Asthma Attacks are caused by:
Cramps (spasms) in the muscle that surrounds the airways (bronchial)
Increased production of viscous mucus
Swollen mucous membranes
Damage to the epithelial cells
New immune cells that exacerbate the disease process
All of these disease mechanisms caused by the immune cells in the mucosa release biochemical substances.
The disease causes an inflammation of the bronchial mucosa. Untreated, this inflammatory process, cause the muscles grow and the bronchial tubes may be permanent damage, with chronic constriction of the airways that results.
Asthma Attacks can be triggered by allergic reactions, and of various substances that irritate the airways, flying dust, cigarette smoke, harmful gases (such as diesel long, sulfur dioxide and nitrogen oxides), cold, raw and cold weather, climate change of clothes, respiratory infections and physical exertion, especially in cold weather.
SYMPTOMS
Asthma Attack trigger varying degrees of heavy breathing, wheezing, coughing, and a feeling of congestion of the chest. The cough can be dry, but usually is accompanied by tough mucus coughed up. The symptoms can be difficult to distinguish from bronchitis and prolonged colds.
Attacks can be brief, a few minutes or hours, but can also last for several days, so-called status asthmaticus. It is typical that the discomfort is worse in the night and early morning.
