Pulmonary embolism is a potentially life-threatening condition that occurs as a result of a blockage in the pulmonary arteries – the blood vessels that carry oxygenated blood from the heart to the lungs. The blockage is usually caused by a blood clot, which can originate in the deep veins of the leg, pelvis or even the arms, and then travel to the lungs.
Several factors can increase a person’s risk for developing pulmonary embolism. Some of these risk factors include:
1. Prolonged immobility: Extended periods of inactivity, such as being bedridden for an extended period, sitting for long periods, or being immobilized due to a medical condition, can increase the risk of blood clots forming in the legs and subsequently traveling to the lungs.
2. Surgery: Individuals who undergo major surgery, especially those involving the abdomen, pelvis, hip or knee, may be at an increased risk of developing pulmonary embolism due to the prolonged immobility and the stress related to surgery.
3. Trauma: Injuries to the legs, hips or pelvis can increase the risk of blood clots forming in the deep veins and subsequently lodging in the lungs.
4. Cancer: Some forms of cancer, particularly lung, pancreatic, and ovarian cancers, can increase the risk of developing blood clots in the veins, which may lead to pulmonary embolism.
5. Pregnancy: Pregnant women are at an elevated risk of developing blood clots due to hormonal changes, an increase in blood volume, and pressure on the veins from the growing uterus.
6. Hormonal therapy: Hormonal therapies such as birth control pills and hormone replacement therapy can increase the risk of developing blood clots, particularly in individuals who smoke, are overweight or have a family history of blood clots.
7. Age: The risk of developing pulmonary embolism increases as a person gets older, especially above the age of 60.
8. Genetic factors: A family history of blood clots can increase a person’s risk of developing pulmonary embolism.
9. Obesity: Being overweight or obese puts extra pressure on the veins in the legs, increasing the risk of blood clots forming.
Several factors can increase a person’s risk of developing pulmonary embolism, including prolonged immobility, surgery, trauma, cancer, pregnancy, hormonal therapy, age, genetic factors, and obesity. It is essential to be aware of these risk factors and take preventive measures when necessary to avoid developing this potentially life-threatening medical condition.

Can you get a pulmonary embolism for no reason?
Pulmonary embolism (PE) occurs when a blood clot (thrombus) travels to the lungs from another part of the body, often from the legs, and blocks a pulmonary artery or one of its branches. While in some cases a specific cause of pulmonary embolism may be identified, such as recent surgery, prolonged immobility, pregnancy, hormone therapy, or cancer, in other cases the cause may remain unknown, leading to the term “idiopathic”.
However, it is important to note that there is always a reason for pulmonary embolism, even if it is not immediately identifiable. The underlying cause may be multifactorial, involving a combination of factors such as genetic predisposition, blood clotting disorders, chronic illness, smoking, obesity, or a recent trauma.
Furthermore, it is possible for a blood clot to form spontaneously, without any known risk factors, especially in cases of deep vein thrombosis (DVT) or atrial fibrillation (AF).
Therefore, while it is rare for pulmonary embolism to occur without any identifiable risk factors, the absence of such risk factors does not necessarily mean there is no underlying cause. Regardless of the cause, the symptoms of pulmonary embolism should not be ignored, as they can be life-threatening and require prompt medical attention.
Symptoms of pulmonary embolism include shortness of breath, chest pain, coughing up blood, rapid heartbeat, and low blood pressure. Early diagnosis and treatment with blood thinners or clot-busting medications can improve the chances of survival and prevent long-term complications.
How do I prevent pulmonary embolism?
Pulmonary embolism is a serious medical condition caused by blood clots in the lung, which can be fatal. Preventing pulmonary embolism is essential to maintaining good health and avoiding this potentially life-threatening condition. Several measures can be taken to prevent pulmonary embolism, including lifestyle adjustments, medications, and medical procedures.
One of the best ways to prevent pulmonary embolism is by living a healthy lifestyle. It’s essential to maintain a healthy weight, exercise regularly, and eat a balanced diet to keep your body healthy and reduce your risk of developing blood clots. Additionally, avoiding smoking and limiting alcohol consumption can help reduce your risk of developing pulmonary embolism.
Another way to reduce your risk of pulmonary embolism is by taking medication regularly. Anticoagulants, also known as blood thinners, can help prevent blood clots from forming in your veins, thus reducing your risk of developing pulmonary embolism. However, it’s important to consult your doctor before taking any medication, as blood thinners can have side effects and may not be suitable for everyone.
If you’re at higher risk of developing pulmonary embolism, your doctor may recommend medical procedures to help prevent blood clots from forming. These procedures may include compression stockings, which apply pressure to your legs, encouraging blood flow and reducing the risk of clot formation. They may also include the use of an inferior vena cava (IVC) filter, a small device placed inside the vena cava vein to prevent blood clots from traveling to your lungs.
Finally, if you’re at high risk of developing pulmonary embolism, your doctor may recommend lifestyle modifications that support good health and reduce your risk of developing blood clots. For example, if you’re confined to working at a desk, your doctor may recommend regular breaks to move around and stretch your legs to improve blood flow.
