COPD
Chronic Obstructive Pulmonary Disease (COPD) is a group of lung diseases that obstruct airflow and make it difficult to breathe. Chronic bronchitis, emphysema, refractory (non-reversible) asthma and other progressive lung diseases are all in the category of COPD. Approximately 14.8 million adults have been diagnosed with COPD, and approximately 12 million people have not yet been diagnosed.
ASTHMA
Asthma is a respiratory condition that makes it difficult for a person to breathe, because of allergies or hypersensitivity(a very sensitive physical or psychological response). People with asthma have spasms in the bronchi of the lungs. When the airways react to substances that we breathe in the air, the muscles around the airways tighten, along with development of edema which narrows the airways and causes less air to flow into the lungs. Asthma causes wheezing (a whistling sound from your breathing), shortness of breath, coughing, and chest tightness. Currently more than 25 million people in the United States have asthma.
ACUTE BRONCHITIS
A chest cold, is often called acute bronchitis. A chest cold occurs when the airways of the lungs swell and produce mucus in the lungs. Acute bronchitis is an acute respiratory infection, manifested by cough with or without phlegm production. Acute bronchitis is usually caused by a virus. Bacteria can sometimes cause acute bronchitis.
LUNG CANCER
Cancer is a disease in which cells in the body grow out of control. When cancer starts in the lungs, it is called lung cancer. Lung cancer is the leading cause of cancer death and the second most diagnosed cancer in both men and women in the United States. Cigarette smoking is the number one cause of lung cancer. Lung cancer also can be caused by using other types of tobacco (such as pipes or cigars), breathing secondhand smoke, being exposed to substances such as asbestos or radon at home or work, and having a family history of lung cancer.
PULMONARY HYPERTENSION
Pulmonary hypertension is a rare disorder which is high blood pressure in the pulmonary arteries, which are arteries of the lungs. Shortness of breath, chest pressure, and dizziness are common symptoms of Pulmonary Hypertension. Some other symptoms may include, fatigue, swollen legs, fast heart rate, inability to exercise, or chronic cough. In Pulmonary Hypertension, your right side of heart works harder to pump blood through the lungs, because the increased resistance in pulmonary blood vessels.
