12Other Risk Factors
In addition to these causes, there are some other risk factors for pulmonary embolism. Harmful substances in tobacco products would make it easier for blood to clot. Thus, it is important to stop smoking immediately. Being overweight or obese can also increase the possibility, especially in women. In general, pregnancy can be a risk factor for this condition because the weight of the baby would press on the veins around the pelvis. This can slow down the returning of blood from the legs, thus causing blood clots. [12]
