Why Does It Take So Long to Get an Endometriosis Diagnosis?

For many women living with endometriosis, the path to diagnosis is not a straightforward one. It often involves years of unanswered questions, multiple visits to various healthcare practitioners, and symptoms that are dismissed, misunderstood, or misattributed.

Delayed diagnosis of endometriosis is widely recognised across healthcare systems globally, with many individuals reporting that it can take between 7 and 11 years from the onset of symptoms to receiving a confirmed diagnosis.

Understanding why these delays happen can shed light on the complexity of the condition, while also highlighting the importance of early recognition, informed participation in healthcare, and self-advocacy.

What Is Endometriosis?

Endometriosis is a chronic condition where tissue similar to the lining of the uterus grows outside the uterus. This tissue can be found on the ovaries, fallopian tubes, bowel, bladder, and other areas within the pelvis and abdomen.

These growths of uterine tissue respond to hormonal changes during the menstrual cycle in a similar way to how the uterus itself responds, which can lead to inflammation, scarring, and a range of symptoms, including:

• Persistent pelvic pain
• Painful periods (dysmenorrhea)
• Heavy or irregular bleeding
• Pain during or after intercourse
• Digestive symptoms such as bloating or nausea
• Fatigue and reduced energy levels

The Average Delay in Diagnosis

One of the most striking aspects of endometriosis is how long it can take to receive a definitive diagnosis. Research and patient reports consistently show that it can take several years—often between 7 to 10 years—for a diagnosis to be confirmed.

This delay is not due to a single issue, but rather a combination of factors:

• Symptoms that are often normalised as ‘just’ period pain
• Overlap with other medical conditions – there are many structures in the pelvis that can cause similar symptoms.
• Limitations in diagnostic tools
• Gaps in awareness and education
• Broader social and cultural influences

For many, the diagnostic journey involves seeing multiple healthcare providers, undergoing various tests, and receiving various alternative diagnoses before endometriosis is finally considered.

Symptoms That Are Often Normalised

A key reason why diagnosing endometriosis is delayed lies in how symptoms are perceived—both by the women experiencing the symptoms and by healthcare providers.

Painful Periods

Severe menstrual pain is one of the most common symptoms of endometriosis. However, it is frequently dismissed as “normal period pain.”

This normalisation can lead to delays in seeking help, as many people are told:

• “Periods are supposed to hurt”
• “It’s just part of being a woman”

In reality, pain that interferes with daily functioning—such as missing school, work, or social activities—is not typical, should be investigated and can often be treated effectively.

Digestive Symptoms

Endometriosis can also present with gastrointestinal symptoms, including:

• Bloating
• Constipation or diarrhoea
• Nausea
• Pain during bowel movements

These symptoms are often mistaken for digestive disorders such as irritable bowel syndrome or Crohn’s disease, which can divert attention away from a pelvic health cause. Part of why this can be confusing for patients and clinicians alike is that endometriosis does in fact often overlap with common gastric conditions. Women with endometriosis are three times more likely to also have irritable bowel syndrome than those without, and gastric symptoms are often significantly limiting.

Fatigue and Brain Fog

Fatigue, low energy, and difficulty concentrating are commonly reported in the context of endometriosis, but complaints are often non-specific. Because these symptoms overlap with many other conditions, they can cause clinicians to become side-tracked and complicate the diagnostic picture.

Recognising endometriosis early is often difficult as clinicians may view symptoms presenting in various body systems in isolation, rather than as part of a broader pattern. Because the symptoms of endometriosis often resembles those of other health conditions, it is also known as  a “mimicking condition”.

Common conditions it may be mistaken for include, amongst others:

• Irritable bowel syndrome (IBS)
• Pelvic inflammatory conditions
• Ovarian cysts
• Chronic pelvic pain disorders
• Urinary tract infections or other conditions

Diagnostic Challenges in Medicine

Even when endometriosis is suspected, confirming the diagnosis is not always straightforward. Unlike many other conditions, there is no single, non-invasive test that can reliably diagnose endometriosis.

• Ultrasound and MRI scans can sometimes detect signs of endometriosis, but not always
• Superficial or smaller lesions may not be visible on imaging
• Normal imaging results do not rule out the condition

This can lead to uncertainty and delays, particularly if symptoms are not taken seriously despite “normal” test results.

Surgical Confirmation

Currently, the most definitive way to diagnose endometriosis is through laparoscopic surgery. This is a minimally invasive surgical procedure, typically done in a day hospital, that allows a specialist to view and potentially remove endometrial-like tissue.

However, surgery comes with its own considerations:

• It is invasive, can be traumatic, and requires recovery time
• It may not be immediately recommended
• Access to suitably trained specialists can be limited
• Surgical intervention may cause additional scarring and adhesions
• Surgical removal of endometrial tissue may not alleviate symptoms

Because of this, many individuals are given a clinical diagnosis of  “suspected” endometriosis for extended periods before receiving final confirmation.

