Asthma is the condition when the airways in lungs swell up, narrow down, inflame and produce mucus causing obstruction for air exchange in the lungs and breathing difficulty. In healthy airways, fresh air comes to alveoli and releases used air to exhale freely. On the other hand, air cannot move freely through the lungs in Asthmatic airways. Mucus blocks the airways and makes it difficult for oxygen to pass through the lungs to alveoli to ensure the necessary supply.
According to World Health organization (WHO), 263 million people affected by asthma in 2019 and caused almost 461000 deaths. It is a major noncommunicable disease (NCD) and most common chronic condition among children.
There are majorly three types of Asthma such as cough variant asthma, allergic asthma and non-allergic asthma. The symptoms of asthma are intermittent and are often worse at night, in winter and during exercise. There are many “triggers” for Asthma varying person to person such as smoke, dust, cold, fumes, strong soaps and perfumes, animal fur and features, grass and tree pollens.
There are two major types of inhalers such as bronchodilators (such as salbutamol) and steroids (such as beclometasone), regular use of inhalers helps to control disease and enable people to live normal daily life. In addition, regular breathing exercise can help you to increase lung capacity to get more fresh air. Asthma cannot be cured permanently but symptoms can be treated and controlled with proper asthma medications in large extent.
