Katja Snoeijs, an Everton forward, had her life turned upside down when she experienced severe "stabbing" pains during a match against West Ham last season. This painful moment marked the beginning of her journey toward understanding and addressing her health struggles with endometriosis, a condition that affects many women yet often goes undiagnosed for years. Snoeijs’ story sheds light on the challenges female athletes face and highlights the importance of awareness regarding this condition.
Recognizing the Symptoms
Snoeijs first realized something was wrong when the intense cramps around her abdomen and back made it nearly impossible to continue playing. "The cramps around my womb and my belly were just horrible. Even the back pain made it hard to stand up straight, let alone sprint or run," she recalled. This emotional moment on the pitch, where most players would push through minor injuries, was different for her; it was a critical turning point in identifying her underlying health issues.
After seeking medical attention, Snoeijs faced a challenging path similar to that of many women with endometriosis. Despite her efforts to get a diagnosis after that game, she initially received no clear answers. Determined to find out what was wrong, she consulted Everton's club doctor, leading to the recommendation for keyhole surgery— the only definitive way to diagnose endometriosis. “Until I got the diagnosis, it was really challenging because I felt I was constantly doubting myself,” she explained. The lack of recognition for her symptoms left her feeling isolated and frustrated, but the surgery ultimately provided clarity and hope for her future.
The Ongoing Battle and Awareness
While surgery can provide relief and a diagnosis, endometriosis remains a chronic condition with no cure, characterized by unpredictable symptoms. Snoeijs shared her experiences of fluctuating pain levels during her menstrual cycle: "Sometimes my period passes without symptoms, but at other times, the pain feels like someone is continuously stabbing me in the stomach." Other athletes have echoed similar sentiments, highlighting the physical and emotional toll that endometriosis can take. For instance, England captain Leah Williamson revealed her fears about potentially missing the Euro 2022 campaign due to the debilitating effects of her condition.

Emma Cox, the chief executive of Endometriosis UK, noted that Snoeijs' experience of enduring pain is all too common among female athletes. “We see it in a lot of women because they’re led to believe that it’s normal—nobody discusses the level of pain,” she stated. Many athletes tend to push through discomfort, often doubting their own experiences. Snoeijs expressed this struggle: "In your head, you’re still doubting yourself thinking like: ‘Oh, maybe I could have played through this.’”
Spreading Awareness and Moving Forward
Having returned to training post-surgery, Snoeijs is now passionate about raising awareness regarding endometriosis, particularly within women's sports. “The reality is it affects one in 10 women. So probably in every WSL team, there is a player struggling with similar symptoms,” she shared. Her message emphasizes the importance of trusting oneself and seeking help when something feels wrong. “I’ve learned through this journey that sometimes it is better to protect yourself,” she added.
Snoeijs remains steadfast in her belief that her diagnosis does not define her. “Yes, I have endometriosis, but I’m also more than my condition,” she asserted. Her determination to succeed in professional sports while managing her health showcases resilience and offers hope to others facing similar challenges. March is recognized as Endometriosis Awareness Month in the UK, making it an opportune time for individuals like Snoeijs to advocate for better understanding and support for those affected by this condition.
