Asthma is a respiratory disorder that involves inflammation in the lungs, leading to the narrowing of the airways. This narrowing makes it difficult for air to pass through and causes symptoms such as wheezing, coughing, and shortness of breath. The inflammation in the lungs can be triggered by various factors such as allergies, respiratory infections, and environmental irritants. Proper management and treatment of asthma aim to control inflammation, reduce symptoms, and improve lung function.
