Studies suggest trauma is associated with alterations of the gut microbiota and dysbiosis early in life could promote the development of PTSD later in life when subjects are re-exposed to traumatic events. This particularly applies to PTSD patients characterized by long-lasting low cortisol levels. This would consider the gut microbiota as a new biological factor mediating vulnerability versus resilience to stress and may suggest new targets in the treatment of PTSD.
