Liver problems may manifest in the body as digestive symptoms, malnutrition and jaundice. 1. Digestive system symptoms: Generally, gastrointestinal venous blood flow enters the liver through the portal vein. When there are problems with the liver, there may be stagnation of blood in the gastrointestinal tract and obstruction of digestion and absorption, which may lead to nausea, anorexia, abdominal distension, diarrhea and other symptoms. 2. Malnutrition: usually the liver is the largest metabolic organ in the human body, when the liver has problems, many metabolic reactions of the body will be abnormal, which will lead to malnutrition symptoms such as weight loss, fatigue, and mental weakness. 3. Jaundice: human bilirubin is metabolized in liver cells, when the liver has problems, the body’s bilirubin metabolism will be affected, resulting in increased levels of bilirubin in the blood, which will make the patient develop yellow skin and sclera. Other symptoms may also occur when liver problems occur. It is recommended that patients should consult a doctor when they experience the above mentioned discomforts, and make a clear diagnosis under the guidance of a professional doctor to avoid delaying the condition.
