Vitamin K deficiency description:
The recommended daily allowance of vitamin K is 5 mg a day for infants, 65 mg a day for adult women and 80 mg a day for adult men. As it was mentioned before vitamin K plays a significant role in blood clotting and so without it even the smallest injury could cause continuous bleeding and lead to death.
Although vitamin K deficiency in adults is not very common due to its presence in many foods there are certain groups of adults who are more at risk. Those include people who take vitamin K antagonist anticoagulant drugs, as well as people with liver damage.
Newly born infants fed only by their mothers’ breasts are at risk of developing vitamin K deficiency as human milk is low in vitamin K.
Vitamin K deficiency leads to bruising easily, nosebleeds, bold in urine, tarry black stools and finally to impaired blood clotting.
