Warfarin is a pill that you take regularly to help prevent blood clots or to keep a clot from getting bigger. Coumadin is the common brand name for warfarin.To ensure that warfarin is effectively thinning your blood, it's important to eat about the same amount of vitamin K every day. Vitamin K normally helps your blood clot so wounds don't bleed too much. Warfarin works against vitamin K, making your blood clot more slowly. So warfarin and vitamin K work against each other in your body. That is why, when you take warfarin, it's important that you not suddenly eat a lot more or a lot less vitamin K-rich food than you usually do.How to get a steady amount of vitamin KIt's up to you how much vitamin K you choose to eat. For example, if you already eat a lot of leafy green vegetables, that's fine. Just keep it about the same amount each day. And if you take a multivitamin that contains vitamin K, be sure you take it every day. Check with your doctor before you make big changes in
Blood clots can happen in veins. A blood clot in a vein close to the skin isn't likely to cause problems. But having blood clots in deep veins is called deep vein thrombosis. Deep vein thrombosis happens most often in the legs. This problem can lead to a blood clot in the lung (pulmonary embolism).The deep veins of the leg have different terms to describe their location:Upper (proximal) leg veins are those above the knee but below the waist. Popliteal veins are located behind the knee.Iliac and femoral veins are in the groin area.Lower (distal) leg veins are those below the knee. Distal leg veins are located in the calf and ankle.A person with a blood clot in a deep upper (proximal) leg vein is at increased risk for a blood clot in the lung or other complications.
A d-dimer test is a blood test that measures a substance that is released when a blood clot breaks up. Doctors order the d-dimer test, along with other lab tests and imaging scans, to help check for blood-clotting problems. A d-dimer test can also be used to check how well a treatment is working.
