Endometriosis

Average time to diagnosis: 7 to 10 years. Average specialists seen before answers: 5 or more. The delay is not your fault — it is the system.

About Endometriosis

What we mean when we say Endometriosis.

Endometriosis is a chronic inflammatory disease in which tissue resembling the endometrial lining grows outside the uterus, causing pain, organ dysfunction, and infertility. It affects an estimated 190 million women and girls of reproductive age worldwide.

Despite its prevalence, endometriosis is among the most under-diagnosed conditions in medicine. Patients commonly report decades of pain dismissed as 'normal' menstruation. The diagnosis is definitively made via laparoscopy, but many patients can be effectively staged and managed based on imaging and clinical evaluation by an experienced specialist.

Endometriosis rarely exists alone. Many patients also have adenomyosis, interstitial cystitis, irritable bowel syndrome, mast cell activation, hypermobility, and chronic fatigue — a constellation that no single specialty owns.

Prevalence

Approximately 190 million women and girls of reproductive age worldwide (WHO, 2023). Roughly 10% of the reproductive-age female population.

Endometriosis comorbidity literature

Endometriosis is missed and mismanaged for reasons that have less to do with the disease and more to do with how pelvic pain is evaluated. The diagnostic delay — 7 to 10 years on average — reflects systemic patterns in medical training and practice, not the difficulty of recognizing the condition.

  1. 01
    Severe menstrual pain has been culturally and clinically normalized. Many providers still teach patients that significant dysmenorrhea is expected, leading to years of dismissal before the workup begins.
  2. 02
    Imaging frequently appears normal even in advanced endometriosis. Transvaginal ultrasound and standard pelvic MRI miss the majority of superficial and bowel-surface implants, producing false reassurance.
  3. 03
    Excision versus ablation surgery produces meaningfully different outcomes, but most patients are never told this and are routed to whichever technique their surgeon performs. Recurrence and pain trajectory diverge significantly between the two.
  4. 04
    The comorbid pelvic-pain cluster — adenomyosis, interstitial cystitis, pelvic floor dysfunction, MCAS, hEDS — is rarely synthesized by a single clinician. Patients accumulate diagnoses one at a time over years instead of having the picture integrated.
How we approach it

The Ternary Health approach to Endometriosis.

01

Map the full pelvic-pain differential including endometriosis stage and location estimation, adenomyosis evaluation, interstitial cystitis screening, pelvic floor involvement, and IBS overlap — rather than treating endometriosis as the sole hypothesis.

02

Evaluate the surgical decision specifically: excision versus ablation, surgeon experience and case volume, the difference between general gynecologists and high-volume excision specialists, and the timing of surgery relative to fertility and pain goals.

03

Audit hormonal management — combined oral contraceptives, progestin-only options, GnRH agonists and antagonists, and the trade-offs each carries — against the patient's specific symptom pattern, fertility goals, and side-effect tolerance.

04

Screen for the multi-system comorbidities frequently coexistent with endometriosis: mast cell activation, hypermobility, autonomic dysfunction, and central sensitization. These often explain incomplete response to endometriosis-directed treatment alone.

Signals we look for

The Ternary Signal Library for Endometriosis.

Our Signal Library for Endometriosis codifies the specific patterns that matter — imaging findings, hormonal and inflammatory markers, surgical history, and pelvic-cluster comorbidities. Your case is mapped against these signals; each present signal is identified and prioritized for your presentation.

Imaging & Anatomic Mapping
  • Transvaginal ultrasound — endometrioma identification and characterization
  • Pelvic MRI with endometriosis-specific protocol — deep infiltrating disease
  • Adenomyosis evaluation — uterine wall, junctional zone, T2-weighted patterns
  • Bowel and bladder involvement — surface implants and infiltration depth
  • Anatomic distortion and adhesion mapping
Hormonal & Inflammatory Markers
  • CA-125 — limited utility, but pattern in context
  • Hormonal panel — estradiol, progesterone, FSH, LH, AMH
  • Inflammatory markers — CRP, ESR, cytokine patterns where measured
  • Vitamin D, ferritin — frequently low in endometriosis cohorts
  • Thyroid function — overlap with reproductive symptoms
Surgical & Pathologic History
  • Prior surgeries — excision vs. ablation classification
  • Pathology reports — confirmed lesions, staging, locations
  • Recurrence pattern and timeline
  • Surgeon experience and case volume documentation
  • Pelvic floor and adhesion considerations from prior operative reports
Pelvic-Cluster Comorbidity Patterns
  • Interstitial cystitis screening — symptom pattern and prior workup
  • Adenomyosis indicators — heavy bleeding, dysmenorrhea, ultrasound findings
  • Pelvic floor dysfunction — manual evaluation findings, voiding patterns
  • Mast cell involvement — multi-system mediator pattern
  • Hypermobility — Beighton score, connective tissue findings
The nine-stage workflow, applied

How a Endometriosis case moves through our workflow.

