Yellowing of Eyes: Causes, Symptoms, and Treatment

What is Yellowing of Eyes?

Yellowing of the eyes, medically known as scleral icterus, occurs when the whites of the eyes (sclera) take on a yellowish tint. This discoloration is often a sign of an underlying medical condition, most commonly related to the liver, gallbladder, or blood disorders. The yellow color comes from bilirubin, a yellow pigment produced during the breakdown of red blood cells. Normally, the liver processes bilirubin and excretes it through bile. When this process is disrupted, bilirubin builds up in the blood, leading to jaundice—a condition characterized by yellowing of the skin and eyes.

While yellowing of the eyes can sometimes be harmless, it may also indicate a serious health issue that requires medical attention. According to the Mayo Clinic, jaundice is a symptom, not a disease itself, and understanding its causes is crucial for proper treatment.

Common Causes

Yellowing of the eyes can result from various conditions. Below are some of the most common causes:

• Hepatitis: Inflammation of the liver, often caused by viral infections (Hepatitis A, B, or C), alcohol abuse, or toxins. The CDC notes that hepatitis can impair the liver's ability to process bilirubin.
• Liver Cirrhosis: Long-term damage to the liver, often due to chronic alcoholism or hepatitis, leads to scarring and reduced liver function.
• Gallstones: Hardened deposits in the gallbladder can block the bile duct, preventing bilirubin from being excreted properly.
• Pancreatic Cancer: Tumors in the pancreas can obstruct the bile duct, leading to a buildup of bilirubin.
• Hemolytic Anemia: A condition where red blood cells are destroyed faster than they can be produced, leading to excess bilirubin. This can be caused by autoimmune disorders or genetic conditions like sickle cell anemia.
• Gilbert's Syndrome: A mild, inherited liver disorder that impairs the processing of bilirubin, often without causing serious harm.
• Alcohol-Related Liver Disease: Excessive alcohol consumption can damage the liver, leading to inflammation and impaired function.
• Medication Side Effects: Certain drugs, such as acetaminophen (in high doses), some antibiotics, or chemotherapy drugs, can affect liver function.
• Newborn Jaundice: Common in infants, this occurs because a baby's liver is not fully developed and may struggle to process bilirubin. It usually resolves on its own but may require treatment if severe.
• Biliary Atresia: A rare condition in infants where the bile ducts are blocked or absent, leading to liver damage if untreated.

Other less common causes include infections like malaria, certain metabolic disorders, and rare genetic conditions.

Associated Symptoms

Yellowing of the eyes is often accompanied by other symptoms, which can help identify the underlying cause. These may include:

• Yellowing of the skin (jaundice)
• Dark urine: Bilirubin in the urine can make it appear darker than usual.
• Pale or clay-colored stools: A lack of bilirubin in the stool can cause it to lose its normal brown color.
• Fatigue and weakness: Common in liver diseases or anemia.
• Abdominal pain or swelling: Often seen in conditions like gallstones or liver cirrhosis.
• Nausea and vomiting: Can occur with hepatitis or gallbladder issues.
• Fever or chills: May indicate an infection, such as hepatitis or malaria.
• Itchy skin (pruritus): Common in conditions where bile flow is obstructed.
• Weight loss: Unexplained weight loss may accompany serious conditions like pancreatic cancer.
• Confusion or mental changes: In severe liver disease, toxins can build up in the brain, leading to hepatic encephalopathy.

If you notice yellowing of the eyes along with any of these symptoms, it’s important to consult a healthcare provider for further evaluation.

When to See a Doctor

Yellowing of the eyes should never be ignored, especially if it persists or is accompanied by other symptoms. You should seek medical attention if:

• The yellowing is sudden or severe.
• You experience abdominal pain, particularly in the upper right side.
• You have dark urine or pale stools.
• You feel unusually tired, weak, or confused.
• You have a fever, nausea, or vomiting.
• You notice unexplained weight loss.
• The yellowing is accompanied by itching.
• You have a history of liver disease, alcohol abuse, or exposure to hepatitis.

According to the National Institutes of Health (NIH), early diagnosis and treatment of conditions causing jaundice can prevent complications and improve outcomes.

Diagnosis

If you visit a doctor for yellowing of the eyes, they will likely perform a thorough evaluation to determine the underlying cause. This may include:

• Medical History: Your doctor will ask about your symptoms, medical history, alcohol use, medications, and any recent illnesses or exposures.
• Physical Examination: The doctor will check for signs of liver disease, such as abdominal tenderness, swelling, or enlarged liver.
• Blood Tests:
  • Liver function tests (LFTs): Measure enzymes and proteins in the blood to assess liver health.
  • Bilirubin levels: High levels indicate jaundice.
  • Complete blood count (CBC): Checks for anemia or infection.
  • Viral hepatitis tests: Detects hepatitis A, B, or C.
• Imaging Tests:
  • Ultrasound: Checks for gallstones, liver abnormalities, or blockages in the bile ducts.
  • CT Scan or MRI: Provides detailed images of the liver, pancreas, and bile ducts.
  • Endoscopic Retrograde Cholangiopancreatography (ERCP): A procedure to examine the bile ducts and pancreas.
• Liver Biopsy: In some cases, a small sample of liver tissue may be taken to check for cirrhosis, cancer, or other liver diseases.

