Pulmonary embolism (PE) happens when a blood clot blocks an artery in your lungs. It can feel sudden and scary. Some have mild shortness of breath; others collapse. If you know the signs, you can get help faster and reduce the risk of serious harm.
Common symptoms include sudden shortness of breath, chest pain that gets worse when you breathe in, a rapid heart rate, lightheadedness, and coughing up blood. Pain or swelling in one leg before lung symptoms often points to a clot that started in the leg (deep vein thrombosis). Fever or sweating may show up too. Symptoms vary, so trust your gut if something feels seriously wrong.
Who is at higher risk? People after surgery, long flights or long bed rest, those with cancer, recent pregnancy, estrogen pills or birth control, obesity, or a history of clots. Older age and smoking raise risk. But younger people can get PE, especially if they have genetic clotting disorders or recent injury.
If you suspect PE, call emergency services right away. Don’t try to drive yourself if you feel faint or very short of breath. While waiting, sit upright and breathe slowly. Avoid taking medications unless a doctor told you to before. Quick hospital care makes a big difference.
Doctors will check oxygen levels, heartbeat, and remove life-threatening causes first. Common tests include D-dimer blood test, chest CT angiography, chest X-ray, and ultrasound of the legs. Pregnant patients or those with kidney issues may get alternative scans like a V/Q scan. A normal D-dimer makes PE less likely but not impossible.
Treatment depends on severity. Most patients get blood thinners (anticoagulants) to stop new clots and prevent growth. In severe cases with low blood pressure, doctors may use clot-busting drugs (thrombolytics) or remove the clot mechanically. Some people need an inferior vena cava (IVC) filter if anticoagulants are unsafe. Treatment length varies from three months to lifelong, based on cause.
After hospital discharge, follow-up matters. Take medicines exactly as prescribed, keep follow-up imaging if recommended, and learn signs of recurrence. Ask your doctor about lifestyle changes: stay active, lose weight, stop smoking, and discuss hormonal medications. For long trips, move every hour, do simple leg exercises, and drink water.
Prevention matters: after surgery or during long travel, compression stockings and short-term blood thinners can reduce risk. If you have a strong family history of clots, talk to a hematologist about testing and a prevention plan.
Ask questions about bleeding risks and what to do if you miss a dose. If you're pregnant or breastfeeding, tell your care team—some medicines change in pregnancy. Keep a list of current meds and avoid NSAIDs like ibuprofen while on blood thinners unless your doctor says it's ok. Carry a card saying you're on anticoagulants in case of emergency.
Pulmonary embolism can be treated successfully when caught early. If you feel sudden chest pain, breathlessness, fast heartbeat, or fainting, get emergency help now.
As someone who has experienced a pulmonary embolism, I understand the immense psychological impact it can have on an individual. The anxiety and fear one faces during and after such a life-threatening event are often overwhelming. It's important to recognize that these emotions are natural and valid. To cope with this anxiety and fear, seeking professional help, such as therapy or support groups, can be extremely beneficial. Remember, you are not alone in your journey to recovery, and together we can overcome the challenges posed by the psychological effects of a pulmonary embolism.
