Causes and diagnosis of asthma
Asthma is a breathing disorder of the lungs in which the airways develop chronic inflammation, making breathing very difficult. Asthma has a very high prevalence rate in the country with approximately 27 million individuals being affected with the disorder. In asthma, the lining of the airways gets obstructed due to deposition and subsequent tightening of the mucus. This deposition adversely affects the air movement in the lungs and causes the classic symptoms of asthma, like coughing and tightness in the chest region. Symptoms of asthma Common asthma symptoms are wheezing, coughing during the night or during physical exercise, shortness in breath, and weakness. Causes of asthma A few important triggering factors and causes of asthma are described below: Allergy It has been reported that 75% of adults between 20-40 years of age also suffer from allergy. It shows that there is a link between asthma and allergic reactions. Smoking Smoking is directly linked with higher incidences of asthma. Moreover, its detrimental effects on airways augment the symptoms of asthma, such as shortness of breathing, excessive mucus production, and higher chances of infections. Obesity There are pieces of evidence that chronic inflammatory condition found in obesity is associated with asthma. Environmental factors Air pollution is one of the most important triggering factors for asthma attacks.
