Vitamin K Deficiency Bleeding in the Newborn
What is vitamin K deficiency bleeding in the newborn?
Vitamin K deficiency bleeding is a problem that occurs in some newborns. It happens during the first few days and weeks of life. This condition used to be called hemorrhagic disease of the newborn. Vitamin K deficiency bleeding after the first 3 or 4 weeks of life is usually due to problems other than those listed here.
What causes vitamin K deficiency bleeding in the newborn?Babies are normally born with low levels of vitamin K. Vitamin K is needed for blood to clot. Not having enough vitamin K is the main cause of vitamin deficiency bleeding. If your baby’s blood doesn’t clot, he or she may have severe bleeding or a hemorrhage. This can be life-threatening.
Who is at risk for vitamin K deficiency bleeding in the newborn?
The following things may make it more likely for a baby to have this condition:
- Not getting a vitamin K shot at birth. The American Academy of Pediatrics recommends that all newborns get a vitamin K shot. This can prevent severe bleeding.
- Being breastfed only and not getting a vitamin K shot at birth. Breastmilk has less vitamin K than formula made with cow’s milk. The vitamin K shot will provide what a breastfed baby needs.
- Being born to a mother who took certain medicines during pregnancy. These include medicines for seizures (anticonvulsants) and medicines for blood clotting problems (anticoagulants).
What are the symptoms of vitamin K deficiency bleeding in the newborn?
Symptoms can occur a bit differently in each child. They can include:
- Blood in your baby's bowel movements
- Blood in your baby's urine
- Oozing around your baby’s umbilical cord
- Bruising more easily than normal. This may happen around your baby's head and face.
- Unusual, excessive sleepiness or fussiness. (In severe cases, vitamin K deficiency may cause bleeding in and around the brain.)
The symptoms of this condition may be similar to symptoms of other health issues. Make sure your child sees a healthcare provider for a diagnosis.
