Demi Lovato is sick of getting sick, so she's decided to have her large tonsils removed in a surgical procedure she'll undergo in less than two weeks.

"I've been meaning to get them out for years and years, but my career has just been going, going, going," she told Alan Carr on his "Chatty Man" talk show. "The thing is, I keep getting sick. Like once a month I get really sick. They're actually not doing me any good, so they're being removed."

The star recently spoke to Wonderwall MSN about the upcoming surgery. "[I'm having them out] in like a week and a half, so ... I'm nervous!," she admitted. "The whole thing is just really nerve wracking for me. I have a lot of people around me and it's just your tonsils, it's not anything serious. But, anybody that has to have surgery, regardless of how little or small, it doesn't sound fun."

Removing her tonsils has caused her to delay her tour for her new album "Demi" that hit stores this May, debuting at #3 on the Billboard charts. The "Heart Attack" singer recently prepped her new single "Made In The USA" for radio release, and the music video is expected to premiere on July 17.

Lovato explained that her fourth studio album is "a lot more vulnerable and more honest, raw, but there's also more catchy radio-friendly songs."

"I've always wanted to have songs on the radio and finally, I have an album where there aren't any album fillers," she said. "We wanted an album where every song that I put out could be a potential single."

Her song "Really Don't Care" featuring Cher Lloyd from her new album hasn't even been released as an official single, but so far the song has peaked on its own at #98 on the Billboard Hot 100 charts without any promotion from Lovato's label or management. She has performed the bubbly track plenty of times at concert appearances, but there is no word yet on whether or not Hollywood Records plans to release it as her 3rd single from "Demi."

But "Demi" isn't just full of radio-friendly hits. The track most special to Lovato is "Warrior," an emotional rollercoaster of a song that details her personal struggles from childhood to now.

"It's a song that's basically about overcoming some really difficult times in my life," the star told MSN. "I'm very open with a lot of the things that I've been through, but there's some things that I don't really like to talk about and this song is so personal that it makes it more inspiring to me."

In a recent interview with Cosmopolitan for her August 2013 cover issue, Lovato was hesistant to go into detail about the lyrics: "I need to take back the light inside you stole/You're a criminal/And you steal like you're a pro" and "There's a part of me I can't get back/A little girl grew up too fast/All It took was once/I'll never be the same."

"My family knows what it's about. When I'm ready to open up that subject with the outside world, then I'll be free to talk about it. But right now, it's kind of one of those things where the lyrics speak for me. It's all in the song," she said.

The star will reprise her role as a judge and mentor on the upcoming season of the US "The X-Factor" this fall, having been filming auditions with co-stars Simon Cowell, Kelly Rowland and Paulina Rubio this summer.
