Abnormal Uterine Bleeding
Comprehensive Nursing Assessment & Management Guide
Overview & Definition
Abnormal uterine bleeding represents one of the most common gynecological concerns encountered in clinical practice, affecting approximately 14-25% of women of reproductive age. This condition encompasses any deviation from normal menstrual patterns, including changes in frequency, duration, volume, or regularity of menstrual cycles.
As nursing professionals, understanding abnormal uterine bleeding is crucial for providing comprehensive women’s health care. The condition significantly impacts quality of life, causing physical discomfort, emotional distress, and potential complications such as anemia or infertility. Early recognition and appropriate nursing interventions can dramatically improve patient outcomes and prevent serious complications.
Clinical Definition
Abnormal uterine bleeding is defined as bleeding from the uterine corpus that differs from normal menstruation in frequency, regularity, duration, or volume. This includes bleeding that occurs outside the normal menstrual cycle or bleeding patterns that deviate significantly from the individual’s established menstrual pattern.
FIGO Classification System
The International Federation of Gynecology and Obstetrics (FIGO) established a comprehensive classification system for abnormal uterine bleeding, providing standardized terminology that enhances communication among healthcare providers and improves patient care consistency.
| Classification Category | Definition | Clinical Examples |
|---|---|---|
| Heavy Menstrual Bleeding | Excessive menstrual blood loss interfering with quality of life | Flow >80ml per cycle, changing protection hourly |
| Intermenstrual Bleeding | Bleeding between regular menstrual periods | Spotting mid-cycle, breakthrough bleeding |
| Postmenopausal Bleeding | Any bleeding 12+ months after menopause | Vaginal bleeding in postmenopausal women |
| Irregular Menstruation | Unpredictable timing of menstrual cycles | Cycles varying >20 days from norm |
Acute Abnormal Uterine Bleeding
Episodes requiring immediate intervention to prevent further blood loss. Often presents with hemodynamic instability and requires urgent medical attention.
Chronic Abnormal Uterine Bleeding
Bleeding patterns that have been abnormal for most of the previous 6 months. Allows for systematic evaluation and planned management approaches.
Causes & Etiology – PALM-COEIN Framework
The PALM-COEIN classification system provides a systematic approach to understanding the various causes of abnormal uterine bleeding. This framework divides causes into structural (PALM) and non-structural (COEIN) categories, facilitating comprehensive assessment and targeted treatment.
PALM – Structural Causes
P – Polyps
Endometrial or cervical polyps causing irregular bleeding patterns
A – Adenomyosis
Endometrial tissue growing into uterine muscle wall
L – Leiomyomas
Uterine fibroids affecting menstrual flow and duration
M – Malignancy/Hyperplasia
Endometrial cancer or atypical hyperplasia
COEIN – Non-Structural Causes
C – Coagulopathy
Inherited or acquired bleeding disorders
O – Ovulatory Dysfunction
Hormonal imbalances affecting ovulation
E – Endometrial
Primary endometrial disorders
I – Iatrogenic
Medication-related bleeding
N – Not Yet Classified
Other rare or undefined causes
Common Risk Factors
Reproductive Factors
- • Early menarche or late menopause
- • Nulliparity or low parity
- • PCOS or metabolic disorders
Medical Conditions
- • Thyroid dysfunction
- • Diabetes mellitus
- • Liver or kidney disease
Lifestyle Factors
- • Obesity or rapid weight changes
- • Excessive exercise
- • Stress and psychological factors
Comprehensive Nursing Assessment
Systematic nursing assessment of abnormal uterine bleeding requires thorough history-taking, physical examination, and careful documentation. The assessment should focus on characterizing bleeding patterns, identifying potential causes, and evaluating the impact on the patient’s physical and emotional well-being.
