What is Asthma?
Asthma causes difficulty in breathing. This disease is caused in the airways of lungs where usually swelling or narrowing take place, leading to wheezing, shortness of breath, chest tightness, and coughing.
It is usually cause due to inflammation (swelling)Â in the airways. When the attack of this disease takes place, it becomes difficult for the air to pass through the linings of the lungs conveniently. This can greatly reduce the amount of oxygen that has to enter the blood circulation for proper growth and strength of the body.
