Vitamin K deficiency in newborn infants is treated and prevented with a single injection of phylloquinone (5 mg).
Vitamin A deficiency can be prevented or treated by taking vitamin supplements or by getting injections of the vitamin.
Newborns are especially prone to vitamin K deficiency
Vitamin K deficiency in adults is rare
The prognosis for correcting vitamin K deficiency, and associated blood-clotting problems, is excellent.
Vitamin K deficiency can cause massive hemorrhaging in infants due to impaired blood clotting. This deficiency can occur because newborns have lower levels of vitamin K, which is needed for proper blood coagulation. Infants are typically given a vitamin K injection shortly after birth to prevent this deficiency.
Deficiency of Vitamin K
A vitamin K deficiency can be caused by a number of different things. Specifically, chronic diseases, like liver disease, can cause the vitamin not to be absorbed properly. Also, some medications like Aspirin can cause a vitamin K deficiency.

Vitamin B6 deficiency is typically treated by increasing intake of foods rich in vitamin B6, such as poultry, fish, beans, and bananas. In severe cases, vitamin B6 supplements may be prescribed by a healthcare provider. It's important to consult with a doctor for proper diagnosis and treatment.
Vitamin K is necessary for the production of Clotting Factors II, VII, IX and X. So a vitamin K deficiency could lead to a bleeding disorder. Additionally vitamin K is necessary for the production of the anticoagulant protein C and protein S. Inhibition of Vitamin K function is also associated with clotting disorders though for this to occur there has to be a deficiency in either proteins C or S.

Vitamin K deficiency is typically measured by assessing levels of prothrombin time (PT) and activated partial thromboplastin time (aPTT) in the blood. Additionally, measurement of vitamin K-dependent clotting factors, such as Factor II, VII, IX, and X, can also be used to diagnose deficiency. Specialized tests to directly measure vitamin K levels in the blood can also be performed.
