Jaundice

Introduction

Jaundice (icterus) is yellowing of the skin, the whites of the eyes (sclera), and mucous membranes caused by high bilirubin in the blood (hyperbilirubinemia). Bilirubin is produced when red blood cells break down; the liver normally processes it and sends it into bile for excretion. When production rises, liver processing fails, or bile drainage is blocked, bilirubin builds up and tissues turn yellow.

Clinically important jaundice usually appears when serum bilirubin rises above about 2–3 mg/dL. Scleral icterus is often noticed early because the eye’s connective tissue binds bilirubin readily. Jaundice is a sign, not a single disease—the underlying pre-hepatic, hepatic, or post-hepatic cause must be found.

Unconjugated (indirect) bilirubin rises with haemolysis, some inherited enzyme defects, and many newborn patterns. Conjugated (direct) bilirubin rises with hepatitis, cirrhosis, bile-duct obstruction, and some drugs. Adults more often present with viral hepatitis, alcohol-related liver disease, gallstones, pancreatic or biliary malignancy, or medication injury—distinct from the common physiological jaundice of healthy newborns (covered separately).

Treatment always targets the cause: antivirals for viral hepatitis, stone removal or ERCP for obstruction, support for haemolysis, or transplant in selected end-stage liver disease. This page focuses on general and adult-oriented jaundice evaluation; newborn-specific care is discussed on the neonatal jaundice page.

Overview

Jaundice reflects disrupted bilirubin production, conjugation, transport, or excretion. Classifying the problem as pre-hepatic, hepatocellular, or post-hepatic (obstructive) guides urgent tests and treatment.

Accompanying dark urine, pale clay-coloured stools, and itching suggest conjugated hyperbilirubinemia and possible cholestasis or biliary obstruction. Painless progressive jaundice raises concern for malignant biliary blockage.

Most cases improve when the driver is treated. Very high bilirubin with liver failure, sepsis, or complete biliary obstruction can be life-threatening and needs urgent hospital care.

• Yellow skin/eyes from elevated bilirubin—not a diagnosis by itself
• Normal total bilirubin usually <1.0 mg/dL; jaundice often >2–3 mg/dL
• Three big buckets: haemolysis (pre-hepatic), liver cell injury, bile-flow blockage
• Dark urine + pale stools + itch → think cholestasis/obstruction
• Pseudo-jaundice from excess carotene yellows skin but not the sclera
• Adult work-up differs from routine newborn physiological jaundice

What happens in the body

Haem from red cells becomes unconjugated bilirubin, carried on albumin to the liver. Hepatocytes conjugate bilirubin and export it into bile ducts toward the intestine. Excess production, failing hepatocytes, or blocked ducts raise blood levels and stain tissues.

Pre-hepatic causes overload the system with unconjugated pigment (haemolysis). Hepatocellular disease interrupts uptake, conjugation, or excretion inside the liver. Post-hepatic obstruction stops conjugated bilirubin from reaching the gut, so stools pale and urine darkens with bilirubin.

• RBC breakdown → bilirubin → liver conjugation → bile excretion
• Pre-hepatic: too much bilirubin production (e.g., malaria, sickle crisis, thalassaemia)
• Hepatic: hepatitis, alcohol-related disease, toxins, cirrhosis, infiltrative cancer
• Post-hepatic: gallstones, cholangitis, pancreatic/biliary tumours, strictures
• Inherited patterns: Gilbert, Crigler–Najjar, Dubin–Johnson (specialist context)

Signs and symptoms

Yellow colour is the hallmark. Other features depend on the cause:

• Yellow skin and yellow sclera, often starting at the head and progressing downward
• Dark brown urine
• Pale or clay-coloured stools (especially obstructive/cholestatic jaundice)
• Itching (pruritus), sometimes with scratch marks
• Fatigue, poor appetite, nausea, or vomiting
• Abdominal pain or discomfort (gallstones, hepatitis, pancreatitis)
• Fever (infection, cholangitis, viral illness)
• Weight loss (consider malignancy or chronic liver disease)
• Enlarged spleen in some haemolytic states
• In chronic liver disease: swelling of legs/abdomen, palmar redness, or other chronic signs
• Flu-like prodrome before yellowing in some viral hepatitis cases

Causes and risk factors

Think in anatomic categories and risk exposures:

• Haemolysis: sickle cell crisis, malaria, thalassaemia, certain drugs/toxins
• Viral hepatitis (A, B, C, E) and other liver infections
• Alcohol-related liver disease and cirrhosis
• Drug-induced liver injury (including paracetamol overdose) and industrial solvents
• Gallstones in the common bile duct; cholangitis; pancreatitis
• Cancers of the pancreas, bile duct, or gallbladder causing obstruction
• Inherited disorders (Gilbert, Crigler–Najjar, Dubin–Johnson) and autoimmune hepatitis
• Risk contexts: unsafe injections, unprotected sex, transfusions in the past, travel to hepatitis/malaria regions, heavy alcohol use
• Pregnancy-related cholestasis (specialist obstetric care)
• Carotene excess causing pseudo-jaundice (skin yellow, sclera spared)

