My Step Was Admitted To A Hospital With High Billirubin

my step was admitted to a hospital with high billirubin in his blood. He is 20 years old. So far what they have told him is his gallbladder is slightly inflamed and have said nothing else. Consults arent coming til next morning to check him. Im worried.
Stepson...sorry He had adonminal pain 4 hours after eating for two days. Thats what prompted all this.
