Anorexia

Anorexia nervosa, often referred to simply as anorexia,[11] is an eating disorder characterized by low weight, food restriction, body image disturbance, fear of gaining weight, and an overpowering desire to be thin.[1] Anorexia is a term of Greek origin: an- (ἀν-, prefix denoting negation) and orexis (ὄρεξις, "appetite"), translating literally to "a loss of appetite"; the adjective nervosa indicating the functional and non-organic nature of the disorder. Anorexia nervosa was coined by Gull in 1873 but, despite literal translation, the symptom of hunger is frequently present and the pathological control of this instinct is a source of satisfaction for the patients. https://en.wikipedia.org/wiki/Anorexia_nervosa

Pro-ana is the promotion of behaviors related to the eating disorder anorexia nervosa. It is often referred to simply as ana.[1] The lesser-used term pro-mia refers likewise to bulimia nervosa[2] and is sometimes used interchangeably with pro-ana. Pro-ana groups differ widely in their stances. Most claim that they exist mainly as a non-judgmental environment for anorexics; a place to turn to, to discuss their illness, and to support those who choose to enter recovery. Others deny anorexia nervosa is a mental illness and claim instead that it is a "lifestyle choice" that should be respected by doctors and family.[1] The scientific community recognises anorexia nervosa as a serious illness. Some research suggests anorexia nervosa has the highest rate of mortality of any psychological disorder. https://en.wikipedia.org/wiki/Pro-ana
