Keep reading to know more about it.

At the time of her death, Sinéad O’Connor was 56 years old.

Now, a year after her death, her death report was obtained, which revealed her cause of death.

The cause of death was chronic obstructive pulmonary disease and bronchial asthma combined with a low-grade lower respiratory tract infection.

This report comes six months after London Inner South Coroner’s Court confirmed that her cause of death was listed as “natural causes.” The singer achieved global stardom with her cover of Prince’s “Nothing Compares 2.”

Her death occurred on July 26, 2023, at the age of 56 years old.

“It is with great sadness that we announce the passing of our beloved Sinéad,” her family confirmed her death in a statement a year ago. It went on, “Her family and friends are devastated and have requested privacy at this very difficult time.”

According to the news, British police found the singer unresponsive. And said she had been “pronounced her dead at the scene” of her London home. The London Inner South Coroner’s Court said there would be an autopsy, but her death was not treated as suspicious.

O’Connor’s life was not free of struggles with mental illness and tragedy. Her son, Shane, died by suicide in 2022 at just 17 years old after he had been missing in Ireland. The singer herself publicly talked about committing suicide herself in recent years.

“I once heard Sìnead sing acappella in an empty chapel in Ireland. It was under construction at the private home of our host. It was one of the most beautiful things I’ve ever heard in my life. We then went together to see Eminem at a festival. I loved her. Her music. Her life. She was a victim of child abuse and a huge change agent for unfair and unjust draconian laws that she helped change in Ireland,” Jamie Lee Curtis wrote on Instagram after the singer had passed. “She was a warrior. She was a rebel. She ripped up a photograph that was on her mother’s wall because of the hypocrisy of the abusive life she was raised in under the banner of the church. This is so sad. Watch the NOTHING COMPARES documentary. Brilliant. Heartbreaking. Rest well. Rest in power. Rest in peace.”

In the weeks before her death, O’Connor took to Facebook with a more optimistic message.

“Hi All, recently moved back to London after 23 years absence. Very happy to be home : ) Soon finishing my album. Release early next year : ),” she wrote on social media on July 11. “Hopefully Touring Australia and New Zealand toward end 2024. Europe, USA and other territories beginning early 2025 : ) #TheBitchIsBack.”
