Pop star Ella Henderson’s voice has filled arenas across the UK and beyond, but her latest message isn’t a chart-topper—it’s a powerful, deeply personal disclosure that’s resonating with millions. In a recent Instagram video, the 29-year-old singer revealed she was diagnosed with endometriosis earlier this year, after struggling for years with intense stomach bloating, pelvic pain, and emotional distress.What Henderson didn’t expect was how long and difficult her journey to a diagnosis would be—and how sharing it would help shine a spotlight on one of the most misunderstood chronic conditions affecting people assigned female at birth.“For the last few years, it's been a bit of a rollercoaster, to say the least,” Henderson confessed in her video. While fans watched her perform and thrive in the spotlight, behind the scenes she was quietly battling unrelenting symptoms. She describes how she was plagued by stomach bloating, pelvic discomfort, and deep emotional turmoil—made worse by not being taken seriously.“I thought at one point that this was just all in my head,” she said. “I wasn’t really believed.”For many with endometriosis, that experience is painfully familiar.After undergoing a laparoscopy—a minimally invasive surgical procedure used to diagnose and sometimes treat endometriosis—Henderson received confirmation that she wasn’t imagining anything. The procedure uncovered severe endometrial growths and scarring behind her uterus, affecting her bladder and bowel.“Although the diagnosis was devastating, it was also validating,” she explained. “I could finally take control of my body.”That moment of clarity often takes years for patients. According to Endometriosis UK, it takes an average of eight to nine years from symptom onset to diagnosis in the UK. Many people, like Henderson, suffer in silence, cycling through misdiagnoses while trying to manage what often becomes debilitating chronic pain.What makes it harder is that some people have severe symptoms, while others may be asymptomatic. The severity of symptoms doesn't always align with the extent of the disease. Henderson spoke openly about how her physical struggles snowballed into mental health challenges. Living with constant pain, while being dismissed or misdiagnosed, took a toll.“Not being believed led to periods of depression, isolation, and anxiety,” she said. “If health practitioners had recognised my symptoms sooner, all that might have been spared.”This psychological burden is common among endometriosis patients. According to studies, mental health disorders, including anxiety and depression, occur at higher rates in those living with chronic pain from endometriosis. And yet, mental health support is rarely part of routine treatment plans.Though there’s no cure for endometriosis, Henderson’s surgery helped ease her symptoms significantly. She’s now committed to long-term management, including lifestyle adjustments, possible hormonal therapy, and regular medical monitoring.She’s also using her platform to advocate for awareness. In partnership with Endometriosis UK, Henderson is promoting tools to help others recognize symptoms early. One tool allows users to check symptoms in under a minute and generate a personalized letter for their healthcare provider—a small step that could dramatically shorten the diagnostic timeline for many.Emma Cox, CEO of Endometriosis UK, praised Henderson’s courage in going public:“Ella’s willingness to share her story will no doubt help others in their diagnosis journey,” she said. “Highlighting the significant and detrimental impact the condition can have on all aspects of someone’s life.”And she’s right, endometriosis affects 1 in 10 women and people assigned female at birth—that’s over 1.5 million in the UK alone. Yet, stigma, misinformation, and delays in care are still the norm.What is Endometriosis?Endometriosis is a medical condition in which tissue that resembles the lining of the uterus grows outside the womb. These renegade cells are able to adhere to organs such as the ovaries, bladder, bowel, or even below the pelvis, responding to hormonal shifts similarly to uterine tissue—thickening, deteriorating, and bleeding with every menstrual cycle but unlike during a normal period, this tissue has no place to go, leading to inflammation, scarring, organ damage, and extreme discomfort. Symptoms are diverse but frequently include:Heavy or painful periodsPelvic pain that is chronicDiscomfort during intercourseBowel and urinary discomfortInability to conceiveSevere bloating, also referred to as "endo belly"Excessive fatigueTypes of EndometriosisThere are four primary forms of endometriosis:Peritoneal (superficial): On the thin layer of the pelvis.Ovarian (endometriomas): Ovarian cysts packed with old blood.Deep endometriosis: Deep tissue like in the bowel or bladder.Extra-pelvic endometriosis: Uncommon instances where lesions occur in the lungs or surgical incisions.Associated conditions such as adenomyosis, in which endometrial tissue invades the uterine wall, tend to exist concurrently with endometriosis, further complicating diagnosis and treatment.While treatment involves hormonal therapies, analgesics, physical therapy, and surgery in some cases, there is no silver bullet, and most patients have to try a series of methods before experiencing relief.And though Ella's celebrity generates publicity, the struggle for recognition, treatment, and compassion is that of every woman, girl, and individual touched by this frequently hidden disease.If you or someone you know is experiencing symptoms of endometriosis, don’t wait. Speak with a healthcare professional and explore resources like Endometriosis UK or the Endometriosis Foundation of America because the sooner we stop doubting women’s pain, the sooner we start healing.
