Yellowing of the whites of the eyes (sclera) or the skin is often linked to elevated levels of a substance called bilirubin in the blood. This can occur at any age and has many causes, including problems with the liver or bile ducts, faster breakdown of red blood cells (hemolysis), certain infections, or reactions to medications. Below is a concise guide to common causes, which specialists may be involved, and warning signs that suggest the need for prompt medical evaluation.
How jaundice develops and typical causes
Jaundice usually reflects increased bilirubin from one of three processes: excess red blood cell breakdown (hemolysis), reduced liver processing (hepatocellular injury such as viral hepatitis or toxin-related injury), or blocked bile flow (obstruction from gallstones or masses). In newborns, mechanisms and timelines differ and are assessed separately. Some medications and infections can also raise bilirubin levels.
Signs that require urgent attention
Mild, isolated yellowing may be benign, but certain accompanying signs suggest a more serious problem and warrant urgent evaluation: fever with chills, severe abdominal pain (especially in the upper right side), confusion or marked sleepiness, unusual bleeding or bruising, very dark urine, very pale or clay-colored stools, and sudden, severe weakness. If these occur, contact emergency medical services or go to an emergency department.
Who evaluates jaundice and common tests
Initial assessment often starts with a primary care physician or internal medicine clinic. Depending on findings, specialists involved can include Gastroenterology/Hepatology (liver and bile duct disorders), Infectious Diseases (suspected infections), Hematology (if hemolysis is suspected) and Ophthalmology for focused eye examination when needed. Evaluation commonly uses blood tests (liver function tests, bilirubin fractions, complete blood count), abdominal ultrasound, and, if indicated, CT or MRI and targeted blood tests. The exact tests depend on clinical findings.
Prevention and general lifestyle advice
Preventive measures depend on the cause but general recommendations include limiting alcohol intake, avoiding unprescribed medications or supplements that may affect the liver, staying up to date with hepatitis A and B vaccinations when appropriate, and practicing hygiene and safer sex to reduce infection risk. Share your full medication and transfusion history with clinicians. These are general measures and not a substitute for individualized medical assessment.
