Can I be an English instructor in Korea even if I have scoliosis?

Hello! I am preparing to teach English at a private academy in Korea, but I have a lot of concerns due to my scoliosis. I currently have a severe curvature of 50 degrees, but it doesn't pose a significant problem in my daily life. I had spinal fusion surgery when I was 6 years old, and now I am 35. Fortunately, thanks to the surgery, I don't experience severe pain or rapid progression of the curvature. The issue is whether I should disclose this fact before coming to Korea. I'm worried that if I don't mention it in advance, it might cause problems later, but on the other hand, I'm afraid that revealing it could reduce my job opportunities. I'm particularly concerned about being judged based on my appearance when I arrive in Korea. I am also exercising and trying to lose weight to improve my physical condition. If anyone has had a similar experience, I would appreciate your advice. I need tips on whether to disclose this and about living in Korea!
