Endometriosis is a chronic condition in which tissue similar to the uterine lining grows outside the uterus — on the ovaries, fallopian tubes, bladder, bowel, or elsewhere in the pelvic cavity. Like the uterine lining itself, this tissue responds to the monthly hormonal cycle: it thickens, breaks down, and tries to shed. But with nowhere to go, it causes inflammation, scarring, and persistent pain.

The most common symptoms include severe menstrual cramps, chronic pelvic pain, pain during sex (dyspareunia), painful urination or bowel movements around menstruation, and infertility. The pain is often far beyond what is typically described as "period pain" — many women cannot work or carry out daily activities during their cycle.

There are several reasons why endometriosis is so frequently missed. First, society has long normalised severe period pain, discouraging women from seeking help. Second, its symptoms overlap with other conditions such as irritable bowel syndrome, recurrent UTIs, and ovarian cysts, leading to misdiagnosis. Third, a definitive diagnosis requires laparoscopic surgery, creating a high diagnostic threshold in many healthcare settings.

At THE FIT CLINIC Bangkok, our specialist urogynecology team is experienced in evaluating and managing endometriosis comprehensively — from detailed history-taking and pelvic ultrasound, to personalised treatment planning that may include pain management, hormonal therapy, or surgical referral when needed. You do not have to keep tolerating debilitating pain.

If you have been dismissed with "it's just bad periods," please come and see us. The average woman waits 7–10 years for a diagnosis. With the right specialist, that does not have to be your story.
