I had a kidney transplant 14 years ago. i want to start skydiving on the weekends. any concerns?

Risky: You have one kidney. I would say you are taking a significant risk. The call is yours. Discuss with kidney donor if not cadaveric. When we find a child has a solitary kidney we discuss pros and cons of contact sports and let parents make a decision with their child.

I guess no: If you don't have any other medical issues and cleared by your docs, i would not anticipate any concerns. The only thing i want to mention is that if you have one working kidney but you may be cautious about damaging it.

Maybe not for you: My concern isn't that you have a kidney transplant, but that you say you have osteoporosis from your prednisone. Doublecheck with your physician -- you don't want a compression fracture.

All depends: Many renal transplant recipients have active lifestyle and transplant itself is not a contraindication to skydiving. If you are 28 years old and has no cardiac issues, I don't see a problem. However, since you have only one functioning kidney, you need to be careful not to sustain trauma that can cause irreversible damage to the allograft.
