Being told your period pain is normal.
Trying birth control after birth control without understanding why the pain keeps returning.
Missing school, work, workouts, dinners, dates, and entire days because of symptoms you’ve learned to plan your life around.
Then, years later, finally hearing a word that explains it:
Endometriosis.
For many women, getting an endometriosis diagnosis isn’t a quick process.
A recent review of international research found an average diagnostic delay of 6.8 years, although the length of delay varied considerably between countries and studies.¹ In Canada, a study of nearly 30,000 women found that those with diagnosed endometriosis reported waiting an average of 5.4 years between symptom onset and diagnosis.²
That’s years of symptoms before having a name for what is happening.
So why is endometriosis still taking so long to diagnose?
The answer isn’t simply that endometriosis is “hard to diagnose.” Research suggests the gap can begin much earlier, with how menstrual pain is understood, how symptoms are communicated, how healthcare professionals respond, and what happens when initial testing looks normal.³
Endometriosis is a chronic condition characterized by endometrial-like tissue growing outside the lining of the uterus. It is estimated to affect up to 10% of women of reproductive age worldwide.⁴
But endometriosis doesn’t look the same in everyone.
Pelvic pain is common, including painful periods, non-menstrual pelvic pain and pain during sex. Endometriosis can also be associated with infertility and bowel or urinary symptoms, while some people may have relatively few symptoms.⁴
That variability is part of what can make recognition difficult.
There isn’t one symptom that automatically means you have endometriosis.
But there are patterns worth paying attention to.
Period pain is common.
That doesn’t mean all period pain should automatically be considered normal.
One of the recurring barriers identified in endometriosis research is the normalization of menstrual pain. A 2023 qualitative systematic review found that difficulty distinguishing pathological symptoms from “normal” menstruation, menstrual stigma, and normalization of period pain all contributed to diagnostic delays.³
This can happen before someone ever enters a doctor’s office.
If you’ve grown up hearing that periods are supposed to hurt, you may assume severe pain is simply something you’re expected to tolerate.
You might reach for a heating pad.
Cancel your plans.
Take pain medication.
Push through work.
And repeat the process the following month.
Research exploring women’s experiences with endometriosis has found that both patients and healthcare professionals can normalize symptoms, contributing to delays in recognizing that further investigation may be warranted.⁵
Common doesn’t always mean normal.
Pain that repeatedly disrupts your ability to function deserves a conversation.
One of the most important things about the endometriosis diagnosis gap is that it can’t be explained entirely by women waiting too long to seek care.
Canadian data illustrate this clearly.
Among women with diagnosed endometriosis, researchers found an average 5.4-year delay from symptom onset to diagnosis. About 3.1 years occurred between symptom onset and first physician consultation, but another **2.3 years occurred after women had already sought medical care.**²
More recent international reviews have similarly identified healthcare-professional and health-system factors as contributors to diagnostic delay.¹˒³˒⁶
A 2025 systematic literature review examining contemporary studies found reported times to diagnosis ranging from 0.3 to 12 years, depending on geography, population and how diagnostic delay was defined. The authors concluded that diagnostic delay remains a persistent problem.⁶
So the question isn’t only:
“Why didn’t she go to the doctor sooner?”
We also need to ask:
“What happened when she did?”
Another challenge is that endometriosis can show up in ways that aren’t immediately recognized as gynecological.
Symptoms may include:
And symptoms can overlap with other conditions.
Research examining diagnostic barriers has specifically identified variable symptom presentations and overlap with other health conditions as factors contributing to delayed diagnosis.³
Someone experiencing bowel symptoms may initially think the problem is gastrointestinal.
Someone with bladder symptoms may focus on the urinary tract.
Someone experiencing painful sex may not realize it could be connected to their periods.
And someone whose primary symptom is infertility may not suspect endometriosis until much later.
That doesn’t mean every one of these symptoms indicates endometriosis.
It means looking at the whole pattern matters.
This is another place where confusion can happen.
You experience significant symptoms.
Your ultrasound comes back normal.
So you assume endometriosis has been ruled out.
Not necessarily.
