What is the cause of Asthma?

Asthma is a lung condition that causes breathing problems. It is common in kids and teens and could be hereditary. It can be mild or so severe that it gets in the way of day to day life.

It all start in the passage way inside your lungs known as bronchi and bronchioles through which the air passes. These passages have an inner covering called the mucous membrane or mucosa surrounded by a layer of smooth muscles. Normally, when someone inhales, air goes in through the nose or mouth, down the windpipe called trachea, and into the airways of the lungs. And the mucus inside the passage ways helps to trap any outer particles like dust or pollen.

And when people with asthma are exposed to certain triggers like smoke, dust, pollen, colder climate etc. an asthma attack can occur, making it difficult for them to breathe. And that is because the smooth rings circling the air passages in the lungs tightens and narrows down. And at the same time, the dust particles cause mucosal lining to swell and produce lots of thick mucus that blocks the airways, making it harder for people with asthma to breathe. As they feel their chest tighten, making them cough uncontrollably due to swollen air ways, and they a wheezing sound as the air whistles while passing through the narrowed space.
