Individuals diagnosed with borderline personality disorder (BPD) often report experiencing physical ailments, even when there are no sufficient medical explanations. Research consistently shows that those with BPD exhibit increased dissociative symptoms, although these symptoms are generally not as severe as those found in primary dissociative disorders. Experiences of childhood abuse, neglect, and complex trauma are commonly associated with BPD symptoms, dissociation, somatization, and PTSD. Rather than indicating distinct physical problems, somatic symptoms in BPD patients appear to be closely linked to dissociation, trauma-related psychopathology, and emotional dysregulation. Dissociation may act as a maladaptive mechanism for coping with intense emotional experiences, with both physical and dissociative symptoms potentially reflecting trauma and PTSD symptoms. Studies suggest that reducing PTSD related distress could lessen the severity of physical symptoms, highlighting the importance of comprehensive, trauma-informed care.
