Related Disease Conditions
Emphysema is a COPD (chronic obstructive pulmonary disease) that often occurs with other obstructive pulmonary problems and chronic bronchitis. Causes of emphysema include chronic cigarette smoking, exposure to secondhand smoke, air pollution, and in the underdeveloped parts of the world. Symptoms of emphysema include chronic cough, chest discomfort, breathlessness, and wheezing. Treatments include medication and lifestyle changes.
Pleural Effusion (Fluid in the Pleural Space)
Pleural effusion is a buildup of fluid in the chest or the lungs. There are two types of pleural effusion, transudate, and exudate. Causes of transudate pleural effusion include congestive heart failure, kidney failure, and cirrhosis. Exudate pleural effusion can be caused by malignancy (cancer) or a lung infection. Typically, transudate pleural effusion is more easily treatable. Symptoms of pleural effusion include chest pain, pain when breathing, difficulty breathing, and cough. Treatment depends on the source or cause of the pleural effusion.
Pulmonary Embolism (Blood Clot in the Lung)
A pulmonary embolism (PE) occurs when a piece of a blood clot from deep vein thrombosis (DVT) breaks off and travels to an artery in the lung where it blocks the artery and damages the lung. The most common symptoms of a pulmonary embolism are shortness of breath, chest pain, and a rapid heart rate. Causes of pulmonary embolism include prolonged immobilization, certain medications, smoking, cancer, pregnancy, and surgery. Pulmonary embolism can cause death if not treated promptly.
How Serious Is a Blood Clot in the Lungs?
A blood clot is a solid or semisolid clump of blood. When the tissues of our body are injured, excessive blood loss is prevented by the clotting of blood. When a blood clot occurs inside the blood vessels it may lead to serious medical conditions. When a blood clot occurs inside the arteries to the lungs, the condition is called pulmonary embolism (PE).

The lungs are primarily responsible for the exchange of oxygen and carbon dioxide between the air we breathe and the blood. Eliminating carbon dioxide from the blood is important, because as it builds up in the blood, headaches, drowsiness, coma, and eventually death may occur. The air we breathe in (inhalation) is warmed, humidified, and cleaned by the nose and the lungs.
Popcorn Lung (Bronchiolitis Obliterans)
Popcorn lung is a term for the lung disease bronchiolitis obliterans. Popcorn lung is caused by diacetyl and 2,3-pentanedione, chemicals used when manufacturing flavorings for food certain products like popcorn, coffee. E-cigarettes also may cause popcorn lung. Diacetyl and 2,3-pentanedione damage lung tissue that is irreversible. Symptoms of popcorn lung develop gradually over time. The main symptoms are chronic cough and shortness of breath. Other symptoms may include night sweats, weight loss, and fever. Symptoms of severe exposure to diacetyl and 2,3-pentanedione include inflammation of the skin, eyes, nose, and/or throat. Popcorn lung often resembles tobacco-related COPD (chronic obstructive pulmonary disease) so it often is difficult to diagnose. Lung biopsy and surgery may be necessary. There is no cure for popcorn lung. Life expectancy for a person with (bronchiolitis obliterans) depends upon how early the disease was diagnosed and level of exposure to diacetyl and 2,3-pentanedione.
Interstitial Lung Disease (Interstitial Pneumonia)
Interstitial lung disease refers to a variety of diseased that thicken the tissue between the lungs' air sacks. Symptoms of interstitial lung disease include shortness of breath, cough, and vascular problems, and their treatment depends on the underlying cause of the tissue thickening. Causes include viruses, bacteria, tobacco smoke, environmental factors, cancer, and heart or kidney failure.
Collapsed Lung (Pneumothorax)
A pneumothorax is air in the chest outside the lung that causes the lung to collapse (collapsed lung). There are two types of pneumothorax, spontaneous or primary pneumothorax and secondary pneumothorax. Symptoms include sudden chest pain, shortness of breath, rapid heart rate, rapid breathing, cough, and fatigue.
Nontuberculous Mycobacterial Lung Disease (NTM, Symptoms, Treatment, Side Effects)
Nontuberculous mycobacteria (NTM), most commonly, M. avium complex or MAC, is a mycobacteria that causes lung infections and disease. Nontuberculous mycobacteria are commonly found in soil, air, and water. Examples of how NTM lung infection are transmitted include swimming, using a hot tub (NTM bacteria are aerosolized), or playing with or handling soil. The most common symptoms of NTM lung infection are chronic, dry cough, and shortness of breath. Sometimes the cough may have mucous or blood. Other symptoms of NTM lung disease include fatigue, chest pain, malaise, and weakness. As NTM lung disease progresses, fevers, night sweats, and appetite loss may occur. Treatment guidelines for NTM lung disease depend upon the type and extent of the infection, and the person's health.
Where Does Tuberculosis Come From?
Tuberculosis (TB) is an illness caused by a bacteria will get into your lungs and cause an infection there, but it can also attack other areas of your body, including your kidneys, brain, and spine. Tuberculosis (TB) is a disease that comes from a bacteria called Mycobacterium tuberculosis.
