Hemorrhagic disease of the newborn is a rare bleeding problem that can occur after birth. It’s classified according to the timing of its first symptoms as early onset, classic onset, or late onset.
The disease is caused by vitamin K deficiency.
As a result,
it’s often called vitamin K deficiency bleeding (VKDB).
To help boost their vitamin K levels, neonatal doctors usually give babies a vitamin K shot shortly after birth. This shot helps prevent VKDB.
