The normal range of total bilirubin is 3.4~17.1μmol/L. Total bilirubin of 26μmol/L belongs to mild elevation, which can be seen in the physiological elevation caused by strenuous exercise and is generally not serious, or it can be the pathological elevation caused by hepatitis, obstructive jaundice, cirrhosis and so on, which is relatively more serious. 1. Physiological increase: Physiological jaundice in newborn babies (without other discomfort, subsiding in a week or so), prolonged consumption of alcohol, strenuous exercise, etc. may cause an increase in total bilirubin. Physiological causes of total bilirubin increase, generally can be self-recovery, not serious. 2. Pathological increase: including hepatitis, obstructive jaundice, cirrhosis, neonatal pathological jaundice, cholelithiasis, pancreatic head cancer, hemolytic jaundice, etc. In addition, taking special medicines can also lead to total bilirubin increase, such as salicylic acid, erythromycin, rifampicin, progesterone, anandamide and so on. You should consult a doctor for a clear diagnosis and follow the doctor’s instructions for treatment. If the total bilirubin is elevated, please go to the hospital in time, do not take medication on your own, so as not to cause unnecessary damage.