Diagnosis and evaluation

Confirm jaundice, quantify bilirubin fractions, then locate the mechanism:

• History: alcohol, medicines/herbals, travel, transfusions, sexual/injection risk, abdominal pain, weight loss, prior liver disease
• Exam: scleral icterus, liver/spleen size, ascites, fever, excoriations, painless vs tender abdomen
• Serum total and direct/indirect bilirubin
• Liver enzymes (ALT, AST, ALP, GGT) to separate hepatocellular vs cholestatic patterns
• CBC for anaemia/haemolysis clues; viral hepatitis serologies as indicated
• Urine urobilinogen/bilirubin patterns supporting pre-/intra-/post-hepatic categories
• Ultrasound first for ducts and gallbladder; CT/MRI/MRCP when needed
• ERCP for diagnosis and therapy in selected extrahepatic obstruction
• Liver biopsy in selected unclear chronic or infiltrative disease

Treatment and management

Treat the driver of hyperbilirubinemia—do not chase yellow colour alone:

• Supportive care: rest as needed, hydration, nutrition; stop alcohol and unnecessary hepatotoxic drugs
• Antivirals for appropriate chronic or selected acute viral hepatitis—specialist directed
• Treat infections such as malaria or leptospirosis per local protocols
• Steroids or other immune therapy only for confirmed autoimmune haemolysis or autoimmune hepatitis under specialist care
• Transfusion or disease-specific therapy for severe haemolytic anaemia
• ERCP with stone extraction/stenting for many extrahepatic biliary obstructions
• Cholecystectomy or biliary surgery when indicated after acute issues settle
• Liver resection or transplant evaluation in selected severe or malignant disease
• Itch management and cholestasis therapies as advised by hepatology
• Newborn phototherapy/exchange belong to neonatal protocols—see neonatal jaundice page for infant-focused care

Prevention, self-care, and lifestyle

Not every condition is fully preventable, but the steps below may lower risk or recurrence:

• Limit or avoid alcohol; never combine heavy drinking with high-dose paracetamol
• Hepatitis vaccination where recommended; safer sex and no sharing of needles
• Food and water hygiene when travelling; malaria precautions in endemic areas
• Occupational protection from hepatotoxic chemicals
• Medication safety: follow dosing, disclose all supplements to clinicians
• Genetic counselling for families with rare severe inherited bilirubin disorders
• Maintain a balanced diet and healthy weight to reduce fatty-liver risk

Possible complications

Delay, missed care, or unsafe self-medication can raise the chance of complications in some cases:

• Acute liver failure
• Sepsis, especially with ascending cholangitis
• Chronic liver disease and portal hypertension
• Malnutrition and vitamin deficiencies with prolonged cholestasis
• Severe intractable itching and sleep disruption
• Kernicterus is mainly a newborn brain-bilirubin injury—adults rarely face that pathway, but untreated severe adult liver disease still carries high mortality
• Missed malignant obstruction with delayed cancer care

When to see a doctor or seek emergency care

Seek prompt medical advice or emergency care if any of the following apply—it is safer not to wait and see:

• New yellow eyes/skin, dark urine, or pale stools
• Jaundice with fever, severe abdominal pain, or confusion
• Jaundice after starting a new medicine or after paracetamol overdose concern
• Known liver disease with worsening yellowing, swelling, or bleeding
• Painless progressive jaundice and weight loss—urgent evaluation for obstruction/cancer
• Pregnancy with itching and abnormal liver tests
• Any rapid mental change, vomiting blood, or black stools—emergency care

Living with the condition

If you have chronic liver or biliary disease, keep a medication list, avoid alcohol, and attend scheduled lab and imaging follow-up. Report new itching, swelling, or confusion early.

Ask your clinician which painkillers are safer for your liver and how to handle infections. Vaccinate against hepatitis A/B if not immune and recommended.

For intermittent Gilbert-type mild unconjugated rises, reassurance and avoiding prolonged fasting may be enough—confirm the label with labs rather than self-diagnosis.

Frequently asked questions

Can jaundice be cured?

Often yes, when the cause is reversible—infection, drug injury, or a removable bile-duct stone. Chronic liver disease or cancer needs ongoing specialist management; transplant is an option in selected end-stage cases.

Is jaundice always serious?

Mild transient rises can be less urgent, but jaundice with fever, pain, confusion, bleeding, or very high bilirubin needs prompt care. It always deserves a cause work-up.

How is adult jaundice different from newborn jaundice?

Many newborns have temporary immature-liver jaundice that resolves with feeding and, if needed, phototherapy. Adult jaundice more often signals hepatitis, obstruction, haemolysis, or toxins and needs a different diagnostic pathway.

Do yellow palms from carrots mean liver disease?

Excess carotene can yellow the skin (pseudo-jaundice) while the sclera stay white. True jaundice usually colours the eyes as well—get checked if unsure.

Which tests come first?

Bilirubin fractions, liver enzymes, blood count, and often abdominal ultrasound are early steps; further scans or ERCP depend on those results.

Important caution

Jaundice is a visible warning that bilirubin handling has failed somewhere along the pathway. Timely classification into haemolysis, liver injury, or obstruction—and treatment of that cause—matters far more than skin colour alone.
