Liver injury refers to damage to the liver, which can result from various factors such as excessive alcohol consumption, viral infections like hepatitis, or exposure to toxic substances. The liver plays a crucial role in detoxifying the body, producing proteins, and aiding digestion. When injured, its ability to function properly can be compromised, leading to serious health issues. Symptoms of liver injury may include fatigue, jaundice (yellowing of the skin and eyes), abdominal pain, and swelling. Diagnosis typically involves blood tests to assess liver function and imaging studies. Early detection and treatment are essential to prevent further damage and complications, such as liver failure or cirrhosis.
