Lady Gaga was recently hospitalized at a local Denver hospital, and she showed off what she was hooked up to in an Instagram post.

The reason why she was brought in was because she was suffering from altitude sickness. Makes sense for the extreme change in altitude in Denver.

"Altitude Sickness is no Joke!" Gaga wrote for the caption on the photo. 

Check out Gaga's post below. I'm sure A.J. is rooting for her to make a quick recovery!
