Asthma causes the bands of muscle around the airways to become narrow. This makes it hard for enough air to pass through and for the person to breathe normally. It usually happens because of some triggers, or factors in the environment that cause a reaction.

Asthma also causes mucus-making cells inside the airways to make more mucus than usual and narrow the airways. During the oxygen fails to enter into the bloodstream and also the poisonous carbon dioxide could not leave the lungs and cause difficulty in breathing.


A variety of factors triggers different types of asthma. Some people experience occupational asthma, which is generally triggered by the environmental conditions around work area like chemical fumes, dust or other pollutants in the air. Some people experience shortness of breath during exercise as well.
