The bilirubin level rises as a result of infections such as 'flu, and when a person fasts or vomits. Many people are initially thought to have real liver disease, and undergo tests for this. They may even have a liver biopsy to rule out other conditions. X-rays and liver biopsy show that there is no liver disease. Gilbert's syndrome should not be regarded as a disease and people with the syndrome are not ill.
Symptoms are more likely to be the result of worry about the condition than of the condition itself.
