Gilbert Syndrome

Definition

Gilbert syndrome is a genetic liver disorder. It causes levels of bilirubin to rise above normal levels. Bilirubin is a yellow chemical by-product of hemoglobin. Hemoglobin is the red pigment in blood cells that is usually excreted by the liver as bile.

Causes

Gilbert syndrome is usually caused by an inherited genetic abnormality. Symptoms occur when there is an interference with the liver enzyme that is important in the elimination of bilirubin. This causes the levels of bilirubin to increase in the blood, which may produce symptoms such as jaundice .

Risk Factors

Factors that increase your risk of Gilbert syndrome include:

  • Family members with Gilbert syndrome
  • Sex: male

Symptoms

Often, there are no symptoms of Gilbert syndrome. However, people who do have symptoms may experience:

  • Yellowing of the skin known as jaundice
  • Jaundice of the whites of the eyes
  • Abdominal pain
  • Loss of appetite
  • Fatigue and weakness
  • Darkening of the urine

Diagnosis

Your doctor will ask about your symptoms and medical history. A physical exam will be done. Tests may include:

  • Complete blood count (CBC)
  • Reticulocyte count
  • Total and direct bilirubin
  • Liver function tests

Blood tests are also done to rule out more serious liver diseases, such as hepatitis . Sometimes, a liver biopsy may also need to be done.

Treatment

No treatment is necessary for Gilbert syndrome. Usually, symptoms come and go.

Prevention

  • Skipping meals or fasting
