What potential impact does obesity have on asthma?

Obesity is associated with a variety of physiological changes, including increased inflammation, altered lung mechanics, and diminished respiratory function. These factors contribute to worsening asthma symptoms and can complicate overall asthma management. For instance, excess weight can lead to increased airway inflammation and may exacerbate reactive airway disease, making asthma attacks more likely.

Moreover, the presence of obesity can also affect the pharmacodynamics of asthma medications. Body weight and composition can influence how well medications are absorbed, distributed, metabolized, and eliminated from the body. As a result, individuals with obesity may experience decreased effectiveness of standard asthma treatments, necessitating adjustments in dosages or treatment strategies to achieve optimal control of asthma symptoms.

In contrast, other options present inaccuracies about the relationship between obesity and asthma. Some imply that obesity does not affect asthma at all or suggest improvements in asthma control, which contradicts the well-documented evidence that obesity can adversely influence asthma management and outcomes.
