As previously reported by OK!, the 65-year-old was taken to hospital after he collapsed outside a Starbucks in Los Angeles on Wednesday, October 13. He later explained on Twitter that he was at "home and doing better" and that he passed out because he was dehydrated and had low blood sugar.
The America's Got Talent judge was joined by his daughter Jackelyn on his "Howie Mandel Does Stuff" podcast on Thursday, October 14.
"I was dehydrated. I had a colonoscopy a few days ago," he explained on the podcast.
"You take a drink and you empty out," he told his daughter. "I had consensual diarrhea the entire night. Most people don’t ask for it. I took something that gives you consensual diarrhea and then I was dehydrated."
"The moment I woke up from the colonoscopy I worked," he explained of what went wrong. "I did Logan Paul’s podcast and then I did [another] podcast. And all I kind of lived on was coffee and caffeine, which also exacerbates dehydration, I was told … Apparently when you do that you will pass out at Starbucks."
Later in the podcast, the former Deal Or No Deal host said that he doesn't think he lost consciousness but he "got really dizzy and couldn’t stand up."
"I got totally soaked with sweat," he recalled. "For somebody who’s dehydrated, I had a lot of sweat in me. And then next thing I know I was surrounded by the fire department and then they took me to the hospital, they did all these tests on my heart."
Despite the scary ordeal, Mandel said he's feeling "really good."
"First mom called me and she goes, 'Don’t worry. Everything’s OK.' I was worried and then she was like, 'We’re going to the hospital.' I was already freaking out but she said, 'Don’t worry,'" Jackelyn told her father. "Then I see [on] TMZ that there’s a crowd of people around you."
