People with Gilbert's syndrome should consume a nutritious diet and eat meals on a regular schedule, according to Mayo Clinic. They should avoid fasting and take steps to prevent dehydration, states Genetics Home Reference.
Gilbert's syndrome is a genetic condition in which the liver fails to process bilirubin properly, and this leads to a build-up of bilirubin in the blood at certain times, explains Mayo Clinic. People with this condition may develop jaundice, a yellowish cast to the whites of the eyes and the skin, when their bilirbuin levels rise. Dehydration and fasting or eating foods with low caloric content can cause bilirubin levels to rise. Vigorous exercise, lack of sleep, menstruation, stress and illness also can cause elevated bilirubin levels.
While about 30 percent of those with Gilbert's syndrome have no symptoms, others experience abdominal pain or fatigue in addition to jaundice, states Genetics Home Reference. Diagnosis of Gilbert's syndrome often occurs accidentally during routine blood work, and patients often receive a diagnosis during adolescence.
Treatment isn't necessary for patients with Gilbert's syndrome, advises Mayo Clinic. When bilirubin levels rise, jaundice may occur, but it dissipates on its own. Gilbert's syndrome impacts the body's response to various medications, so people with this condition must advise their doctors of the condition's presence.
