Anorexia Recovery & Treatment

Ever wonder this? Obviously anorexia nervosa is a recognized mental disorder that can lead to death. But, why isn’t extreme bodybuilding? You know where men take steroids and looking so unaturally buff and extremely unhealthy. I mean obviously anorexia nervosa and exteme bodybuilding are caused by emotional, biological, and environmental factors. But I just don’t understand why extreme body building isn’t considered a mental disorder? Is it because you don’t have a chance of dying, unlike anorexia?
