Massive gastrointestinal bleeding due to vitamin K deficiency in a newborn

Early hemorrhagic disease of the newborn is a disease resulting from vitamin K deficiency, developing within the first 24 hours after birth. The disease may develop in babies born to mothers treated with anticonvulsants and antituberculous drugs, and sometimes as an idiopathic state despite prophylaxis with vitamin K. In this article, a case of early hemorrhagic disease in a newborn, presenting with a course of abundant gastrointestinal bleeding, has been discussed, who was born to mother with no risk factors and no history of drug use during pregnancy, with the disease onset in the first 24 hrs after birth despite administration of 1 mg vitamin K. With this article, we intended to point out that idiopathic early hemorrhagic disease may develop in newborns.
