Hormonal

Both semaglutide and liraglutide cause gastrointestinal adverse effects (nausea, vomiting, diarrhea) which are the most common reason for drug discontinuation.

Expect gastrointestinal side effects like nausea when starting GLP-1 medications. These are common, usually mild, and tend to decrease over time. Slow titration can help manage them.
