Pulmonary embolism is also referred to as PE. This disease – rather condition may be the better word over here – can be defined as one where a lung artery gets blocked all of a sudden. The blockage normally happens because of a blood clot that originates in the patient’s leg and then makes its way to the veins in the concerned person’s lungs. Such a clot is also referred to in medical lexicon as an embolus. This is a very serious condition as such and has the potential to damage parts of one’s lung and this happens because the lung tissue does not get proper blood flow because of said blockage.
The most evident sign that you are suffering from pulmonary embolism is shortness of breath for which you can never find any palpable reason as such. This also means that you experience problems in breathing and have issues such as chest pain and coughing. At times, you may cough up blood as well. Yet another sign of PE is arrhythmia or an irregular heartbeat. At times, you may also get only those signs and symptoms that can be linked to deep vein thrombosis (DVT) as well. In this case, your legs may swell.
It might also happen that you experience swelling along a vein located in your leg. There could be tenderness or pain in your legs as well. At times, the swollen or tender part of your leg could feel warm as well. At times, the affected part of your leg – or rather the skin on it – could get discolored or red as well. In case you experience any one of the symptoms that have been mentioned above it is always better to go and check with your doctor right away. Quite often it might also happen that you contract PE but you do not have any of the signs and symptoms that were stated above.
At times when people suffer from PE, they may also experience feelings such as dread and anxiety. At times they may feel lightheaded and faint as well; some other signs, in this case, are really quick breathing, a higher rate of beating heart and sweating as well.
Normally PE owes its origins to DVT. When the clot that has caused DVT unchains itself and travels to your lungs through your bloodstream it can block an artery as well.
There are several reasons as to why blood clots might form in the deep veins of your legs. In most cases, it happens because blood flow slows down and gets restricted. Normally, this happens because you are unable to move around because of some reason or the other and that too for a long period of time. Normally it could be so because you recently had a surgery or when you are on a long road trip or flight as such. It could also happen if you are bedridden for a really long period of time for some reason or the other.
