In breastmilk jaundice, bili continues to increase after 1st week of life and peaks around _ to _ weeks
The correct answer and explanation is:
Correct Answer: Breastmilk jaundice typically continues to increase after the first week of life and peaks around 2 to 3 weeks of age.
Explanation (300 words):
Breastmilk jaundice is a type of non-pathological neonatal jaundice that is associated with breastfeeding and usually appears after the first week of life. It differs from physiologic jaundice, which occurs within the first few days after birth and resolves by the end of the first week.
In breastmilk jaundice, the bilirubin levels continue to rise beyond the first week and typically peak between 2 to 3 weeks of age. In some cases, elevated bilirubin may persist for up to 12 weeks, though this is less common and usually not harmful if the infant is thriving and other causes of jaundice have been ruled out.
The exact cause of breastmilk jaundice is not fully understood, but it is believed that certain substances in some mothers’ breast milk inhibit the normal conjugation or excretion of bilirubin in the infant’s liver. These substances may include enzymes such as β-glucuronidase, which can deconjugate bilirubin, making it more easily reabsorbed from the intestines back into the bloodstream—a process known as enterohepatic circulation.
It is crucial to distinguish breastmilk jaundice from breastfeeding failure jaundice, which occurs in the first week due to inadequate intake of milk leading to dehydration and poor elimination of bilirubin. Breastmilk jaundice, on the other hand, occurs in well-fed, thriving infants and is usually benign.
Management typically involves continued breastfeeding, as interruption is rarely necessary. However, close monitoring of bilirubin levels is important to rule out more serious causes of prolonged jaundice.
In summary, in breastmilk jaundice, bilirubin levels rise after the first week of life and peak between 2 and 3 weeks, reflecting a benign and self-limiting condition in healthy, breastfed infants.
