Endometriosis: New ACOG Guidance May Help Shorten the Long Road to Diagnosis

For years, many patients with endometriosis have faced a frustrating pattern: severe symptoms, repeated misdiagnoses, and a long wait for answers. Now, updated guidance from the American College of Obstetricians and Gynecologists (ACOG) could help shorten that path by encouraging earlier, less invasive diagnosis and faster access to treatment. ACOG announced its new clinical guidance on Feb 2026, describing it as an effort to shorten time to diagnosis and improve access to care.

Endometriosis is a chronic disease in which tissue similar to the lining of the uterus grows outside the uterus, often causing pelvic pain, painful menstruation, heavy bleeding, infertility, bloating, and nausea. The World Health Organization estimates that it affects about 10% of reproductive-age women worldwide—around 190 million people.

Why Diagnosis Has Taken So Long

Despite how common it is, endometriosis has long been under-recognized. Many patients are told their symptoms are normal, while others are initially diagnosed with gastrointestinal, urinary, or other gynecologic disorders instead. The result is a major delay in care: recent reporting on the ACOG update notes that diagnosis often takes an average of 4 to 11 years after symptoms begin.

A major reason is the historical reliance on laparoscopy as the diagnostic gold standard. Although laparoscopy can confirm disease, it is still an invasive surgical procedure that may involve long waits, higher costs, and hesitation from patients who do not want surgery. That model has made diagnosis slower and harder to access, especially when symptoms are already affecting quality of life.

What the New Guidance Recommends

The most important shift in the updated guidance is that ACOG now supports a stronger clinical diagnosis approach. In other words, clinicians do not always need to wait for surgery before recognizing probable endometriosis and starting treatment. According to ACOG, doctors should suspect endometriosis in adolescents or adults with symptoms such as persistent pelvic pain, dysmenorrhea, pain during sex, pain with urination, pain with bowel movements, or infertility accompanied by at least one of these symptoms.

For evaluation, the guidance recommends starting with transvaginal ultrasound or abdominal ultrasound, depending on the patient and clinical context. MRI can then be used when more detailed imaging is needed. Importantly, the decision to perform laparoscopy should be made through discussion between clinician and patient, and treatment may begin even without surgical confirmation.

That could be a meaningful change for patients who have spent years waiting for validation. Earlier diagnosis may allow first-line treatment—such as hormonal therapy including birth control pills—to begin sooner, potentially reducing symptom burden and limiting disease progression.

A Broader Push for More Equitable Care

The updated guidance also highlights barriers that go beyond clinical testing. Limited awareness of symptoms, along with racial bias and gender-identity-related barriers, can delay diagnosis and treatment. ACOG’s updated recommendations place greater emphasis on equitable care and on recognizing that endometriosis has historically been under-recognized in marginalized populations.

Just as importantly, the guidance stresses shared decision-making. That reflects a growing recognition that endometriosis does not look the same in every patient, and that pelvic pain and menstrual symptoms should not be dismissed or normalized. By moving toward earlier clinical recognition and more patient-centered evaluation, ACOG’s new guidance signals a wider shift: endometriosis should be taken seriously, assessed earlier, and managed before years of suffering.
