The liver mainly has a variety of roles such as secreting bile, synthesizing and transforming many nutrients in the body and detoxifying. If the liver is not good, regardless of gender, there may be signs such as decreased digestive function, abdominal pain, jaundice and spider nevus, but there are not exactly six signs of the situation. 1. Decreased digestive function: Patients with poor liver function will experience symptoms such as abdominal distension, decreased appetite and wasting, which are mainly related to decreased metabolic function of the liver and abnormal bile secretion function. In addition, cirrhotic patients due to elevated portal pressure leads to esophageal varices in the fundus of the stomach, causing cirrhotic gastropathy, affecting the patient’s digestive function, and in serious cases may also cause gastrointestinal bleeding; 2, abdominal pain: the liver is located in the upper right abdomen of the body, when the patient’s liver damage may appear right upper abdominal distension and pain, and in severe cases may also cause back and scapular radiating pain; 3, jaundice: liver cell damage will lead to blood within bilirubin will rise, and patients will have symptoms such as yellowing and itching all over the body; 4. Spider nevus: the liver is an important metabolic organ of the human body, and if liver function decreases, estrogen inactivation will decrease, leading to the formation of small arteries that are dilated and resemble spiders, hence the name spider nevus; 5. Lower limb edema and ascites: decreased liver function and insufficient synthesis of albumin will cause patients to have symptoms such as ascites and lower limb edema; 6: In addition to the above common symptoms, patients may also experience atypical symptoms such as weakness, poor sleep, dull yellow face, irritability, and decreased immunity. Patients can improve liver function tests, as well as imaging examinations such as CT of the upper abdomen and liver ultrasound to clarify the diagnosis.
