The cause of asthma attacks and Description
Asthma is a chronic lung disease that causes inflammation in the airways, causing symptoms such as coughing, wheezing and shortness of breath. Anyone can have asthma, including infants and adolescents. The tendency to develop asthma usually have a hereditary basis.
Many children with asthma can breathe normally for weeks or months from one crisis to another. In general, crises happen without warning. In fact, flares usually evolve from time to time, which is a complex process of progressive airway obstruction.
All children with asthma have inflamed airways which means that they swell and produce lots of thick mucus. In addition, the airways of children with asthma are hypersensitive or hyperreactive, certain triggers.
When the muscles around the airways are exposed to these triggers, they often contract, which becomes even more narrow and clogged airways. The factors that trigger asthma attacks varies from person to person. Among the most common triggers include exercise, allergies, viral infections and smoke.
Therefore, the flare has three important changes that affect the respiratory system:
- swelling of the airway wall
- excess mucus that causes congestion and the formation of mucus plugs stuck in the narrowed airways
- bronchoconstriction, the contraction of the muscles around the airways
The sum of these three factors, swelling, excess mucus, and bronchoconstriction narrow the airways, which inhibits air travel (like when you breathe through a straw). During the flare, a child may experience coughing, wheezing (a whistling sound in the chest when breathing), chest tightness, rapid heartbeat, sweating and shortness of breath.

[...] The diagnosis of asthma can be a long and complicated process because not all children with asthma have similar symptoms. For example, some kids cough all night, but it seems fine in the daytime, while others suffer frequent chest colds that are difficult to cure. It is quite common that a child has these symptoms for months before I see a doctor. [...]
