hyperbilirubinemia
RareTechnical/Scientific
Definition
Meaning
An excessive level of bilirubin in the blood.
A medical condition characterized by an abnormally high concentration of bilirubin in the bloodstream, often leading to jaundice. It can be caused by increased bilirubin production (e.g., hemolysis), impaired liver uptake or conjugation, or bile duct obstruction.
Linguistics
Semantic Notes
This term is primarily used within medical contexts and is not a part of everyday vocabulary. It is a pathological diagnosis, not a symptom (the symptom is jaundice). It can be further classified by the type of bilirubin elevated (conjugated or unconjugated).

Examples
By Part of Speech
adjective
British English
- The hyperbilirubinemic infant required phototherapy.
- A hyperbilirubinemic state was confirmed by the lab.
American English
- The hyperbilirubinemic newborn needed light treatment.
- Hyperbilirubinemic bloodwork results were concerning.
Examples
By CEFR Level
- The baby had yellow skin, called jaundice, because of a problem in the blood.
- Newborn babies sometimes get jaundice, which means they have too much bilirubin.
- The doctor explained that the infant's jaundice was due to neonatal hyperbilirubinemia, requiring treatment under special lights.
- The pathogenesis of unconjugated hyperbilirubinemia often involves either increased hemolysis or a deficiency in the UDP-glucuronosyltransferase enzyme.
Learning
Memory Aids
Mnemonic
Think: HYPER (too much) + BILI (bile) + RUBIN (red) + EMIA (in the blood) = Too much red bile pigment in the blood.
Conceptual Metaphor
A FLOOD/CONGESTION metaphor: Bilirubin floods or congests the bloodstream, overwhelming the body's processing systems.

Common Pitfalls
Translation Traps (for Russian speakers)
- Do not confuse with 'гепатит' (hepatitis). Hyperbilirubinemia is a lab finding, hepatitis is an inflammation of the liver which can cause it.
- The Russian term 'гипербилирубинемия' is a direct calque and is used identically in medical contexts.
Common Mistakes
- Pronouncing it as 'hyper-billy-ruben-emia'. Correct stress is crucial.
- Using it interchangeably with 'jaundice' in technical writing; jaundice is the visible sign, hyperbilirubinemia is the biochemical cause.
- Misspelling: 'hyperbillirubinemia' (double 'l') or 'hyperbilirubinaemia' (UK spelling is not standard for this term).

FAQ
Frequently Asked Questions
No. Hyperbilirubinemia is the biochemical condition of having too much bilirubin in the blood. Jaundice is the clinical sign (yellowing of skin/eyes) that often results from it.
It can be. Mild hyperbilirubinemia in newborns is common and often harmless, but severe cases, especially if untreated, can lead to kernicterus, a form of brain damage.
Treatment depends on the cause and severity. Common treatments include phototherapy (special blue lights) for newborns, addressing the underlying cause (e.g., treating an infection), or, in rare cases, exchange transfusion.
Yes. While most associated with newborns, adults can develop it from conditions like Gilbert's syndrome, liver disease (hepatitis, cirrhosis), gallstones, or hemolytic anemias.
