Jaundice in Adults: Causes, Symptoms, and When to Seek Medical Help

Jaundice is a condition in which the skin and the whites of the eyes turn yellow due to an increased level of bilirubin in the blood. Bilirubin is a yellow pigment produced naturally when the body breaks down old red blood cells. Under normal circumstances, the liver processes bilirubin and eliminates it through bile. When this process is disrupted, bilirubin accumulates in the bloodstream, resulting in jaundice.

Jaundice is not a disease itself; it is a sign of an underlying medical condition. In adults, it may occur due to liver disease, gallstones, bile duct obstruction, certain blood disorders, or, in some cases, pancreatic and biliary cancers. Identifying the underlying cause early is essential for appropriate treatment and prevention of complications.

What Are the Symptoms of Jaundice?

The symptoms of jaundice may develop gradually or appear suddenly, depending on the underlying cause. Common symptoms include:

Yellowing of the eyes and skin: The most characteristic sign of jaundice.
Dark-coloured urine: Urine may appear tea-coloured or dark brown.
Pale or clay-coloured stools: This may indicate reduced bile flow into the intestine.
Itching: Accumulation of bile-related substances can cause persistent itching.
Abdominal pain: Particularly in the upper right side of the abdomen.
Loss of appetite and nausea: These may occur with liver inflammation or biliary disease.
Fatigue and weakness: Common in several liver conditions.
Fever and chills: These may indicate an infection, including infection of the bile ducts.
Unexplained weight loss: This is particularly concerning when associated with progressive, painless jaundice.

Not every patient experiences all these symptoms. Sometimes, yellowing of the eyes may be the first noticeable sign.

What Causes Jaundice in Adults?

The causes of jaundice can be divided into three major categories according to where the problem occurs.

1. Liver-Related Causes

The liver plays a central role in processing bilirubin. Conditions that damage liver cells or interfere with their function can cause jaundice.

Common causes include:

Viral hepatitis, including hepatitis A, B, and E.
Alcohol-related liver disease.
Metabolic dysfunction-associated steatotic liver disease with significant liver injury.
Drug-induced liver injury.
Autoimmune hepatitis.
Advanced liver disease and cirrhosis.

The treatment depends on the specific condition and the severity of liver injury.

2. Obstruction of the Bile Ducts

Bile carries bilirubin from the liver to the intestine. If the bile ducts become blocked, bilirubin accumulates in the blood, resulting in obstructive jaundice.

Possible causes include:

Gallstones lodged in the common bile duct.
Benign bile duct strictures.
Inflammation or injury involving the bile ducts.
Tumours of the bile duct or gallbladder.
Pancreatic tumours that compress or obstruct the lower bile duct.

Patients may develop yellow eyes, dark urine, pale stools, and itching. Abdominal pain may or may not be present.

Obstructive jaundice requires prompt evaluation because some causes need urgent intervention.

3. Excessive Breakdown of Red Blood Cells

Red blood cells naturally break down as part of their life cycle. When they are destroyed more rapidly than normal, bilirubin production increases.

Possible causes include:

Haemolytic anaemia.
Certain inherited blood disorders.
Immune-mediated conditions.
Some infections and medication-related reactions.

In these situations, the liver may be unable to process the increased bilirubin load efficiently.

Another cause of mild, intermittent jaundice is Gilbert syndrome, an inherited condition that generally does not cause serious liver damage.

Can Jaundice Be a Sign of Gallstones or Pancreatic Cancer?

Yes. Jaundice can be an important warning sign of gallstones or an underlying pancreatic or biliary tumour.

A gallstone that enters and blocks the common bile duct may cause sudden jaundice, abdominal pain, dark urine, and pale stools. Depending on the clinical findings, treatment may involve endoscopic stone removal and subsequent management of the gallbladder.

In contrast, a tumour involving the head of the pancreas or bile duct may gradually obstruct the flow of bile. The patient may develop progressive yellowing of the eyes, itching, dark urine, pale stools, loss of appetite, and unexplained weight loss. Pain may be absent, particularly during the early stages.

These symptoms do not necessarily indicate cancer. However, new-onset, progressive, or painless jaundice in an adult should never be ignored, as timely investigation can influence treatment options and outcomes.

When Should You Seek Medical Help?

Any new onset of yellowing of the eyes or skin warrants prompt medical assessment, even when there is no pain.

Seek emergency medical care if jaundice is accompanied by:

Fever or chills with abdominal pain.
Severe or persistent abdominal pain.
Confusion, unusual drowsiness, or altered consciousness.
Repeated vomiting or inability to maintain hydration.
Bleeding or rapidly worsening general condition.

