Deep vein thrombosis, or DVT, is a condition in which a blood clot (also called a “thrombus”) forms in the deep veins of the body, particularly in the legs. While some folks are predisposed to clotting because of blood diseases, others may need to be careful because certain of risk factors, like birth control, pregnancy, recent surgery, or a sedentary lifestyle. Blood thinners and anticoagulants can help control DVT, but they're not for everyone. Luckily, certain dietary changes may be able to prevent the development of blood clots.
One of the most important aspects of a DVT diet is staying hydrated. Less water in your body means less fluid in your blood—and when your blood doesn’t have the liquid it needs, it gets thicker. This makes clot formation even easier than normal. Most recommendations suggest somewhere in the neighborhood of six to eight cups of water each day for the average person. However, on hot days or days when you're more active, you need to replace all that sweat with extra water.
