Introduction
Clinical manifestations may include skin and mucosal bleeding, such as purpura, epistaxis, and gingival bleeding. Internal organ bleeding may present as hematemesis, hematuria, or menorrhagia, and in severe cases, intracranial hemorrhage may occur. Neonatal hemorrhagic disease commonly occurs 2–3 days after birth and is typically characterized by umbilical cord bleeding and gastrointestinal bleeding. Bleeding in this condition is usually mild, and hemorrhage into muscles, joints, or other deep tissues is rare.
The main symptom of vitamin K deficiency is bleeding.
Vitamin K deficiency, commonly known as vitamin K deficiency disorder, refers to reduced activity of vitamin K-dependent clotting factors caused by insufficient vitamin K, which can be corrected with vitamin K supplementation. It is primarily due to inadequate dietary intake, liver dysfunction, or use of oral vitamin K antagonists. Clinical manifestations may include skin and mucosal bleeding such as purpura, bruising, nosebleeds, and gum bleeding. Internal organ bleeding may present as hematemesis (vomiting blood), melena (black tarry stools), hematuria (blood in urine), or menorrhagia (excessive menstrual bleeding). In severe cases, intracranial hemorrhage may occur. Neonatal hemorrhagic disease typically occurs 2–3 days after birth and commonly presents with umbilical stump bleeding or gastrointestinal bleeding. Bleeding in this condition is usually mild, and muscular, joint, or deep tissue hemorrhages are rare.
In daily life, patients should consume more foods rich in vitamin K, such as spinach and other green vegetables. Patients suspected of vitamin K deficiency are advised to seek timely medical evaluation at a reputable hospital, undergo appropriate diagnostic tests, and receive targeted treatment under medical supervision to prevent disease progression.
