Hi Robbiekay, I am 26 years old, I have both cystic fibrosis and cystic fibrosis related diabetes and I received a successful lung transplant when I was 24 years old. I like you son began the evaluation process when I was 22. I'm not going to lie, the process takes a bit of time depending on how sick your son is. If he is getting very sick much much more quickly chances are they will speed up the evaluation process. Most of the time the transplant team wants to get a person on the transplant list as soon as possible because we just don't know how long you will be on the waiting list for. It may be a day it may be a year. I was on the list for a month before I got my first false alarm (a call that doesn't actually work out) In the end I didn't actually receive a call. I was so sick that I got placed in the ICU on life support and waited in the hospital until the new lungs came, it was very very close for me. The evaluation process itself involves doing lots of medical tests like lots of blood work, CT scans, a test to see how much stomach acid is in your stomach and a few other minor tests. Once the doctors and the social workers get all of the test results and talk to you and your family personally they "transplant panel" which are the doctors, surgeons and social workers get together and decide 1) if you qualify to get onto the list and 2) what your sons Lung Allocation Score is. This score determines where he will be on the transplant list. Once you are on the list it is pretty much a waiting game. Like I said before it could be a week, it could be a month, it could be a year. In terms of what you and your son should do through this process I would recommend a few things 1) get as informed as humanly possible about every aspect there is about lung transplant, about cystic fibrosis, about the lung transplant process. I found the more informed I was going through the process the more relevant questions I could ask to better help yourselves and your entire family through the transplant and recovery process. 2) Be 100% completely honest with your transplant team. Leave no stone unturned when it comes to how you, your family and your son feel physically, mentally, emotionally and psychologically about the transplant and getting the transplant. 3) ask as many questions as you can, there is no such thing as a stupid question when it comes to the transplant process 4) continue to talk to other people who have had transplants and who have gone through the transplant process. Obviously everyone's transplant story is different but they are also similar in many ways. Other transplant recipients and parents can give you tips and tricks on how to get through the entire transplant thing. 5, and I feel is MOST important) although he has not gone through the transplant yet he needs to start preparing for it now... especially psychologically and mentally. It is a tough tough tough thing to go through, probably one of the hardest things your son and your entire family will go through and the more mentally prepared you are the better the outcome will be. And that doesn't just mean your son, that means the entire family and whoever will be involved in the transplant. Its not just the person who goes through this process, its the entire family. I know you are probably scared right now and overwhelmed with new information, I completely understand, I know myself and my family were when we first started this process but try not to be. The best thing you can do is take it one day at a time, one step at a time. I think that is the best way to be successful. Like I said before I'm not going to lie to you, it is the hardest thing I have ever gone through. I literally went to hell and back fighting for my life but at the same time I learned what true human kindness and compassion was (my nurses, doctors and surgeons) I appreciate life so so so much now I can't even put it in words, and it has made me an overall better person. I've had complications, I've had struggles, I've had the highest of highs and the lowest of lows but I wouldn't change a thing because I am alive. Since my transplant I have fallen in love, graduated college, traveled, and spent countless precious hours with my friends and family. All of the pain and struggle were totally worth it. If you would like to talk to me more about the entire transplant process and ask me some questions please do not hesitate to private message me. I can even give you my cell number and we can talk over the phone. That goes the same with your son as well. I remember what it was like starting the process at his age and it was scary as hell. He, you and your family will need as much support as possible, don't ever be afraid to ask for it. There are so many people in this community who support your son and your family and we want nothing but the best for you. Sending you nothing but love, best wishes, and healthy thoughts. I hope you have a great week and please tell your son for me he has a fellow CF fighter in California who has his back always!!
