GLP-1 receptor agonists (GLP-1RAs) may reduce the severity of Obstructive Sleep Apnoea (OSA) as measured by the Apnoea-Hypopnoea Index (AHI), primarily through weight loss mechanisms, though evidence quality is currently low and results are conflicting.
If you have OSA and are considering GLP-1RAs (like semaglutide or liraglutide), expect a modest improvement in sleep breathing (AHI) rather than a cure. The benefit is largely tied to weight loss. Do not stop using your CPAP machine unless your doctor advises it, as CPAP is currently more effective. Be prepared for potential stomach side effects, which are common but often subside. The evidence is not yet strong enough to make this a standard first-line treatment for OSA alone.
This scoping review identified early evidence to suggest that GLP-1RAs may improve OSA as defined by reduction in apnoea-hypopnoea index (AHI). This evidence is however conflicting due to contradicting results demonstrated from other studies.
Why this rating
The review explicitly states the evidence is 'low quality' with 'short lengths of follow-up' and 'conflicting results'.

- Bariatric surgery (VSG and RYGB) is the most effective and sustainable treatment for obesity, producing marked and sustained weight loss that non-surgical interventions cannot match.Strong
- Severely protein-deficient diets (2–3% energy) induce lean body mass loss and metabolic imbalance, whereas adequate protein intake (0.66 g/kg/d minimum) is a prerequisite for maintaining muscle, bone, and physiological function.Strong
- For patients with Class III obesity (BMI >39.9 kg/m2), metabolic bariatric surgery (MBS) is significantly more effective than any currently approved medication, with BilioPancreatic Diversion (BPD) showing the highest estimated weight loss.Strong
