Demi Lovato Suffered Heart Attack and 3 Strokes Amid Overdose, New Doc Reveals

"I had so much to say over the past two years, wanting to set the record straight about what it was that happened," the singer says.

Demi Lovato was minutes away from death when she overdosed in July 2018, the singer-songwriter reveals in an upcoming documentary, Demi Lovato: Dancing With the Devil.

Lovato made headlines around the globe when she was rushed to the hospital on July 24, 2018, after she suffered an opioid overdose. What fans did not know was that she suffered a heart attack and three strokes amid the crisis.

"I had so much to say over the past two years, wanting to set the record straight about what it was that happened," Lovato shared in the trailer for the doc released on Wednesday. "Any time that you suppress a part of yourself, it's gonna overflow."

Making clear she was not going to hold back, Lovato revealed in the doc, "I had crossed a line that I had never crossed before. ... I snapped."

Following her overdose, Lovato was hospitalized for two weeks before entering an in-patient rehab facility. "My doctors said that I had five to 10 more minutes [to live]," she says in the doc about surviving the overdose. She also notes she is on her "ninth life."

Lovato revealed Wednesday during the virtual TCA press tour announcing her doc that she was also left with brain damage from the overdose. The four-part YouTube Originals documentary dissects the 28-year-old's life, speaking with family, friends and fellow artists, such as Elton John and Christina Aguilera. The documentary is directed by Michael D. Ratner.
