GLP-1 agonists (specifically Semaglutide and Liraglutide) induce significant weight loss (≥15%) which improves Obstructive Sleep Apnoea (OSA) severity, measured by Apnoea-Hypopnoea Index (AHI), particularly in patients who cannot tolerate CPAP.

If you have OSA and struggle with CPAP or cannot lose enough weight through diet alone, GLP-1 agonists like Semaglutide (2.4mg weekly) are a clinically proven option to reduce sleep apnea severity. Be prepared for potential gastrointestinal side effects and the likelihood that you may need to stay on the medication long-term to keep the weight off and your airway open.

GoodSupportsHIGH confidence
with high dose Semaglutide (Wegovy™) at 2.4 mg once weekly via subcutaneous injection in non-diabetic obese patients, over 50% of patients achieved and sustained at least a 15% weight loss... the SCALE Sleep Apnoea randomized controlled trial (RCT) demonstrated that Liraglutide improved AHI in OSA subjects unwilling or unable to use continuous positive airway pressure (CPAP).

Why this rating

Supported by RCT data (SCALE Sleep Apnoea) and high-dose trials for Semaglutide, though the paper notes direct evidence for OSA is still 'limited' and more trials are ongoing.
