It has been reported that some patients have been misdiagnosed with Body Dysmorphic Disorder, when in fact the correct diagnosis in their specific case was Anorexia Nervosa.
Treatment of anorexia nervosa is a multi-targeted approach. It includes doctors and dietitians to help achieve and maintain a healthy weight. Hospitalisation is required if the lack of nutrition leads to serious conditions. A mental health professional is also required to help the patient understand about the benefits of a healthy diet. The doctor will need to rule out any other medical conditions that ay result in weight loss. A mental health professional can help in diagnosing anorexia nervosa based on the symptoms and a mental exam of the patient.
