Vitamin K deficiency

Vitamin K deficiency is uncommon in healthy adults. Vitamin K deficiency can be caused by taking anticoagulant drugs, liver damage or disease.

Vitamin K deficiency symptoms are:

• impaired blood clotting
• bruising
• bleeding (nosebleeds)
• blood in the urine
• blood in the stool
• heavy menstrual bleeding

Vitamin K deficiency can eventually lead to intracranial hemorrhage (life-threatening bleeding in the skull)
