A 2026 meta-analysis of 4 randomized trials found that GLP-1 receptor agonists reduced obstructive sleep apnea severity by 13.89 apnea-hypopnea events per hour compared with placebo, alongside 12.46 kg more weight loss than placebo.1 The effect looks clinically meaningful for obesity-linked sleep apnea, but high heterogeneity means the result should not be flattened into “GLP-1 …
Some sleep apnea patients stay sleepy even when their CPAP is used 6+ hours a night and apnea events have been driven back to normal range. A 2026 cross-sectional study of 65 PAP-adherent adults found those residually sleepy patients performed measurably worse on global cognition, memory, executive function, attention, and processing speed than their well-rested …
A 2026 secondary analysis of the HomePAP trial found that each 10 L/min more unintentional CPAP mask leak was associated with 26.6 fewer PAP minutes per night and 7.2 percentage-point fewer adherent days, but the new Real Leak metric did not significantly outperform ordinary device-reported Average Leak.1 Research Highlights Real Leak tracked poorer adherence: each …
