Clinical Manifestations of Uterine Fibroids
Primary Symptom Categories
Uterine fibroids most commonly present with menorrhagia (heavy menstrual bleeding), which frequently leads to iron deficiency anemia, followed by bulk-related symptoms including pelvic pain, pressure, and urinary/bowel dysfunction. 1
Bleeding Symptoms
- Menorrhagia is the most frequent symptom of uterine fibroids, occurring in the majority of symptomatic patients 1
- Heavy menstrual bleeding often results in iron deficiency anemia, fatigue, and chronic tiredness 2, 3
- Abnormal uterine bleeding patterns may include prolonged or irregular menstrual cycles 2, 4
- Dysmenorrhea (painful menstruation) commonly accompanies the bleeding symptoms 1, 5
Bulk and Pressure Symptoms
- Pelvic pain and pressure represent cardinal manifestations, often described as bloatedness or fullness 1, 5
- Abdominal distension and increased abdominal girth occur with larger fibroids 2, 4
- Urinary urgency and frequency result from bladder compression by anterior fibroids 1, 5
- Constipation develops from posterior fibroid pressure on the rectum 1, 5
- Chronic vaginal discharge may occur in some patients 3
- Dyspareunia (painful intercourse) can be present 4, 3
Acute Complications Requiring Urgent Evaluation
- Acute severe pain from fibroid degeneration (infarction or hemorrhage) requires immediate assessment 5
- Torsion of pedunculated fibroids produces acute pain necessitating urgent imaging 5
- Prolapse of submucosal fibroids through the cervix causes acute pain and requires prompt evaluation 5
Reproductive Manifestations
- Impaired fertility may occur depending on fibroid size and location 1, 4
- Obstetric complications including pregnancy loss and conceiving difficulties 1, 3
- Adverse pregnancy outcomes in women with fibroids 3
Age-Related Symptom Patterns
- Fibroid-associated symptoms peak in the perimenopausal years and typically decline after menopause due to decreased circulating estrogen 1, 5
- In postmenopausal women, fibroids become the second most common cause of acute pelvic pain, accounting for more cases than in younger women 5
- The prevalence of fibroids increases with age, detectable in up to 80% of women by age 50 6
Asymptomatic Presentation
- Most fibroids are asymptomatic and require no treatment, making the true frequency underestimated as many women remain undiagnosed 2, 7
- The incidence of uterine fibroids in reproductive women ranges from 5.4% to 77% depending on the diagnostic method and population studied 3
Critical Clinical Pitfalls
- When acute pain develops, urgent imaging is warranted to exclude torsion, prolapse, or infarction/hemorrhage requiring intervention 5
- Contrast-enhanced CT demonstrates the best diagnostic performance for fibroid complications, with contrast enhancement showing 86% sensitivity and ascites showing 100% sensitivity 5
- In postmenopausal women with fibroids and persistent symptoms, maintain high suspicion for malignancy—endometrial biopsy is essential prior to intervention to rule out endometrial neoplasia and potentially diagnose sarcoma 1, 5
- Adenomyosis frequently coexists with fibroids (presenting with heavy menstrual bleeding, dysmenorrhea, and dyspareunia), which complicates pain patterns and increases treatment failure rates 8, 5
- Black women have higher incidence (exceeding 80% by age 50) and develop clinically significant disease at earlier ages compared to White women (approaching 70% by age 50) 1
