High bilirubin and normal aminotransferases are considered to be the result of obstruction of the biliary system, most commonly bile duct stones, including intrahepatic and extrahepatic bile duct stones, and recurrent right upper abdominal pain, triggered by eating fatty foods or overeating. Shoulder and back discomfort, accompanied by nausea and vomiting, may also occur during attacks. If there is a combination of obstruction and infection of the biliary system, jaundice may be evident and surgery may be required if necessary. The cause of stone formation in the bile duct is considered to be related to bile stasis. In addition, abnormal metabolism of bile salts can also lead to local nodule formation and even affect the bile evacuation. Usually, you should also pay attention to the structure of your diet, abstain from smoking, alcohol, barbecue and other high-fat diets, and not overeat.
