What Should You Do If You Suspect Endometriosis?

See a gynecologist, ideally one specializing in endometriosis. Describe your symptoms in detail including pain severity, timing, and impact on daily life. Request a thorough clinical examination and expert transvaginal ultrasound. Don't accept that severe period pain is 'normal' — endometriosis pain that interferes with daily activities warrants investigation and treatment.

Strong Evidence2022 ESHRE Endometriosis Guideline provides evidence-based recommendations supporting clinical diagnosis and treatment initiation.

The average diagnostic delay for endometriosis is 7-10 years, largely due to normalization of menstrual pain by patients, family, and healthcare providers. A landmark study by the World Endometriosis Research Foundation found that symptom normalization by both patients and physicians was the primary barrier to timely diagnosis. The 2022 ESHRE (European Society of Human Reproduction and Embryology) guideline emphasizes that clinical diagnosis is acceptable for initiating treatment without requiring surgical confirmation.

Expert transvaginal ultrasound (TVS) in the hands of trained sonographers can detect ovarian endometriomas, deep infiltrating endometriosis of the rectovaginal septum, uterosacral ligaments, bladder, and bowel with high accuracy. A systematic review found expert TVS has sensitivity of 93% and specificity of 96% for ovarian endometriomas. MRI is complementary for mapping deep infiltrating disease, particularly when surgical planning is needed. Serum CA-125 is not recommended for diagnosis due to poor sensitivity and specificity.

What Is Endometriosis?

Endometriosis is a chronic inflammatory condition where tissue similar to the uterine lining grows outside the uterus, most commonly on the ovaries, fallopian tubes, pelvic peritoneum, and bowel. These endometrial-like implants respond to hormonal cycles, causing inflammation, adhesions, and pain. It affects approximately 10% of reproductive-age women.

The pathogenesis of endometriosis is not fully understood, but the leading theory is retrograde menstruation (Sampson's theory) — menstrual tissue flows backward through the fallopian tubes into the pelvis, where it implants and grows. However, since most women experience some retrograde menstruation, additional factors must explain why only some develop endometriosis. Immune dysfunction, genetic predisposition (heritability estimated at 50%), stem cell migration, and epigenetic factors all play roles.

Endometriosis is classified by the revised ASRM (American Society for Reproductive Medicine) staging system from Stage I (minimal) to Stage IV (severe), based on the location, extent, and depth of implants and adhesions. However, staging correlates poorly with symptom severity — Stage I disease can cause excruciating pain while Stage IV may be minimally symptomatic. The newer ENZIAN classification system better describes deep infiltrating endometriosis anatomy for surgical planning.

How Is Endometriosis Treated?

Treatment is individualized based on primary symptoms and reproductive goals. For pain: NSAIDs, hormonal therapy (combined OCs, progestins, GnRH agonists/antagonists), and laparoscopic excision surgery. For fertility: surgical excision of endometriomas and adhesions, and IVF. A multidisciplinary approach combining medical, surgical, and supportive therapies provides the best outcomes.

Strong EvidenceRandomized trials and ESHRE guideline provide strong evidence for both hormonal therapy and excision surgery in endometriosis management.

Hormonal therapy is the mainstay of medical management. Combined oral contraceptives (continuous use) suppress ovulation and endometrial growth. Progestins (dienogest 2 mg daily, norethindrone acetate, medroxyprogesterone) provide effective pain relief in 60-80% of patients. GnRH agonists (leuprolide) create a temporary menopause-like state and are highly effective but limited to 6-12 months due to bone density loss. The newer oral GnRH antagonist elagolix (Orilissa) allows dose-dependent estrogen suppression with fewer menopausal side effects.

Laparoscopic excision surgery, where endometriotic implants are carefully cut out rather than burned (ablated), provides superior long-term pain relief. A randomized trial found excision surgery reduced dysmenorrhea by 60-80% at 5-year follow-up. For endometriomas, cystectomy (removing the cyst wall) is preferred over drainage and ablation for both pain relief and fertility outcomes. Complete surgical excision by an experienced endometriosis surgeon at a specialized center provides the best results.

When Should You See a Doctor for Endometriosis?

See a doctor if you experience period pain that interferes with daily activities, pelvic pain between periods, pain during intercourse, pain with bowel movements or urination during periods, difficulty conceiving after 12 months, or heavy menstrual bleeding. These symptoms are not normal and warrant evaluation.

Seek an endometriosis specialist or experienced gynecologist rather than a general practitioner for suspected endometriosis, as the condition requires expertise for both diagnosis and management. Endometriosis foundation websites maintain directories of qualified specialists. Prepare for your appointment by documenting symptom patterns, pain severity (using a pain scale), impact on work and daily activities, and family history — endometriosis has a strong genetic component with 5-7 fold increased risk in first-degree relatives.

Emergency care should be sought for sudden severe pelvic pain (which may indicate endometrioma rupture), symptoms of bowel obstruction if endometriosis involves the bowel, or urinary retention. Long-term management should include regular follow-up every 6-12 months to assess treatment effectiveness, monitor for disease progression, and address fertility planning when desired.
