What are potential consequences of untreated asthma?

Untreated asthma can lead to significant and lasting consequences for lung health, particularly through the mechanism of permanent airway remodeling and reduced lung function. When asthma is not adequately managed, chronic inflammation occurs in the airways. Over time, this persistent inflammation can result in structural changes, such as thickening of the airway walls and increased mucus production, which narrow the airways and make breathing more difficult.

These changes can permanently alter lung function, leading to a persistent reduction in airflow and making it challenging for individuals to breathe effectively even after an asthma attack has been managed. This can also increase the frequency and severity of asthma attacks over time. Therefore, the focus on managing asthma effectively is crucial to prevent these irreversible alterations in lung structure and to maintain optimal respiratory health.
