Chronic obstructive pulmonary disease COPD is a type of obstructive lung disease in which chronic incompletely reversible poor airflow (airflow limitation) and inability to breathe out fully (air trapping) exist. The poor airflow is the result of breakdown of lung tissue (known as emphysema) and small airways disease (known as obstructive bronchiolitis).

Non-Small Cell Lung Cancer Treatment (PDQÂ®)âPatient Version Non-small cell lung cancer is a disease in which malignant (cancer) cells form in the tissues of the lung. There are several types of non-small cell lung cancer. Smoking is the major risk factor for non-small cell lung cancer.

Chronic obstructive pulmonary disease Chronic obstructive pulmonary disease (COPD), also known as chronic obstructive lung disease (COLD), and chronic obstructive airway disease (COAD), among others, is a type of obstructive lung disease characterized by chronically poor airflow. It typically worsens over time.

- Chronic obstructive pulmonary disease (COPD) is the term used to describe chronic lung conditions that cause severe shortness of breath and block the airways in your lungs. Usually it refers to long-lasting bronchitis or emphysema. But it can also include asthmatic bronchitis (bronchial asthma).

Overview Foreign body. Atelectasis is common in children who have inhaled an object, such as a peanut or small toy part, into their lungs. Narrowing of major airways from disease. Chronic infections, including fungal infections, tuberculosis and other diseases, can scar and constrict major airways. Tumor in a major airway.

- Asthma. A chronic lung disease that causes inflammation and narrowing in the airways, asthma is a must-include in a list of respiratory diseases. Symptoms of asthma include wheezing (characterized by a whistling sound while breathing), tightness in the chest, shortness of breath, and coughing.

emphysema A chronic disease in which the tiny air sacs in the lungs become stretched and enlarged, so that they are less able to supply oxygen to the blood. Emphysema causes shortness of breath and painful coughing and can increase the likelihood of developing heart disease.

Ghost stories: why the Victorians were so spookily good at them Ghost stories: why the Victorians were so spookily good at them. Christmas Eve was traditionally the time to tell scary stories round the hearth. Curl up by the fire and I'll tell you a ghost story. Don't be alarmed by the creak of the floorboards, the murmurs in the basement, the shrill ululations of a distant dog.

Atelectasis Atelectasis (/ˌætᵻˈlɛktəsᵻs/ uses combining forms of atel- + ectasis, from Greek: ἀτελής, incomplete + ἔκτασις, extension) is the collapse or closure of a lung resulting in reduced or absent gas exchange. It may affect part or all of a lung.

pulmonary disease Obstructive disease is characterized by reduced expiratory flow rates and increased total lung capacity. Acute obstructive respiratory diseases include asthma, bronchitis, and bronchiectasis; chronic obstructive diseases include emphysema, chronic bronchitis, or combined emphysema and chronic bronchitis.

Interstitial Lung Diseases Interstitial Lung Diseases. Interstitial lung disease is the name for a large group of diseases that inflame or scar the lungs. The inflammation and scarring make it hard to get enough oxygen. The scarring is called pulmonary fibrosis. Breathing in dust or other particles in the air is responsible for some types of interstitial lung diseases.

Tobacco-Related Diseases Emphysema. Emphysema (em-fe-ZEE-ma) is a chronic lung disease in which the air sacs of the lungs are overly large. This condition makes the lungs work less efficiently and leads to shortness of breath. About 2 million Americans have emphysema, and most of these cases are caused by smoking.

Asthma Asthma is a common long term inflammatory disease of the airways of the lungs. It is characterized by variable and recurring symptoms, reversible airflow obstruction, and bronchospasm. Symptoms include episodes of wheezing, coughing, chest tightness, and shortness of breath. These episodes may occur a few times a day or a few times per week. Depending on the person they may become worse at night or with exercise. Asthma is thought to be caused by a combination of genetic and environmental factors.

emphysema Emphysema is defined as a medical condition where there is air in body tissues or where the air sacs in the lungs are damaged in a way that causes shortness of breath. A medical condition caused by years of smoking that damages the air sacs in your lungs and makes breathing hard is an example of emphysema. emphysema. emphysema.

Asthma Asthma. Asthma is a chronic inflammatory disease of the airways. The disease manifests as recurrent attacks of wheezing, coughing and shortness of breath. During an asthma attack, the muscles surrounding the airways contract, limiting the amount of air supply to the lungs. The lack of sufficient air supply results in a choking sensation.

Reactive airway disease [edit on Wikidata] Reactive airway disease is a group of conditions that include reversible airway narrowing due to an external stimulation. These conditions generally result in wheezing. Conditions within this group include asthma, chronic obstructive pulmonary disease, and viral upper respiratory infections.

Emphysema Causes and Treatments Emphysema: Definition. Emphysema is a chronic lung disease caused by damage to the alveoli, the tiny air sacs in the lung where the exchange of oxygen and carbon dioxide takes place. With emphysema, damage to the alveoli results in air becoming trapped, causing them to expand and rupture.

Medical Dictionary of Health Terms: A-C Asthma is a chronic disease that affects the airways that carry oxygen in and out of the lungs. If a person has asthma, the inside of these airways is irritated and swollen. Asthma can cause shortness of breath, wheezing, coughing, and tightness in the chest. Asthma is a major chronic health problem for children.

- Asthma and Reactive Airway Disease (RAD) (Wheezing) Asthma and Reactive Airway Disease (RAD) are conditions in which the airways (bronchi) in the lungs overreact to certain things. Understanding what the lungs look like and how they work will help you understand asthma or RAD episodes and how to control them.

What is Restrictive Airway Disease and what causes it? Restrictive lung diseases are characterized by reduced lung volumes, either because of an alteration in lung parenchyma or because of a disease of the pleura, chest wall, or neuromuscular apparatus.

emphysema A disease in which the alveoli (tiny air sacs) of the lungs are damaged. Their separating walls are destroyed and the alveoli are enlarged. This leads to a decrease in the surface area available for gas exchange, and breathing becomes very difficult.

About Asthma Asthma is a chronic, or long-term, disease that inflames and narrows the airways of your lungs. Asthma causes a variety of symptoms that can worsen at any time, making breathing difficult. Asthma is a disease that cannot be cured, but it can be managed. Some days you may not have symptoms, but this doesn’t mean your asthma has gone away.

- Restrictive lung disease is a chronic disorder that causes a decrease in the ability to expand the lung (breathe in) and sometimes makes it harder to get enough oxygen to meet the body's needs.

Byssinosis Definition. 1  Byssinosis is a chronic, asthma-like narrowing of the airways. Also called brown lung disease, byssinosis results from inhaling particles of cotton, flax, hemp, or jute.
