Hi welcome to the health care magic
You have been treated for
acute appendicitis by appendisectomy operation...
Your doctor is doing investigation in right way...
Although you are improving (
bilirubin level reducing), cause for elevated bilirubin should be searched by peripheral smear examination, USG abdomen, PT,
APTT, sgpt,
sgot etc . .
If specific cause found than treated accordingly...
Appendisectomy operation is not here probably cause for elevated bilirubin..
Sugar cane juice, carrots, green leafy vegetables, lemon juice, coconut water will be beneficial
Take care
Consult physician for examination with keeping all this in mind
Hope your concern solved
