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, and certain medications. Symptoms may include jaundice, confusion, and abdominal swelling, indicating that the liver is unable to perform its essential functions. This condition requires immediate medical attention, as it can lead to serious complications, including bleeding and infection. Treatment often involves hospitalization, where doctors may provide supportive care and, in severe cases, consider a liver transplant. Early diagnosis is crucial for improving outcomes in patients with acute liver failure.
