前央视主持人王小骞哭诉11岁女儿患正食症！“正食症”是一种什么病？

Core Viewpoint - The recent case of Wang Xiaoqian's daughter suffering from Orthorexia Nervosa has brought attention to this eating disorder, which is characterized by an excessive focus on healthy eating, leading to severe dietary restrictions and potential nutritional deficiencies [4][5]. Group 1: Definition and Characteristics - Orthorexia Nervosa, translated from English, refers to a strict limitation on diet in pursuit of an overly "healthy" and "pure" eating pattern, which can lead to malnutrition [4]. - Unlike anorexia, which primarily aims at weight control, Orthorexia is driven by the belief in achieving a perfect diet, resulting in a narrow range of food choices [5]. Group 2: Health Implications - Patients with Orthorexia may experience significant weight loss and nutritional deficiencies, potentially evolving into anorexia if the condition worsens [5]. - The condition can lead to severe health issues, such as heart damage, as seen in Wang Xiaoqian's daughter, who exhibited a heart rate of 120 due to extreme dietary restrictions [4]. Group 3: Psychological Aspects - Both Orthorexia and anorexia may be associated with compulsive behavior patterns, reflecting cognitive biases and a high need for control [5]. - The underlying psychological motivations for these eating disorders often stem from environmental factors, such as a tense family atmosphere, leading individuals to exert control over their food intake [5].
