There are many reasons for high bilirubin and dizziness, including inborn abnormalities of bilirubin metabolism and hepatobiliary diseases. 1. Inborn abnormalities of bilirubin metabolism: such as non-hemolytic jaundice, indirect bilirubin increase is more common, mostly occurring in male adolescents, and jaundice will gradually improve with age. 2. Hepatobiliary diseases: such as hepatitis, drug-induced liver damage, biliary obstruction, cirrhosis, hepatocellular carcinoma and so on. Since bilirubin is metabolized through hepatic and intestinal circulation, if the liver cells are damaged, the metabolism of bilirubin will be seriously affected, which will result in elevated bilirubin. If hepatic encephalopathy occurs, the patient will also have dizziness, confusion of behavior and consciousness or even coma. In addition to the above diseases, blood transfusion with incompatible blood groups, biliary parasitic diseases, and physiologic jaundice can cause high bilirubin. Most of these diseases are accompanied by nausea, vomiting and dizziness. It is recommended to go to the hospital to find out the cause of the disease and under the guidance of the doctor to carry out regular treatment.
