Jaundice in Adults: Understanding the Causes and When to See a Doctor
Jaundice is a condition that causes the skin and whites of the eyes to turn yellow. Although it is often associated with liver problems, jaundice can also develop due to gallstones, bile duct obstruction, certain medications, and disorders that cause the breakdown of red blood cells.
In adults, jaundice should never be ignored. It may be the first visible sign of an underlying health condition that requires medical evaluation. Recognising its symptoms, understanding the possible causes, and seeking timely care can help doctors identify the problem and plan appropriate treatment.
In this article, we explain what jaundice is, why it occurs in adults, how it is diagnosed, and when you should consult a doctor.
What Is Jaundice and Why Does It Occur?
Jaundice occurs when a yellow pigment called bilirubin builds up in the blood. Bilirubin forms naturally when the body breaks down old or damaged red blood cells.
Under normal circumstances, the liver processes bilirubin and helps eliminate it through bile, which travels into the digestive tract. When bilirubin production increases, the liver cannot process it effectively, or the flow of bile becomes blocked, bilirubin levels may rise.
This accumulation causes the characteristic yellow discolouration of the eyes and skin.
Jaundice is not a disease by itself. It is a symptom of an underlying condition, and identifying the cause is essential for determining the appropriate treatment.
Common Causes of Jaundice in Adults
Several medical conditions can interfere with the normal processing or removal of bilirubin. The most common causes include the following.
1. Viral Hepatitis
Hepatitis refers to inflammation of the liver. Viral infections, including hepatitis A, B, and E, as well as hepatitis C, can affect liver function and sometimes cause jaundice.
The way these infections spread differs. Hepatitis A and E are commonly associated with contaminated food or water, while hepatitis B and C can spread through infected blood, with hepatitis B also transmitted through certain bodily fluids.
Symptoms may include yellowing of the eyes, dark urine, fatigue, nausea, reduced appetite, and abdominal discomfort.
What you should know: The appropriate treatment depends on the type of hepatitis and its severity. Medical assessment and specific tests can help establish the diagnosis.
2. Fatty Liver and Other Liver Diseases
Fatty liver disease occurs when excess fat accumulates in the liver. It is often associated with obesity, diabetes, and metabolic conditions.
Fatty liver in its early stages does not usually cause jaundice. However, advanced liver disease, significant inflammation, or cirrhosis may interfere with normal liver function and lead to jaundice.
Alcohol-related liver disease and certain autoimmune or inherited liver disorders can also affect bilirubin processing.
People with known liver disease should seek prompt medical assessment if yellowing of the eyes or skin develops.
3. Gallstones and Bile Duct Obstruction
The liver produces bile, which helps digest fats and carries bilirubin into the digestive tract. Gallstones can sometimes move into the common bile duct and block the normal flow of bile.
When bile cannot drain properly, bilirubin may accumulate in the bloodstream, resulting in jaundice.
Other symptoms may include:
Pain in the upper right side of the abdomen.
Dark-coloured urine.
Pale or clay-coloured stools.
Itching of the skin.
Nausea or vomiting.
A blocked bile duct can sometimes lead to an infection. Jaundice accompanied by fever, chills, or significant abdominal pain requires urgent medical attention.
4. Alcohol-Related Liver Damage
Long-term heavy alcohol consumption can damage liver cells and cause inflammation. In some cases, this may progress to severe liver disease and jaundice.
Associated symptoms can include fatigue, loss of appetite, nausea, abdominal swelling, and yellowing of the eyes.
If alcohol-related liver disease is suspected, a doctor may recommend blood tests, imaging, and further evaluation. Avoid alcohol and seek professional advice. People with alcohol dependence should obtain medical guidance before stopping abruptly because withdrawal can be dangerous.
5. Medication-Related Liver Injury
Certain prescription medicines, over-the-counter medications, and herbal supplements can cause liver injury in some individuals. The risk depends on the product, dosage, other medications, and the person's health.
For example, excessive doses of paracetamol can cause serious liver damage.
