Abstract

Obesity is associated with more severe asthma that is less responsive to corticosteroids.

  • Obesity increases the risk of developing asthma and complicates its clinical management.
  • Asthma in obese individuals can exhibit altered respiratory mechanics and immune responses.
  • Glucagon-like peptide-1 receptor agonists may have anti-inflammatory and immunomodulatory effects that could benefit asthma treatment.
  • Early evidence suggests these medications might improve respiratory function in obese patients with asthma.
  • There is potential for a new approach to treating asthma by targeting metabolic dysfunction in patients with obesity.