 

What Are the Gaps in Awareness and Education?

Awareness plays a significant role in how quickly endometriosis is recognised and educating patients and clinicians is key to breaking the cycle of diagnostic delay.

Patient Awareness

Many women experiencing symptoms do not realise that what they are experiencing is not typical, particularly if their mother or grandmother had similar symptoms. If someone has always had painful periods, they may assume it is normal. This extends unnecessary suffering and delays help-seeking.

While no single symptom can definitively diagnose endometriosis without surgical confirmation, there are recognisable “red flag” patterns that strongly suggest its presence. These typically involve a combination of severe, function-limiting period pain (pain that interferes with daily activities, work or school), pelvic pain that follows a cyclical pattern, and associated bowel, bladder, or sexual pain. Additional indicators include symptoms that begin in adolescence, progressively worsen over time, or fail to respond to standard treatments such as pain medication or hormonal therapy. Fatigue and cognitive symptoms may also form part of the picture.

Healthcare Training

Perhaps even more important than patients knowing their own symptoms, is raising awareness of endometriosis amongst healthcare providers. A lack of knowledge or awareness of the clinical presentation of endometriosis may result in clinicians:

• Underestimating the severity of symptoms
• Attributing symptoms to more common conditions
• Delaying referral to specialists

With training and education, clinicians can recognise clusters of symptoms and can justify a presumptive diagnosis of endometriosis, allowing earlier intervention and reducing delays caused by waiting for surgical confirmation.

Understanding Social and Cultural Barriers

Beyond medical factors, social and cultural influences also contribute to delayed diagnosis. Amongst others, barriers include period stigma and gender bias in healthcare.

Period Stigma

Menstruation is still a topic that many people, even women, find difficult to discuss openly.

This can lead those experiencing symptoms to be:

• Reluctant to talk about their experience
• Delay help-seeking
• Limit education opportunities about what is normal or abnormal

Periods are a normal part of being a woman, and should become part of open conversations in homes, schools and communities. When conversations about periods are avoided, women and girls do not have the opportunity to self-identify that something more than just ‘normal period pain’ might be going on and the chance for early recognition and treatment could be missed.

Gender Bias in Healthcare

Historically, pain experienced by women has been underestimated or dismissed in healthcare settings. Evidence shows that women are more likely to have their pain dismissed, underestimated, or attributed to psychological causes rather than investigated medically. A recent literature review of multiple population-based studies indicated that over 55% of women report that their pain has been ignored or dismissed by healthcare providers, and nearly a third delay seeking care because they anticipate not being taken seriously . Research further demonstrates that when men and women report the same level of pain, clinicians are more likely to underrate women’s pain and offer psychological support instead of analgesia.

While progress is being made, these biases can still influence the time it takes for women to be accurately diagnosed. These figures are also a call to action for clinicians to consider their own biases and behaviours.

 

Steps that may help you get answers sooner.

Start talking to other women:

Being brave and having discussions with other women about what your period is like, can help you identify whether you are experiencing similar or different symptoms to other people. If it sounds like you might be having more severe or different symptoms to your peers, start a symptom diary to track your symptoms.

Track your symptoms

Keeping a record of symptoms over time can help identify your unique patterns and provide valuable information during medical consultations, helping you give your clinician a comprehensive history.

Consider noting down all the symptoms you think are relevant, but consider these in particular:

• Timing of pain in relation to your cycle
• Severity and impact on daily activities
• Associated symptoms (digestive, fatigue, etc.)

Seek Specialist Care

If your symptoms persist or worsen, it may be helpful to consult a healthcare provider with experience in pelvic pain or endometriosis. This could be a GP specialising in women’s health, a gynaecologist or a uro-gynaecologist.

Specialist input can:

• Improve diagnostic accuracy
• Reduce unnecessary delays
• Provide access to appropriate treatment options

Advocate for your own care

Understanding endometriosis and its symptoms can empower you to recognise when something is not right, and give you the language to communicate with your healthcare provider. Having up to date knowledge also allows you to have informed discussions with your healthcare providers.

It is important that you feel heard and are taken seriously. If you feel that your concerns are being dismissed, try to clearly communicate how your symptoms are affecting your functioning. If after having a conversation with your healthcare provider, you still feel that you are not receiving the care you require, consider seeking a second opinion or asking for further investigation or referral.

Growing awareness and improvements in diagnosis

While there is growing recognition of the challenges associated with diagnosing endometriosis, it is a complex condition with interaction between biology, psychology, and social context. Understanding your condition and the barriers to diagnosis can help you get a diagnosis and treatment sooner.

Efforts to highlight this condition and advocate for care for women who suffer includes

• Increased public awareness campaigns
• Advocacy by patient organisations
• Ongoing research into non-invasive diagnostic methods
• Greater emphasis on multidisciplinary care approaches

These changes are helping to shift the narrative and provide better support for those living with endometriosis.
