Blood Clot Prevention: Effective Tips to Stay Safe

2. Varicose Veins, Redness, and Swelling in the Legs

Varicose veins, which happen most often in the legs, have a bluish-purple or red color. Many people also call them "spider veins," and they appear when you veins enlarge, dilate and overfill with blood. This overfilling weakens them, making them appear twisted just beneath the surface of your skin. The danger in having varicose veins is that the blood that flows through them moves slow. As a result, blood clots form. Fortunately, the blood clots that form from varicose veins do not travel to the lungs and cause a pulmonary embolism. However, it is something you and your doctor should watch closely. Although it is not common, an embolism is possible.
