This is a partial list, but the majority of those with GWS reported symptoms such as cognitive deficits, autonomic dysfunction, Chronic Fatigue Syndrome, and widespread chronic pain that implicate the central nervous system.
Additionally, functional gastrointestinal disorders were reported by many. The functional speaks to chronic symptoms related to the digestive tract. The "functional" here refers to an organ with no alteration to the organ tissue yet not functioning normally. A comparative example could be irritable bowel syndrome.
