What syndrome causes high bilirubin levels?
The syndrome that causes high bilirubin levels is Gilbert syndrome.
Gilbert syndrome is a common and usually harmless liver condition characterized by elevated levels of bilirubin in the blood. Bilirubin is a yellowish pigment that forms when red blood cells break down. Normally, the liver processes bilirubin, converting it into a form that can be eliminated from the body.
Understanding Gilbert Syndrome and Bilirubin
In individuals with Gilbert syndrome, the body has a slightly modified gene inherited from parents. This gene typically controls an enzyme in the liver crucial for breaking down bilirubin. When this gene is ineffective, the body produces an insufficient amount of the enzyme. Consequently, bilirubin is not processed as efficiently, leading to an accumulation of excess bilirubin in the bloodstream.
This condition is often discovered incidentally during routine blood tests when mildly elevated bilirubin levels are noted. Unlike more severe liver conditions, Gilbert syndrome generally does not lead to serious health problems or require treatment.
Key characteristics of Gilbert syndrome include:
- Genetic Basis: It is an inherited condition, meaning it runs in families.
- Enzyme Deficiency: The core issue is a reduced activity of a specific liver enzyme (UDP-glucuronosyltransferase, or UGT1A1) that helps conjugate bilirubin.
- Intermittent Jaundice: While most individuals with Gilbert syndrome do not experience noticeable symptoms, some may have episodes of mild jaundice (yellowing of the skin or eyes), especially during periods of stress, illness, fasting, or vigorous exercise. These episodes are temporary and resolve on their own.
It's important to differentiate Gilbert syndrome from other, more serious causes of high bilirubin, which can indicate underlying liver disease or other health issues. However, when Gilbert syndrome is diagnosed, it typically means the liver is otherwise healthy and functioning normally, aside from its reduced ability to process bilirubin efficiently.
