In a pooled comparison of 15 studies covering 1,877 overweight or obese people with moderate-to-severe sleep apnoea, GLP-1 drugs cut the apnoea-hypopnoea index by 15.28 events per hour versus placebo, lowered BMI by 1.78 points and nudged up blood oxygen levels. The evidence was rated moderate certainty at best, and comparisons against exercise were mostly indirect.
