Jaundice in Adults: Understanding the Causes and When to See a Doctor

Have you noticed yellowing of the eyes or skin, unusually dark urine, or persistent tiredness? These symptoms may indicate jaundice, a condition that can develop when bilirubin builds up in the blood.

Jaundice is not a disease on its own. It is a sign of an underlying problem that may involve the liver, gallbladder, bile ducts, or the breakdown of red blood cells. While some causes are temporary and treatable, others may require urgent medical attention.

Understanding the causes and warning signs of jaundice in adults can help you recognise when to seek medical care and why identifying the underlying cause is important.

What Is Jaundice?

Jaundice is the yellow discolouration of the skin, the whites of the eyes, and sometimes the mucous membranes. It occurs when bilirubin, a yellow pigment produced during the normal breakdown of red blood cells, accumulates in the body.

Normally, the liver processes bilirubin and helps remove it from the body through bile, which eventually passes into the digestive tract. If bilirubin production increases, the liver cannot process it properly, or bile flow becomes blocked, bilirubin levels may rise.

Jaundice can occur in adults of any age. Its severity and associated symptoms depend on the underlying cause, making medical evaluation important.

Common Causes of Jaundice in Adults

1. Liver Infections, Including Viral Hepatitis

Viral hepatitis is an important cause of jaundice. Hepatitis A, B, C, and E are infections that affect the liver, although their routes of transmission and clinical courses differ.

Hepatitis A and E are commonly transmitted through contaminated food or water. Hepatitis B and C can spread through infected blood and certain other bodily fluids, with hepatitis B also capable of spreading from an infected mother to her baby.

When the liver becomes inflamed, its ability to process bilirubin may be affected. Symptoms can include yellowing of the eyes, dark urine, fatigue, nausea, reduced appetite, and abdominal discomfort.

What to do: Seek medical evaluation if jaundice develops, particularly if it is accompanied by fever, vomiting, or significant weakness. Treatment and preventive measures depend on the type of hepatitis and the patient's condition.

2. Fatty Liver Disease and Liver Inflammation

Fatty liver disease involves the accumulation of excess fat in the liver. Metabolic dysfunction-associated steatotic liver disease (MASLD) is associated with factors such as obesity, type 2 diabetes, abnormal blood lipids, and other metabolic conditions.

Fatty liver disease does not usually cause jaundice in its early stages. However, advanced liver damage or severe inflammation may impair liver function and lead to jaundice.

Alcohol-related liver disease can also cause inflammation and damage that may affect bilirubin processing.

What to do: People with known liver disease should follow their doctor's advice regarding monitoring, nutrition, physical activity, alcohol avoidance when indicated, and management of associated medical conditions. New jaundice requires prompt assessment rather than assuming it is due to fatty liver alone.

3. Gallstones and Bile Duct Blockage

Bile helps the body digest fats and carries bilirubin away from the liver. Gallstones may sometimes move from the gallbladder into the common bile duct and obstruct the normal flow of bile.

When this happens, bilirubin can accumulate in the blood, causing jaundice. Other symptoms may include pain in the upper right abdomen, dark urine, pale stools, nausea, and itching.

A blocked bile duct can sometimes become infected, leading to a serious condition called cholangitis.

What to do: Jaundice accompanied by fever, chills, or significant upper abdominal pain requires urgent medical attention. Treatment may involve removing the obstruction through an appropriate endoscopic or surgical procedure, depending on the cause.

4. Alcohol-Related Liver Disease

Regular heavy alcohol consumption can damage liver cells over time. In some people, this leads to alcohol-associated hepatitis, cirrhosis, or other complications that interfere with normal liver function.

Jaundice may develop alongside fatigue, nausea, loss of appetite, abdominal swelling, or fluid accumulation. The severity of symptoms varies depending on the extent of liver damage.

What to do: If jaundice develops in someone who consumes alcohol, prompt medical evaluation is essential. Avoid alcohol and seek medical guidance. People with alcohol dependence should obtain professional help because suddenly stopping alcohol can sometimes cause dangerous withdrawal symptoms.

5. Certain Medicines and Supplements

Some prescription medicines, over-the-counter medications, herbal products, and dietary supplements can cause liver injury in susceptible individuals.

The risk depends on the substance, dose, duration of use, interactions, and individual health factors. Excessive use of certain medicines, including paracetamol, can cause severe liver damage.

