Context: 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 .

Question: Why has it been difficult to improve and treat the symptoms of loss of appetite and anxiety ?
Options:
0. Parents felt that those issues were not as severe and did not focus on fixing them
1. Loss of appetite and anxiety are closely tied to mental health issues and can not be fixed by way of medication as easily as the other symptoms , it takes much longer to overcome issues caused by psychology
2. The parents did not want to address those issues as importantly
3. 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
