The yellowing of the eyes, clinically known as jaundice, can stem from various underlying factors, typically indicating an issue with the liver, gallbladder, or red blood cells. Jaundice manifests when there’s an excess buildup of bilirubin, a yellow pigment produced during the breakdown of old red blood cells. Bilirubin is typically processed by the liver and then excreted through bile, but when this process is disrupted, it accumulates in the body, leading to yellowing of the skin and eyes.
One primary cause of jaundice is liver diseases such as hepatitis, cirrhosis, or liver cancer. These conditions can impair the liver’s ability to process bilirubin effectively, resulting in its accumulation in the bloodstream and subsequent yellowing of the eyes. Hepatitis, in particular, can cause inflammation of the liver, hindering its normal function.
Gallstones, which obstruct the flow of bile from the gallbladder into the small intestine, can also lead to jaundice. When bile flow is impeded, bilirubin can’t be properly eliminated from the body, causing it to accumulate and manifest as jaundice. Additionally, tumors in the bile ducts can obstruct bile flow, contributing to jaundice.
Another potential cause is hemolytic anemia, a condition characterized by the accelerated destruction of red blood cells. When red blood cells break down, they release bilirubin, which, if the liver can’t process efficiently, can lead to jaundice. Hemolytic anemia can be caused by various factors, including autoimmune disorders, certain medications, or inherited conditions such as sickle cell anemia.
Liver infections, such as those caused by viruses like hepatitis A, B, or C, can also result in jaundice. These infections can impair liver function, leading to the accumulation of bilirubin in the bloodstream and subsequent yellowing of the eyes.
In newborns, jaundice is relatively common and often benign. It typically occurs due to the immature liver’s inability to effectively process bilirubin in the early days after birth. This type of jaundice usually resolves on its own without treatment but may require monitoring in severe cases.
Less common causes of jaundice include pancreatic cancer, Gilbert’s syndrome (a genetic disorder affecting bilirubin metabolism), and certain medications that can cause liver damage or interfere with bile flow.
Symptoms of jaundice may vary depending on the underlying cause and severity of the condition but often include yellowing of the skin and whites of the eyes, dark urine, pale stools, fatigue, abdominal pain, nausea, and vomiting. Treatment for jaundice typically involves addressing the underlying cause. For example, liver diseases may require medications, lifestyle changes, or in severe cases, liver transplantation. In cases of bile duct obstruction, surgical intervention may be necessary to remove gallstones or tumors. Overall, prompt medical evaluation is crucial for accurate diagnosis and appropriate management of jaundice.

Jaundice, characterized by the yellowing of the skin and whites of the eyes, is a clinical manifestation of underlying health conditions affecting the liver, gallbladder, or red blood cells. The yellow hue results from an excess accumulation of bilirubin, a yellow pigment produced during the breakdown of hemoglobin in old red blood cells. Typically, bilirubin is processed by the liver, conjugated with glucuronic acid, and then excreted into bile for elimination from the body. However, when this process is disrupted, bilirubin levels can rise, leading to jaundice.
Liver diseases represent a significant cause of jaundice. Hepatitis, which encompasses several viral infections (hepatitis A, B, C, etc.), can lead to liver inflammation and impairment of its function. Chronic hepatitis, particularly hepatitis B and C, can progress to cirrhosis, a condition characterized by extensive scarring of the liver tissue, further compromising its ability to process bilirubin effectively. Liver cancer, whether primary hepatocellular carcinoma or metastatic from other sites, can also disrupt normal liver function, contributing to jaundice.
Gallstones, another common cause of jaundice, obstruct the flow of bile from the gallbladder into the small intestine. This obstruction prevents bilirubin from being excreted properly, leading to its accumulation in the bloodstream and subsequent jaundice. In addition to gallstones, tumors in the bile ducts or pancreatic cancer can also obstruct bile flow, resulting in jaundice.
Hemolytic disorders, such as hemolytic anemia, accelerate the breakdown of red blood cells, releasing excess bilirubin into the bloodstream. When the liver cannot process this bilirubin efficiently, jaundice may occur. Hemolytic anemia can be caused by various factors, including autoimmune diseases, infections, medications, or inherited conditions like sickle cell anemia.
In newborns, jaundice is relatively common due to the immature liver’s inability to process bilirubin efficiently in the first few days after birth. This type of jaundice, known as physiological jaundice, usually resolves without treatment but may require monitoring in severe cases. However, excessive jaundice in newborns may indicate pathological causes such as hemolytic disease of the newborn or breastfeeding-associated jaundice, requiring medical attention.
Less common causes of jaundice include genetic disorders like Gilbert’s syndrome, where there’s a defect in bilirubin metabolism, leading to mild, intermittent jaundice without significant liver dysfunction. Certain medications, such as acetaminophen (paracetamol) in overdose or prolonged use, can cause liver damage (hepatotoxicity) and subsequent jaundice. Other drugs may interfere with bile flow or liver function, contributing to jaundice as a side effect.
Symptoms of jaundice may vary depending on the underlying cause and severity but often include yellowing of the skin and eyes, dark urine, pale stools, fatigue, abdominal pain, nausea, and vomiting. Diagnosis typically involves a thorough medical history, physical examination, blood tests to assess liver function and bilirubin levels, imaging studies (such as ultrasound, CT scan, or MRI) to evaluate the liver and bile ducts, and sometimes liver biopsy for further evaluation.
Treatment for jaundice aims to address the underlying cause. Depending on the specific condition, treatment may involve medications to manage liver diseases or infections, lifestyle modifications such as dietary changes and alcohol avoidance, interventions to remove bile duct obstructions (e.g., surgical removal of gallstones or tumors), or liver transplantation in severe cases of liver failure. Close monitoring and follow-up are essential to monitor bilirubin levels and ensure appropriate management of jaundice and its underlying cause.
