 Jochanan Naschitz Reviewer: 
Reviewer's report: 
General This study fills a gap in our knowledge on CFS. The authors are to be congratulated. The 
following points seserve emphasis: First, CFS in the study group might be more severe and of longer 
duration than in other studies. Hence, GI disturbances in this study group might be different than in 
CFS patients of lesser duration and severity of the disorder. Second, data on autonomic nervous system functions is not reported. It would interresting to correlate variables of GI functioning with 
variables of cardiovascular reactivity or other parameters of autonomic nervous functioning.
