Common symptoms of impaired liver function include digestive symptoms, jaundice, discomfort in the liver area, and immune deficiency. 1. Digestive symptoms: The liver is the largest digestive gland in the human body, and its main function is to secrete bile, digest food and regulate metabolism. When liver function is impaired, digestive symptoms such as poor appetite, fatigue, anorexia, nausea, vomiting and loss of appetite are common. 2. Liver discomfort: when liver function is damaged, it may cause pain in the liver area. 3. Jaundice: When liver function is severely damaged, bile secretion decreases, leading to abnormal bilirubin metabolism. At this time, the patient will have jaundice symptoms. Symptoms such as yellowing of skin, yellowing of sclera and yellowing of urine may occur. 4. Low immunity: when liver function is not good, immunoglobulin may be affected, so that the immunity is in a low state, such as frequent illness. If patients have the above symptoms, they should go to regular hospitals in time to improve the relevant examination and get proper treatment under the doctor’s advice.
