Is Gilberts syndrome contagious?

Gilbert's syndrome is a benign, inherited genetic condition and is absolutely not contagious. It cannot be spread through touch, bodily fluids, or any other form of personal contact, as it is caused by a mutation in the UGT1A1 gene rather than an infectious pathogen.

Is Gilbert's syndrome contagious?

There is no risk of contagion associated with Gilbert's syndrome. Because it is a metabolic liver condition caused by a genetic variation, it is impossible to "catch" it from another person. Living with, touching, or sharing meals with someone who has Gilbert's syndrome poses zero health risk to you or your family. The condition simply means the liver processes bilirubin—a yellow pigment produced by the breakdown of red blood cells—slower than usual, leading to occasional mild jaundice.

What causes Gilbert's syndrome?

Gilbert's syndrome is a hereditary condition, not an infectious disease. It is caused by a mutation in the UGT1A1 gene, which provides instructions for making an enzyme that helps break down bilirubin in the liver. People with this syndrome have only about 30% of the normal enzyme activity. Because it is genetic, it is often passed down from parents to children, but it is not a "sickness" in the traditional sense; it is a lifelong variation in how the body functions.

Why is there confusion about contagion?

The confusion often stems from the primary symptom of Gilbert's syndrome: jaundice. Because jaundice—a yellowing of the skin and eyes—is commonly associated with infectious diseases like Hepatitis A, B, or C, people often mistakenly fear that someone with a "jaundiced appearance" is contagious. However, while Hepatitis is a viral infection, Gilbert's syndrome is a benign metabolic state that does not involve liver inflammation or infection. The stigma surrounding the appearance of jaundice is purely based on a misunderstanding of the underlying cause.

What are the common triggers for symptoms?

While the condition is not caused by external factors, certain stressors can make the mild jaundice more visible. Because the liver is already working at a reduced capacity, symptoms may appear during times of physical stress. Common triggers include:

• Dehydration: Not drinking enough fluids can cause bilirubin levels to rise.


• Fasting or skipping meals: Prolonged periods without food can temporarily increase bilirubin.


• Illness: Infections (like a common cold or flu) or surgery can act as a trigger.


• Menstruation: Hormonal fluctuations can sometimes lead to a mild increase in jaundice.


• Intense physical exertion: High-intensity exercise can occasionally trigger visible symptoms.

Living with Gilbert's syndrome

With 239 members in the DiseaseMaps.org community sharing their experiences, we know that many find comfort in knowing that this condition is generally harmless. It does not require specific medical treatment, and it does not shorten life expectancy or lead to liver failure. The focus is usually on maintaining a healthy lifestyle to avoid the triggers mentioned above.

Next steps

• Consult a gastroenterologist or hepatologist if you are concerned about persistent jaundice to rule out other, non-genetic conditions.


• Maintain a consistent eating and hydration schedule to minimize the appearance of symptoms.


• Join the DiseaseMaps.org community to connect with others who understand the reality of living with Gilbert's syndrome.


• Educate friends and family about the genetic nature of the condition to help reduce unnecessary stigma.
