How do I know if I have Gilberts syndrome?

Gilbert's syndrome is a common, benign liver condition characterized by a mild, fluctuating elevation of unconjugated bilirubin in the blood, often resulting in intermittent jaundice. It is typically diagnosed through routine blood panels during periods of physiological stress, fasting, or illness, and it generally requires no medical treatment as it does not cause permanent liver damage.

What are the early signs of Gilbert's syndrome?

For many, Gilbert's syndrome is completely asymptomatic and is only discovered incidentally during a routine blood test. However, when symptoms do occur, they are usually mild. The most recognized sign is a subtle yellowish tint to the skin or the whites of the eyes (jaundice). This often appears during specific "triggers" that place stress on the body, such as fasting, dehydration, intense physical exertion, lack of sleep, or during a bout of illness like the flu. Because Gilbert's syndrome affects how the liver processes bilirubin—a waste product from the breakdown of red blood cells—these stressful events can cause a temporary rise in bilirubin levels, making the jaundice more visible.

How can I self-assess for Gilbert's syndrome?

If you suspect you have Gilbert's syndrome, look for patterns rather than constant symptoms. Ask yourself if the yellowing of your eyes or skin correlates with times you have skipped meals, been significantly stressed, or experienced a viral infection. Unlike more serious liver conditions, Gilbert's syndrome is a genetic variation that does not cause chronic fatigue, abdominal pain, or dark urine in its typical presentation. If you are experiencing persistent or worsening symptoms, it is vital to remember that these are likely not attributable to Gilbert's syndrome alone and require a thorough clinical investigation.

Which tests should I discuss with my doctor?

To investigate Gilbert's syndrome, your physician will likely focus on liver function tests (LFTs). Common markers include:

• Serum Bilirubin Test: This measures the levels of unconjugated (indirect) bilirubin in your blood.


• Complete Blood Count (CBC): To ensure there is no underlying anemia or blood cell destruction causing the elevated bilirubin.


• Liver Enzyme Panel: To rule out other liver diseases, as Gilbert's syndrome typically presents with normal liver enzymes (ALT, AST, ALP).


• Genetic Testing: While not always necessary, a DNA test for the UGT1A1 gene mutation can confirm the diagnosis if blood work remains inconclusive.

When are symptoms a red flag for urgent care?

While Gilbert's syndrome is a harmless condition, jaundice can be a symptom of more serious medical issues. Seek immediate medical attention if you experience:

• Severe abdominal pain or tenderness.


• Persistent dark-colored urine or pale, clay-colored stools.


• Unexplained weight loss or loss of appetite.


• High fever or confusion accompanying the jaundice.

How do I advocate for myself during medical visits?

If your doctor dismisses your concerns, bring a copy of your blood test results and highlight the specific triggers that seem to worsen your jaundice. Mention that 239 members of the DiseaseMaps.org community have shared experiences with Gilbert's syndrome, which can help your physician understand your desire for clarity. If you feel unheard, request a referral to a hepatologist (a liver specialist) who can provide a definitive diagnosis and peace of mind.

Next steps

• Schedule an appointment with your primary care provider to discuss your bilirubin levels.


• Keep a symptom diary tracking your diet, sleep, and physical activity alongside any noticeable jaundice.


• Avoid prolonged fasting or extreme dehydration, which are known to trigger bilirubin spikes.


• Connect with the 239 individuals on DiseaseMaps.org to share experiences and coping strategies.
