Common Causes of Asthma and Ways to Control It

Asthma attacks may be triggered by various causes. When the body detects an irritant, the immune system immediately responds by releasing inflammatory substances to the area where the irritant is sensed. As a result swelling occurs and mucous is produced. When this occurs broncheo spasms result which cause severe breathing difficulties for asthma sufferers.

The local environment can be a big cause of asthma attacks. Bacteria and dust that exist where you live can become lung irritants. Some studies show that children who grow up spending most of their time indoors develop a weaker immune system compared to children who are encouraged by their parents to play in the open air. This makes them susceptible to bacteria and atmospheric particles found at home and elsewhere. Lower levels of resistance to outside pollutants then make them vulnerable to environmental dusts that can cause irritation and other complications.

Asthma may be developed because of an allergy. Common allergens that trigger asthma attacks include pollen, hair, animal dander, feathers, and molds. Diseases such as allergic rhinitis or hay fever may also trigger asthma. The severity of the attack largely depends on what allergen the patient has been exposed to. Food allergies may be a factor as well. Patients with asthma are highly advised to be careful with their diet because a food allergy has been known to trigger asthma attacks. Doctors recommend a diet wherein foods that usually cause allergy, like wheat, corn and dairy are omitted.