The combination of fever, jaundice, and upper abdominal pain may indicate acute cholangitis, a potentially life-threatening infection of the bile ducts that requires urgent treatment.

Medical evaluation is also particularly important when jaundice occurs alongside unexplained weight loss, persistently pale stools, dark urine, or persistent itching.

Do not wait for symptoms to become severe before consulting a doctor.

How Is Jaundice Diagnosed?

The primary objective of diagnosis is to determine the underlying cause rather than simply confirm the presence of jaundice.

1. Blood Tests

Initial investigations generally include:

Total and direct bilirubin.
Liver enzymes, including ALT and AST.
Alkaline phosphatase (ALP) and gamma-glutamyl transferase (GGT).
Complete blood count.
Albumin and prothrombin time/INR to assess aspects of liver function and clotting.

Additional tests may be required for viral hepatitis, haemolysis, autoimmune disease, or other suspected conditions.

2. Ultrasound of the Abdomen

Ultrasound is often the first imaging investigation when bile duct obstruction is suspected. It can help identify gallstones, dilated bile ducts, and certain liver abnormalities.

3. CT Scan or MRCP

Contrast-enhanced CT or magnetic resonance cholangiopancreatography (MRCP) may be recommended to assess the pancreas, bile ducts, suspected obstruction, or a possible tumour.

The choice of imaging depends on the blood test results and clinical findings.

4. ERCP When Treatment Is Needed

Endoscopic retrograde cholangiopancreatography (ERCP) allows specialists to treat selected bile duct problems, including removing obstructing stones, draining an infected bile duct, or inserting a stent.

ERCP is not routinely required for every patient with jaundice. It is generally used when there is a clear therapeutic indication or a specific diagnostic need.

How Is Jaundice Treated?

There is no single treatment for all types of jaundice. Management depends on the underlying cause.

Viral hepatitis: Treatment depends on the virus and severity. Some infections require supportive care, while others may require specific antiviral therapy.
Drug-induced liver injury: The suspected causative medicine may need to be stopped or changed under medical supervision.
Bile duct stones: ERCP may be required to remove the stones, followed by appropriate treatment of the gallbladder when indicated.
Bile duct obstruction due to a tumour: Treatment may include biliary drainage, stenting, surgery, or cancer-directed therapies, depending on the diagnosis and stage.
Haemolytic disorders: Treatment targets the underlying cause of excessive red blood cell destruction.
Severe liver disease: Specialist assessment is essential, and selected patients may require advanced liver support or evaluation for liver transplantation.

Patients should avoid alcohol and should not use unverified herbal remedies or supplements marketed as liver cleansers. Some of these products can cause additional liver injury. Prescribed medicines should not be discontinued without appropriate medical advice unless emergency clinicians direct otherwise.

Can Jaundice Be Prevented?

Not all causes of jaundice are preventable, but certain measures can reduce the risk of some underlying conditions.

Maintain good hygiene and consume safe food and drinking water to reduce the risk of hepatitis A and E.
Consider hepatitis A and B vaccination when medically appropriate.
Avoid excessive alcohol consumption.
Use prescription and over-the-counter medicines only as directed.
Maintain a healthy weight and manage diabetes and other metabolic risk factors.
Seek medical assessment for recurrent abdominal pain, gallstone symptoms, or unexplained weight loss.

Most importantly, do not rely on home remedies or dietary changes alone when yellowing of the eyes or skin develops.

Frequently Asked Questions About Jaundice

1. Is jaundice in adults dangerous?

Jaundice can range from a relatively harmless condition, such as Gilbert syndrome, to a medical emergency caused by severe hepatitis, bile duct obstruction, or infection. The underlying cause determines the severity and treatment required.

2. Is jaundice contagious?

Jaundice itself is not contagious. However, certain underlying infections, such as hepatitis A and E, can spread through contaminated food or water. Hepatitis B and C have different transmission routes.

3. How long does jaundice take to resolve?

Recovery depends on the cause. Some uncomplicated infections improve over several weeks, while jaundice due to bile duct obstruction or significant liver disease may persist until the underlying problem is treated. There is no universal recovery timeline.

4. Can jaundice occur without abdominal pain?

Yes. Liver disease and bile duct obstruction can cause painless jaundice. Progressive, painless jaundice, particularly when associated with weight loss, requires prompt investigation.

5. Which doctor should I consult for jaundice?

A qualified physician or gastroenterologist can initiate the evaluation. If bile duct obstruction, gallstone complications, or pancreatic and biliary tumours are suspected, assessment by a hepatobiliary specialist may be necessary.
