The cause of death for Mandisa, the former American Idol star and Grammy Award-winning artist, has been disclosed in an autopsy report.

Mandisa was found deceased in her home on April 18th of this year.

A statement announcing her death read: “We ask for your prayers for her family and close knit circle of friends during this incredibly difficult time.

“Mandisa was a voice of encouragement and truth to people facing life’s challenges all around the world. She wrote this song for a dear friend who had passed in 2017. Her own words say it best:

‘I’m already home / You’ve got to lay it down / ’cause Jesus holds me now— / And I am not alone.’”

Following the announcement, tributes poured in, with fans describing her as “a beautiful and talented soul.”

“So very sorry to hear this,” one person wrote. “Her music encouraged me through some difficult moments in my life. Her voice and music will be dearly missed.”

Initially, the cause of death was not detailed, but an autopsy report obtained by PEOPLE has provided clarity.

The report states that Mandisa died from complications of class III obesity at age 47.

Her manner of death was listed as natural.

Class III obesity, formerly known as morbid obesity, is described by the Cleveland Clinic as “a complex chronic disease in which a person has a body mass index (BMI) of 40 or higher or a BMI of 35 or higher and is experiencing obesity-related health conditions.”

Mandisa was open about her struggles with mental health, admitting she turned to food for comfort. In a 2017 interview with PEOPLE, she said: “I didn’t leave the house, for the most part. When I got up, I went downstairs, sat in the recliner, and I watched television nonstop. The only time I left was when I got tired of pizza delivery and decided to get McDonald’s.”

Mandisa first gained fame after her audition for the fifth season of American Idol, earning high praise from the judges.

During her time on the show in 2006, she performed songs including Chaka Khan’s “I’m Every Woman” and Stevie Wonder’s “Don’t You Worry ‘Bout a Thing.”

In 2007, Mandisa released her debut album, True Beauty, and won a Grammy six years later.
