Endometriosis · Patient pathway guide

Endometriosis, understood.

Endometriosis affects roughly 1 in 9 Australian women and people assigned female at birth by the age of 44, yet diagnosis is frequently delayed for years. This guide walks you through the science, the tests, the pathway, the treatments, the research, and the support available, so you can navigate the journey with confidence.

Why this guide exists

Pain is not normal simply because it is common. Nobody should wait years to have their pain believed.

02 The Science
What is happening

Tissue in the wrong place.

Endometriosis occurs when tissue similar to the endometrium, the lining of the womb, grows outside the womb. The most common sites are the ovaries, fallopian tubes and the tissue lining the pelvis, but lesions can also be found on the bowel, bladder and, more rarely, further afield.

Hormone sensitive

Like the lining of the womb, endometriosis tissue responds to oestrogen. That is why symptoms often track the menstrual cycle and why hormonal treatments can control the disease.

Why does it happen?

The leading theory is retrograde menstruation, where menstrual fluid flows backwards through the fallopian tubes into the pelvis. Immune, genetic and hormonal factors then determine whose tissue implants and grows.

Three forms

Superficial peritoneal lesions sit on the pelvic lining, endometriomas are cysts within the ovaries (sometimes called chocolate cysts), and deep infiltrating endometriosis invades tissue more than 5 millimetres deep.

Not just a period problem

Symptoms include severe period pain, pelvic pain between periods, pain with sex, painful bowel or bladder function, fatigue, and in some cases difficulty conceiving. Severity of pain does not always match severity of disease.

03 Diagnostic Challenges
Why diagnosis takes time

The long road to a name for your pain.

The average delay from first symptoms to diagnosis is around 6.5 years. Understanding why helps you push the process forward at every appointment.

Symptoms overlap with other conditions

Pelvic pain also features in irritable bowel syndrome, pelvic inflammatory disease, painful bladder syndrome and musculoskeletal pain. Untangling these takes structured history-taking and tests.

No reliable blood test exists yet

There is currently no routine blood test that confirms or excludes endometriosis. Research biomarkers are advancing fast, but none are yet in standard clinical use in Australia.

Imaging has limits

Ultrasound and MRI detect deep disease and endometriomas well in expert hands, but superficial lesions can be invisible on any scan. A normal ultrasound does not exclude endometriosis.

Pain is often normalised

Generations of people have been told severe period pain is normal. It is not. Persisting pain that disrupts your life, school or work deserves investigation.

04 Related Conditions
The relevant group of diseases

Endometriosis sits inside a family of pelvic inflammatory and pain disorders that share symptoms. Many people have more than one. Knowing the group helps you ask the right questions.

Commonly confused

Adenomyosis

Similar tissue grows into the muscle wall of the womb itself. Causes heavy, painful periods and an enlarged womb, and frequently coexists with endometriosis.

Commonly confused

Pelvic inflammatory disease (PID)

Infection of the reproductive organs, often from a sexually transmitted infection. Needs prompt antibiotics to protect fertility.

Commonly confused

Painful bladder syndrome

Also called interstitial cystitis. Bladder pain and urgency without infection, frequently coexisting with endometriosis on the bladder.

Commonly confused

Irritable bowel syndrome (IBS)

Cramping, bloating and altered bowel habit. Endometriosis on the bowel can cause identical symptoms, which is why both are often assessed together.

Commonly confused

Ovarian cysts

Fluid-filled sacs on the ovary, mostly benign and self-resolving. An endometrioma is a specific type of cyst formed by endometriosis.

Commonly confused

Fibroids & PCOS

Fibroids are non-cancerous muscle tumours of the womb causing pressure and heavy bleeding. Polycystic ovary syndrome affects cycles and hormones. Both sit in the same symptom family but need different management.

05 Tests & Diagnosis
Everything currently available

Every test on the table, and what it can and cannot do.

These are the investigations currently used in Australia, from the consultation room to the operating theatre, plus the research tests on the horizon.

Clinical history & pelvic examination

The foundation. A structured history of your symptoms, their timing and impact guides every next step. Examination may reveal tenderness, nodules or fixed pelvic organs.

Role: First step. Cannot confirm the disease on its own.

Transvaginal ultrasound

The first-line imaging test. Detects endometriomas and, in experienced hands, deep infiltrating disease. Superficial lesions usually cannot be seen.

Role: Maps deep disease and cysts. A normal result does not rule out endometriosis.

Pelvic MRI

Adds detail when deep disease, bowel or bladder involvement is suspected, or before complex surgery. Excellent soft-tissue contrast without radiation.

Role: Surgical planning and deep disease mapping.

Diagnostic laparoscopy

The current gold standard. A keyhole camera allows the surgeon to see lesions directly and confirm the diagnosis, often treating at the same time.

Role: Definitive visual diagnosis and staging.

Histopathology of excised tissue

Tissue removed at surgery is examined under the microscope to formally confirm endometriosis. See our pathology topic and glossary for how this report works.

