Asthma is a lung disease resulting in difficulty breathing, especially at the end. Several mechanisms are responsible for this symptom. The bronchial inflammation causes contraction of muscles that surround and swelling of the inner wall of the bronchi. This is called bronchoconstriction (decrease in the diameter of the bronchi). The inflammation also causes increased secretion of mucus abundant. It is for these reasons that the air is hard to pass. It is the most common chronic disease in children, with 10% of children suffer.


Asthma and allergies:


People with asthma usually have an allergic: they have an excessive immune reaction in contact with a foreign agent called "allergen" (pollen, mold, dust).


Nearly 80% of asthmatics also suffer from allergic rhinitis, more commonly known as hay fever and rhinitis these can degenerate into asthma.

Both disorders that result in inflammation of the respiratory mucosa are related: the inhalation of the allergen causes a decrease in the diameter of the bronchi and may cause long-term alterations in bronchial mucosa, where inflammation chronic bronchi.

The incidence and severity of asthma depends on the degree of exposure to allergens, hence the interest of identifying and eliminating the substances to which a person is sensitive. Desensitization avoids the appearance of other allergies and asthma transformation.


Treatments for asthma:


The disease is mild, moderate or severe, asthma has the sole purpose of improving the quality of life of patients. We distinguish between treatments crisis, intended to relieve the symptoms and treatment of substance intended to space the occurrence of crises. However, 40% of patients neglect their therapy. Treatments have evolved over 20 years with the advent of inhaled corticosteroids are very effective for treating inflammation and traditional products combining bronchodilators with corticosteroids.


Asthma and Sports:


If untrained asthmatics may suffer from crises during exercise (called exercise-induced asthma), the sport is not prohibited or discouraged for people with asthma, provided they do follow their treatment and take some precautions.

To avoid attacks, it is recommended to follow a simple warm-up time and practice activity in good conditions, in particular by avoiding periods of high pollution, pollen dissemination or dry cold.
The practice of an indoor sport has the advantage of reducing such risks.
