Behavioural therapy and bariatric surgery often produce rapid, massive body weight loss that may impact a patient's ability to gauge his/her new body shape. Although the patient is aware of the weight loss, he/she continues to feel obese, as if there was a conflict between the previous body schema and the new one. Here, we report the case of a 40-year-old woman who developed major body distortions after massive weight loss. Psychometric and behavioural assessments revealed strong disturbances in several tasks involving body representation. In particular, we observed abnormal behaviour in a body-scaled action task. Our findings suggest that the rapidity of our patient's weight loss prevented her central nervous system from correctly updating the body schema.
行为疗法和减肥手术通常会导致体重迅速大量减轻，这可能会影响患者对自己新体型的感知能力。尽管患者已经意识到体重减轻，但他/她仍然感到肥胖，好像旧的身体图式和新的身体图式之间存在冲突。在这里，我们报告了一例 40 岁女性在体重大量减轻后出现严重身体扭曲的病例。心理测量和行为评估显示，涉及身体表现的多项任务存在严重障碍。特别是，我们在身体尺度动作任务中观察到了异常行为。我们的发现表明，患者体重减轻的速度过快，导致她的中枢神经系统无法正确更新身体图式。
