Generally, physiological jaundice appears three days after birth and can subside on its own in about half a month. Two-month-old babies who still have jaundice may be caused by pathological jaundice, and it is recommended to visit the hospital promptly to determine the cause and treat the cause. Common causes and treatment 1, breast milk jaundice: high levels of β-glucuronidase in breast milk can catalyze the transformation of conjugated bilirubin into unconjugated bilirubin, this process is carried out in the small intestine, coupled with the relatively slow intestinal peristalsis of the baby, so that a large amount of excreted bilirubin is dissociated by this enzyme into unconjugated bilirubin, increased absorption, that is, the emergence of breast milk jaundice. At this time, a small number of meals can be fed, abdominal massage in a clockwise direction to increase intestinal peristalsis, taking anti-yellowing drugs such as gardenia yellow granules to promote the excretion of bilirubin, but also the use of blue light irradiation, with more sunshine to improve the symptoms. Breast milk jaundice need not worry too much, the prognosis is generally good, so it is recommended to adhere to breastfeeding; 2, cytomegalovirus infection: infection with this virus causes jaundice, the application of more ciclovir, valacyclovir anti-infective treatment, but also the use of reduced glutathione to protect the liver; 3, other: abnormal thyroid function or other genetic metabolic diseases can lead to jaundice in two-month-old babies. Parents are advised to take their babies to the doctor in time to identify the cause and treat the cause, and should not dispose of it on their own to avoid delay.
