Asthma is a respiratory disease that causes difficulty in breathing. In asthma, there is inflammation of the airways due to which the respiratory tract becomes narrower (shrinks). Due to the narrowing of the respiratory tract, problems such as lack of breath, chest tightness and cough occur during breathing. The effect of asthma is different on different people. It is less problematic for some people, while other may face a lot of trouble because of it.

Depending on the symptoms, there are two types of asthma - external and internal asthma.
