Asthma is a chronic lung disease that inflames and narrows the airways. The causes of asthma are linked to several environmental and genetic factors. Exposure to certain allergens such as pollens, dust mites, tobacco smoke, air pollution, pets, chemicals from industries are attributed to asthma triggers. Certain drugs like aspirin and other anti-inflammatory drugs can cause asthma. The common symptoms of asthma include recurring wheezing, coughing, chest tightness, and shortness of breath.
The World Asthma Day takes place on the first Tuesday of May each year to spread awareness and care about the respiratory disorder around the world.
Asthma affects 300 million people globally. Every year about 250,000 people die of asthma prematurely around the world. It is estimated that asthma will grow by more than 100 million by 2025. 80% of asthma deaths occur in low-income countries. India has 20 million asthmatics, and the burden is higher than TB and HIV combined.
There is no cure for asthma. The best way to manage asthma is to avoid triggers, take medications to prevent symptoms and prepare to treat asthma episodes if they occur.
