What is the primary cause of asthma?

The primary cause of asthma is linked to inflammation of the airways. In asthma, the airways become swollen and inflamed, which leads to symptoms such as wheezing, coughing, shortness of breath, and chest tightness. This inflammation is a hallmark of asthma and is triggered by various factors, including allergens, irritants, infections, and physical activity. While other elements like respiratory infections, air pollution, and genetic factors contribute to the severity and onset of asthma, the core issue driving the condition is the underlying airway inflammation. Consequently, reducing this inflammation is crucial for managing asthma effectively.