Role: Formal confirmation after surgery.

CA-125 blood test

A tumour marker sometimes raised in endometriosis and ovarian cysts. It is not specific enough to diagnose endometriosis and is mostly used to help assess ovarian masses.

Role: Adjunct only. Not a diagnostic test for endometriosis.
On the horizon

Research biomarkers.

Non-invasive testing is an intense research focus. Recent work published in 2026 includes a four-gene signature panel, salivary microRNA profiling, circulating endometrial cell detection on a microchip platform, EGF as a blood biomarker, and CYFRA 21-1 as a candidate marker. Neutrophil-to-lymphocyte ratio from a routine full blood count is also under study. None of these are yet standard clinical practice in Australia, but they show where diagnosis is heading, and we follow this literature closely.

06 Your Pathway
Step by step

From first appointment to a management plan.

01

See your GP

Start with a structured discussion of your symptoms. Ask about a longer appointment and bring a symptom diary.

02

Investigate

Pelvic examination, ultrasound, and blood tests to exclude other causes. Referral to a gynaecologist follows if needed.

03

Specialist review

A gynaecologist experienced in endometriosis and pelvic pain considers imaging, symptoms and your goals, including fertility.

04

Treatment decisions

Medical therapy, surgery, or both, chosen with you. Pain management and allied health sit alongside.

05

Ongoing management

Endometriosis is a chronic condition. A long-term plan with your GP, specialist and support services keeps you in control.

07 Therapies
Treatment options

The therapies available for people with the disease.

Treatment is personalised. The right combination depends on your symptoms, your disease, and your plans for fertility. Nothing below replaces discussion with your treating team.

Medical

Hormonal therapy

The combined oral contraceptive pill, progestogen-only options, the hormonal IUD (Mirena) and GnRH agonists all work by quietening oestrogen-driven tissue. First-line for symptom control.

Medical

Pain management

Anti-inflammatory and analgesic strategies, planned with your GP, plus specialist pain medicine input for severe or chronic pain.

Surgical

Laparoscopic surgery

Excision (cutting lesions out) or ablation (destroying them) performed by a surgeon experienced in endometriosis. Often combined with diagnosis in the same procedure.

Allied health

Pelvic floor physiotherapy

Specialist physiotherapists treat the muscle tension and pelvic pain that accompany the disease, a cornerstone of multidisciplinary care.

Allied health

Psychology & dietetics

Chronic pain affects mental health, and gut symptoms affect nutrition. Psychologists and dietitians experienced in pelvic pain are part of the standard team.

Fertility

Fertility planning

Endometriosis can affect fertility. Early, structured conversations with your gynaecologist or a fertility specialist preserve options.

08 Movement
Support between episodes

Movement that helps during and between flares.

Gentle, regular movement supports pelvic floor relaxation, circulation and pain modulation. During a flare, rest is the priority; move only as much as feels safe. Stop anything that worsens pain and discuss new exercise with your physiotherapist or doctor.

WalkingThe safest foundation. Ten minutes a day, building slowly, supports circulation and mood without stressing the pelvis.
Swimming & water movementWater supports your weight and takes load off the pelvis, making it one of the best options during painful phases.
Gentle yogaPoses like child's pose, happy baby, cat-cow and supported reclining twists release pelvic and lower-back tension. Avoid intense core compression.
Diaphragmatic breathingSlow belly breathing calms the nervous system and relaxes the pelvic floor. Useful both daily and at the start of a flare.
Pelvic floor relaxationGuided by a pelvic floor physiotherapist, learning to lengthen and release is often more valuable than strengthening.
Pilates (clinical)Low-impact control work with a trained instructor builds core support without aggravating symptoms.
Stretching the hip flexorsLong periods of sitting tighten hips and increase pelvic tension. Gentle daily stretching helps.
Rest, deliberatelyDuring episodes, heat packs, supported lying positions and reduced activity are treatment, not weakness.

11 Common Questions
Frequently asked

Questions patients ask most often.

Can endometriosis be diagnosed with a blood test?

Not yet in routine practice. Research biomarkers including gene signatures, salivary microRNA and EGF are promising and moving quickly, but today the definitive diagnosis is made visually at laparoscopy, confirmed by histopathology of removed tissue.

My ultrasound was normal. Does that mean I don't have it?

No. Superficial endometriosis is frequently invisible on ultrasound, and sometimes on MRI too. A normal scan is useful information, but it does not exclude the disease. Your symptoms and history matter equally.

Does endometriosis always cause infertility?

No. Many people with endometriosis conceive without assistance. The disease can reduce fertility for some, so early, structured conversations with your gynaecologist help you preserve and plan your options.

What should I bring to my first appointment?

A symptom diary covering timing, severity and impact on work or study, a list of treatments already tried, any previous scans or reports, and your questions written down. Ask for a longer appointment if you can.