Ultrasound and MRI can be extremely useful in evaluating suspected endometriosis, particularly when imaging is performed using dedicated protocols and interpreted by professionals experienced in endometriosis imaging. However, diagnostic performance depends on the type and location of disease as well as imaging expertise.⁸
A 2024 review comparing ultrasound and MRI found that both modalities can perform well for pelvic endometriosis when dedicated protocols and experienced clinicians are involved. It also found that routine imaging protocols performed less well than dedicated endometriosis imaging.⁸
Some forms of endometriosis, particularly superficial disease, can also be difficult to detect with imaging.⁴
So a normal scan doesn’t automatically mean that symptoms aren’t real or that the diagnostic conversation needs to end.
Imaging is one part of the picture. Your symptoms and clinical history matter too.
This is another area where the conversation around endometriosis has evolved.
For years, many women heard that laparoscopy was the only way to definitively know whether they had endometriosis.
Surgery remains important and may be appropriate for diagnosis and treatment in certain circumstances. Histologic confirmation of surgically visualized lesions can establish a definitive diagnosis.⁴
But clinical care doesn’t always need to begin with surgery.
A suspected clinical diagnosis can be based on symptoms and supported by physical examination and imaging. Importantly, normal examination or imaging findings do not necessarily exclude endometriosis.⁴
That matters because requiring every patient to undergo surgery before their symptoms are taken seriously creates another potential barrier to care.
The goal isn’t to perform surgery on everyone with painful periods.
It’s to recognize concerning symptom patterns earlier and choose the next diagnostic or treatment step based on the individual.
A diagnosis doesn’t magically make pain disappear.
But having an explanation can still matter enormously.
Qualitative research has found that receiving an endometriosis diagnosis can give women language to describe their symptoms, provide access to potential management strategies, and validate experiences that may have been normalized or dismissed for years.⁵
A more recent mixed-methods study similarly found that patients frequently described dismissal and disbelief by healthcare professionals as contributors to diagnostic delay and considered receiving a diagnosis important for accessing timely, appropriate care.⁹
The years before diagnosis aren’t neutral, either.
Diagnostic delays can mean living longer with pain and other symptoms that affect relationships, work, education, productivity and quality of life.³
A diagnosis isn’t the finish line.
But it can be the beginning of finally understanding what you’re treating.
There probably isn’t one single fix.
Research suggests diagnostic delay occurs at multiple levels: individual, interpersonal, healthcare-professional and health-system.¹˒³
That means improving diagnosis will likely require changes at multiple points along the journey.
We need better menstrual health education so young people understand when pain may deserve medical attention.
We need greater awareness of the different ways endometriosis can present.
We need healthcare professionals who feel equipped to recognize those patterns.
We need access to clinicians and imaging professionals with endometriosis expertise.
And we need to stop treating severe menstrual pain as something women simply have to endure.
Most importantly, women need to feel that saying “this pain is interfering with my life” is enough reason to start investigating why.
You don’t need to diagnose yourself.
But you can document what’s happening.
Tracking when symptoms occur, their severity, whether they change throughout your menstrual cycle, and how they affect your daily activities can make it easier to communicate the full picture to a healthcare professional.
Pay particular attention to patterns such as severe period pain, persistent pelvic pain, pain during sex, cyclical bowel or urinary symptoms, or difficulty conceiving.⁴˒⁷
And don’t minimize the impact.
Instead of only saying, “My periods hurt,” it may be useful to explain what the pain actually prevents you from doing.
I miss work because of my period.
Pain wakes me up at night.
I can’t exercise during the first two days of my cycle.
Sex is painful.
I regularly need to cancel plans because of pelvic pain.
Those details help communicate something a pain score alone sometimes can’t:
how much your symptoms are affecting your life.
The endometriosis diagnosis gap isn’t simply a story about a complicated disease.
It’s also a story about what happens when menstrual pain becomes so normalized that women learn to tolerate symptoms before they learn to question them.
Research still documents substantial delays between symptom onset and diagnosis.¹˒²˒⁶
But a multi-year diagnostic delay doesn’t have to be accepted as an inevitable part of having endometriosis.
Better awareness can help.
Better clinician education can help.
Better diagnostic pathways and access to specialized imaging can help.
And listening when women say something doesn’t feel right can help too.
You shouldn’t need years of pain to prove that your symptoms deserve attention.
