Hepatic ascites may be associated with increased portal vein pressure, portal vein thrombosis, cirrhosis, hypoproteinemia, increased aldosterone, etc. When liver function is severely impaired, it is unable to break down ammonia in the intestines, and ammonia entering the blood circulation directly causes elevated blood ammonia, which leads to hepatic coma. Hepatic ascites indicates that the function of the liver has been seriously impaired. After the liver function is seriously impaired, the body produces more ammonia, while the ability to metabolize ammonia decreases, and the blood ammonia gradually rises, and the high concentration of blood ammonia can pass through the blood-brain barrier, which affects the energy metabolism of the brain, and thus causes cerebral dysfunction and coma. Patients need to go to the local hospital as soon as possible, strictly follow the doctor’s instructions for medication, and monitor the development of the disease at any time.
