Learn about the causes, symptoms, treatment and prevention of blood clots in lungs, including pulmonary embolism and deep vein thrombosis (DVT).


Blood clots in lungs, or pulmonary embolism, can be a serious and life-threatening condition. This article aims to provide a comprehensive understanding of what pulmonary embolism is, why it happens, how it is diagnosed and treated, and how to prevent it from happening. This article is intended for individuals who want to learn more about pulmonary embolism or those who may be at risk of developing this condition.

Understanding Pulmonary Embolism: Causes, Symptoms and Treatment Options

Pulmonary embolism occurs when a blood clot travels from elsewhere in the body, most often from the leg, through the bloodstream and becomes lodged in the pulmonary artery. This blocks the blood flow, leading to reduced oxygen supply to the body and potentially severe complications. Causes of blood clots in lungs include:

  • Deep vein thrombosis (DVT) in the leg
  • Recent surgery, particularly lower extremity or pelvic surgery
  • Immobilization, such as prolonged bed rest or long-distance travel
  • Cancer or cancer treatments
  • Smoking
  • Pregnancy and childbirth
  • Heart disease
  • Inherited blood-clotting disorders

Symptoms of pulmonary embolism can range from mild to severe, and may include:

  • Sudden onset of shortness of breath
  • Chest pain, especially upon taking a deep breath
  • Cough, sometimes with bloody sputum
  • Rapid or irregular heartbeat
  • Dizziness or feeling lightheaded
  • Excessive sweating
  • Fever

If you are experiencing any of these symptoms or think you may be at risk of pulmonary embolism, seek medical attention immediately. Diagnosis of pulmonary embolism typically involves a combination of imaging tests and blood tests. Treatment options vary depending on the severity of the condition and may include blood-thinning medications and procedures to remove the blood clot.

Blood Clots in Lungs: Recognizing the Signs and Risks

It can be difficult to differentiate between symptoms of pulmonary embolism and other respiratory conditions, so it’s important to know the risk factors and warning signs of blood clots in lungs when assessing your own health. It’s particularly important to be aware of the following risk factors:

  • Recent hospitalization or surgery
  • Long periods of sitting or bedrest
  • Smoking
  • Medical history of blood clots
  • Pregnancy or recent childbirth
  • Cancer or cancer treatment
  • Obesity
  • Air pollution

Symptoms of blood clots in lungs include those of pulmonary embolism, as well as leg pain or swelling. If you experience any of these symptoms, it’s important to seek medical attention right away.

How to Prevent Blood Clots from Forming in Your Lungs

There are several lifestyle changes and habits you can adopt that may help prevent blood clots from forming in your lungs:

  • Stop smoking if you are a smoker
  • Maintain a healthy weight
  • Avoid prolonged sitting or standing
  • Exercise regularly
  • Stay hydrated
  • Take medication as prescribed, especially blood thinners

If you are at higher risk of developing blood clots due to factors such as surgery or pregnancy, your doctor may prescribe preventive medication.

The Connection Between DVT and PE: What You Need to Know

Deep vein thrombosis (DVT) is a blood clot that forms in a deep vein, most commonly in the leg. If a blood clot in the leg breaks off and travels to the lungs, it can cause pulmonary embolism. There are several treatment options for DVT, including:

  • Anticoagulants, also known as blood thinners
  • Thrombolytic therapy, which dissolves the clot with medication
  • Surgery, in severe cases where a clot is causing serious damage

It’s important to be aware of the signs and symptoms of DVT and take preventative measures, such as exercising regularly, wearing compression stockings, and taking blood-thinning medications if prescribed by a doctor.

What Every Person Should Know About a Pulmonary Embolism

There are several misconceptions about pulmonary embolism that can make it difficult for individuals to recognize when they are at risk. Below are some important facts about pulmonary embolism:

  • Pulmonary embolism is very serious and can be life-threatening
  • Symptoms of pulmonary embolism can be difficult to distinguish from other respiratory issues
  • Pulmonary embolism can happen to anyone, regardless of age or overall health
  • Early detection and treatment are crucial for a successful recovery
  • Preventative measures are key, such as maintaining a healthy lifestyle and avoiding prolonged periods of sitting or bedrest

Don’t Ignore These Warning Signs of Blood Clots in Your Lungs

It’s important to be aware of the possible warning signs of blood clots in your lungs and to seek medical attention immediately if you experience any of these symptoms:

  • Sudden shortness of breath
  • Chest pain or discomfort
  • Cough, sometimes with bloody sputum
  • Rapid or irregular heartbeat
  • Lightheadedness or dizziness
  • Fainting
  • Leg pain or swelling

How to Recover from a Pulmonary Embolism: Tips and Advice for Better Healing

If you have experienced a pulmonary embolism, your doctor will likely provide instructions for recovery and follow-up care. Here are some tips for healing and reducing your risk of future blood clots:

  • Take medications as prescribed, including blood thinners
  • Follow a healthy diet and exercise regularly
  • Avoid activities that may increase the risk of blood clots, such as long periods of sitting or standing
  • Attend follow-up appointments with your doctor
  • Ask your doctor about any concerns or questions you may have


Blood clots in lungs, also known as pulmonary embolism, can be a very serious condition with potentially life-threatening consequences. However, early detection and preventative measures can significantly increase the chances of a successful recovery. By understanding the symptoms, risk factors, and treatment options for blood clots in lungs, it is possible to take steps towards a healthier, safer life.
