Hemorrhagic disease of the newborn is a bleeding disorder that usually develops shortly after a baby is born.
A lack of vitamin K causes hemorrhagic disease of the newborn. Vitamin K plays an important role in blood clotting.
Babies usually have low levels of vitamin K for a variety of reasons. Vitamin K doesn't move easily across the placenta from the mother to the baby. As a result, a newborn doesn't have much vitamin K stored up at birth. Also, there isn't much vitamin K in breast milk.

Call your doctor if your baby has any unexplained bleeding.
It is recommended to give every baby a shot of vitamin K immediately after birth. This practice has helped prevent the condition.
The early onset form of the disease may be prevented by giving vitamin K shots to pregnant women who take anti-seizure medications.