What to do: Inform your doctor about all medicines and supplements you use. Do not exceed recommended medication doses. If jaundice develops after starting a medicine or supplement, seek prompt medical advice rather than stopping essential prescription treatment without guidance.

6. Increased Breakdown of Red Blood Cells

Jaundice can also occur when red blood cells break down more rapidly than usual, a process known as haemolysis. This produces bilirubin faster than the liver may be able to process it.

Possible causes include certain blood disorders, immune-related conditions, and reactions to some medicines.

Symptoms may include yellowing of the eyes, fatigue, pale appearance, and sometimes dark urine, depending on the underlying condition.

What to do: A doctor may recommend blood tests to assess bilirubin levels, red blood cell counts, and signs of haemolysis. Treatment depends on the specific cause.

7. Other Liver and Bile Duct Conditions

Less common causes of jaundice include autoimmune liver diseases, inherited disorders affecting bilirubin processing, and narrowing or other diseases of the bile ducts.

In some cases, a growth involving the pancreas, liver, gallbladder, or bile ducts may obstruct bile flow. Persistent or painless jaundice, particularly when accompanied by unexplained weight loss, requires prompt investigation.

These symptoms do not automatically mean cancer is present, but they should not be ignored.

Common Symptoms of Jaundice in Adults

Yellowing of the eyes is often one of the earliest noticeable signs of jaundice. Other symptoms may vary according to the underlying condition.

Common signs include:

• Yellowing of the skin and whites of the eyes.

• Dark or tea-coloured urine.

• Pale or clay-coloured stools.

• Itching of the skin.

• Unusual tiredness or weakness.

• Reduced appetite, nausea, or vomiting.

• Abdominal pain or discomfort.

• Fever or chills in certain infections.

Not everyone experiences all these symptoms. The colour of the skin alone also cannot determine the severity of the underlying problem.

When Should You See a Doctor?

New jaundice in an adult requires prompt medical assessment, even if there is no pain. Do not wait for the yellowing to disappear on its own.

Seek urgent medical care if jaundice is accompanied by:

• Fever or chills with abdominal pain.

• Severe abdominal pain or repeated vomiting.

• Confusion, unusual drowsiness, or changes in behaviour.

• Bleeding, fainting, or marked weakness.

• Rapidly worsening yellowing or abdominal swelling.

These symptoms may indicate a serious liver problem, bile duct infection, or another condition requiring emergency treatment.

How Is Jaundice Diagnosed?

A gastroenterologist or other qualified doctor will assess your symptoms, medical history, medication use, alcohol consumption, and possible exposure to infections.

Investigations may include:

Blood tests: Bilirubin levels and liver enzymes help assess liver injury and bile flow. Additional tests may evaluate blood cell breakdown, clotting function, and viral hepatitis.

Ultrasound: An abdominal ultrasound can help identify gallstones, bile duct dilation, and certain structural changes in the liver or nearby organs.

Additional imaging: Depending on the initial findings, CT, MRI, or specialised bile duct imaging may be recommended.

Other investigations: In selected cases, further blood tests or procedures may be needed to determine the underlying diagnosis.

Not every patient requires every test. Investigations are chosen based on symptoms and clinical findings.

How Is Jaundice Treated?

There is no single treatment for jaundice because management depends on its cause.

• Viral hepatitis: Treatment depends on the specific virus and the severity of the infection.

• Bile duct obstruction: Endoscopic or surgical treatment may be needed to restore bile flow.

• Medicine-related liver injury: Medical supervision is required to identify and manage the responsible substance.

• Haemolysis: Treatment focuses on the underlying blood disorder or cause of red blood cell breakdown.

• Advanced liver disease: Management may involve specialised medical care and monitoring for complications.

Avoid self-medication, unverified herbal remedies, and restrictive diets promoted as quick cures for jaundice. Maintain adequate hydration and nutrition as tolerated, and follow individual medical advice.

Conclusion

Jaundice in adults is an important warning sign that should not be overlooked. It may result from viral hepatitis, liver inflammation, gallstones, medication-related injury, increased red blood cell breakdown, or other liver and bile duct conditions.

Identifying the underlying cause is essential for choosing appropriate treatment and preventing complications. If you notice yellowing of your eyes or skin, dark urine, or pale stools, seek prompt medical evaluation instead of relying on home remedies.
