Asthma Causes

We do not know exactly what causes asthma.

What all people with asthma have in common is chronic airway inflammation and excessive airway sensitivity to various triggers.

Research has focused on why some people develop asthma while others do not.



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

The environment you live in and the way you live partly determine whether you have asthma attacks. An asthma attack is a reaction to a trigger. It is similar in many ways to an allergic reaction.

An allergic reaction is a response by the body's immune system to an "invader."

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

It is this series of reactions that causes the production of mucus and bronchospasms. These responses cause the symptoms of as asthma attack.

In asthma the "invaders" are the triggers listed below. Triggers vary by the individual.

Because asthma is a type of allergic reaction, it is sometimes called reactive airway disease. Each person with asthma has his or her own unique set of triggers. Most triggers cause attacks in some people with asthma and not in others. Common triggers of asthma attacks are the following:

Exposure to tobacco or wood smoke

Breathing polluted air

Inhaling other respiratory irritants such as perfumes or cleaning products

Exposure to airway irritants at the workplace

Breathing in allergy-causing substances (allergens) such as molds, dust, or animal dander

An upper respiratory infection, such as a cold, flu, sinusitis, or bronchitis

Exposure to cold, dry weather

Emotional excitement or stress

Physical exertion or exercise

Reflux of stomach acid - What medical professionals call gastroesophageal reflux disease, or GERD

Sulfites - An additive to some foods and wine

Menstruation: In some, not all, women, asthma symptoms are closely tied to the menstrual cycle. Risk factors for developing asthma

Hay fever (allergic rhinitis) and other allergies - The single biggest risk factor

Eczema - Another type of allergy affecting the skin

Genetic predisposition - A parent, brother, or sister also has asthma

Bronchodilators


Bronchodilators are medicines that help open the bronchial tubes (airways) of the lungs, allowing more air to flow through them.

Bronchoscopy


Bronchoscopy allows a doctor to examine inside your airway for any abnormality such as foreign bodies, bleeding, a tumor, or inflammation. The doctor uses either a rigid bronchoscope or flexible bronchoscope.

Respiratory System


Respiratory System, in anatomy and physiology, organs that deliver oxygen to the circulatory system for transport to all body cells. Oxygen is essential for cells, which use this vital substance to liberate the energy needed for cellular activities.
