Signs of liver dysfunction include gastrointestinal symptoms, bleeding tendency, endocrine disorders, ascites, systemic symptoms and so on. 1. Digestive symptoms: the nutrients digested and absorbed by the gastrointestinal tract enter the liver for metabolic reactions through the portal vein blood flow, and a series of digestive symptoms, such as loss of appetite, dyspepsia, nausea and vomiting, abdominal pain and bloating, etc., can appear when the liver is not functioning well. 2. Bleeding tendency: liver is the main organ for synthesizing coagulation factors, when liver insufficiency reduces the synthesis of coagulation factors, patients will have bleeding tendency, for example, bleeding from the mouth and gums, spider nevus, nosebleed, menstrual bleeding, skin purpura and bruises. 3. Endocrine disorders: liver is the organ for inactivation of many hormones, when liver insufficiency reduces the inactivation of related hormones, endocrine disorders will occur, such as gynecomastia, menstrual disorders in females, grayish color, spider nevus and so on. 4. Ascites: when liver insufficiency decreases albumin synthesis, and when combined with portal hypertension, gastrointestinal venous stasis, all of these will increase the generation of intra-abdominal fluid and appear ascites, which will be manifested as abdominal distension and respiratory difficulties. 5. Systemic symptoms: including fever, fatigue, weight loss, edema, etc. It is recommended that patients with poor liver function should go to the hospital as soon as possible and be treated accordingly to avoid further deterioration of liver function or complications.
