Asthma
Asthma is a chronic respiratory condition characterized by inflammation and narrowing of the airways, leading to difficulty breathing. It is often triggered by environmental factors like allergens (dust, pollen, pet dander), respiratory infections, exercise, or cold air. Asthma symptoms include wheezing, coughing, shortness of breath, and chest tightness. These symptoms can vary in severity, from occasional mild episodes to life-threatening attacks.
The underlying cause of asthma involves a combination of genetic and environmental factors. In asthma, the immune system overreacts to triggers, causing the airways to become inflamed and produce excess mucus, which narrows the air passages and leads to the characteristic symptoms.
