High bile acids are generally considered to be related to psychological factors, hepatocellular damage, obstructive jaundice, etc. It is not usually necessary to be treated by infusion and sometimes surgery. 1. Psychological factors: normal people will have a transient elevation of serum bile acids after eating, which is a normal phenomenon, the elevated index is not too high, and usually can be lowered without treatment. 2. Hepatocellular damage: mainly because the liver is damaged by viruses, drugs and other reasons, such as acute viral hepatitis, chronic active hepatitis, as well as cirrhosis, hepatocellular carcinoma and other damage to liver cells, resulting in a significant increase in bile acids. Generally, it can be lowered by treating the cause and liver-protecting treatment. 3. Obstructive jaundice: the common causes are bile duct obstruction, such as stones in the common bile duct, tumors in the bile duct, tumors in the jugular abdominal area, which leads to poor bile excretion, causing bile acid to flow back into the blood, causing bile acid to rise. Infusions are not effective in lowering bile acids, and surgery is needed to relieve the obstruction to effectively lower bile acids. When bile acid is elevated, you should seek medical treatment as soon as possible to improve the relevant examinations, to clarify the specific causes, and treat under the guidance of the doctor.
