She was 26 years old when she finally got the diagnosis. She had been in pain since she was 14. In the years between, she saw three pediatricians, a gastroenterologist, and four obstetrician-gynecologists. She was told her pain was normal. She was told to take ibuprofen. She was told it was stress.
She did not have a rare disease. She had endometriosis — a condition affecting roughly 1 in 10 women worldwide. It is not obscure. It is not subtle. And yet the average time from first symptoms to confirmed diagnosis has been, for the past decade, approximately eight years.
I have been practicing obstetrics and gynecology for more than 50 years. I have seen this delay happen. I have also seen us — as a field — look away from it.
What Endometriosis Is
Endometriosis is a condition where tissue similar to the lining of the uterus grows outside the uterus — on the ovaries, fallopian tubes, bowel, bladder, and sometimes further. It causes chronic pelvic pain, painful periods, pain during sex, and in many cases, infertility.
The symptoms are not vague. Chronic pelvic pain, dysmenorrhea, and dyspareunia are present in more than 80% of women with the condition. These are not silent findings. They are the reason women come to our offices.
And yet a New Zealand study found that patients who reported being dismissed by a clinician waited an average of 9 years for a diagnosis. Those who were not dismissed waited 4.6 years. The gap is not biology. It is clinical behavior.
Why the Delay Happens
The most common explanation is that period pain is normalized — by patients, by families, and by physicians. Women are told that painful periods are part of being a woman. Many believe it. Many of us have reinforced it.
There is also a diagnostic problem. The gold standard for diagnosing endometriosis is still laparoscopy — a surgical procedure. Without visible proof, the diagnosis lives in a clinical limbo. Physicians are reluctant to refer for surgery without clear imaging findings. Most endometriosis does not show on routine ultrasound. So the loop closes on itself: no proof without surgery, no surgery without proof, and the patient continues waiting.
The result is measurable suffering. Endometriosis leads to an average of 19 missed work days per year. It is among the leading causes of years lived with disability in women of reproductive age. These are not estimates. These are documented, published findings.
What Patients Are Doing Instead
They are going to Reddit at 2 a.m. They are buying books subtitled ‘what your doctor won’t tell you.’ They are spending money on supplements and elimination diets and wellness programs because someone on social media told them that medicine had failed them — and in this case, medicine had.
The r/endometriosis community has hundreds of thousands of members. The posts follow a pattern that any clinician should recognize: years of symptoms, multiple physicians, repeated reassurance that nothing is wrong, and finally — sometimes after a decade — a diagnosis that changes everything they thought about their own body.
This is not a failure of patient education. It is a failure of clinical attentiveness.
A Tool for the Conversation
I built a symptom screener — free, evidence-based, aligned with the 2026 ACOG Clinical Practice Guideline on endometriosis — to help patients organize their symptoms before a clinical visit and help clinicians see the pattern more clearly. It takes about five minutes. It produces both a patient-facing summary and a clinical differential that you can use in practice.
