The first episode was the "pilot". They had to air it once to see the amount of ppl tuning in - they are looking for people to make more episodes as well. You can find it on TLC's website if you want to participate. I totally would but you have to have a way to pay for your surgery and have a surgeon picked out etc. There will be more episodes once more ppl let TLC follow them during the journey.
(this information is coming from TLC.com and Sarah from the show, she's on facebook and youtube, I've followed her for a few years now)
