The world of rock felt a little quieter on July 22, 2025. That was the morning we lost the Prince of Darkness. Ozzy Osbourne was 76. Honestly, for a guy who once famously bit the head off a bat and survived decades of "legendary" substance use, most fans thought he might actually be immortal. But the human body has its limits, even when it belongs to the frontman of Black Sabbath.
So, what was the actual cause of death ozzy osborne?
According to his death certificate and family statements, the primary cause was a heart attack. But if you’ve followed Ozzy over the last few years, you know it wasn’t just one thing. It was a snowball effect. A long, grueling battle with Parkinson’s disease (specifically a rare genetic form called PRKN-2) and coronary artery disease had left his system fragile.
He didn't just fade away, though. He went out on his own terms, which is the most "Ozzy" way possible.
The Final Bow in Birmingham
Just 17 days before he passed, Ozzy did something doctors told him he shouldn't do. He performed. He took the stage at the "Back to the Beginning" concert in his hometown of Birmingham on July 5, 2025. He was in a throne for much of it because he couldn’t walk anymore.
Sharon Osbourne later told Piers Morgan that doctors warned him. They said if he did that show, he might not make it through. He did it anyway.
The man lived for the stage.

A Medical Timeline of the Prince of Darkness
To understand why his heart finally gave out, you have to look at the "nightmare" (his words) of the last five years. It wasn't just the Parkinson's. It was a brutal cycle of injuries and surgeries that would have leveled a man half his age.
- 2003: A near-fatal ATV accident in England. This was the start of the "hardware" in his body—metal rods in his neck and back.
- 2019: A nasty fall at his home in Los Angeles. This fall dislodged the metal rods from the 2003 accident. He underwent several surgeries to fix it, but he never really recovered his mobility.
- 2020: Ozzy officially announced his Parkinson's diagnosis on Good Morning America. He'd actually known since 2003, but the symptoms became impossible to hide.
- Late 2024: A "secret" fall resulted in a fractured vertebra. This was followed by pneumonia and sepsis.
- July 2025: 17 days after his final show, he suffered a fatal heart attack at his home in Jordans, Buckinghamshire.
His son, Jack, recently shared on The Osbournes Podcast that by March 2025, the family thought they were going to lose him. The sepsis was "draining every ounce of strength he had." He was effectively fighting for months just to get to that last Birmingham stage.
Why the Heart Attack Happened
While the heart attack was the immediate cause, the underlying coronary artery disease and the chronic stress of his neurodegenerative condition played massive roles. Parkinson's doesn't usually kill you directly. It's the complications—respiratory issues, falls, or the massive strain on the cardiovascular system—that do.

In Ozzy's case, his heart simply couldn't keep up with a body that had been through seven surgeries in five years.
The Reality of Living with PRKN-2
People often ask if the "rock star lifestyle" caused the Parkinson's. Experts like Dr. Brandon Crawford have noted that while the lack of "natural rhythms" (touring, late nights, substance use) didn't help, Ozzy’s specific form was genetic. It's a slow-evolving version of the disease, but by 2025, it had stolen his ability to walk and made speech a struggle.
He used a cane. He had tremors. He worked with a physiotherapist five days a week.
"Survival is my legacy," he told PEOPLE in 2022. He wasn't kidding.
What He Said at the Very End
Sharon shared some of the more heartbreaking details about his final hours. On the morning he died, he had actually woken up and tried to work out—he was still trying to get stronger. His final words to her were reportedly, "Kiss me" and "Hug me tight."
He was buried in a private ceremony near his home in England.
Fans have since started a petition to rename the Birmingham Airport in his honor. It already has over 75,000 signatures. It’s a fitting tribute for a guy who went from a "shuffling" kid in Aston to a global icon.

What We Can Learn From Ozzy's Journey
If there’s any takeaway from the cause of death ozzy osborne, it’s a lesson in pure, stubborn resilience.
- Listen to your body, but don't let it define you. Ozzy was in pain every single day for years, yet he recorded two hit albums (Ordinary Man and Patient Number 9) in his 70s.
- The importance of a support system. Without Sharon and his kids, it’s unlikely Ozzy would have made it through the 2019 injuries. Having people who advocate for your health is vital.
- Legacy isn't about being perfect. It’s about showing up. He showed up for that last concert in a chair, voice cracking, but he gave his fans exactly what they needed—one last goodbye.
If you're a fan looking to honor his memory, skip the "bats" and consider donating to the Michael J. Fox Foundation for Parkinson’s Research. It was a cause the Osbourne family supported heavily in his final years. You can also visit his official website to see the tributes flowing in from around the world.
