Asthma, one of the most widespread diseases, continues to be on the rise due to poor lifestyle, increasing pollution and unhealthy dietary habits. As per the World Health Organisation, approximately 15 to 20 million population of India suffer from asthma, that include patients from every age group. Asthma is a chronic respiratory disease which means it doesn't completely go away once a person develops it. When a person has asthma, they face difficulty in breathing as the bronchi or tubes carrying air to the lungs swell up. This happens due to the mucus inside bronchi coming into contact with an allergen, like dirt or a pollutant. Alarmingly, around 1.6 lakh asthma patients suffer from drug-resisting asthma, a stage described as 'severe asthma'. Some of the prominent causes of severe asthma include respiratory infections, smoke from tobacco, severe physical or emotional stress and environmental triggers. Therefore, patients suffering from severe asthma experience recurrent attacks and require frequent hospital visits.

Controlling Asthma Symptoms: Treating the Disease Based on Severity

The treatment of asthma majorly includes identifying the triggers of the patients, recognizing and managing their symptoms, and laying an action plan that can control a flare-up. Medications such as beta-agonists and combination inhalers are used to control inconsistent response of an allergen and reduce severe exacerbations giving patients a better quality of life. If one has an asthma flare-up, a quick-relief inhaler can come to the rescue by easing the symptoms instantly. For patients who do not respond to these medications or inhalers and have severe asthma, advanced technologies treatments such as Bronchial Thermoplasty (BT) help to reduce asthmatic attacks. It is a minimally invasive procedure that can only be carried on patients who are already on oral steroids for asthma exacerbations, the ones who use inhalers more than twice a week and the ones who have physical activity limitations due to asthma.

It is of utmost importance to understand the right management of the disease. Improper adherence to medication and treatment leads to poor asthma control, disease progression, and emergency hospital visits.
