Sinéad O'Connor's official cause of death has been revealed one year after her passing in July 2023.

The legendary singer-songwriter died at the age of 56 from chronic obstructive pulmonary disease and asthma.

A UK coroner confirmed her cause of death as an exacerbation of these conditions along with a lower respiratory tract infection.

Initially, the coroner in London reported her death as natural but did not provide specific details.

O'Connor was found unresponsive in her London apartment on July 26, 2023.

In the wake of her death, numerous tributes celebrated O'Connor's profound impact on the music industry.

O'Connor had publicly struggled with mental health issues, particularly following the death of her 17-year-old son Shane in 2022.

She is survived by her three children, including her son Shane, who tragically died by suicide in 2022.

Her family announced her passing with a statement expressing their devastation and requesting privacy during this difficult time.

To commemorate the one-year anniversary of her passing, Dublin's National Wax Museum unveiled a wax figure of O'Connor, which faced criticism from fans.

The director of O'Connor's documentary, 'Nothing Compares,' announced it would be available to stream for free for a week to honor her legacy.

The Irish Independent reported that O'Connor died from a combination of chronic obstructive pulmonary disease, asthma, and a respiratory tract infection.
