Liver failure occurs when the liver loses its ability to function properly, which can happen suddenly (acute liver failure) or gradually over time (chronic liver failure). The liver is essential for filtering toxins from the blood, producing bile for digestion, and regulating various metabolic processes. Causes of liver failure include excessive alcohol consumption, viral infections like hepatitis, and certain medications. Symptoms of liver failure may include jaundice (yellowing of the skin and eyes), swelling in the abdomen, confusion, and fatigue. Treatment options depend on the cause and severity, ranging from medication to liver transplantation in severe cases. Early diagnosis and management are crucial for improving outcomes.
