Ozzy Osbourne was aware of his health worsening before his death

Author Benedetta Baldin - 7.10.2025

Shortly before he passed away from a heart attack, Ozzy Osbourne was aware that he had severe heart issues, as loudersound reports. The heavy metal legend discloses that he suffered from arrhythmia and “a dodgy heart valve” in his dying weeks in the penultimate chapter of his upcoming memoir, “Last Rites”. The chapter was written following Osbourne‘s July 5th, this year, retirement show, “Back To The Beginning”. On July 22, the singer passed away. He continues by explaining that a recent sepsis infection was the source of his cardiac problems. In 2023, following his final spinal surgery in a lengthy series of surgeries, he became infected.

It’s never silly little things, it’s always life-or-death. The valve is 80 percent blocked, apparently. The sepsis also gave me something called arrhythmia – when your heart can’t keep time, like a drummer in a bad pub band – so cheers for that.

He continues by saying that doctors declined to operate on his valve because doing so “would be too dangerous” because it would require him to stop taking the blood thinners he was taking to treat his Parkinson’s illness.

Meanwhile, the thinners mean if I ever fall over, I’d bleed out in about five seconds. I’ve honestly lost count of the ways in which getting old sucks.

When Osbourne got a staph infection in two of his fingers in 2018, his late-life health problems began. They went on when he fell in the middle of the night at home in February 2019. His injuries from a quad bike accident in 2003 were made worse by the fall, which required several major surgeries. In 2020, the artist disclosed that he had Parkinson’s disease. Osbourne repeatedly postponed parts of his final tour, “No More Tours II”, as a result of these failures, before abruptly canceling the performances and ending his touring career in 2023. For the first time since September 2005, he shared the stage with his fellow Black Sabbath founding members in “Back To The Beginning”. At the all-day event, which took place at Villa Park football stadium, close to Osbourne‘s childhood home in Aston, Birmingham, he also performed solo.

Seventeen days after “Back To The Beginning”, Osbourne passed away at his home in Buckinghamshire. After his cortége passed through Birmingham in front of tens of thousands of admirers in sadness, he was given a private funeral on July 30. Prior to Osbourne‘s passing, on July 10, Last Rites was revealed. It will be published today by Sphere Publishing.