Menstrual History Assessment
Cycle Characteristics
Frequency, duration, volume, and regularity patterns
Timing Patterns
Onset, interval changes, relationship to activities
Flow Assessment
Quantification using standardized tools and patient reports
Associated Symptoms
Pain Assessment
Dysmenorrhea, pelvic pain, cramping intensity
Systemic Symptoms
Fatigue, weakness, dizziness, syncope
Impact on Quality of Life
Work, social activities, sexual function, emotional health
| Assessment Component | Key Questions | Clinical Significance |
|---|---|---|
| Bleeding Pattern | How often? How long? How heavy? Clots present? | Helps classify type of abnormal uterine bleeding |
| Reproductive History | Pregnancies, births, contraceptive use, sexual activity | Identifies pregnancy-related and contraceptive causes |
| Medical History | Chronic conditions, medications, previous procedures | Reveals underlying systemic causes |
| Family History | Bleeding disorders, cancer, reproductive issues | Identifies genetic predispositions and risk factors |
Diagnostic Workup & Laboratory Studies
Comprehensive diagnostic evaluation of abnormal uterine bleeding involves a systematic approach combining laboratory studies, imaging, and specialized procedures. The extent of workup depends on patient age, bleeding severity, and clinical presentation.
Initial Laboratory Panel
- Complete Blood Count (CBC)
- Iron studies and ferritin
- Pregnancy test (βhCG)
- Thyroid function tests
- Coagulation studies (if indicated)
Imaging Studies
- Transvaginal ultrasound
- Saline infusion sonography
- MRI (if indicated)
- Hysteroscopy
- CT scan (specific cases)
Specialized Procedures
- Endometrial biopsy
- Dilation and curettage
- Hysteroscopic evaluation
- Cervical cytology
- Endocrine evaluation
Age-Specific Diagnostic Considerations
Adolescents
Focus on bleeding disorders, pregnancy, and anovulation. Structural causes less common.
Reproductive Age
Rule out pregnancy, assess for structural and hormonal causes, consider malignancy risk factors.
Postmenopausal
High priority for endometrial sampling to rule out malignancy and precancerous conditions.
Treatment Management Approaches
Management of abnormal uterine bleeding follows a stepwise approach, beginning with conservative measures and progressing to more invasive interventions based on symptom severity, patient preferences, and treatment response. The goal is to restore normal bleeding patterns while preserving fertility when desired.
Medical Management
Hormonal Therapies
- • Combined oral contraceptives
- • Levonorgestrel intrauterine system
- • Progestin therapy (oral, injectable)
- • GnRH agonists (short-term use)
Non-Hormonal Options
- • Tranexamic acid (antifibrinolytic)
- • NSAIDs (mefenamic acid, ibuprofen)
- • Iron supplementation
- • Desmopressin (bleeding disorders)
Surgical Interventions
Minimally Invasive
- • Endometrial ablation
- • Hysteroscopic polypectomy
- • Myomectomy (hysteroscopic, laparoscopic)
- • Uterine artery embolization
Definitive Procedures
- • Total hysterectomy
- • Bilateral salpingo-oophorectomy
- • Radical procedures (malignancy)
| Treatment Approach | Indications | Effectiveness | Considerations |
|---|---|---|---|
| Levonorgestrel IUS | Heavy menstrual bleeding, contraception desired | 80-90% reduction in bleeding | Initial irregular bleeding, long-term contraception |
| Tranexamic Acid | Heavy bleeding, contraception not needed | 40-50% reduction in bleeding | Taken during menstruation only, well-tolerated |
| Endometrial Ablation | Completed childbearing, failed medical therapy | 85% satisfaction rate | Contraception required, pregnancy dangerous |
| Hysterectomy | Failed conservative treatment, patient preference | 100% effective for bleeding | Major surgery, loss of fertility, hormone considerations |
Evidence-Based Nursing Interventions
Nursing care for patients with abnormal uterine bleeding extends beyond medication administration to include comprehensive holistic care, patient advocacy, education, and psychosocial support. Effective nursing interventions can significantly improve patient outcomes and quality of life.
Acute Care Interventions
Hemodynamic Monitoring
Assess vital signs, orthostatic changes, signs of hypovolemia
IV Access & Fluid Management
Establish IV access, fluid resuscitation, blood product administration
Bleeding Assessment
Quantify blood loss, monitor pad counts, clot assessment
Ongoing Care Management
Medication Management
