Hello! Thanks for putting your query in HCM. I am a Gastroenterologist (DM).
Isolate increase in bilirubin may be due to few causes only like
hemolytic anemia, drug induced,some inherited disorders, and ineffective
erythropoiesis due to vitamins deficiency
You need to be evaluated with blood tests like serum bilirubin (total, direct and indirect), complete hemogram with absolute reticulocyte counts and other levr function tests like
serum albumin, SGOT/SGPT, serum
alkaline phosphatase and ultrasound abdomen. So get these tests done and accordingly management
I hope I have answered your query and this will help you. Remain in touch and get-well soon.
