Asthma is a chronic respiratory condition that affects the airways, causing them to narrow and making it difficult to breathe. This narrowing is caused by inflammation, swelling, and production of extra mucus in the airways, which leads to symptoms such as wheezing, coughing, shortness of breath, and chest tightness. Asthma is a highly variable condition and can range from mild to severe, with symptoms that can be occasional or persistent, and can change over time. Asthma is typically treated with a combination of medications and lifestyle changes aimed at managing symptoms, preventing exacerbations, and improving overall lung function.
