Asthma, a chronic inflammatory disease that affects the airways, results in breathing problems that can make the lives of the patients terrible. A combination of environmental as well as genetic factors is understood to cause this problem. A spurt in asthma attacks overall has been witnessed in the past few years, which is being attributed to the changing environment and heritable factors.

The development and exacerbation of asthma is associated with certain environmental factors such as air pollution, allergens and chemicals present in the air. Traffic pollution and increased ozone levels in the air contribute to the development of the disease and worsening of its symptoms. Children of women who smoke during pregnancy are known to develop this disease.

Asthma patients complain of shortness of breath, chest tightening, coughing, and wheezing . These symptoms tend to worsen at night or during early morning.
