Hello! Pulmonary embolism is a serious medical condition that occurs when a blood clot, usually from the legs, travels to the lungs and blocks an artery. It can be life-threatening if not treated quickly. Pulmonary embolism is caused by a variety of factors, including deep vein thrombosis (DVT), which is a blood clot in the leg; long periods of inactivity, such as after surgery or during a long flight; certain medications; and certain medical conditions such as cancer. The symptoms of pulmonary embolism can vary depending on the size and location of the clot. Common symptoms include shortness of breath, chest pain, rapid heart rate, coughing up blood, and lightheadedness. If you experience any of these symptoms, it is important to seek medical attention immediately. Diagnosis of pulmonary embolism typically involves imaging tests such as CT scans or MRI scans to look for clots in the lungs. Blood tests may also be used to look for signs of clotting disorders or other underlying conditions that may have caused the pulmonary embolism. Treatment for pulmonary embolism typically involves anticoagulant medications to prevent further clots from forming and breaking up existing clots. In some cases, surgery may be necessary to remove large clots or repair damaged arteries in the lungs. It is important to take steps to reduce your risk of developing pulmonary embolism by staying active and avoiding long periods of inactivity; wearing compression stockings if you are at risk for DVT; and talking with your doctor about any medications you are taking that could increase your risk for developing blood clots. If you think you may have pulmonary embolism or are experiencing any symptoms associated with it, it is important to seek medical attention right away as it can be life-threatening if not treated quickly.
