Gilbert’s Syndrome: Symptoms, Causes, Complication, Treatment And Lifestyle

Gilbert’s syndrome is a common, mild liver condition in which the liver doesn’t properly process a substance called bilirubin. Bilirubin is produced by the breakdown of red blood cells.

Gilbert’s syndrome is caused by an inherited gene mutation. You’re born with Gilbert’s syndrome, though it often goes undiscovered for many years. Gilbert’s syndrome is often discovered by accident, such as when you have a blood test that shows elevated bilirubin levels. Gilbert’s syndrome is also known as constitutional hepatic dysfunction and familial nonhemolytic jaundice.

Symptoms
The lone sign of Gilbert’s disease is that your skin and the whites of your eyes occasionally have a yellowish tinge (jaundice). This is caused by the slightly elevated levels of bilirubin in your blood. Some conditions and situations may increase bilirubin levels, and thereby jaundice, in people with Gilbert’s syndrome. These include:

Illness, such as a cold or the flu

Fasting or eating a very low-calorie diet

Dehydration

Menstruation

Stress

Strenuous exercise

Lack of sleep

The jaundice will go away when these conditions resolve.

Causes
Gilbert’s syndrome is caused by an abnormal gene that you inherit from your parents. The gene controls an enzyme that helps break down bilirubin in your liver. With an ineffective gene, excess amounts of bilirubin build up in your blood.

How the body normally processes bilirubin
Bilirubin is a yellowish pigment that’s made when your body breaks down old red blood cells. Bilirubin travels through your bloodstream to the liver. Normally an enzyme in liver cells breaks down the bilirubin and removes it from the bloodstream. The bilirubin passes from the liver into the intestines with bile. It’s then excreted in stool. A small amount of bilirubin remains in the blood.

How the abnormal gene is passed through families
The abnormal gene that causes Gilbert’s syndrome is common. Many people carry one copy of this abnormal gene. Two abnormal copies are usually needed to cause Gilbert’s syndrome.

Complications
Jaundice
Gilbert’s syndrome can cause episodes of jaundice. However, the jaundice is mild, goes away on its own and doesn’t cause any health problems. If jaundice persists, see your doctor.

Side effects with certain medications
The low level of the bilirubin-processing enzyme that causes Gilbert’s syndrome may also increase side effects with certain medications, since this enzyme plays a role in helping clear these medications from your body.

In particular, irinotecan (Camptosar), a cancer chemotherapy drug, can reach toxic levels if you have Gilbert’s syndrome, causing severe diarrhea. Some protease inhibitors used to treat HIV cause elevated levels of bilirubin in people with Gilbert’s syndrome.

Because of the potential for side effects, if you have Gilbert’s syndrome, talk to your doctor before taking any new medications.

Treatments
Gilbert’s syndrome doesn’t require treatment. The bilirubin levels in your blood may fluctuate over time and you may occasionally experience jaundice. But this usually goes away on its own, and it doesn’t cause any ill effects.

Lifestyle
Certain life events, such as stress, can trigger episodes of higher bilirubin levels in Gilbert’s syndrome, leading to jaundice. Doing what you can to manage those situations can help keep bilirubin under control.

These steps include:

Tell every doctor about your Gilbert’s syndrome. Gilbert’s syndrome affects the way your body processes certain medications. This has the potential to worsen side effects. Tell each doctor you visit that you have Gilbert’s syndrome, so any medications can be selected with this in mind.

Eat a healthy diet. Choose a healthy diet full of fruits and vegetables. Avoid extremely low-calorie diets. Stick to a routine eating schedule and avoid fasting or skipping meals.

Manage stress. Find ways to deal with the stresses in your life. Consider exercise or quiet time alone to cope with stress.
