Key points
- Jaundice is a sign, not a disease. The treatment depends entirely on the cause.
- Painless jaundice with itching, pale stools and weight loss in an adult should be investigated for a blocked bile duct or cancer without delay.
- Jaundice with confusion, drowsiness or bleeding can mean acute liver failure — this needs hospital care the same day.
- Most causes are found with blood tests and an ultrasound; some need a CT, MRCP or endoscopy.
What is jaundice?
Bilirubin is a yellow pigment made when old red blood cells are broken down. The liver collects it, processes it and sends it out into the bile, which drains through the bile ducts into the intestine. Jaundice appears when any step in that chain fails and bilirubin backs up into the blood — usually first noticed in the whites of the eyes.
Doctors group the causes by where the chain breaks: before the liver (too much bilirubin being made), inside the liver (the liver cells cannot process it), or after the liver (the bile cannot drain). That grouping is what the tests are designed to answer.
Common causes of jaundice in adults
| Where the problem is | Common causes | Typical clues |
|---|---|---|
| Inside the liver | Viral hepatitis (A, B, C, E), alcohol-related hepatitis, cirrhosis, drug or herbal-medicine injury, acute liver failure | Fever or loss of appetite before the yellowness, alcohol history, new medicines, known liver disease |
| Bile ducts blocked by stones | Gallstones that slip into the bile duct (choledocholithiasis), cholangitis | Pain in the upper right abdomen, fever with chills, jaundice that comes and goes |
| Bile ducts blocked by a growth | Bile duct cancer, pancreatic cancer, gallbladder cancer, periampullary tumours | Painless, steadily deepening jaundice, severe itching, pale stools, dark urine, weight loss |
| Before the liver | Haemolysis (red cells breaking down), Gilbert's syndrome | Mild yellowness, normal liver enzymes, often harmless (Gilbert's) |
In eastern India, gallstone disease and gallbladder cancer are both more common than in many other regions, so a blocked bile duct is always on the list when an adult in Kolkata develops jaundice.
When jaundice is an emergency
Go to hospital the same day if jaundice comes with:
confusion, unusual sleepiness or change in behaviour; vomiting blood or passing black stools; high fever with shivering; severe abdominal pain; or a rapidly swelling abdomen. These can signal acute liver failure, bleeding from varices or an infected blocked bile duct (cholangitis).
Painless jaundice is not an emergency in the same way, but it should never be watched at home. When an adult turns yellow without pain — especially with itching, clay-coloured stools and weight loss — a blockage from a tumour must be ruled out quickly, because an operable cancer can become inoperable within weeks.
How the cause is found
- 1
Blood tests
Liver function tests show whether the pattern is liver-cell injury or blocked drainage. Hepatitis markers, blood counts and clotting (INR) are checked at the same time.
- 2
Ultrasound of the abdomen
The first scan. It shows whether the bile ducts are dilated (suggesting a blockage), gallstones, and the texture of the liver.
- 3
CT scan or MRCP
If the ducts are blocked, a contrast CT or MRCP (an MRI of the bile ducts) shows where and why, and whether a tumour can be removed.
- 4
Endoscopy (ERCP or EUS) when needed
An endoscope can remove duct stones, place a stent to relieve the jaundice, or take a biopsy. For a tumour that may be operable, the surgeon should see the scans before a stent is placed where possible.
Treatment depends on the cause
- Viral or drug-induced hepatitis: usually supportive care and stopping the offending medicine; most people recover, but a few progress to liver failure and need close monitoring.
- Duct stones: removed by ERCP, followed by removal of the gallbladder to stop them coming back.
- Tumours blocking the bile duct: assessed by an HPB surgeon for removal — for example a Whipple operation for tumours at the head of the pancreas or a liver and bile duct resection for cholangiocarcinoma.
- Jaundice from end-stage liver disease: a sign that the liver is failing; the question becomes whether the patient needs a liver transplant evaluation.
When to see a liver and HPB surgeon
A physician or gastroenterologist manages most hepatitis. You should see a liver transplant and HPB surgeon when scans show a blocked bile duct from a mass, when a tumour of the liver, gallbladder, bile duct or pancreas is suspected, or when jaundice is part of worsening cirrhosis or liver failure.
Dr Bappaditya Har reviews reports on WhatsApp before the first visit when families are travelling to Kolkata, so the right scans are done in the right order.
Frequently asked questions
Is jaundice in adults serious?
It always needs a cause. Many cases are due to viral hepatitis and settle, but jaundice can also be the first sign of a blocked bile duct, cancer or liver failure, so it should be investigated promptly rather than treated with home remedies.
What does painless jaundice mean?
Painless, steadily worsening jaundice in an adult — especially with itching, pale stools and weight loss — raises concern for a tumour blocking the bile duct, such as pancreatic, bile duct or gallbladder cancer. It needs a CT or MRCP soon.
Which test finds the cause of jaundice?
Liver function tests and an abdominal ultrasound are the first steps. A CT scan or MRCP is added when the bile ducts are dilated or a mass is suspected.
Can jaundice be treated with herbal medicine?
No herbal remedy treats the causes of jaundice, and some herbal and indigenous medicines are themselves a known cause of liver injury. Delay can let an operable condition progress.
When is a liver transplant needed for jaundice?
When jaundice is caused by liver failure — acute liver failure or end-stage cirrhosis — rather than a blockage. A transplant team assesses this with blood tests, scores such as MELD, and imaging. See liver transplant evaluation.
