Embolisms are medically relevant events that can cause serious damage to the body. In general, an embolism occurs when an obstruction, usually a clot, moves from one place in the body and lodges at another. The obstruction can travel through the bloodstream and block arteries, veins, and capillaries. This can cause serious damage to the organs and tissues that rely on them for blood flow. Depending on the type of embolism and what it attaches to, the consequences can range from mild to life-threatening. For example, a pulmonary embolism occurs when a clot travels to the lungs, which can make breathing difficult or impossible. Pulmonary embolisms can be extremely dangerous and can lead to heart failure, shock, and death. Meanwhile, cerebral embolisms can cause stroke-like symptoms, including sudden numbness and motor dysfunction. Embolisms can be caused by a variety of conditions and situations, such as weakened blood vessels, an injury to a large vessel, or a buildup of cholesterol in the arteries. In order to help prevent embolisms, people can use medications such as anticoagulants and antiplatelet drugs. Some lifestyle changes, such as eating a healthy diet and exercising, can also help reduce the risk of embolism. Therefore, it is important for individuals to be aware of their risk factors and take the necessary steps to protect themselves from these serious medical events.
