Identifying The Causes Of Asthma

The Causes of Asthma

  • Asthma is a long-lasting illness affecting the air passages in the lungs. The precise causes of asthma are still not known.
  • Though, asthma experts believe that a mixture of hereditary and ecological factors can cause asthma or at least make an individual sensitive to asthma triggers.
  • Though, no one actually knows why some individuals are affected by asthma, while others are not.
  • Allergies are also connected to asthma. But not all individuals who experience allergies get asthma.
  • While the causes of asthma are not fully known, doctors have recognized the main causes of asthma symptoms.

Asthma is a long-lasting illness disturbing the air passages in the lungs. The precise causes of asthma are still not known.

  • If you experience asthma, the lining of your airways become inflamed. This swelling makes the air passages very sensitive to certain triggers.
  • The swelling may constrict the air passages which makes it hard for air to go through the airways.

Tightening Of The Airway

  • To further confuse things, when the airways are triggered by certain allergens, the muscles surrounding the airways constrict.
  • This means the air passages become even thinner and gives you a taut feeling in the chest, like a cord is being squeezed around it.
  • Phlegm can get stuck in the constricted airways, causing more breathing problems.

Asthma Triggers

  • The triggers that cause the swelling and airway restriction can differ with each person.

Asthma triggers consist of:

  • Pet hair;
  • Heartburn or acid reflux;
  • Allergic response to food;
  • Pollen;
  • Tobacco smoke;
  • Breathing infections (such as the cold);
  • Fluctuations in weather (particularly cold air);
  • Anxiety and strong reactions;
  • Exercise and physical movement;
  • Mold;
  • Dust mites and cockroaches; and
  • Certain medicines (aspirin).
