What are the Causes of Vitamin K Deficiency in Neonates?
There are several causes of vitamin K deficiency in newborns:
1. Low Vitamin K Stores at Birth: Newborns naturally have low stores of vitamin K because it does not cross the placenta efficiently. 2. Lack of Gut Bacteria: Vitamin K is synthesized by gut bacteria, but newborns have a sterile gut at birth, lacking these bacteria. 3. Breastfeeding: Breast milk contains lower levels of vitamin K compared to formula milk. 4. Maternal Medication: Certain medications taken by the mother during pregnancy, such as anticonvulsants or antibiotics, can affect the vitamin K levels in the newborn.
