Symptoms and Signs of Vitamin K Deficiency
Bleeding is the usual manifestation. Easy bruisability and mucosal bleeding (especially epistaxis, gastrointestinal [GI] hemorrhage, menorrhagia, and hematuria) can occur. Blood may ooze from puncture sites or incisions. Hemorrhagic disease of the newborn and late hemorrhagic disease in infants may cause cutaneous, GI, intrathoracic, or, in the worst cases, intracranial bleeding. If obstructive jaundice develops, bleeding—if it occurs—usually begins after the 4th or 5th day. It may begin as a slow ooze from a surgical incision, the gums, the nose, or GI mucosa, or it may begin as massive bleeding into the GI tract.
