Unless that is the only thing you're eating, consuming chapstick isn't one of the commonly seen signs of anorexia, although it is very bad for you and can even cause poisoning. However, everyone is different, and the signs of eating disorders are different with every case. If you're concerned that you or someone close to you may have an eating disorder such as anorexia or bulmilia, you should confide in a trusted adult and get help for yourself or the individual you suspect has this disorder.
Not eating / skipping meals, increased exercise, and a distorted self-image are all signs of anorexia, but diagnostic in and of themselves.
