Can GLP-1 medications cause insomnia or sleep changes?
The short answer: Trouble sleeping isn't a classic GLP-1 side effect, but some people notice sleep changes early on — often tied to digestion, nighttime reflux, or the stress of adjusting. Good sleep habits and managing reflux help most. This is not a classic side effect, but some notice sleep changes during adjustment.
Why it happens

Blood-sugar shifts and stress of adjusting play a role.

How long it lasts

Nutrition tips
