Which are the symptoms of Gilberts syndrome?

Gilbert's syndrome is a common, benign liver condition characterized by the body’s inability to properly process bilirubin, leading to intermittent mild jaundice. While many people with Gilbert's syndrome remain asymptomatic, some individuals experience yellowing of the skin or eyes, particularly during periods of physical stress, illness, or fasting.

What are the primary symptoms of Gilbert's syndrome?

The hallmark of Gilbert's syndrome is the intermittent elevation of unconjugated bilirubin in the blood, a condition known as hyperbilirubinemia. For most of the 239 people with Gilbert's syndrome in our DiseaseMaps community, the condition is entirely asymptomatic and often discovered incidentally during routine blood work for unrelated issues. When symptoms do occur, they are typically mild and transient. The most recognizable symptom is a subtle yellowing of the skin and the whites of the eyes (jaundice). Because Gilbert's syndrome is a lifelong genetic condition, these symptoms do not usually progress to liver damage or chronic liver disease, as the liver's overall function remains normal.

What triggers symptoms in patients with Gilbert's syndrome?

Symptoms of Gilbert's syndrome are often triggered by external stressors that increase the body’s metabolic demand or interfere with bilirubin processing. Patients should monitor for yellowing during the following scenarios:

• Prolonged physical exertion or intense exercise.


• Dehydration or significant fasting/skipping meals.


• Acute illnesses, such as viral infections or the common flu.


• Periods of high emotional or psychological stress.


• Menstruation in women, which can sometimes correlate with transient increases in bilirubin levels.

How does Gilbert's syndrome affect daily quality of life?

For the vast majority of individuals, Gilbert's syndrome does not impact daily quality of life. However, a subset of patients reports non-specific symptoms such as fatigue, abdominal discomfort, or difficulty concentrating during periods of high bilirubin. Because these symptoms are subjective and often overlap with common daily stressors, it can be difficult to determine if they are directly caused by the elevated bilirubin or the underlying trigger (such as an infection). It is important to note that Gilbert's syndrome is considered a benign condition that does not require treatment or lifestyle restrictions beyond maintaining a healthy, balanced diet and staying hydrated.

When should I seek medical attention?

While Gilbert's syndrome is harmless, jaundice can also be a sign of more serious liver or gallbladder conditions. You should consult a physician if you experience jaundice for the first time or if it is accompanied by "red flag" symptoms, which are not characteristic of Gilbert's syndrome. Seek immediate medical evaluation if you notice:

• Dark, tea-colored urine or pale, clay-colored stools.


• Severe or persistent abdominal pain.


• Unexplained weight loss or loss of appetite.


• High fever or signs of systemic infection.


• Persistent jaundice that does not resolve after the stressor is removed.

Next steps

• Consult a primary care physician or a gastroenterologist to confirm that your elevated bilirubin is indeed due to Gilbert's syndrome and not another liver condition.


• Maintain a consistent eating schedule and stay well-hydrated to help minimize the frequency of jaundice.

• Keep a record of your blood test results to share with healthcare providers during future appointments.
