Teen's endometriosis battle: Doctors dismissed her pain as 'too young' to suffer

Grace was thirteen when the pain became unbearable. Every month, around the time of her period, her parents would have to carry her to the car—she couldn't walk—and drive her to the hospital. She would wait hours in A&E, only to be sent home with stronger painkillers and no answers. This happened again and again. The fourteen-year-old from Yorkshire describes the sensation as heated barbed wire wrapped around her abdomen, as if her organs were being torn apart. She became bedbound during her cycle. When the pills she had at home ran out, she needed morphine.

For years, doctors offered her a rotating list of explanations that never quite fit. Irritable bowel syndrome. A cyst. Anxiety. Just a particularly bad period. Grace knew something was fundamentally wrong, but when she asked if it could be endometriosis—a condition where tissue similar to the womb lining grows outside where it belongs, causing lesions and scarring—she was told repeatedly that she was too young. Adolescents don't get endometriosis. That's something older women deal with. Her requests for further investigation were dismissed. She felt, as she puts it, like she was being seen as a dramatic girl trying to avoid school.

The frustration deepened when even a specialist she saw privately wouldn't believe her. "If a specialist won't listen to me, who will?" she asked. It wasn't until her family pushed for a second private opinion that she finally received a diagnosis. By then, she had spent years in severe pain, dependent on opioids, missing school and social activities during a crucial time of her life. The worry about that dependency haunts her. "It's scary," she says, "because I don't want to have to rely on them for the rest of my life."

What makes Grace's case particularly troubling is how preventable the delay was. Endometriosis affects roughly one in ten women and can develop once periods begin—a fact that contradicts the widespread medical assumption that it's an older woman's disease. Dr. Gail Busby, a paediatric gynaecologist, sees adolescents with the condition regularly at her clinics, including girls younger than Grace. The real marker of abnormality, Busby explains, isn't just painful periods—nearly eighty percent of adolescents experience those. It's when the pain is so severe that a girl misses school every month, skips PE, stays home while friends go out. "When you're in bed and your best friend is a hot water bottle," Busby says, "that's not normal."

The condition carries consequences that extend far beyond the immediate agony. Endometriosis can damage reproductive organs, and Grace has already been warned that her fertility may be compromised. She's been told she may not be able to have children after age thirty—a prognosis that has created a different kind of pressure. At fourteen, she feels rushed: she has to have children within the next fifteen years or risk losing that option entirely. The psychological toll compounds the physical one. Girls like Grace are more likely to develop anxiety or depression when chronic pain disrupts the educational, emotional, and social development that adolescence is supposed to provide.

Grace's case is not unusual, according to Dr. Busby, and it reflects a broader failure in medical education and practice. The charity Endometriosis UK notes that diagnosis typically takes an average of nine years in older women—and the delay is often worse in teenagers, partly because the condition frequently doesn't show up on ultrasound scans in early stages. New diagnostic tests are being developed that may help identify it sooner, but they're not yet standard. The charity's spokesperson argues that the government, NHS, and health practitioners need to dramatically improve menstrual health education for young people if they want to prevent the next generation from having their futures derailed by undiagnosed, untreated pain.

Grace recently underwent keyhole surgery to remove her endometriosis and has been advised to take hormonal contraceptives to slow tissue growth and reduce pain. She hopes the procedure will bring relief, at least temporarily. But her real motivation for speaking publicly is different. She wants other teenagers to know that their pain is real, that they know their bodies better than anyone else, and that they shouldn't be made to feel like they're imagining things. "I felt I was going crazy," she says. "That it was all in my head. But actually, you know your body best and your pain is real."
