Asthma is a disorder that causes the airways of the lungs to swell and narrow, resulting into wheezing, shortness of breath, chest tightness, and coughing. While asthma is classified based on severity, at the moment there is no clear method for classifying different subgroups of asthma beyond this system.
The objective of asthma treatment is to control airway swelling. There are two basic kinds of medication for treating asthma:
Control drugs to prevent attacks
Quick-relief (rescue) drugs for use during attacks
Your doctor may suggest you an inhaler containing drugs to provide immediate relief. The main thing is that you would have to check for the elements that trigger asthma. Keep yourself away from those elements.
