Triple bilirubin refers to three items of bilirubin, i.e. total bilirubin, direct bilirubin and indirect bilirubin. A high triple bilirubin, but all other liver function indexes are normal, may be caused by physiological reasons such as heavy exercise and physiological jaundice, but it may also be caused by pathologic reasons such as hepatitis, cirrhosis, and drug damage. 1. Physiological reasons: some patients may have elevated bilirubin after strenuous exercise, long-term alcohol consumption or physiological jaundice in newborns, which is mostly due to physiological reasons, and can be restored to normal after removing triggering factors. 2. Pathological factors: when suffering from hepatitis, cirrhosis, pancreatic head cancer, neonatal pathologic jaundice and other diseases, it may also lead to the phenomenon of high bilirubin, while other indicators are normal. When some patients take salicylic acid, erythromycin, rifampicin and other drugs, it may also damage the liver cells, resulting in three elevated bilirubin. There are many reasons for elevated bilirubin, so it is recommended that you follow the doctor’s instructions for treatment after the doctor’s consultation and other related tests to determine the cause of the disease.
