Vitamin K Deficiency: Causes, Symptoms and Treatment

cured Vitamin K Deficiency

Vitamin K is a very important ingredient for growth of anyone and especially the infants. They are the ones more prone towards deficiency of Vitamin K which results in heavy bleeding caused by an inability to form blood clots. So, what is Vitamin K?

It comes in two forms, the first is known as the Vitamin K-1 or Phylloquinone and is generally found in plants such as spinach and Kale while the other is known as Vitamin K-2 or Menaquinone and is generally found in the body and gets created naturally in the intestinal tract. Both the forms produce proteins which help in the clotting or coagulation of the blood. This prevents excessive bleeding both internally and externally. While its deficiency is very rare, it occurs more in the infants known as VKDB. Its deficiency means a person’s body cannot produce enough of these proteins which increase the risk of excessive bleeding. Certain medications and medical conditions can reduce the production of Vitamin K and make our body deficient in it.

As illustrated earlier, certain medical conditions and medications impact the production of Vitamin K production. Some of the causes include the intake of anticoagulants which prevents blood clots but inhibit Vitamin K activation. Some antibiotics can also interfere with Vitamin K production and absorption. Due to adulteration, it might be that the supply of Vitamin K from the foods is inadequate or the person has taken more doses of Vitamin A or E which also affects adversely on the activation of Vitamin K.

This condition is known as Fat Malabsorption. People with that condition may also carry Celiac Disease or Cystic Fibrosis or an intestinal or Biliary Tract disorder or have part of their intestine removed.

These can arise from drinking breast milk which is low in Vitamin K or Vitamin K transfer from mother’s placenta to her baby has been altered.

Additional signs of excessive bleeding can also include easy bruising, small clots appearing under the nails, bleeding in mucous membranes that line areas inside the body. The stool may also get dark black, tar-like or may contain blood sometimes. While looking for signs of Vitamin K deficiency in newborn babies and infants, the doctors should look for bleeding from the area where the umbilical cord has been removed, bleeding in the skin, nose, gastrointestinal tract or other areas. The bleeding might also happen at the penis if the baby has been circumcised or sudden brain bleeds which are deemed severe and potentially life-threatening.


 The dosage given for the treatment depends completely on age and health of the individual. The usual dosage for adults might range from 1 to 25 mg of Phytonadione.
