Endometriosis
Endometriosis occurs when endometrium-like tissue grows outside the uterus—on ovaries, fallopian tubes, peritoneum, or distant organs. These lesions respond to hormones, causing inflammation, scarring, and chronic pain. Early recognition can improve fertility outcomes and quality of life.
Causes & Risk Factors
- Retrograde menstruation and impaired immune clearance
- Genetics (first-degree relatives at higher risk)
- Hormonal and inflammatory dysregulation
- Early menarche, short cycles, heavy bleeding
- Low BMI, alcohol use, high-fat diet
- Coexisting autoimmune or inflammatory conditions
Symptoms
- Severe dysmenorrhea, pelvic/back pain before and during periods
- Pain with intercourse, bowel movements, or urination
- Heavy menstrual bleeding or spotting
- Infertility or difficulty conceiving
- Fatigue, bloating, nausea, diarrhea/constipation during flares
Diagnosis
- Clinical evaluation plus symptom history
- Pelvic exam for nodules or adnexal masses
- Transvaginal ultrasound to detect endometriomas; MRI for deep infiltrating disease
- Definitive diagnosis via laparoscopy with histology
- Rule out other causes: fibroids, adenomyosis, IBS, interstitial cystitis
Staging (ASRM I–IV)
Based on lesion number, depth, and adhesions. Stage doesn’t always correlate with pain level.
Treatment & Management
Medical Therapy
- NSAIDs for pain (best started before menses)
- Hormonal suppression: combined oral contraceptives, progestin-only pills, LNG-IUD, depot medroxyprogesterone
- GnRH agonists/antagonists (leuprolide, elagolix) ± add-back therapy
- Aromatase inhibitors for refractory cases (often with progestin)
Surgical Options
- Laparoscopic excision/ablation of endometriotic implants
- Adhesiolysis to restore anatomy and fertility
- Ovarian endometrioma cystectomy
- Hysterectomy with oophorectomy in severe, refractory disease after childbearing
Lifestyle & Support
- Anti-inflammatory diet, limit alcohol/caffeine
- Regular exercise and pelvic-floor physical therapy
- Heat therapy, TENS units, acupuncture
- Stress management, CBT, or trauma-informed therapy
- Fertility counseling; IVF may bypass tubal damage
Living with Endometriosis
- Track pain, bleeding, bowel/bladder symptoms, medications, and triggers
- Build a flare plan (rest, heat packs, medications, hydration)
- Advocate for yourself—endo often gets dismissed as “normal cramps”
- Seek multidisciplinary care (gynecology, GI, pelvic PT, mental health)
Complications
- Infertility or ectopic pregnancy
- Ovarian cyst rupture or torsion
- Bowel or urinary tract involvement
- Adhesions causing organ dysfunction
- Emotional distress, anxiety, depression
Research & Future Directions
Promising areas include noninvasive biomarkers, high-resolution imaging, immune-modulating therapies, and gene expression profiling to tailor treatment.
Experimental & Emerging Treatments
- Selective Progesterone Receptor Modulators (SPRMs): Investigated for pain control with fewer hypoestrogenic side effects.
- Immune & Anti-Angiogenic Therapies: Target cytokines (TNF-α, IL-6) or vascular growth to halt lesion expansion.
- High-Intensity Focused Ultrasound (HIFU): Noninvasive ablation of deep lesions or adenomyosis with MRI guidance.
- Stem Cell & Regenerative Approaches: Aim to repair pelvic tissue damage and prevent adhesion formation post-surgery.
