Sadorexia is a 2nd generation eating disorder characterized by a pervasive combined pattern of partial anorexic, bulimic or orthorexic behavior and non-traditional slimming techniques like severe masochism to achieve extreme, top-model-type thinness while strongly alleviating anxiety and without raising suspicions in friends or relatives. Sadorexia is usually regarded as an 'evolution' of traditional eating disorders as well as self-injury: a result of medical smugness, prohibitionist approaches, denial of causal factors and self-bloating of those who should have been working for solutions.

Sarorexia was discovered in Spain by WANBULA grassroots group (Webs Against Anorexia and Bulimia, in Spanish) and reported by AECA.
