Obesity-Related Asthma: Is Inflammation Driving Severity?
Research presented at the Francophone Congress of Allergology highlights the complex interactions between obesity and asthma, particularly obesity-associated asthma (OAA). The study indicates that OAA is characterized by increased severity and distinct clinical responses compared to other asthma phenotypes. Researchers emphasize the need for further investigation into the bidirectional relationship between obesity and asthma, as well as the implications for treatment.
- ▪Obesity-associated asthma (OAA) is a distinct phenotype influenced by immunity, metabolism, and respiratory mechanics.
- ▪Clinical observations show that OAA is more severe, with poor disease control and frequent exacerbations.
- ▪Obesity affects ventilatory mechanics and alters immune responses, particularly impacting innate immunity and corticosteroid sensitivity.

Obesity-associated asthma (OAA) is a distinct asthma phenotype shaped by complex, bidirectional interactions among immunity, metabolism, respiratory mechanics, and microbiome, according to research presented at the Francophone Congress of Allergology (CFA) 2026.Researchers examined how obesity and asthma may influence one another through multiple immune pathways, offering a new physiopathologic interpretation of this particularly severe and therapeutically challenging phenotype.The prevalence of both obesity and asthma has continued to increase over the past 50 years.