Preventing pulmonary embolism requires a multi-faceted approach. This includes maintaining a healthy lifestyle and taking medication as prescribed, as well as undergoing medical procedures when necessary. By partnering with your doctor, you can take steps to reduce your risk of developing pulmonary embolism and live a healthy life.
What are the 5 strongest risk factors for DVT?
Deep vein thrombosis (DVT) is a serious condition that occurs when a blood clot forms in one or more of the deep veins in the body, usually in the leg. Several risk factors can increase a person’s chances of developing DVT, some of which are more potent than others. Here are the five strongest risk factors for DVT:
1. Surgery: Surgery, particularly major orthopedic surgeries, such as hip or knee replacement, increases the risk of DVT because it can slow down blood flow, cause blood vessels to become narrow, and damage the inner lining of the blood vessels. After surgery, patients may also experience immobility and be confined to bed, further increasing their risk of DVT.
2. Immobility: Prolonged periods of immobility, such as long-distance travel, bed rest after surgery, or being wheelchair-bound, increase the risk of DVT because it can reduce blood flow and cause blood to pool in the veins, which can lead to the formation of blood clots.
3. Age: As people age, the risk of developing DVT increases. This is because aging can lead to weaker blood vessels, impaired circulation, and other medical conditions that can increase the likelihood of a blood clot forming.
4. Family history: A family history of DVT and other clotting disorders can increase the risk of developing the condition. This is because certain genetic mutations can make the blood more prone to clotting.
5. Obesity: Being overweight or obese can increase the risk of DVT because excess weight can put extra pressure on the veins, leading to reduced blood flow and an increased risk of blood clots forming. Obesity is also associated with other conditions such as high blood pressure, diabetes, and high cholesterol, which are additional risk factors for DVT.
The five strongest risk factors for DVT are surgery, immobility, age, family history, and obesity. It’s important to keep these factors in mind and take steps to prevent DVT, such as staying active, maintaining a healthy weight, and taking precautionary measures before and after surgery or long periods of immobility.
Anyone who suspects they may be at risk for DVT should speak to their doctor about potential prevention strategies.
Does pulmonary embolism come on suddenly?
Pulmonary embolism, which occurs when a blood clot blocks an artery in the lungs, can sometimes come on suddenly, and sometimes it may develop more gradually. The speed at which symptoms of pulmonary embolism develop can depend on various factors, such as the size and location of the blood clot or clots.
In some cases, pulmonary embolism may occur suddenly and can lead to an immediate onset of symptoms. These symptoms can include sudden shortness of breath or difficulty breathing, chest pain or discomfort that worsens with deep breathing or coughing, rapid heartbeat, lightheadedness or dizziness, and coughing up blood or pink, frothy mucus.
If someone experiences any of these symptoms, they should seek immediate medical attention, as pulmonary embolism can be a life-threatening condition.
However, in other cases, pulmonary embolism may develop more gradually and may present with milder symptoms that are often overlooked or attributed to other conditions. These symptoms may include mild shortness of breath, fatigue, a cough that lingers for several weeks, or swelling in the legs or arms.
In some cases, pulmonary embolism may not present with any symptoms at all, which is known as a silent or asymptomatic pulmonary embolism.
It is important to note that while pulmonary embolism can sometimes come on suddenly, there are also many cases where it may develop gradually or not present with any symptoms. It is essential to be aware of the risk factors associated with pulmonary embolism, such as prolonged immobility, recent surgery or hospitalization, use of birth control, cancer, and history of blood clots.
Anyone with these risk factors, or anyone who experiences symptoms of pulmonary embolism, should seek medical attention immediately to receive prompt evaluation and treatment.
Will oxygen saturation be low with pulmonary embolism?
Yes, oxygen saturation can be low with pulmonary embolism. Pulmonary embolism is a serious medical condition where a blood clot, usually from a deep vein thrombosis (DVT) in the leg or pelvic veins, travels to the lungs obstructing the blood flow. This obstruction can lead to reduced oxygen supply to the body’s tissues resulting from a decrease in blood flow.
The extent of oxygen saturation reduction can vary depending on the location and size of the clot. If the clot obstructs a large pulmonary artery, a massive pulmonary embolism can ensue, causing severe respiratory compromise and a drop in oxygen saturation. Additionally, pulmonary embolism can lead to pulmonary hypertension and right heart failure, which also contribute to the decrease in oxygen saturation.
Furthermore, the clinical symptoms presented by patients with pulmonary embolism often include shortness of breath, cough, chest pain, and increased respiratory and heart rate. In severe cases, patients can suffer from syncope, hypotension, and even cardiac arrest. These symptoms further affect oxygen saturation as the body struggles to compensate for a reduced oxygen supply to the body’s tissues.
Oxygen saturation can be low with pulmonary embolism due to the obstruction caused by the blood clot in the lungs. Hence, early recognition of pulmonary embolism and prompt treatment is essential to minimize respiratory compromise and the risk of life-threatening complications.
