Chronic Pelvic Pain Warning Signs Show Up in Teenage Years

For many people living with chronic pelvic pain, the road to a diagnosis took years. A new study from McMaster University suggests the first clues may have been there all along, in health care visits during the teenage years. The research, published in The Lancet Regional Health – Americas on October 6, followed people from adolescence into adulthood and found that chronic pelvic pain warning signs are often visible years before a formal diagnosis.

Researchers used linked health records from Ontario, Canada, covering nearly half a million people assigned female at birth who turned 18 between 2008 and 2020. Participants were grouped by whether they had sought care for gynecologic or reproductive problems as teenagers, then matched with peers of the same birth year, income level, and rural or urban setting. The question was whether those teenage health care visits could serve as chronic pelvic pain warning signs long before pain became a lasting condition.

What the study found

By 10 years into adulthood, chronic pelvic pain had been diagnosed in 28 percent of the group that had sought reproductive health care as teenagers, compared with about 15 percent of those who had not. The gap held up even after the researchers accounted for other health problems and overall health care use during the teen years. Across the full follow-up period, the group with teenage reproductive health encounters developed chronic pelvic pain at a rate 41 percent higher than the comparison group. Those figures suggest chronic pelvic pain warning signs show up earlier than most people expect.

The signals were not only about reproductive health. Teenagers who had sought gynecologic or reproductive care were also more likely to experience gastrointestinal problems, mental health conditions, and chronic pain elsewhere in the body. That pattern means chronic pelvic pain warning signs rarely arrive on their own; they tend to show up as part of a broader health picture, according to the study.

Why the signs get missed

Pelvic symptoms in young people are often treated as a normal part of growing up, even when they are severe or persistent. The study stops short of proving that teenage health problems cause chronic pelvic pain in adulthood; it shows the health care system may already be seeing recognizable patterns of vulnerability years before the condition is established. Lead author Shay Freger, a PhD candidate in McMaster's Department of Obstetrics and Gynecology, said the team started with a simple question: whether signs of a path toward chronic pelvic pain were visible years earlier. The answer, the researchers report, was yes. Treating pelvic symptoms as chronic pelvic pain warning signs rather than a normal part of growing up could shorten the wait for care.

Senior author Mathew Leonardi, an associate professor at McMaster, said the notable part is that the warning signs were not limited to reproductive health alone. He suggested that catching chronic pelvic pain warning signs early depends on connecting adolescent menstrual and pelvic health to a broader picture that deserves earlier attention and more integrated care.

What this could change

If the patterns hold, a teenager's visit for a gynecologic or reproductive concern could become a prompt for clinicians to treat chronic pelvic pain warning signs seriously and pay closer attention over the long term. Clinicians could start treating such visits as chronic pelvic pain warning signs that merit follow-up, instead of closing the file once the immediate issue is resolved. That shift matters because the condition affects up to one in four people assigned female at birth and gender diverse people, and it can last for months or years, interfering with school, work, relationships, and mental health.

The researchers drew on population-based health data held by ICES, following individuals from adolescence into adulthood with collaborators at the University of Toronto and McGill University. The work was funded by the Canadian Society for the Advancement of Gynecologic Excellence through an Early Career Investigator Grant.

For young people and their doctors, the takeaway is that chronic pelvic pain warning signs deserve a second look, and acting on them early could shorten the long road many patients face to a diagnosis. An earlier report mapped the two ways bacterial vaginosis comes back, and separate research covered here found that teenagers' daily steps are tied to better mental health.
