Medicines for Gilbert's syndrome

What it is

Gilbert's syndrome is a common, harmless, inherited condition affecting how the liver processes bilirubin — a yellow substance made when old red blood cells are broken down. In Gilbert's syndrome, the liver processes bilirubin slightly less efficiently than usual, so the bilirubin level in the blood can rise a little, particularly at certain times. The main (and often only) feature is occasional, mild jaundice — a slight yellow tinge to the whites of the eyes and sometimes the skin — which tends to come and go, and is typically brought on by things that transiently raise bilirubin, such as illness or infection, fasting or not eating enough, dehydration, stress, tiredness, physical exertion, or during a period. Some people also report vague symptoms like tiredness, though these are not clearly caused by the condition. Crucially, Gilbert's syndrome is not a disease and does not damage the liver — the liver is otherwise completely normal — and it does not cause any long-term harm. It is very common, often runs in families, and is frequently discovered by chance when a blood test shows a mildly raised bilirubin with otherwise normal liver tests.

How it is treated

The most important part of managing Gilbert's syndrome is recognising it and providing reassurance — understanding that it is a harmless, lifelong condition that needs no treatment and does not damage the liver or shorten life. It is usually identified from the typical pattern: a mildly raised bilirubin (which rises further at times of stress, illness or fasting) with otherwise normal liver blood tests and no signs of liver disease or excessive red cell breakdown; occasionally further tests are done to confirm it and exclude other causes. Once confirmed, no treatment or monitoring of the liver is needed, and people can be reassured that episodes of mild jaundice are harmless and simply reflect the condition, often triggered by being unwell, not eating, or being run down. There is one practical point: because bilirubin is handled by the same liver pathway that processes some medicines, people with Gilbert's syndrome can occasionally be more sensitive to a few specific drugs, so it is worth mentioning the condition to doctors. Otherwise, no special precautions or dietary restrictions are needed. The reassuring message is that Gilbert's syndrome is a common, benign quirk of bilirubin processing that causes only harmless, fluctuating mild jaundice and needs nothing more than reassurance.
