up to 1.2 bilirubin
level is not unusual rise in bilirubin level. it may be some due to diet facotor if you had no any symtomatic changes in eye, urine and any skin discoloration , loss of appetite etc there is no need to worry.
Itching may be due to the Obstructive jaundice
but in case of you i dont think to suspect any pathological condition..i suggest you if any symptoms arise beyond this have ultrasonography
and some other liver
functions test as well
but beware of alcohol and paracetamols like drugs
