Somatization is the experience and expression of psychological distress through bodily symptoms. Somatization can be conceptualized as an emotional state that has not been represented symbolically or as a defense against intolerable emotions and fantasies. Bodily concerns can also function as a means of seeking responsiveness from others. Alexithymia refers to a difficulty identifying and symbolizing emotional states that has been found to be associated with somatization. When functioning as a defense, a focus on the body can be used to avoid frightening or intolerable feelings and fantasies, or to ward off aggressive fantasies by viewing oneself as physically damaged. Systematic studies have demonstrated the presence of the defense of somatization in mood disorders, particularly anxiety and panic disorders. In treating anxiety disorders, the therapist helps the patient to determine the nature of emotions and fantasies that the patient is defending against, particularly fears and conflicts surrounding anger and separation.
