The DSM 5 has taken away EDNOS. There is now OSFED(Otherwise Specified Feeding Eating Disorders) and OUFED(Otherwise Unspecified Feeding Eating Disorders). These are the new EDNOS. I guess the purpose was to specify more between the disoders to get more insurance coverage for these conditions.

You can now be Anorexic, while not being underweight. This is called Atypical Anorexia. This is just as serious as anorexia because starvation still affects your internal organs, no matter your size. People die from this regardless of size.

There is also now Orthorexia, which is an obsession over being "Healthy". Like obsessing over eating healthy and obsession over excercise. I am not a professional. I just know more about certain Eating Disorders, especially Atypical Anorexia, because I have been diagnosed with that. It is best to find a specialist who specializes in Eating Disorders. Dieticians who don't specialize in eating disorders aren't necessarily helpful. Now-a-days they are taught from societies standards that aren't all accurate when it comes to things about "healthy". That is actually something I was told from another dietician.

I hope that this information is somewhat helpful and that you are able to find some help.
