Patients with poor liver function usually show darkening of the skin, swelling of the body, yellowing of the eyes, etc. Some patients may also suffer from indigestion and other conditions. 1. Darkening of the skin: when the skin becomes yellowish and dull, it is due to the abnormalities of liver function that lead to hormone metabolism disorders, which further cause abnormalities in the metabolism of pigments and so on. 2. Swelling: when the plasma osmotic pressure imbalance occurs, the protein in the body is reduced, resulting in vascular fluid infiltration to the tissues triggered by swelling, usually the face and lower limbs are the most obvious swelling. 3. Yellowing of the eyeballs: When the metabolism of bilirubin in the body is affected, the liver is unable to break down the bilirubin, thus leading to jaundice in the whites of the eyes. 4. Indigestion: The liver needs to secrete bile during the digestion of food. If the liver has problems, the lack of bile secretion will lead to decreased digestive ability, nausea, vomiting and other phenomena. If the liver condition is serious, patients need to go to the hospital immediately for examination and treatment, standardized dietary habits and good sleep, daily good liver care measures, quit smoking, quit smoking, eliminate overeating can prevent the occurrence of the disease.
