Gilbert syndrome is a common and harmless genetic condition that affects the liver’s ability to process bilirubin, which may lead to increased levels of this substance in the blood.
What is Gilbert syndrome and how does it occur?
This condition occurs due to an inherited genetic defect from the parents, affecting the gene responsible for producing an enzyme essential for breaking down bilirubin in the liver. Bilirubin is a yellow pigment produced when old red blood cells are broken down; normally, the liver processes it and excretes it from the body via bile and then stool. In the case of Gilbert syndrome, the deficiency of this enzyme leads to the accumulation of the substance in the blood.
The condition often appears during or after puberty because bilirubin production increases at this stage. The likelihood of occurrence increases if both parents carry the modified gene, and it is more common among men.
Symptoms and Triggers of Gilbert’s Syndrome
For many people, the condition may not cause any symptoms and is sometimes discovered by chance through blood tests. However, when they appear, signs include:
- Mild yellowing of the skin and whites of the eyes (jaundice).
- Feelings of fatigue, dizziness, or general malaise.
- Loss of appetite, nausea, or diarrhea.
- Abdominal discomfort or concentration problems.
These symptoms can intensify when exposed to certain triggers, such as:
- Infections or illnesses like the common cold and influenza.
- Fasting, following a low-calorie diet, or dehydration.
- Psychological stress, exhaustion, or lack of sleep.
- Strenuous physical exercise or undergoing surgery.
- Menstruation or alcohol consumption.
Diagnosis and Treatment
Diagnosis is typically performed via clinical examination and blood tests (complete blood count and liver function tests) to confirm elevated bilirubin and rule out other liver diseases. In rare cases, genetic testing may be used for confirmation.
Generally, Gilbert’s syndrome does not require medical treatment because jaundice resolves spontaneously. However, doctors may prescribe “phenobarbital” if symptoms are bothersome to reduce bilirubin levels. To live with the condition, it is recommended to:
- Maintain a balanced diet and avoid skipping meals.
- Drink sufficient amounts of water and get enough sleep.
- Practice relaxation techniques such as yoga and meditation.
Medication Effects and Complications
The enzyme deficiency in this condition affects how the body eliminates certain medications, which may increase their toxicity or side effects. Some of the most prominent medications include:
- Irinotecan, used in cancer treatment.
- Certain protease inhibitors, such as “Indinavir,” used to treat HIV.
Additionally, the risk of developing gallstones may increase if this syndrome is combined with other conditions that impair the breakdown of red blood cells.
When Should You Visit a Doctor?
You should consult a doctor as soon as signs of jaundice (yellowing of the skin and eyes) appear, as there are many different causes for this condition. You should also inform any physician of the diagnosis before starting any new medications.
Frequently Asked Questions
What is Gilbert syndrome?
It is a harmless genetic condition that makes the liver unable to process bilirubin correctly, leading to elevated levels in the blood.
What causes Gilbert’s syndrome to flare up?
Flares are typically triggered by factors such as severe fasting, dehydration, psychological stress, illness, or extreme physical exertion.
Does this condition cause liver damage?
It is considered a harmless condition and does not usually lead to liver damage, and in most cases, it does not require treatment.
How can I control the symptoms?
By avoiding triggers such as extreme fasting, managing stress, and adhering to a healthy lifestyle that includes adequate sleep and hydration.
