Millions Face Years-Long Wait for Endometriosis Diagnosis Despite Debilitating Symptoms

The Hidden Epidemic Affecting One in Ten Women

Each March, as Endometriosis Awareness Month arrives, millions of women worldwide are reminded of a staggering medical reality: for millions of women, the pain is real, but the diagnosis can take years. March is Endometriosis Awareness Month, a time dedicated to raising awareness about a chronic and often misunderstood condition that affects more than 1 in 10 women of reproductive age. Endometriosis may affect more than 11% of American women between 15 and 44. Yet despite its prevalence, the average time to diagnose the condition was 6.6 years , with some cases taking decades to identify.

Endometriosis (en-doe-me-tree-O-sis) is a condition where tissue similar to the lining of the uterus grows in other places in the body. Endometriosis happens when tissue similar to the lining of the uterus begins growing outside the uterus — often on other organs in the pelvic area. For many women, that can mean severe pelvic pain, painful bowel movements or urination, pain during or after sexual intercourse, extreme fatigue and, in some cases, infertility.

The condition's impact extends far beyond physical discomfort. Many people with endometriosis experience anxiety and/or depression due to their symptoms. People with endometriosis face a significantly higher risk of depression, anxiety, and eating disorders. A 2023 Yale study confirmed a genetic correlation between endometriosis and these mental health disorders, highlighting that they're likely not just a product of endometriosis, but a component and symptom of it.

The Diagnosis Dilemma

The path to an endometriosis diagnosis remains frustratingly complex. However, the only way to know for sure if an individual has endometriosis is through laparoscopic surgery. There's currently no single blood test or simple imaging method to detect all forms of endometriosis. Confirming endometriosis is most reliable through direct visualization and biopsy using a diagnostic laparoscopy.

Multiple factors contribute to diagnostic delays. Historically, severe menstrual pain has been a normalized, and ultimately downplayed, part of womanhood, delaying appropriate medical attention. Endometriosis symptoms almost always bear similarities to those of other reproductive and abdominal conditions, such as IBS, ovarian cysts, or bladder issues, causing frequent misdiagnosis to occur. The disease is often misdiagnosed or missed altogether. Black and Hispanic individuals also continue to be diagnosed at far lower rates than their White counterparts because of systemic inequities in care.

Recent research reveals troubling patterns in the diagnostic journey. The average diagnostic delay reported across studies was 6.8 years (range 1.5–11.4 years) , while the average diagnostic delay was 10 years for endometriosis and 11 years for adenomyosis. This was reflected by the number of doctors seen, which averaged 2.0 for adolescents (19) and 4.1 for adults (range 2.5-7) before receiving a proper diagnosis.

Breaking Down Barriers to Better Care

Healthcare systems worldwide are beginning to recognize the urgency of addressing diagnostic delays. "Unfortunately, concerns about menstrual pain are often dismissed, even in clinical settings," State Health Commissioner Dr. James McDonald said. "We need to continue to raise awareness about this condition and its serious, lifelong impacts. Those who think they may have endometriosis should be taken seriously in the exam room and treated with compassionate care."

Treatment approaches have evolved, though challenges remain. There is no cure for endometriosis, but treatments are available for the symptoms and problems it causes. In 2018, the U.S. Food and Drug Administration (FDA) approved elagolix (Orilissa®) for the treatment of pain associated with endometriosis—the first and only pill specifically approved for endometriosis pain-relief. Thankfully, there are numerous treatments and strategies for managing endometriosis, including medication, excision surgery, lifestyle modifications, physical therapy, and holistic approaches. These management practices can significantly enhance the quality of life.

Emerging diagnostic tools offer hope for faster identification. There is hope, however, for a less invasive option developed by Australian researchers that screens for protein biomarkers of endometriosis in the blood. New and emerging diagnostic tests aimed at identifying endometriosis earlier include simple symptom checklists, blood tests, and increasingly self-tests using saliva or menstrual blood.

The Path Forward

As awareness grows, the medical community faces mounting pressure to transform endometriosis care.
