Bariatric surgery and significant weight loss (>5%) improve asthma control, quality of life, and reduce systemic/airway inflammation in obese asthma patients.
Losing just 5% of your body weight can significantly improve your asthma biomarkers and quality of life. This can be achieved through surgery or structured lifestyle changes. If you have metabolic issues alongside obesity, you may need a more targeted approach, but weight loss remains a key strategy.
GoodSupportsHIGH confidence
Surgical techniques, such as Roux-en-Y gastric bypass and sleeve gastrectomy, are associated with reduction in both systemic and airway pro-inflammatory markers, improvement in lung function, asthma control and quality of life scores... loss of > 5% of body weight had a favourable impact on asthma biomarkers... and patient-centred outcomes.
Why this rating
Supported by multiple studies including prospective trials and meta-analyses, though some have limitations like small sample sizes.

More from this paper
- Obesity negatively impacts asthma outcomes and has a causal link in the pathogenesis of adult-onset asthma, primarily through a pro-inflammatory state driven by an imbalance in the adipose organ.Good
- Obesity reduces the accuracy of standard asthma biomarkers (FeNO, IgE, eosinophils), potentially leading to misclassification of asthma phenotype and inappropriate biologic eligibility.Good
