The causes of neonatal jaundice are different, and their dietary contraindications are also different. 1, fava bean disease: heel blood test has a clear G6PD enzyme deficiency, newborns should avoid the use of drugs that can cause hemolysis, such as antipyretic analgesics, antimalarials, sulfonamides, heartburn, etc., anti-mold become naphthalene (camphor) may lead to the occurrence of hemolytic jaundice, breastfeeding, the baby all contraindicated drugs and food such as fava beans, the mother is also not allowed to use, otherwise it is also easy to cause the occurrence of hemolytic jaundice. 2, breast milk jaundice, jaundice symptoms last longer, but the baby grows well, diet and height and weight development is normal, while liver function measurement and no obvious functional damage, consider breast milk jaundice. The diagnosis of breast milk jaundice is usually made when breast milk is stopped for 3-5 days and the bilirubin drops significantly by more than 50%. Bilirubin rises after reintroduction of breast milk, but usually does not rise again to the previous value. Babies can continue breastfeeding and have their liver function monitored regularly. Early breast milk jaundice may be due to inadequate feeding, resulting in poor gastrointestinal motility in the baby and failure to excrete metabolites thus causing the jaundice to persist, so be sure to give your baby enough feedings. Late onset breast milk jaundice is due to certain components of breast milk that inhibit bilirubin metabolism. Make it clear which type of jaundice your baby has so that you can avoid it in a more targeted way during the usual diet.
