Can a person with Gilbert's Syndrome still drink alcohol (1-2 drinks) per day or is it dangerous since Bilirubin is already elevated?

Gilbert's syndrome. This is harmless. But excess alcohol can poison anyone's liver. I do not know what size drink you are talking about. 2 Oz a day is max recommended for most but less is better. Any Alcoholics in your family? Beware then due to this but Gilbert's is no worries.
