Ozzy Osbourne, the legendary frontman of Black Sabbath and one of the most iconic figures in rock history, passed away on July 22, 2025, at the age of 76. Known worldwide as the Prince of Darkness, Ozzy’s death marks the end of an era for heavy metal and rock fans across the globe.
Official Cause of Death Revealed
According to his death certificate, Ozzy died from an out-of-hospital cardiac arrest caused by an acute myocardial infarction — a medical term for a heart attack. Additional contributing factors included coronary artery disease and Parkinson’s disease with autonomic dysfunction, a condition that affects involuntary bodily functions like heart rate and blood pressure.
His death certificate also proudly noted his occupation as “Songwriter, Performer and Rock Legend,” reflecting his immense impact on the music world.
A Long Battle With Health Issues
Ozzy had been battling multiple serious health problems for years. He was first diagnosed with Parkinson’s disease in the early 2000s, though the diagnosis was publicly confirmed only in 2020. The condition affected his balance, mobility, and speech, but he continued to remain active and creative despite it.
His health further declined after a quad bike accident in 2003, which left him with severe injuries, followed by a bad fall in 2019 that worsened his spinal condition. Multiple surgeries and infections over the years took a heavy toll on his body.
