41-Year-Old Zack Van Aarde Diagnosed with Stage 4 Esophageal Cancer After Taking OTC Heartburn Medication for Acid Reflux

When 41-year-old father of two, Zack Van Aarde, began suffering from what he thought was recurring acid reflux, he had no reason to believe it could be anything more serious. A fit and active man from Devon, England, Zack was known for his disciplined lifestyle, running ultramarathons and working out twice daily.

When symptoms of indigestion and heartburn began to interfere with his routine, he sought medical advice and was prescribed over-the-counter heartburn medication for what doctors believed to be acid reflux. But within months, Zack’s condition worsened dramatically — culminating in him collapsing at home after vomiting blood. The subsequent hospital visit revealed a devastating truth: Zack was battling stage four esophageal cancer, an aggressive disease that had already spread beyond its original site.

Zack’s story underscores the dangers of overlooking persistent digestive symptoms and highlights the insidious nature of esophageal cancer, which often goes undiagnosed until it has reached an advanced and life-threatening stage. His experience serves as a powerful reminder of how even the healthiest individuals can be blindsided by a disease that develops quietly and shows few early warning signs.

A Healthy Lifestyle Interrupted by Subtle Symptoms

For years, Zack Van Aarde maintained what most would consider an exemplary lifestyle. As a devoted father and accounts executive, he balanced his professional responsibilities with an intense dedication to physical fitness. Friends and family describe him as a health-conscious individual who followed a nutritious diet, avoided excessive drinking or smoking, and frequently competed in endurance events. Running, in particular, was his passion — not just as a hobby, but as a cornerstone of his identity.

However, what began as mild discomfort after meals gradually evolved into more persistent symptoms. Zack began experiencing frequent heartburn, chest pain after eating, and a sensation of food sticking in his throat — classic signs that many associate with acid reflux. Like millions of others, he turned to common over-the-counter remedies, hoping to relieve the discomfort. His doctor, too, suspected gastroesophageal reflux disease (GERD), a condition caused by stomach acid flowing back into the esophagus.

Initially, the prescribed medication seemed a logical course of action. Proton pump inhibitors (PPIs) and antacids are routinely used to manage heartburn symptoms, and most cases resolve without further concern. Yet for Zack, the relief never came. Instead, his discomfort deepened, accompanied by fatigue and unexplained nausea. Even then, the possibility of cancer seemed remote. “It’s the last thing you think of when you’re young, fit, and living a healthy life,” he reflected.

The turning point came one evening after a run, when Zack suddenly became violently ill. His wife discovered him collapsed on the stairs, vomiting blood — a terrifying moment that forced the family to seek emergency medical attention. At the hospital, doctors initially suspected a bleeding stomach ulcer, but further investigations, including endoscopy and biopsy, revealed a far more serious diagnosis. Zack had a 6-centimeter tumor in his esophagus, and scans confirmed it had already spread to other parts of his body. He was facing stage four esophageal cancer.

Understanding Esophageal Cancer: A Silent and Aggressive Disease

Esophageal cancer is the tenth most common cancer worldwide, yet it remains one of the most lethal. The esophagus — the long muscular tube connecting the throat to the stomach — plays a vital role in digestion by moving food downward through coordinated contractions. Cancer of this organ begins when cells in its lining mutate and grow uncontrollably, forming a tumor. The most common forms are adenocarcinoma, which typically arises in the lower esophagus due to chronic acid exposure, and squamous cell carcinoma, more often linked to smoking and alcohol use.

One of the greatest challenges with esophageal cancer lies in its subtlety. In its early stages, the disease produces few, if any, recognizable symptoms. The esophagus can stretch significantly to accommodate food, allowing tumors to grow undetected for months or even years. By the time swallowing becomes difficult — one of the earliest physical signs — the cancer has often advanced considerably. Other symptoms, such as persistent heartburn, unexplained weight loss, chest discomfort, or vomiting blood, tend to appear only in later stages.

