Nick Cannon admits that he has been in denial about his recent string of "serious" health issues.

The 31-year-old America's Got Talent host was hospitalised last Friday in order to treat blood clots in his lungs and an enlarged ventricle on the right side of his heart.

Nick, who is still recovering from the mild kidney failure he suffered from over the holidays, has been in denial about the gravity of his maladies.

"It was quite serious. I was trying to downplay it a lot, even in my own mind," Nick said on his 92.3 NOW morning radio show. "[I'm] doing extremely well right now [though]."

Nick attributes last week's health scare to more than one cause.

"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 [from sitting for an extended period of time]," Nick explained. "That, on top of my previous condition made me more prone to [getting blood clots]."

Nick, who has 10-month-old fraternal twins Monroe and Moroccan with wife Mariah Carey, believes that he needs to take it easy professionally if he wants to preserve his health. He wants to be there for his family for many years to come.

"My doctor was saying that my work is going to kill me - and he's not joking. 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," Nick shared.

"I always took a lot of pride in working so hard and never taking a day off. 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."
