The ever-chipper America's Got Talent host revealed today on his morning radio show that he was briefly hospitalized last week with two blood clots in his lung and an enlarged right ventricle.
So, what did the doctor advise the relentless multitasker, who was treated for mild kidney failure right after New Year's, to do?
"My doctor was saying that my work is going to kill me—and he's not joking," Cannon told his 92.3 NOW-FM audience. "I think part of the reason why my health did kind of deteriorate was because I wasn't resting a lot and I was doing too much. I was overworking myself, working out too much."
Plus, he was informed that people who travel by airplane as much as he does can be prone to blood clots.
"It was quite serious," Cannon said. "I was trying to downplay it a lot, even in my own mind. I travel a lot. Anyone who flies a lot can be a victim to getting blood clots because it can start in your legs or your lower back. That, on top of my previous condition made me more prone to it."
So, is Mariah Carey's 31-year-old husband finally going to stop saying yes to every gig?
"I always took a lot of pride in working so hard and never taking a day off," Cannon admitted. "But I'm learning that it isn't the wisest thing all the time, especially being a new father. Not only wanting to spend more time with my children, but wanting to be there for my children."
Surely, Mariah and their 9-month-old twins, Monroe and Moroccan, will appreciate it.
The good news is that, instead of having to constantly jet between L.A. and New York City to shoot AGT, the show has relocated to NYC to accommodate new judge Howard Stern's schedule. So that's less air travel right there!
