Deep vein thrombosis (DVT) happens when a blood clot forms in a deep vein, usually in the legs. DVT can be dangerous because the clot can travel to the lungs and block blood flow, which can be fatal. Long flights increase your risk of DVT because sitting for long periods of time can slow down blood flow in your legs. There are a number of things you can do to help prevent DVT on long flights, including getting up and moving around every few hours, wearing compression stockings, and taking blood thinners.
It is important to take steps to prevent DVT on long flights, as it can be a serious condition. If you have any risk factors for DVT, such as a history of blood clots, talk to your doctor about taking additional precautions.
