Hi, My dad (60 years) was being troubled with loss of appetite, sleeplessness and body weakness for about a month. We have referred 'General Physician' as well as a 'Psychiatrist' for this. All the body tests are normal and he suffers from mild high BP and is borderline diabetic. However, even after 15 days of continuous medications, the 'body weakness' problem isn't being resolved. The apetitite is slowly improving and he is having very sound sleep, however, the fatigue doesn't seem to lose him. I am very unsure which doctor (specialist) to refer to now as he seems to be weakened each passing day. Kindly Guide. Regards.
