What causes vitamin K deficiency in people?

What causes vitamin K deficiency in people?

Diet or Antibiotics: The vast majority of our vitamin k is actually produced by symbiotic bacteria in our intestines. So, if one has recently had a bout of heavy antibiotic use (which kills off both "good and "bad" bacteria in the body), then vitamin k deficiency can result. Poor diet can also lead to this deficiency. A deficiency in vit. K most often results in easy bleeding/hemorrhage susceptibility. ...Read more

What causes vitamin K deficiency in a baby?

What causes vitamin K deficiency in a baby?

Diet/ gut germs: Vitamins are something we need we can't make ourselves & for vitamin k there is a special step. Intestinal bacteria help convert ingested k precursors to the active form we need. Since newborns have no gut germs at the start, it takes a while to start the process. That is why babies get a v k shot at birth to bridge the ~ 8 days it takes for the process to kick in. ...Read more

Clotting factors: Vitamin k is used to create several factors in the clotting cascade (the system that ends in a blood clot).

K deficiency to prevent coagulation may begin spontaneously hemorrhaging elsewhere (particularly in the GI tract or the brain); and if the hemodynamic state in the body is disrupted, the heart may still become ischemic. ...Read more

Has it been looked into if an abundance of vitamin K in the blood causes autism? I know the study was of a deficiency of the vitamin.  Thank you.
