Any way to get a 6 pack even though I have a medical condition?

Okay well I know I’m young and it’s early to be thinking of stuff like this, but I mean….I want to do it, and I don’t want to feel bad about myself…I have a tracheal issue I’m not too sure if that will effect it or not, but is there any way? I’m willing to work on it. I “work out” I’m starting out slow though, just pull ups and push ups but I get enough works on my legs from my drumming (hardcore rock, heavy metal, metal. Double bass) So I’m pretty sure I’m good on that, but I do 20–25 push ups and 10–15 pull ups a day. I just need to work out on my abs or so…but still Is there a way for that even with my medical condition. I looked up some stuff on it and it said I needed to do lots of cardio but I’m not sure…Please, help?
