what causes fluid around your lungs?

Pleural effusion occurs when fluid builds up in the space between the lung and the chest wall. This can happen for many different reasons, including pneumonia or complications from heart, liver, or kidney disease. Another reason could be as a side effect from cancer.

What causes pleurisy? Most cases are the result of a viral infection (such as the flu) or a bacterial infection (such as pneumonia). In rarer cases, pleurisy can be caused by conditions such as a blood clot blocking the flow of blood into the lungs (pulmonary embolism) or lung cancer.

Sometimes in patients with heart failure, high pressures within the heart cause the fluid not to drain properly. The body, however, continues to produce pericardial fluid, leading to excess fluid around the heart (chylous pericardial effusion).

Put simply, chest congestion is a non-medical term for a build-up of fluids and mucus in the lungs. Your chest may feel heavy and stiff. There may be pain when you try to take a deep breath. You may, or may not, have a cough that produces mucus.

Acute respiratory distress syndrome (ARDS) occurs when fluid builds up in the tiny, elastic air sacs (alveoli) in your lungs. The fluid keeps your lungs from filling with enough air, which means less oxygen reaches your bloodstream. This deprives your organs of the oxygen they need to function.

An increase in blood flow across the hole to the lungs can cause the lungs to become congested. Congestion of the lungs interferes with their job of transferring oxygen from the air to the blood and carbon dioxide from blood to air.

In some disease processes, pulmonary edema is a common symptom of approaching death. In cardiac disease, such as congestive heart failure ("CHF"), edema may occur in the extremities or the lungs, depending on which half of the heart is weakened.

Pulmonary edema is often caused by congestive heart failure. When the heart is not able to pump efficiently, blood can back up into the veins that take blood through the lungs. As the pressure in these blood vessels increases, fluid is pushed into the air spaces (alveoli) in the lungs.

With pneumonia, the fluid in the lungs is filled with white blood cells trying to fight off the infection. With congestive heart failure, the fluid in the lungs is fluid that has leaked from the circulation due to a backup of blood in lung blood vessels.

Pulmonary Edema in Dogs. Pulmonary edema, the abnormal accumulation of fluid in the tissue, airways, or air sacs (alveoli) of the lungs, may occur along with circulatory disorders or in some allergic reactions or infectious diseases. Head trauma can cause pulmonary edema in dogs.

Pleural effusion, also called water on the lung, is an excessive buildup of fluid in the space between your lungs and chest cavity. Thin membranes, called pleura, cover the outside of the lungs and the inside of the chest cavity.

Pneumonia is an infection that inflames your lungs' air sacs (alveoli). The air sacs may fill up with fluid or pus, causing symptoms such as a cough, fever, chills and trouble breathing.

Pneumonia is swelling (inflammation) of the tissue in one or both lungs. It's usually caused by a bacterial infection. It can also be caused by a virus, such as coronavirus (COVID-19).

Chest X-rays can also reveal fluid in or around your lungs or air surrounding a lung. If you go to your doctor or the emergency room with chest pain, a chest injury or shortness of breath, you will typically get a chest X-ray.

A wet, productive cough produces sputum (phlegm or mucus from the lungs or sinuses). The cough sounds soupy and may come with a wheezing or rattling sound and tightness in your chest. Most wet coughs are caused by an infection: a common cold, the flu, bronchitis, or pneumonia.
54889
Pulmonary edema occurs when the alveoli fill up with excess fluid seeped out of the blood vessels in the lung instead of air. This can cause problems with the exchange of gas (oxygen and carbon dioxide), resulting in breathing difficulty and poor oxygenation of blood.

The lungs are covered by a thin tissue layer called the pleura. The same kind of thin tissue lines the inside of the chest cavity -- also called pleura. A thin layer of fluid acts as a lubricant allowing the lungs to slip smoothly as they expand and contract with each breath.
