The Official Cause of Death: Cardiac Arrest and Chronic Illness

The speculation surrounding Ozzy Osbourne's health had been rampant for years, fueled by his public battle with various ailments. However, the official cause of death, as confirmed by a death certificate filed in London, provided a definitive answer to the question of how he died.

The primary cause of death was listed as an out-of-hospital cardiac arrest (heart attack). This acute event was a result of underlying health conditions that the rock icon had been managing for years. The death certificate specifically cited Coronary Artery Disease as a contributing factor.

Crucially, the document also listed Parkinson's Disease with Autonomic Dysfunction as a significant condition contributing to his passing. Ozzy had been privately diagnosed with Parkin 2, a genetic form of Parkinson's disease, in 2003, though he only revealed the diagnosis publicly in 2020. Autonomic dysfunction, a common complication of advanced Parkinson's, affects involuntary bodily functions like heart rate and blood pressure, making the body more susceptible to a fatal event like cardiac arrest.

Ozzy's Final Years: A Domino Effect of Health Battles

Ozzy Osbourne's health decline was a slow, public battle that began long before his death in 2025. His final years were marked by a series of debilitating injuries and the progressive nature of his neurological disorder, Parkinson's. His wife, Sharon Osbourne, often referred to his various health crises as a "domino effect" that ultimately led to his passing.

The 2024 Fall and Spinal Injuries

A major turning point in his health came with a "little fall" in 2024. This seemingly minor incident exacerbated old injuries, causing a fractured vertebra. This was a devastating setback, as it followed a much more serious 2019 fall that required complex neck and spine surgery to fix damage from a 2003 ATV accident. The cumulative trauma left him in constant pain and severely limited his mobility, forcing him to officially retire from touring in 2023.

The Battle with Parkinson's Disease

The genetic form of Parkinson's disease, which he battled for over two decades, was a constant challenge. The disease, which affects the central nervous system, led to tremors, stiffness, and difficulty with balance and coordination. The inclusion of "Autonomic Dysfunction" on his death certificate highlights how the disease ultimately compromised the function of his vital organs, making the cardiac arrest a tragic, but related, complication of his long-term illness.

A Peaceful End: The Prince of Darkness’s Final Days

Despite his tumultuous life and the severity of his illness, reports indicate Ozzy Osbourne spent his final days in relative peace. He passed away at his home in England, having recently moved back to the UK from Los Angeles.

In the days leading up to his death, he was surrounded by his loved ones. A source close to the family noted that he was "at home amid the things he loves most," suggesting a quiet, comfortable end. His son, Jack Osbourne, confirmed that the rock legend was even working on his autobiography, finishing the final chapter just days before he died.

Sharon Osbourne shared emotional details of his final moments, revealing that he had a medical event after going downstairs to work out on the morning of his passing. She also shared his final, emotional words to her, which she keeps private but described as a moment of deep connection.

Ozzy Osbourne's life was a symphony of chaos and creativity, and his passing, while a moment of profound sadness, was the final, quiet note in a life lived louder than anyone else. His legacy as the frontman of Black Sabbath and a solo icon remains immortal, a true testament to the Prince of Darkness.
