Asthma is a chronic condition of the respiratory system (lungs) in which a person’s air passages become inflamed, restricted, swollen, and produce a copious amount of mucus resulting in breathlessness, chest tightness, wheezing, and cough. Precisely it’s a common lung condition making airways sensitive and causing difficulty in breathing. It is also referred to as bronchial asthma. The condition worsens according to the amount of mucus produced as swelling of airways prevents oxygen from entering the lungs. As a result, oxygen doesn’t enter the bloodstream (called hypoxemia), and vital organs are deprived of oxygen.
The causes of the disease involve genetic and environmental factors. In some people, several triggers initiate an allergic inflammatory response of the airways like pollen, dust mites, air pollution, smoke, stress, etc.
The severity of the disease varies for everyone. Some people experience only minor attacks, while it can be extremely agonizing and even life-threatening for others. Several medicines are used to control the current symptoms and prevent future attacks. A person can lead a normal life by avoiding triggers and adhering strictly to the treatment regimes.