The Cleveland Clinic emphasizes that diagnosing the cause of jaundice often requires a combination of these tests to pinpoint the exact issue.

Treatment Options

The treatment for yellowing of the eyes depends on the underlying cause. Here are some common approaches:

Medical Treatments

• Hepatitis Treatment:
  • Antiviral medications for viral hepatitis (e.g., interferon for Hepatitis B or C).
  • Supportive care, such as rest, hydration, and avoiding alcohol.
• Gallstones:
  • Medications to dissolve gallstones (ursodeoxycholic acid).
  • Surgery to remove the gallbladder (cholecystectomy) if stones are causing blockages.
• Liver Cirrhosis:
  • Lifestyle changes, such as abstaining from alcohol and eating a healthy diet.
  • Medications to manage complications like fluid retention or hepatic encephalopathy.
  • Liver transplant in severe cases.
• Pancreatic Cancer:
  • Surgery to remove the tumor if possible.
  • Chemotherapy or radiation to shrink or slow the growth of the cancer.
• Hemolytic Anemia:
  • Blood transfusions in severe cases.
  • Medications to suppress the immune system if the anemia is autoimmune-related.
• Newborn Jaundice:
  • Phototherapy: Exposure to special lights helps break down bilirubin.
  • Exchange transfusion in severe cases to replace the baby’s blood.

Home and Lifestyle Remedies

While medical treatment is essential for underlying conditions, certain lifestyle changes can support liver health and reduce symptoms:

• Avoid alcohol: Alcohol can worsen liver damage.
• Stay hydrated: Drinking plenty of water helps the liver function properly.
• Eat a balanced diet: Focus on fruits, vegetables, lean proteins, and whole grains. Avoid fatty or fried foods.
• Limit medications: Only take necessary medications and avoid overdosing on acetaminophen (Tylenol).
• Exercise regularly: Helps maintain a healthy weight and reduces fat buildup in the liver.
• Avoid exposure to toxins: Be cautious with chemicals, pesticides, and other liver-damaging substances.

Always consult your doctor before making significant changes to your diet or lifestyle, especially if you have an underlying medical condition.

Prevention Tips

While not all causes of yellowing of the eyes can be prevented, you can take steps to reduce your risk:

• Get vaccinated: Vaccines are available for Hepatitis A and B. The World Health Organization (WHO) recommends vaccination as a key prevention strategy.
• Practice safe sex: Hepatitis B and C can be transmitted sexually. Use protection and get tested regularly if you’re at risk.
• Avoid sharing needles: This reduces the risk of Hepatitis B and C transmission.
• Limit alcohol consumption: Excessive alcohol is a leading cause of liver disease.
• Maintain a healthy weight: Obesity can lead to fatty liver disease, which may progress to cirrhosis.
• Be cautious with medications: Follow dosage instructions and avoid mixing medications without consulting your doctor.
• Protect against toxins: Wear protective gear when handling chemicals and avoid exposure to environmental toxins.
• Eat a liver-friendly diet: Foods rich in antioxidants (e.g., berries, nuts) and fiber can support liver health.

For newborns, breastfeeding and regular pediatric check-ups can help monitor and manage jaundice early.

Emergency Warning Signs

Yellowing of the eyes can sometimes indicate a medical emergency. Seek immediate medical attention if you experience any of the following:

• Severe abdominal pain, especially if it’s sudden and intense.
• High fever with chills, which may indicate a serious infection.
• Confusion, drowsiness, or difficulty waking up, which could signal liver failure or hepatic encephalopathy.
• Vomiting blood or black, tarry stools, indicating internal bleeding.
• Rapid heart rate or difficulty breathing.
• Signs of shock, such as cold, clammy skin, low blood pressure, or fainting.
• Yellowing that spreads rapidly or is accompanied by severe itching.

These symptoms may indicate life-threatening conditions such as acute liver failure, severe infection, or internal bleeding. Do not delay seeking help.

Yellowing of the eyes is a symptom that should always be taken seriously. While it may sometimes result from a mild or temporary condition, it can also signal a severe underlying issue. Early diagnosis and treatment are key to managing the cause and preventing complications. If you or someone you know experiences yellowing of the eyes, consult a healthcare provider promptly for a thorough evaluation.
