Acute liver failure is a rapid decline in liver function that occurs within days or weeks. It can be caused by various factors, including viral infections, excessive alcohol consumption, or certain medications like acetaminophen. Symptoms may include jaundice, confusion, and bleeding. This condition is a medical emergency that requires immediate attention. Treatment often involves hospitalization, where doctors may provide supportive care, manage complications, and in severe cases, consider a liver transplant. Early diagnosis and intervention are crucial for improving outcomes in patients with acute liver failure.
