Current literature indicates that asthma is more prevalent among obese individuals. In addition, studies have shown that higher body mass index (BMI), particularly BMI ≥ 30 kg/m2, is associated with poorer asthma control and asthma-related quality of life. Furthermore, growing evidence suggests that obese patients with asthma respond less favourably to inhaled corticosteroids compared to non-obese patients. Moreover, longitudinal studies indicate that weight reduction improves asthma control. Therefore, preventing and treating obesity should be an integrated part of asthma management.
