What Causes Liver Blockage?


The term “liver blockage” is not specific, and it’s essential to understand the context or specific condition being referred to. The liver itself doesn’t usually experience blockages, but there are several conditions that can affect the liver and its associated ducts. Here are some conditions that may involve obstruction or blockage in the liver or its drainage system:

  1. Gallstones: Gallstones are solid particles that can form in the gallbladder and occasionally block the common bile duct, which is the tube that carries bile from the gallbladder to the small intestine. This blockage can affect the flow of bile, impacting liver function.
  2. Biliary strictures: Narrowing or blockage of the bile ducts due to scarring, inflammation, or tumors can lead to obstruction of bile flow and affect the liver.
  3. Liver cysts: Cysts can develop in the liver, potentially causing compression of nearby structures and affecting normal liver function.
  4. Primary sclerosing cholangitis (PSC): PSC is a chronic disease that causes inflammation and scarring of the bile ducts inside and outside the liver, leading to strictures and blockages.
  5. Bile duct stones: Similar to gallstones, stones can form in the bile ducts and cause obstruction.
  6. Liver tumors: Both benign and malignant tumors in the liver or adjacent structures can cause blockages and affect liver function.
  7. Hepatitis: Inflammation of the liver due to viral hepatitis (such as hepatitis B or C) or other causes can lead to scarring and potentially cause blockages over time.
  8. Cirrhosis: Advanced liver disease, often resulting from long-term inflammation and scarring, can lead to changes in liver structure and function, including potential blockages.
  9. Parasitic infections: Certain parasites can affect the liver and bile ducts, leading to obstruction.

If you suspect a problem with your liver or are experiencing symptoms such as abdominal pain, jaundice (yellowing of the skin or eyes), dark urine, or pale stools, it’s important to seek medical attention. A healthcare provider can conduct a thorough evaluation, which may include imaging studies, blood tests, and other diagnostic procedures to identify the underlying cause of the symptoms and determine the appropriate treatment.
