Pleural Effusion

Symptoms

• Shortness of breath: Excess fluid in the pleural space can put pressure on the lungs and make it difficult to breathe.
• Chest pain: The fluid in the pleural space can cause the chest to feel heavy or painful.
• Cough: Pleural effusion can cause a persistent or productive cough.
• Fatigue: The difficulty breathing and other symptoms of pleural effusion can cause fatigue.

Causes

• Pneumonia: An infection of the lungs, such as pneumonia, can cause fluid to build up in the pleural space.
• Lung cancer: Lung cancer can cause fluid to accumulate in the pleural space.
• Heart failure: When the heart is not able to pump efficiently, fluid can accumulate in the lungs and cause pleural effusion.
• Autoimmune disorders: Certain autoimmune disorders, such as lupus and rheumatoid arthritis, can cause inflammation and fluid accumulation in the pleural space.
• Medications and procedures: Certain medications, such as nonsteroidal anti-inflammatory drugs (NSAIDs) and chemotherapy drugs, and procedures, such as radiation therapy, can cause pleural effusion.

Risk factors

• Age: Older adults may be more at risk of pleural effusion due to the increased risk of underlying conditions such as pneumonia and heart failure.
• Gender: Men may be slightly more at risk of pleural effusion than women.
• Chronic health conditions: Certain chronic health conditions, such as lung cancer, heart failure, and autoimmune disorders, can increase the risk of pleural effusion.
• Smoking: Smoking can damage the respiratory system and increase the risk of pleural effusion.
• Medications: Certain medications, such as NSAIDs and chemotherapy drugs, can increase the risk of pleural effusion.
• Procedures: Procedures, such as radiation therapy, can increase the risk of pleural effusion.

Complications

• Shortness of breath: The excess fluid in the pleural space can put pressure on the lungs and make it difficult to breathe.
• Chest pain: The fluid in the pleural space can cause the chest to feel heavy or painful.
• Difficulty speaking or swallowing: The pressure from the pleural effusion can make it difficult to speak or swallow.
• Difficulty sleeping: The symptoms of pleural effusion, such as shortness of breath and chest pain, can make it difficult to sleep.
• Respiratory failure: In severe cases, pleural effusion can cause respiratory failure, a condition in which the lungs are unable to adequately oxygenate the blood.
• Sepsis: In rare cases, pleural effusion can lead to sepsis, a potentially life-threatening condition that occurs when the body's response to an infection damages its own tissues and organs.

How to diagnose it?

• Physical exam: A physical exam can help a healthcare provider assess your overall health and check for signs of pleural effusion, such as shortness of breath and chest pain.
• Chest X-ray: A chest X-ray can help a healthcare provider see the structure of your lungs and check for signs of pleural effusion, such as fluid in the pleural space.
• Ultrasound: An ultrasound can create images of the inside of the body using sound waves and can be used to detect pleural effusion.
• CT scan: A CT scan can create detailed images of the inside of the body and can be used to detect pleural effusion.
• Thoracentesis: In some cases, a healthcare provider may recommend a procedure called thoracentesis, which involves inserting a needle through the chest wall and into the pleural space to remove a sample of the fluid for testing.

How to prevent it?

• Get vaccinated: Vaccines are available to protect against certain types of pneumonia, which can be a cause of pleural effusion. These vaccines are especially important for people at high risk of pneumonia, such as older adults, very young children, and people with underlying health conditions.
• Avoid smoking: Smoking damages the respiratory system and increases the risk of pleural effusion. If you smoke, consider quitting to reduce your risk of developing the condition.
• Eat a healthy diet: A healthy diet can help boost your immune system and reduce your risk of infections, including pneumonia, which can lead to pleural effusion.
• Stay hydrated: Drinking plenty of fluids can help thin mucus and make it easier to cough up, which can help prevent pneumonia and pleural effusion.
• Manage chronic health conditions: If you have underlying health conditions, such as heart failure or autoimmune disorders, work with your healthcare provider to manage these conditions and reduce your risk of pleural effusion.

When do you need to see a doctor?

It is important to see a healthcare provider if you have any symptoms of pleural effusion, especially if you are at increased risk of developing the condition. Symptoms of pleural effusion can include shortness of breath, chest pain, coughing, and fatigue. 

It is especially important to see a healthcare provider if you have severe shortness of breath, chest pain that does not go away, or a persistent or productive cough. These symptoms can indicate a more serious case of pleural effusion that may require immediate treatment. 

If you have underlying health conditions, are over the age of 65, or have a weakened immune system, it is important to be extra vigilant about seeking medical attention for any respiratory symptoms, as you may be at an increased risk of complications from pleural effusion.
