People with multiple risk factors for blood clots are at increased risk of clots compared to people with only one risk factor. Because people with several risk factors need special consideration, it is normal for healthcare professionals to perform a complete evaluation when a patient experiences their first blood clot.
This is particularly important for children. Additionally, warfarin should not be used during pregnancy because it may harm the growing fetus. Talk to your doctor about your treatment plan if you are pregnant or planning to become pregnant.
The body needs vitamin K to produce some essential blood clotting factors. Without enough vitamin K, these clotting factors may still be produced but are ineffective in clotting.
Therefore, people with too little vitamin K have a bleeding tendency. Warfarin interferes with the action of vitamin K and therefore prolongs the time it takes to form a clot.
This is the intended effect of this therapy. Increasing vitamin K intake while you are on warfarin will work against the action of this medication. It is very important to keep the amount of vitamin K in your diet the same while on warfarin. Click here to sign up. Download Free PDF. Sylvie Perreault. A short summary of this paper.