Our nine-stage workflow is the same for every engagement. What changes per condition is the content at each stage — the records we pull, the signals we apply, the specialists we map, the pathways we evaluate. Below, how your case specifically would move through each stage.

Stage 01 · 0–2
Qualification
Fit screen confirms diagnosed or strongly suspected endometriosis, access to imaging and operative reports if available, and current treatment status. Surgical history and fertility goals matter for case prioritization.
Stage 02 · 3–7
Intake & data aggregation
Records pull emphasizes pelvic imaging, operative and pathology reports, hormonal panels, and prior pain medication and hormonal therapy history. Symptom and cycle history built as a structured timeline.
Stage 03 · 7–10
Case structuring
Case schema populated. Comorbid pelvic-cluster screen performed in parallel — IC/BPS, adenomyosis, pelvic floor, IBS. Surgical history reconstructed with attention to excision-vs-ablation technique.
Stage 04 · 10–14
Signal analysis
The Ternary Signal Library for endometriosis is applied. Typical case activates 12–18 signals across imaging, hormonal, surgical, and comorbidity domains. Each signal evaluated for your specific presentation.
Stage 05 · 14–19
Evidence retrieval
Literature scan emphasizes excision-vs-ablation outcomes data, deep infiltrating endometriosis surgical series, hormonal management comparative evidence, and the endometriosis-comorbidity literature on IC, adenomyosis, MCAS, and hEDS overlap. Condition-specific Evidence Matrix refreshed.
Stage 06 · 19–24
Pathway mapping
Pathway map built across high-volume excision surgeons, reproductive endocrinology (where fertility is in scope), pelvic floor physical therapy, urology for IC overlap, and pain management. Specialists mapped from our Specialist Graph.
Stage 07 · 24–28
Synthesis & plan construction
Every option weighed against the three questions (Evidence × Personalization × Action), then prioritized and sequenced. Dependencies encoded as a directed graph — surgical timing informs fertility planning, which informs hormonal strategy, which informs pain management trajectory.
Stage 08 · 28–32
Delivery & calibration
Findings call with attention to surgical decision support, fertility timing, and comorbidity management priorities. Your priorities and constraints update the plan before finalization.
Stage 09 · 32–62
Execution support
30 days of asynchronous follow-up through the typical endometriosis consultation sequence — surgical consults, REI if indicated, urology for IC overlap, and pelvic floor PT. Outcomes captured into the Ledger.

Patients with Endometriosis frequently present with one or more of the following. Ternary reports evaluate the full picture rather than the condition in isolation.

Common questions — Endometriosis

What prospective Endometriosis clients ask most.

I've had laparoscopy and was told I have endometriosis, but the pain is back. What now?
This is the most common reason people apply. The answer usually depends on what technique was used. Ablation has higher recurrence rates than excision, and many patients who report 'recurrence' actually had incomplete initial excision rather than new disease. We review the operative report carefully and map what should have been removed versus what was.
Does it matter which surgeon I choose for excision?
Enormously. Excision of deep infiltrating endometriosis is a high-skill, high-volume procedure. The outcomes data show meaningful differences between high-volume excision specialists and general gynecologists offering laparoscopy. Surgeon selection is one of the highest-leverage decisions in this condition, and we treat it as such.
Do I need a confirmed diagnosis before applying?
A laparoscopic or imaging-suggested diagnosis is preferred. If you have a clinical picture consistent with endometriosis but no workup yet, we can frame the differential and the evaluation pathway. We do not make diagnoses.
How does fertility planning factor into the case review?
Heavily, when it's in scope. Surgical timing, ovarian reserve assessment (AMH, antral follicle count), the trade-off between surgical excision and IVF prioritization, and hormonal management compatibility with fertility goals are all built into the plan when fertility is on the table.
What about the other pelvic conditions — IC, adenomyosis, MCAS?
Screened and incorporated in every case. The single most common reason endometriosis-directed treatment underperforms is unrecognized comorbid pelvic disease. The Ternary report integrates them rather than treating endometriosis in isolation.
