Bronchial Asthma, the most common cause for swelling in the airways and difficulty in breathing, is a very common lifestyle disease with definitive genetic roots. It is so common that it is estimated that 1 in 10 children or 10% of kids worldwide suffer from it. Even though many of them outgrow such childhood asthma, around 300 million people continue to be afflicted by it at any time, which is around 3.7% of the world population.
