What are Uterine Fibroids?
Uterine fibroids, also called myomas, fibromas, or leiomyomas, are benign (noncancerous) tumors that grow in or on the uterus. They are among the most common tumors in women of reproductive age, affecting 30-40% of women by age 40, with even higher rates in African American women.
While many fibroids cause no symptoms and are discovered incidentally, they can sometimes become quite large and lead to heavy menstrual bleeding, severe abdominal pain, and complications affecting fertility and pregnancy.
The good news is that fibroids are benign and never become cancerous. Multiple effective treatment options exist ranging from observation to medical management to surgery, depending on fibroid size, location, symptoms, and fertility desires.
Common Symptoms
Heavy menstrual bleeding
Prolonged menstrual periods (>7 days)
Blood clots during menstruation
Severe menstrual cramping
Pelvic pain or pressure
Pain during sexual intercourse (dyspareunia)
Increased urinary frequency
Urinary urgency
Constipation
Leg pain or lower back pain
Abdominal bloating
Fullness or heaviness in lower abdomen
Types of Uterine Fibroids
Fibroids are classified by their location within or on the uterus. The type determines symptoms, treatment options, and impact on fertility.
Submucosal Fibroids
Location: Project into the uterine cavity
Frequency: 5-10% of fibroids
Typical Symptoms: Heavy bleeding, prolonged periods, cramping
Fertility Impact: Can impair fertility; may prevent implantation
Key Feature: Extends into uterine cavity; most bleeding risk
Intramural Fibroids
Location: Within the uterine wall muscle
Frequency: 50-60% of fibroids (most common)
Typical Symptoms: Cramping, heavy bleeding, pelvic pressure
Fertility Impact: May affect fertility depending on size/location
Key Feature: Most common type; embedded in muscle
Subserosal Fibroids
Location: Extend outside uterus into pelvic cavity
Frequency: 30-40% of fibroids
Typical Symptoms: Pelvic pressure, pain, pressure on organs
Fertility Impact: Usually don't affect fertility
Key Feature: Can grow large; may affect nearby organs
Pedunculated Fibroids
Location: Attached to uterus by stalk
Frequency: 2-3% of fibroids
Typical Symptoms: Pain if stalk twists; variable symptoms
Fertility Impact: Usually don't affect fertility
Key Feature: Unique stalk attachment; risk of torsion
Cervical Fibroids
Location: Develop in cervix
Frequency: <1% of fibroids (rare)
Typical Symptoms: Vaginal discharge, bleeding, pain
Fertility Impact: Can block cervical canal; affect fertility
Key Feature: Rare location; unique management challenges
What Causes Uterine Fibroids?
While the exact cause of uterine fibroids remains incompletely understood, multiple factors play a role in their development. Unlike most cancers, fibroids result from complex interactions between genetic predisposition, hormonal factors, and growth signaling abnormalities.
Estrogen and Progesterone
Mechanism: Fibroids contain more estrogen and progesterone receptors than normal uterine muscle
Hormones stimulate fibroid growth; fibroids shrink after menopause
Role: Primary hormonal driver of fibroid development
Genetic Factors
Mechanism: Family history increases risk; inherited genetic predisposition
Women with affected mothers more likely to develop fibroids
Role: Genetic variations affect hormone receptor expression
Growth Factors
Mechanism: Alterations in growth factor signaling pathways
Abnormal growth factor production promotes fibroid proliferation
Role: Growth factors override normal growth inhibition
Extracellular Matrix (ECM) Abnormalities
Mechanism: ECM is expanded and altered in fibroids
Enhanced ECM increases fibroid stiffness and vascularity
Role: Hormone-mediated ECM remodeling
Uterine Injury or Inflammation
Mechanism: Uterine trauma triggers abnormal wound healing response
Inflammation and altered cytokine production promotes fibroids
Role: Inflammatory mediators interact with hormones
Altered Immune Response
Mechanism: Immune dysregulation allows fibroid growth
Reduced immune surveillance permits tumor proliferation
Role: Estrogen affects immune cell function
Angiogenesis (Blood Vessel Formation)
Mechanism: Increased vascular growth supports fibroid expansion
Extensive blood supply allows rapid fibroid growth
Role: Estrogen promotes vascular growth factor production
Stem Cell Recruitment
Mechanism: Bone marrow-derived stem cells recruited to uterus
Stem cells contribute to fibroid cell populations
Role: Hormones regulate stem cell homing
Who is at Risk?
Certain factors increase the likelihood of developing uterine fibroids. Understanding your risk helps guide prevention strategies and screening.
