Most EDs are mental, not weight driven (although weight can be a trigger), and I think the perfectionist and intense skill aspect of the sport might drive some of the more critical kids to extremes. With all the talk about mental blocks and worlds teams and whether it's a failure not to progress … I just want to grab every cheerleader and give them a hug. What we do is so intense and crazy, with HS and college and work and life on top of it all, it's amazing that cheerleaders still smile on the mat.
As a recovering/ed anorexic, cheer has helped me to keep from relapsing because I know I need to eat to fight for those stunts that don't hit, or just get the stunts up in the first place. It's a safety matter for me as well as the team. The reality is that you can't get through training or comp season without a healthy body and sound mind. If you suspect anyone is suffering from early stages, speak up! Talk to coaches or family and make sure they take your concerns seriously. This is a life-long mental disease and sometimes it's so frustrating having to fight it every day, I would not wish it on my enemies. For anyone with college or HS age girls, do preventative work and explain what EDs are, how they can hurt you and the importance of looking out for each other. There are workshops and motivational speakers, it can be a good bonding as well as educational experience. It won't be a failsafe, but if it helps just one girl on the edge then it's worth it.
