For many patients with endometriosis, the journey to diagnosis is not a straight line. Instead, it is often marked by years of unanswered questions, dismissed symptoms, and trial-and-error treatments. Despite growing awareness, delayed diagnosis remains one of the most persistent—and frustrating—features of endometriosis care.

One reason diagnosis is so challenging is that endometriosis cannot be reliably diagnosed—or excluded—by imaging alone, yet much of modern medicine is oriented around conditions that can be visualized.  Ultrasound and MRI can identify certain forms of disease, particularly deep infiltrating endometriosis, but they frequently miss superficial or peritoneal disease. As a result, patients are sometimes reassured that everything is “normal,” even when symptoms persist.

Another contributor is the normalization of pelvic pain. Many patients are told that painful periods are expected or that symptoms will improve with time or hormonal treatment. While medical therapy can be helpful for some, persistent or worsening symptoms should prompt reconsideration of the underlying diagnosis rather than continued symptom suppression alone.

Endometriosis evaluation works best when physicians actively consider the disease, combining patient symptoms, risk factors, physical exam, and imaging—not relying on imaging alone. Providers with expertise in endometriosis are more familiar with the limitations of testing and the wide range of ways the disease can present. Earlier referral to a specialty practice can significantly shorten the diagnostic timeline, particularly for patients with longstanding pain with periods or infertility accompanied by pain symptoms.

The long path to diagnosis is not a failure of patients—it reflects a disease that is still widely misunderstood by the medical community. By taking symptoms seriously and reassessing when treatments are not working, that path can become clearer and far less prolonged. At Pacific Endometriosis and Pelvic Surgery, meaningful answers often begin with listening paired with a deep understanding of the complexity of endometriosis.
