Causes and Trigger Factors of Asthma

causes trigger factors asthma

Asthma is recurrent disease, which causes sufferers difficult to breathe due to narrowing of the airways. Nobody knows the exact cause of asthma. Asthma is often linked to allergies, but not all people with asthma have allergies.

However, the experts conclude that there are some common factors causing asthma =

  • Inflammation and the respiratory tract constriction.
    In a person with asthma, the inside walls of the respiratory tract become inflamed, making it vulnerable to irritation (swelling) and prone to asthma attacks. Irritation of the wall/the respiratory tract canal will make it narrower and harder for air flow (incoming or outgoing), resulting in difficulty breathing.
  • Environment.
    Living environment and lifestyle will affect the incidence of asthma. High exposure to pollutants (car exhaust, cigarette, etc.) has a close relationship with asthma attacks, especially in children. Poor air quality can be a strong factor causing asthma.
  • Genetic.
    Some people are born with the risk of carrying the disease of asthma, while in others not. Someone who has a family history of asthma had a greater risk of developing asthma. Experts continue to do research and find the relationship between asthma with genes that carried at birth.

Asthma triggers.

Asthma attacks come in different ways to different people. Similar to allergic reactions, asthma attacks would occur if the respiratory tract is in contact with one or more asthma triggers.

Things that include asthma triggers are =

  • Dust.
  • Pollen.
  • Mushrooms.
  • Fur.
  • Cigarette smoke.
  • Stress.
  • Physical activity.
  • Changes in weather.
  • Allergic reactions to some foods.
  • Certain medicines.
