Asthma is a chronic disease in the airways of the lungs. The cause of asthma is unknown. However, experts believe, asthma, genetic and environmental factors (eg family history of viral infections in infancy and early exposure to allergens) can cause asthma or fewer people who are sensitive to asthma triggers. But no one knows why some people with asthma and others do not. Allergies are often associated with asthma. However, not all allergic people have asthma. Although the causes of asthma are not known, doctors discovered two major reasons why the symptoms of asthma: Inflammation
If you have asthma, the mountain – or wall – inflammation of the airways (or swelling). This makes the airways sensitive to causing irritation and inflammation in asthma. swelling of the airways narrow, making it difficult for air (oxygen) through the airways and inhibit breathing in and out.

To further complicate the situation, some contact with water, asthma, the respiratory muscle around the airways narrow. This makes the airways narrow, and even provide a sense of tightness in the chest as the rope tightened around him. Mucus in the airways that leads to the granting of loss can breathe better.
The trigger that causes inflammation and narrowing of the airways can vary for different people. What is known is that, if the airway is associated with one of the many factors that cause asthma, inflammation, mucus, cut and fill. increase in respiratory mucosa, leading to a narrow airway.
