What Causes Asthma? Facts You Never Knew

Asthma is a disease characterized by breathing difficulty in an episodic pattern. It is a long-term disease possibly lasting for the person’s entire life. The underlying mechanism responsible for the causation of asthma is inflammation of the airways.

Normally airways make sure to carry air in and out of the lungs. In case of asthma patients the airways are inflamed, which makes them narrow and swollen. This interferes with the process of delivery of oxygen to the lungs, thus causing breathing difficulty.