Age 30-50 Years
Fibroids most common in women during peak reproductive years
African American Ethnicity
Higher prevalence and earlier onset in African American women
Family History
Women with affected first-degree relatives at significantly higher risk
Obesity
Excess weight increases estrogen levels promoting fibroid growth
Early Menarche
Early menstruation onset increases lifetime estrogen exposure
High Red Meat Consumption
Processed and red meat consumption associated with increased risk
Low Vegetable/Fruit Intake
Inadequate plant-based diet increases fibroid risk
Vitamin D Deficiency
Low vitamin D levels associated with increased fibroids
Nulliparity (No Pregnancies)
Never having children increases fibroid risk
Hypertension
High blood pressure associated with fibroid development
Estrogen/Progesterone Therapy
Hormone therapy may increase fibroid growth
Sedentary Lifestyle
Lack of physical activity increases fibroid risk
Metabolic Syndrome
Insulin resistance and metabolic dysfunction promote fibroids
Uterine Instrumentation
Previous D&C, hysteroscopy, or instrumentation increases risk
Polycystic Ovary Syndrome (PCOS)
PCOS and associated hormonal imbalance increase fibroid risk
Symptom Severity and Impact
Symptom severity varies widely. Many women have no symptoms, while others experience significant quality of life impact. Severity helps guide treatment decisions.

Management: Emergency surgery; fibroid removal
How Uterine Fibroids are Diagnosed
Diagnosis combines clinical assessment with imaging studies. MRI provides the most detailed fibroid mapping for treatment planning.
Clinical History & Exam
Menstrual history, symptom assessment, pelvic examination findings
Transvaginal Ultrasound
High-resolution imaging from vaginal probe; excellent for fibroid detection and characterization
Transabdominal Ultrasound
Abdominal probe imaging; useful for larger fibroids and overall uterine assessment
Pelvic MRI
Gold standard for fibroid mapping; shows exact location, size, type for surgical planning
Hysterosalpingography (HSG)
X-ray with contrast; shows uterine cavity distortion from submucosal fibroids
Hysteroscopy
Direct visualization of uterine cavity; can assess submucosal fibroids and concurrent pathology
Hemoglobin/Hematocrit
Blood tests assess anemia severity from chronic blood loss
Iron Studies
Ferritin, TIBC assess iron stores and iron deficiency status
Pelvic CT
Alternative imaging if MRI contraindicated; less detailed than MRI
Sonohysterography
Ultrasound with saline infusion; excellent visualization of submucosal fibroids
Treatment Options
Treatment ranges from observation to minimally invasive procedures to surgery, depending on symptoms, fibroid characteristics, and fertility goals. Many options exist allowing individualized management.

How to Prevent or Reduce Fibroid Risk
While fibroids cannot always be prevented, lifestyle modifications may reduce risk, particularly in high-risk populations.
Maintain healthy body weight; obesity increases estrogen levels
Eat a diet rich in fruits and vegetables
Limit red meat and processed meat consumption
Maintain regular physical activity and exercise
Manage stress through relaxation techniques
Ensure adequate vitamin D intake; consider supplementation
Avoid unnecessary uterine instrumentation and procedures
Seek treatment for hormonal imbalances
Maintain healthy blood pressure
Avoid smoking; smoking affects estrogen metabolism
Limit alcohol consumption
Get adequate sleep and maintain healthy sleep patterns
Maintain healthy diet with adequate iron intake
Regular gynecological check-ups and screening
Discuss family history with healthcare provider
Managing Symptoms at Home
While medical and surgical treatments address the fibroids, these home care strategies help manage symptoms and improve quality of life.
Take prescribed medications exactly as directed
Use heat therapy (heating pad, warm bath) for cramping and pain
Maintain iron-rich diet (red meat, spinach, beans, fortified cereals)
Take iron supplements if anemia present; take with vitamin C
Stay well-hydrated; drink plenty of water
Rest during heavy bleeding days; don't overexert yourself
Practice stress reduction (meditation, yoga, deep breathing)
Regular moderate exercise; avoid strenuous activity during heavy periods
Keep track of menstrual bleeding and symptoms in diary or app
Wear appropriate menstrual protection (super tampons, pads, menstrual discs)
Sleep with extra pillow for comfort; elevate legs if pelvic pressure
Use NSAIDs preventatively starting before period begins
Avoid prolonged sitting if pelvic pressure significant
Maintain regular gynecological follow-up appointments
Discuss treatment options with healthcare provider regularly
When to Seek Medical Care
Certain symptoms warrant prompt medical evaluation and possible emergency care.
Severe Bleeding
Soaking through pads/tampons hourly; heavy clots requiring emergency care
Severe Anemia Symptoms
Severe fatigue, shortness of breath at rest, severe dizziness or syncope
Acute Severe Pain
Sudden severe abdominal or pelvic pain suggesting torsion or red degeneration
Fever with Pain
Fever accompanying pelvic pain suggests infection or red degeneration
Pregnancy with Fibroids