Medical experts note that chronic acid reflux, or GERD, is one of the strongest risk factors for developing esophageal adenocarcinoma. Over time, repeated exposure of the esophageal lining to stomach acid can cause changes known as Barrett’s esophagus, a pre-cancerous condition in which normal cells transform into abnormal, cancer-prone ones. While not everyone with GERD develops cancer, the overlap between symptoms makes early diagnosis difficult. Many, like Zack, are initially treated for reflux before more serious investigations are undertaken.

When Zack’s biopsy confirmed stage four esophageal cancer, the tumor was deemed inoperable. His medical team decided to begin with chemotherapy to try to shrink the growth and control its spread. He now undergoes intensive chemotherapy sessions every two weeks, accompanied by regular blood tests and scans to monitor progress. The treatment is grueling, but Zack remains determined. “It’s been a rollercoaster,” he admitted. “I always kept myself fit and healthy as a young dad. It came as a massive shock, but we’re doing everything we can to give myself the best chance.”

While there is currently no cure for stage four esophageal cancer, modern treatments have improved survival rates and quality of life. Chemotherapy, radiation therapy, and targeted drugs can help slow the disease’s progression, relieve pain, and ease swallowing difficulties. In some cases, immunotherapy — which boosts the body’s own immune system to fight cancer cells — may offer additional hope.

The Emotional Toll and the Importance of Awareness

Beyond the physical battle, Zack’s diagnosis has brought immense emotional challenges. Perhaps the hardest moment came when he had to tell his two young children that he had cancer. “It’s the hardest thing as a parent, telling your kids you’ve got cancer,” he said. “But they’re very resilient and they’re handling it amazingly.” His wife has become his steadfast caregiver, accompanying him to hospital visits and helping manage his treatment schedule.

Zack’s story has resonated deeply with many who believed, as he once did, that leading a healthy lifestyle offered protection from serious illness. While fitness and nutrition undoubtedly play crucial roles in reducing disease risk, cancer can strike even those in peak condition. The underlying causes of esophageal cancer — including chronic acid exposure, genetic predisposition, or environmental factors — often operate silently.

Medical professionals emphasize that persistent or worsening reflux symptoms should not be ignored, particularly if they fail to respond to standard treatments. Difficulty swallowing, chest discomfort unrelated to exercise, unintentional weight loss, or vomiting blood all warrant immediate medical evaluation. Early detection can make a significant difference; when identified before spreading, esophageal cancer can sometimes be treated successfully through surgery and localized therapy.

Zack’s courage in sharing his story has sparked a broader conversation about the need for awareness and vigilance. Too often, digestive discomfort is dismissed as a minor inconvenience or self-treated indefinitely with over-the-counter medications. Yet, as his experience illustrates, what appears to be routine indigestion can sometimes mask a life-threatening condition. By encouraging others to seek proper medical evaluation for persistent symptoms, Zack hopes to help prevent similar tragedies.

Today, he continues his fight with determination and optimism, supported by his family and community. Fundraisers and awareness campaigns have been organized to assist with his treatment and to promote education about esophageal cancer. Despite the daunting prognosis, Zack refuses to let the disease define him. “I’m not giving up,” he said. “There’s still so much to live for.”

Esophageal cancer remains a major global health concern, with approximately 600,000 new cases diagnosed each year. Survival rates vary depending on the stage at diagnosis, but early intervention remains the strongest predictor of positive outcomes. Screening initiatives, especially for those with chronic acid reflux or Barrett’s esophagus, are essential in identifying precancerous changes before they develop into full-blown cancer.

Zack’s journey is a poignant example of how quickly life can change — and how crucial it is to listen to one’s body. His resilience, despite the odds, continues to inspire others facing similar battles. For now, he is focusing on treatment, spending time with his family, and maintaining hope in the face of uncertainty. Though his path forward is fraught with challenges, his message to others is clear: never take persistent symptoms for granted, and never assume that good health guarantees immunity from serious illness.

As research advances and new therapies emerge, the outlook for esophageal cancer patients continues to improve. Awareness, early detection, and lifestyle vigilance remain key defenses. Zack’s ordeal, while deeply personal, serves as a public reminder of the fine line between everyday ailments and the early signs of a deadly disease — a reminder that could ultimately save lives.
