Treatment of vitamin K deficiency is based primarily on the patient’s condition and the severity of the bleeding. Vitamin K supplementation is sufficient if there are no symptoms of severe bleeding, while fresh frozen plasma transfusion is required if severe bleeding symptoms occur. Treatment of vitamin K deficiency should be altered based on the patient’s condition and severity of bleeding, and vitamin K can be given orally or by injection. Vitamin K can be given orally to patients with vitamin K deficiency and no bleeding, and vitamin K can be injected in patients with chronic vitamin K deficiency secondary to malnutrition. However, complications of severe bleeding, such as intracranial hemorrhage, must be corrected quickly. Although vitamin K is fast-acting, fresh frozen plasma should be injected prior to administration. Adequate fresh frozen plasma not only improves the symptoms of the condition, but also treats bleeding tendencies. Therefore, patients are advised to visit regular hospitals in time and choose the right way of treatment under the guidance of specialized doctors.
