Conditions that may co-exist with Pediatric ME/CFS (co-morbid conditions)

The child or adolescent may have concomitant disorders "that do not explain fatigue, and are, therefore, not necessarily exclusionary: (a) psychiatric diagnoses such as school phobia, separation anxiety, anxiety disorders, somatoform disorders, depressive disorders."

Also, a child with pediatric ME/CFS may also concurrently have fibromyalgia and/or multiple food and chemical sensitivity. See the full pediatric definition for further concomitant illnesses.