If jaundice develops after starting a new medicine or supplement, seek prompt medical advice. Provide your doctor with a list of everything you take, and do not discontinue essential prescription medicines without appropriate guidance.
6. Increased Breakdown of Red Blood Cells
Sometimes, jaundice develops because red blood cells break down faster than usual. This process, known as haemolysis, produces bilirubin faster than the body can process it.
Certain blood disorders, immune-related conditions, infections, and medication reactions can contribute to this problem.
Blood tests can help determine whether increased red blood cell breakdown is responsible for the symptoms.
Symptoms of Jaundice You Should Recognise
Yellowing of the whites of the eyes is often one of the first noticeable signs of jaundice. The skin may also appear yellow, although this can be harder to recognise on darker skin tones.
Depending on the underlying cause, other symptoms may include:
Dark or tea-coloured urine.
Pale or clay-coloured stools.
Persistent itching.
Fatigue and weakness.
Loss of appetite.
Nausea or vomiting.
Abdominal pain or discomfort.
Unexplained weight loss in some cases.
Not everyone experiences all these symptoms. Their presence and severity depend on the underlying condition.
Important: If you notice new yellowing of the eyes or skin, arrange prompt medical evaluation rather than waiting for the symptoms to resolve on their own.
Jaundice in adults can sometimes indicate a serious medical condition. Even if there is no pain, new jaundice requires prompt assessment.
Seek urgent medical care if jaundice is accompanied by:
Severe or sudden abdominal pain.
Fever or chills.
Repeated vomiting.
Confusion or unusual drowsiness.
Unusual bleeding or easy bruising.
Rapidly worsening symptoms.
These warning signs may indicate a serious liver problem, bile duct infection, or another condition requiring immediate attention.
Persistent jaundice with unexplained weight loss or pale stools should also be investigated promptly. These symptoms do not necessarily indicate cancer, but they can occur with conditions that need timely diagnosis.
How Is Jaundice Diagnosed?
Diagnosis begins with a medical history and physical examination. The doctor may ask about symptom duration, medications, alcohol consumption, recent illnesses, and other relevant medical factors.
Depending on the findings, investigations may include:
Blood tests: Bilirubin measurements and liver enzyme tests help assess bilirubin levels and identify patterns of liver injury. Additional tests may check for viral hepatitis, blood disorders, or problems with blood clotting.
Abdominal ultrasound: This may help identify gallstones, bile duct dilation, and certain structural changes in the liver.
CT or MRI scans: Additional imaging may be recommended if the initial evaluation suggests a blockage or another condition requiring closer examination.
Further investigations: In selected cases, specialised bile duct procedures or other tests may be necessary to establish the diagnosis.
Not every patient requires all these investigations. The doctor selects tests according to the symptoms, examination findings, and suspected cause.
How Is Jaundice Treated?
There is no single treatment for jaundice because the appropriate approach depends on its underlying cause.
Viral hepatitis: Management depends on the type of infection and the severity of the illness.
Gallstones or bile duct obstruction: An endoscopic or surgical procedure may be required to restore bile flow.
Medication-related liver injury: The suspected medicine or supplement needs careful medical review and appropriate management.
Blood disorders: Treatment focuses on the condition responsible for increased red blood cell breakdown.
Advanced liver disease: Specialist care may be needed to manage complications and monitor liver function.
Avoid relying on unverified home remedies, herbal preparations, or restrictive diets marketed as quick cures for jaundice. Follow medical advice regarding nutrition, hydration, medications, and follow-up appointments.
Conclusion
Jaundice in adults is an important symptom that may be linked to liver inflammation, viral hepatitis, gallstones, bile duct obstruction, medication-related injury, or blood disorders. Although the causes vary, identifying the underlying problem is the first step towards appropriate treatment.
Do not ignore yellowing of the eyes or skin, especially when accompanied by dark urine, pale stools, abdominal pain, or unexplained weight loss. Timely medical assessment can help identify the cause and determine the next steps in care.
For concerns about jaundice or liver health, consult a qualified doctor for an appropriate evaluation and personalised medical guidance.
