One of the main causes of venous thrombosis in the lower extremities is the stagnation of blood flow in the lower extremities, which causes thrombosis. What is meant by stagnant blood flow is that when the body is kept in one position for too long, the blood flow is relatively slow and blood clots gradually form. In this case, some simple methods can be applied to prevent thrombosis, such as lifting the heel when standing or hooking the toe when lying down. Through the movement of the ankle joint, the contraction of the calf muscles is driven, and the contraction and relaxation of the calf muscles can promote the venous reflux and prevent the stagnation of venous blood flow and thrombosis in the lower limbs. In addition to these movements, slow walking and cycling can also be used to improve the stagnation of blood flow in the veins of the lower limbs. So in daily life you need to walk and exercise diligently to promote the venous reflux of the lower limbs, and you can also prevent the formation of venous thrombosis in the lower limbs by wearing varicose veins stockings.
