causes of asthma  



Causes or triggers of asthma


There are various mechanisms that cause asthma  and vary among population groups and even individuals. It is seen that many asthma sufferers also have allergies. Not all people with allergies have asthma; however, not all cases of asthma can be explained by allergic response.

Asthma is most likely a result of genetic susceptibility, which probably involves several genes and various environmental factors.

An asthma attack can be induced by direct irritants (allergens or triggers) to the lungs such as:

  • House dust mite , specifically mite faces.

  • Pollen.

  • Molds and fungi.

  • Animal dander.

  • Cockroach.

  • Pollution.

  • Cigarette smoking can cause both asthma and COPD.

  • Food allergies.

  • Occupational triggers.

  • Exercise.

  • Infections.

  • Hormones.

  • Cold air.

  • Extreme emotions.

  • Drugs.

  • Gastro esophageal reflux disease (GERD).
