Key facts
Jaundice at a glance.
The essentials, in plain English - what it is, the three broad categories, and how the split bilirubin points the way.
-
What it is
Yellow discolouration of the sclerae, skin and mucous membranes caused by a rise in circulating bilirubin.
-
Three broad types
Pre-hepatic (haemolysis), hepatic (liver injury) and post-hepatic (biliary obstruction) - the split guides everything.
-
Split bilirubin
Conjugated versus unconjugated fractions on the LFTs are the single most useful piece of the puzzle.
-
Obstructive picture
Pale stools, dark urine and pruritus point strongly at a blockage in the bile ducts.
-
Painless jaundice
A key red flag - malignancy of the pancreas, ampulla or bile ducts must be excluded urgently.
-
Neonatal jaundice
A distinct condition in newborns with its own pathway - covered separately on our infant jaundice guide.
Why this guide matters
A structured plan, not a wait-and-see.
Jaundice covers everything from Gilbert syndrome to acute liver failure. A calm, ordered plan makes sure serious causes are not missed.
-
Pre-hepatic - haemolytic
Unconjugated bilirubin from red-cell breakdown - haemolysis in G6PD deficiency (see /conditions/glucose-6-phosphate-dehydrogenase-g6pd-deficiency/), hereditary spherocytosis (see /conditions/hereditary-spherocytosis/), sickle cell disease (see /conditions/sickle-cell-disease/), thalassaemia, autoimmune haemolysis, HUS (see /conditions/hemolytic-uremic-syndrome/) or benign Gilbert syndrome.
-
Hepatic - liver injury
Mixed hyperbilirubinaemia from viral hepatitis, alcohol, drug injury, autoimmune hepatitis (see /conditions/autoimmune-hepatitis/), MASH, cirrhosis, Wilson disease or haemochromatosis (see /conditions/hemochromatosis/) - specialist commissioned.
-
Post-hepatic - obstructive
Conjugated bilirubin with pale stools, dark urine and pruritus - stones (see /conditions/gallstones/), strictures, cholangiocarcinoma (see /conditions/hilar-cholangiocarcinoma/), pancreatic cancer (see /conditions/pancreatic-cancer/), ampullary tumours, PSC and primary biliary cholangitis. Neonatal jaundice is separate (see /conditions/infant-jaundice/).

Typical timeline: bloods and ultrasound within days, MRCP and MDT within weeks.
Symptoms
What jaundice actually looks like.
Yellow eyes and skin are only the start - dark urine, pale stools and pruritus are just as important, and hint at where the problem sits.
-
Yellow sclerae and skin
The classic sign - visible first in the white of the eye, then in the skin as bilirubin rises further.
-
Dark urine
Cola-coloured urine is a hallmark of conjugated hyperbilirubinaemia and biliary obstruction.
-
Pale stools
Chalky, pale stools suggest that bile is not reaching the gut - a strong pointer to obstruction.
-
Pruritus
Persistent itching, worse at night, is common in cholestasis and can be the most distressing symptom.
-
Fatigue and weight loss
Non-specific but important - especially when painless and progressive alongside jaundice.
-
Hepatomegaly and splenomegaly
An enlarged liver or spleen points to hepatic or haemolytic causes and needs specialist assessment.
-
Ascites and variceal bleeding
Signs of decompensated liver disease - see our hepatic encephalopathy guide for the wider picture.
-
Red flag - painless jaundice
Painless progressive jaundice in an adult needs urgent specialist assessment to rule out malignancy.
Treatment
How jaundice is treated in the UK.
Treat the underlying cause first - then relieve any biliary obstruction, control pruritus and, where needed, consider transplantation.
-
Treat the underlying cause
Every plan starts with a diagnosis - haemolysis, hepatitis, gallstones and tumours all need different specialist pathways.
-
ERCP and biliary stenting
For stones, strictures and tumour obstruction - endoscopic decompression is specialist commissioned and often the first step.
-
Surgical resection
For resectable pancreatic, ampullary or hilar tumours - considered by a hepatopancreatobiliary MDT under specialist care.
-
Antivirals and immunosuppression
For viral hepatitis and autoimmune hepatitis - see our autoimmune hepatitis guide - under specialist hepatology oversight.
-
Pruritus control
Cholestyramine, rifampicin and naltrexone can all help itch in cholestatic jaundice - specialist-guided.
-
Liver transplantation
For end-stage liver disease and selected acute liver failure - see our liver transplant clinic for the pathway.
-
Haematology-led care
For haemolytic jaundice from G6PD deficiency, hereditary spherocytosis or sickle cell disease - specialist haematology input.
