Days
- Use highest absorbency products
- Set timers for changing
- Keep extra supplies handy
- Wear dark clothing
- Use waterproof mattress cover
- Consider menstrual cups
- Track blood loss
Lifestyle Adjustments
- Plan around heavy days
- Stay well hydrated
- Eat iron-rich foods
- Get adequate rest
- Gentle exercise when possible
- Stress management
- Join support groups
When to Seek Emergency Care
Go to emergency room if experiencing:
- Soaking through protection every hour for several hours
- Passing clots larger than golf balls
- Severe dizziness or fainting
- Rapid heartbeat with weakness
- Severe abdominal pain
- Signs of shock (cold, clammy, confused)
- Bleeding while pregnant
Long-term Management
- Regular monitoring: Track patterns and changes
- Annual check-ups: Screen for complications
- Treat anemia: Ongoing iron supplementation
- Fertility planning: Discuss with provider
- Quality of life: Don't accept suffering as normal
- Treatment adjustments: As needed over time
- Emotional support: Address impact on well-being
