Causes Of Asthma

The exact cause of asthma is unknown.

That all people with asthma have in common is a chronic inflammation of the airways and airway sensitivity to different factors too.

The research focused on why some people develop asthma and others do not.

Some people are born with a tendency to have asthma, while others are not. Researchers are trying to find the genes that cause this trend.

The environment in which they live and how they live, in part, to determine if you have asthma attacks.

An asthma attack is a response to a trigger. It corresponds in many ways to an allergic reaction.

An allergic reaction is a reaction to the body's immune system to "Invader".

When cells of the immune system, the sense of an invader, they trigger a series of reactions that help fight the invader.

And 'this series of reactions that causes mucus production and bronchospasm. These responses lead to symptoms of an asthma attack.

When asthma is the "invaders" triggers listed below. Triggers vary among individuals.

Because asthma is an allergic reaction, sometimes called reactive airway disease.

Everyone with asthma has its own unique set of triggers. Most of the triggers cause attacks in some people with asthma and others do not. Common triggers of asthma attacks are as follows:

snuff or exposure to wood smoke,

breathing polluted air,

inhalation of other respiratory irritants such as perfumes or cleaning products,

exposure to respiratory irritants at work,

respiratory allergy-causing substances (allergens) such as mold, dust or animal hair,

an upper respiratory infection, such as colds, flu, sinusitis or bronchitis,

exposure to cold weather and dry

emotional arousal or stress,

physical exertion or exercise

acid reflux disease known as gastroesophageal reflux disease or GERD,

sulfites, an additive for food and wine, and

periods: in some, not all women have asthma symptoms closely related to the menstrual cycle.

Risk factors of developing asthma:

hay fever (allergic rhinitis) and other allergies - this is the single risk factor;

Eczema: a different type of allergy affecting the skin, and

genetic predisposition, a, sister, parent or sibling also has asthma.
