If your blood gets "too thick" then you are more at risk of clotting. If your blood gets "too thin" than you are more at risk for hemorrhage.

There are things that you can do to help keep your INR were it needs to be. One of these would be through diet and watching the amount of vitamin K that you eat, drink or take in your daily vitamins. Vitamin K is important because it helps the blood to clot. So this would make vitamin K a coagulant, which is also one of functions of factor five. Although when you inherit the FVL mutation and APC resistance this can cause you to produce abnormal clotting. The mutated site on the factor five gene makes these clots harder to break down and get out of circulation. Both factor five and vitamin K are produced in the liver. Both circulate in our blood stream. Warfarin works in our liver to decrease the amount of blood clotting factors that the liver produces. In turn we will have less clotting factors circulating in our blood stream. So, taking in too much vitamin K will do two things: it will decrease your INR and put you more at risk for abnormal clotting. The important thing to remember here is that you can have some vitamin K. The trick is to eat small amounts and be consistent with how much you eat. Do not go for long periods of time with no vitamin K and then binge on it. It is all about consistency. Talk with your Doctor about what amount might be good for you. Here are some of the foods that you need to limit; soybean oil, green tea, alfalfa sprouts, peas, blueberries, kiwi, kidney beans, spinach, green onions, all lettuce, broccoli, asparagus, beef liver, kale, apricots, cucumber, pea pods, watercress, brussel sprouts, avocado, potatoes, red cabbage, dill pickles.

Another thing to keep in mind is how much of the natural anticoagulants that you eat. This would be things that help thin your blood out such as: ginger, onion, garlic, Ginkgo Biloba, ginseng and purple grapes. Of all of these the purple grape is the strongest of the natural anticoagulants, if you eat the seeds and the skin with the grape. So, you would also want to watch how much purple grape juice that you drink.

Too much vitamin K will decrease the effectiveness of Warfarin and too much of the natural anticoagulants will increase the effectiveness of it. The trick is to find your balance, not every ones will be the same. Eat small amounts, be consistent and discuss your diet with your Health Care Provider.
