Anorexia, bulimia, binge eating disorder, ARFID, and OSFED may be the most notorious eating disorders, but many lesser-known conditions often fly under the radar, going undiagnosed and untreated. Though they may not have made it to the pages of the DSM or receive an official diagnosis, they're just as real and devastating.

While anorexia and bulimia nervosa are the most recognized eating disorders, several lesser-known eating disorders also significantly impact those suffering. There are eight different diagnoses within the Feeding and Eating Disorders chapter of the Diagnostic and Statistical Manual 5th edition- text revision (DSM-5-TR), a comprehensive manual covering all psychiatric and related diagnoses in the healthcare field.
