Hello and thanks for the query
As per your mail it seems that your child is suffering from Typhoid
. He has low grade fever
with loss of apatite and probably general weakness. But needs to be investigated clinically and pathologically. Consult your doctor and get your widal test
done and according to that take a complete course of antibiotic.
Till that give your child a light small diet in multiple doses. Give paracetamol
in fever and body aches. And please don't give Pizza and other junk food.
Hope this will help you.
