Primary biliary cirrhosis with nausea is commonly associated with dietary habits, decreased liver function, poor secretion of digestive juices and so on. 1. Eating habit: eating too much food, eating some too greasy, too sweet and other indigestible food will easily cause nausea and vomiting. 2. Hepatic hypoplasia: When patients suffer from hepatic hypoplasia, they will have a series of digestive symptoms, such as loss of appetite, anorexia, abdominal distension, nausea and vomiting. 3. Poor secretion of digestive juices: In the advanced stage of primary biliary cirrhosis, there are few surviving liver cells left, which are unable to normally secrete enough bile, which plays an important role in digestion. If the patient has severe vomiting and other symptoms, it is recommended to go to the gastroenterology department of the hospital as soon as possible for standardized treatment under the guidance of physicians.
