premise: Parents of 48 children ( 31 boys , 17 girls ) were interviewed . The main distressing symptoms were fatigue , pain , loss of appetite , and dyspnoea according to the parents . While parents perceived pain and constipation to have been treated successfully , loss of appetite and anxiety were not treated effectively . Why has it been difficult to improve and treat the symptoms of loss of appetite and anxiety ?
hypothesis: those issues are in the mind and not genuine , the way that the other symptoms are , so they can not simply be healed because they do n't truly exist medically
