Hi Candidate,

Asthma is a breathing problem which causes Problem in inhalation and exhalation during breathing, because of problems in the Respiratory system.

Asthma is generally caused if a person is living in dusty surroundings and can be genetal too (transferred from parents to children). People suffering from Asthma use Nosal Inhalers and also undergo treatment, but none of them treats it completely or eradicates the problem.

Hope that this answer helps you.
