Liver fibrillation refers to the phenomenon of liver tremor, which is an abnormal manifestation. The liver itself does not show tremor, so liver fibrillation may be caused by bile duct spasm, cirrhosis and other diseases. 1. Bile duct spasm: patients with bile duct spasm may experience liver tremor, and patients with bile duct spasm may also experience paroxysmal abdominal pain or back radiating pain. Some patients with bile duct spasm may also have jaundice or other symptoms, including dyspepsia, constipation, belching, vomiting and other non-specific symptoms. 2. Cirrhosis: Cirrhosis is also one of the causes of liver tremor. In addition to liver tremor, patients with cirrhosis may also experience loss of appetite, abdominal pain, and fatigue. Patients who feel liver tremor should go to the hospital for examination in time, and carry out targeted treatment after clarifying the cause.
