The Definitive Cause of Ozzy Osbourne's Passing

The speculation that followed Ozzy Osbourne’s death was quickly resolved by official reports. The legendary rocker did not succumb to his long-running battle with Parkinson’s disease, nor did he pass away directly from complications of his spinal injuries. Instead, his death was a result of a sudden and catastrophic cardiovascular event.

Cardiac Arrest and Coronary Artery Disease

The official cause of death listed on Ozzy Osbourne’s death certificate was cardiac arrest, with the underlying condition being severe coronary artery disease (CAD). This is a condition where the major blood vessels that supply the heart become damaged or diseased, often due to a buildup of plaque, which narrows the arteries and reduces blood flow to the heart muscle. In Ozzy’s case, the heart attack was a final, fatal event that his body could not overcome.

While the heavy metal icon’s decades of drug and alcohol abuse were often cited as a likely cause for future health issues, his family and medical team had consistently worked to manage his health in his later years. However, the cumulative stress on his system, exacerbated by the chronic pain and immobility from other conditions, likely contributed to the severity of the final cardiac event. The heart attack occurred on July 22, 2025, in London, at the age of 76.

The Five Major Health Battles That Defined His Final Years

To fully grasp the context of Ozzy’s passing, it is essential to understand the constellation of health challenges he faced, particularly in the last two decades of his life. These struggles, though not the direct cause of death, severely impacted his quality of life and contributed to his overall frailty.

1. Parkinson’s Disease (PRKN 2)

In 2020, Ozzy and his wife Sharon publicly revealed his diagnosis of Parkinson’s disease, specifically a form called PRKN 2, which he had been living with since 2003. Parkinson’s is a progressive neurological disorder that affects movement. For Ozzy, it caused tremors, slowed movement (bradykinesia), and difficulty with balance and coordination. This diagnosis was a major factor in his decision to retire from touring, as the physical demands became too great.

2. The Devastating 2019 Fall

Perhaps the most debilitating event was a fall he suffered at home in 2019. This accident aggravated injuries from a near-fatal quad bike crash in 2003. The fall dislodged metal rods that had been implanted in his neck and back from the previous accident. This led to years of excruciating chronic pain and a series of major, complex surgeries.

3. Multiple Spinal and Neck Surgeries

Following the 2019 fall, Ozzy underwent numerous, highly invasive surgeries to correct the damage to his spine and neck. These procedures were intended to alleviate nerve pain and stabilize his back, but they resulted in a long, difficult recovery period. He described the treatment as extensive and often depressing, as the lack of mobility took a heavy toll on his mental health.

4. COVID-19 and Other Infections

In 2022, Ozzy contracted COVID-19, which, given his underlying health conditions and age, was a significant scare. He also battled several other infections over the years, including a serious hand infection in 2018 that required multiple surgeries. Each new illness or infection further depleted his physical reserves, making his body less resilient to major events like a heart attack.

5. The Mental Health Toll of Immobility

The constant pain and inability to tour—the activity that gave him the greatest joy—led to significant depression. In interviews, he spoke openly about the profound mental health challenges that accompanied his physical decline. His final wish, which he managed to fulfill just 17 days before his death, was to perform live one last time, which he did at the "Back to the Sabbath" event on July 5, 2025. This final performance was a poignant, powerful farewell to his fans and a testament to his enduring spirit.

The Legacy That Will Never Die

While the official cause of death was a heart attack, the true story of Ozzy Osbourne’s final years is one of perseverance against a relentless barrage of health crises. His journey from the streets of Birmingham to global superstardom, followed by his candid struggles with addiction and illness, cemented his status as a true rock and roll survivor.

The outpouring of grief and tributes following his passing highlighted his immense topical authority in the world of heavy metal and popular culture. His legacy is not just in the music of Black Sabbath or his solo work, but in his honesty about his health, his family’s love, and his unwavering desire to perform until the very end. Though the Prince of Darkness is gone, his music, his persona, and his extraordinary life continue to inspire millions of fans worldwide.
