Gilbert Syndrome (GS) is a relatively common inherited condition that is caused by a deficiency of an enzyme that conjugates the bilirubin. As a result of this deficiency, bilirubin can't be conjugated. Conjugation of bilirubin is necessary for its excretion from the body, therefore the main symptom in Gilbert Syndrome is excess bilirubin which causes juandice, fatigue, some abdominal pain at times, and difficulty metabolising certain medications. The good thing is that symptoms are generally mild, and most people do not require any treatment, unless symptoms are severe. On a even more positive note, people with GS actually even have a lower risk of heart disease.

There would be times when your bilirubin would get more elevated, for example during dehydration, stress, and certain illnesses like common cold. Avoid getting dehydrated and keep your stress under control.

Unfortunately, there is no vaccine for Hep C yet.

By the way, are your parents cousins to each other? Illnesses like Gilbert Syndrome happen more frequently in children whose parents are cousins.
