Endometriosis

What Is Endometriosis?

Endometriosis is a chronic inflammatory condition in which tissue similar to the uterine endometrium grows outside the uterus, most commonly on the ovaries, fallopian tubes, peritoneal surfaces, and pelvic ligaments. This ectopic tissue responds to the menstrual cycle hormones, thickening and shedding with each cycle, but because the tissue is outside the uterus, the shed material has no exit. The result is chronic pelvic inflammation, adhesion formation, pain, and in many cases impaired fertility.

The condition affects approximately 10 percent of women of reproductive age, yet the average diagnostic delay from symptom onset to confirmed diagnosis is 7 to 10 years. This delay occurs because pelvic pain is frequently normalized, attributed to "bad periods," or misdiagnosed as irritable bowel syndrome. Estrogen dominance is the primary hormonal driver: excess estrogen relative to progesterone promotes endometrial tissue proliferation both inside and outside the uterus. Chronic inflammation, immune dysregulation, impaired estrogen detoxification through the liver and gut microbiome, and environmental endocrine disruptors all contribute to the hormonal and inflammatory environment that drives the condition.

Why Endometriosis Matters

Common Symptoms

Root Causes: A Functional Medicine Perspective

Endometriosis is driven by the convergence of hormonal, inflammatory, immune, and environmental factors that create the biological environment permitting ectopic endometrial growth.

Estrogen Dominance and Impaired Estrogen Metabolism

Estrogen dominance is the primary hormonal driver. Excess estrogen relative to progesterone stimulates endometrial tissue proliferation. Critically, the issue is not simply high estrogen production. It is impaired estrogen elimination: the liver's phase I and phase II detoxification pathways (particularly the 2-hydroxy estrone pathway favored over the 4-hydroxy and 16-hydroxy pathways) and the gut estrobolome (bacteria that metabolize estrogen) determine how efficiently estrogen is cleared. Impaired clearance recycles estrogen back into circulation, compounding the dominance. Detoxification impairment from MTHFR variants, nutrient deficiency, or gut dysbiosis directly contributes.

Chronic Inflammation and Immune Dysregulation

Endometriotic lesions produce their own inflammatory cytokines (IL-6, TNF-alpha, IL-1beta), creating a self-sustaining inflammatory loop. The pelvic immune environment in endometriosis patients shows impaired natural killer cell function, the immune cells responsible for clearing ectopic tissue. This immune surveillance failure permits endometrial implants to persist and grow rather than being identified and eliminated. Systemic inflammation from intestinal permeability and dietary triggers compounds the pelvic inflammation.

Gut Microbiome and the Estrobolome

The gut microbiome contains the estrobolome: the collection of bacteria that metabolize estrogen through beta-glucuronidase activity. When the estrobolome is dysbiotic, beta-glucuronidase activity increases, deconjugating estrogen that was already processed by the liver for elimination. This reactivated estrogen is reabsorbed into circulation, increasing the total estrogen burden. Gut restoration directly reduces the estrogen recycling that drives endometrial tissue growth.

Environmental Endocrine Disruptors

Dioxins, BPA, phthalates, and other xenoestrogens mimic estrogen at cellular receptors, compounding the estrogen dominance. These chemicals are ubiquitous in plastics, personal care products, and conventionally grown food. Reducing environmental estrogen exposure and supporting detoxification of accumulated toxins are modifiable interventions.

Conventional vs Functional Medicine Approach

Key Labs to Evaluate

How to Interpret These Labs Together

Common Patterns Seen in Patients

• The woman told her pain is "normal periods": 10 years of progressively worsening menstrual pain, now affecting 2 weeks per month. Three providers attributed it to "bad cramps." Estradiol-to-progesterone ratio severely imbalanced. hs-CRP 3.4. DUTCH test showing dominant 4-hydroxy estrone pathway. Gut analysis showing elevated beta-glucuronidase (estrogen recycling). Comprehensive intervention: DIM and sulforaphane for estrogen metabolism, progesterone support, anti-inflammatory protocol, gut restoration. Pain severity reduced by approximately 70 percent within 3 cycles.
• The infertility patient with "unexplained infertility": Two years of unsuccessful conception. HSG normal, ovulation confirmed. Laparoscopy reveals stage II endometriosis. The inflammatory pelvic environment was imparing egg quality, sperm transport, and implantation. Anti-inflammatory protocols, estrogen metabolism optimization, and progesterone support for 4 months preceding a subsequent IVF cycle, which was successful.
• The post-excision patient with recurrent symptoms: Laparoscopic excision 2 years ago provided 8 months of relief, then symptoms returned. No evaluation of estrogen metabolism, gut health, or inflammatory status before or after surgery. The lesions were removed but the biological environment that produced them was unchanged. Comprehensive hormonal, inflammatory, and gut evaluation identified persistent estrogen dominance from gut estrobolome dysbiosis and impaired liver detoxification. Treating the drivers prevented further surgical recurrence.

What Most Doctors Miss

• Estrogen metabolism is not evaluated: it is not sufficient to measure estradiol. The pathway through which estrogen is metabolized (2-OH vs 4-OH vs 16-OH) determines its proliferative impact. DUTCH testing reveals this critical information.
• The gut estrobolome is not assessed: dysbiotic gut bacteria recycle estrogen back into circulation, perpetuating the estrogen dominance. Gut restoration is one of the most impactful and most overlooked interventions for endometriosis.
• Surgery without metabolic correction leads to recurrence: removing lesions without correcting the hormonal and inflammatory environment that produced them results in 20 to 40 percent recurrence within 5 years.
• Insulin resistance is not connected to endometriosis: insulin resistance suppresses SHBG, increasing free estrogen availability. Metabolic evaluation should be part of every endometriosis assessment.

When to Seek Medical Care

If you experience severe menstrual cramps, chronic pelvic pain, pain with intercourse or bowel movements, heavy periods, or difficulty conceiving, evaluation for endometriosis and its hormonal and inflammatory drivers is warranted. Pain that progressively worsens with each cycle, or pain that requires missing work or daily activities, is not normal and should not be dismissed.

Frequently Asked Questions

How The Lamkin Clinic Approaches Endometriosis

At The Lamkin Clinic, endometriosis is evaluated as a systemic hormonal and inflammatory condition. Treatment targets estrogen metabolism optimization through DIM, sulforaphane, and liver support, anti-inflammatory protocols to reduce pelvic and systemic inflammation, progesterone support to oppose estrogen dominance, gut microbiome restoration to stop estrogen recycling, and environmental toxin reduction. The goal is to change the biological environment that drives endometrial tissue growth, reducing symptoms, improving fertility, and preventing recurrence.