-
MDT and patient support
A hepatology or HPB MDT coordinates care and the British Liver Trust supports patients throughout treatment.

Red flags
When jaundice needs urgent attention.
Most causes are worked up over days to weeks. These are the situations that need same-day or same-week specialist care.
-
Painless progressive jaundice
Classical for pancreatic, ampullary or hilar cholangiocarcinoma - see our pancreatic cancer and hilar cholangiocarcinoma guides. Urgent specialist referral.
-
Acute liver failure
Rapidly rising bilirubin with encephalopathy and coagulopathy - see our fulminant liver failure guide - is a specialist-commissioned emergency.
-
Ascending cholangitis
Fever, jaundice and right upper quadrant pain - Charcot triad - needs immediate admission, antibiotics and specialist biliary drainage.
-
Hepatic encephalopathy
Confusion, drowsiness or asterixis in a jaundiced patient signals decompensation and needs urgent hepatology review.
-
Suspected paracetamol overdose
Even a modest overdose can precipitate acute liver failure - a specialist toxicology and hepatology emergency.
-
Haemolytic crisis
Sudden severe jaundice with anaemia and dark urine - especially in known G6PD deficiency or sickle cell disease - needs urgent haematology care.
-
Wilson disease in a young adult
Unexplained hepatitis and neuropsychiatric change under 40 - a specialist-commissioned Wilson screen is essential.
-
Iron overload
A very high ferritin with transferrin saturation raises the possibility of haemochromatosis - see our hemochromatosis guide - and needs specialist input.
-
Pregnancy-related jaundice
HELLP syndrome, acute fatty liver of pregnancy and intrahepatic cholestasis all need immediate obstetric and hepatology assessment.
Living with it
Manageable, once the cause is clear.
Four things that make the biggest difference day to day - treating the underlying driver, cutting alcohol, controlling itch and keeping follow-up.
A quiet reminder
Yellow eyes deserve a plan, not a wait.
New jaundice in an adult is always worth investigating - the sooner the cause is clear, the sooner treatment can begin.
- 01 Cause
Treat the driver
Jaundice is a signal, not a disease - the plan follows the cause, whether that is stones, hepatitis, haemolysis or a tumour.
- 02 Alcohol
Alcohol matters
Whatever the cause, cutting or stopping alcohol reduces further liver injury and helps recovery.
- 03 Itch
Treat the itch early
Cholestatic pruritus is exhausting - cholestyramine, rifampicin or naltrexone can transform sleep and mood.
- 04 Follow-up
Keep the follow-up
Repeat LFTs, imaging and MDT review under specialist care are what catch relapse and recurrence early.
Frequently asked
Everything we get asked about jaundice.
Quick answers on the three types, split bilirubin, painless jaundice and how newborn jaundice differs.
-
What is jaundice?
Jaundice is a yellow discolouration of the sclerae, skin and mucous membranes caused by excess bilirubin in the blood. It is a sign of an underlying problem in the red cells, the liver or the bile ducts and always deserves prompt medical assessment.
-
What are the three main causes of jaundice?
Pre-hepatic jaundice comes from excess red cell breakdown - haemolysis. Hepatic jaundice comes from liver injury - viral hepatitis, alcohol, drugs, autoimmune hepatitis, MASH or cirrhosis. Post-hepatic jaundice comes from a blockage in the bile ducts, most often gallstones or a tumour.
-
Why do stools go pale and urine go dark?
When the bile ducts are blocked, conjugated bilirubin cannot reach the gut, so stools lose their normal brown colour and become chalky. Bilirubin is instead excreted through the kidneys, which turns the urine dark. Together with pruritus, this pattern is a strong pointer to obstructive jaundice.
-
Is painless jaundice always serious?
Painless, progressive jaundice in an adult is a red flag for malignancy of the pancreas, ampulla or bile ducts and needs urgent specialist assessment. Painful jaundice, especially with fever, more often points to gallstones or ascending cholangitis - also urgent, but usually a different pathway.
-
What tests are used to work out the cause?
Split bilirubin and full LFTs, a haemolysis screen, viral and autoimmune serology, and iron, copper and alpha-1 antitrypsin studies all sit alongside imaging. Ultrasound is usually first, followed by MRCP, CT or ERCP where indicated - all specialist commissioned.
-
Is neonatal jaundice the same condition?
No - jaundice in newborns has its own physiology, causes and pathway. It is common, often physiological and usually resolves with phototherapy, but it needs specific assessment. See our separate infant jaundice guide for the full picture.
