Pulmonary embolism or blood clots in the lungs is a problem which occurs when one or even more arteries in the lungs are blocked. In many cases, blood clots in the lungs are caused by clots of blood that flow to your lungs from another area of the body most frequently your legs. Blood clots in the lungs can happen in people who are otherwise healthy. Symptoms and signs can vary from individual to individual, but normally include unexplained and sudden shortness of breath, pains in the chest and a cough that can bring up sputum that is blood tinged.
Blood clots in the lungs can be life threatening but treatment which is prompt using anti-clotting drugs can reduce greatly any risk of death. Taking actions to stop blood clots from forming in the legs also can help to protect an individual against pulmonary embolism or the clot from moving from the leg to the lungs. Blood clots in the lungs have symptoms that may vary significantly, contingent on how much of the lung is involved, the clot size and a person’s general health, especially the existence or absence of any fundamental heart or lung disease.
