Alcoholic hepatitis is inflammation of the liver caused by long-term, excessive consumption of alcohol. The condition can range in severity from mild to life-threatening and is typically diagnosed with blood tests, imaging studies, and liver biopsy. Symptoms of alcoholic hepatitis may include fatigue, loss of appetite, weight loss, abdominal pain, jaundice, and fever. Treatment may involve abstinence from alcohol, medication to reduce inflammation and support liver function, and lifestyle changes such as a healthy diet and regular exercise. In severe cases, hospitalization and liver transplant may be necessary.
