My son has every sign and symptom of a liver problem but the jaundice is very hard to notice. is that normal?

?Gilbert Syndrome?: It is possible that he has the common hereditary cause of increased bilirubin, gilbert's syndrome, and is found in up to 5% of the population. The build-up of bilirubin can cause mild jaundice, but usually nothing else. Usually the liver can breakdown bilirubin quickly and u pee it out, but in this case it can't do it fast, thus a build up. But the level is usually harmless. Consult doc. Good luck.
