AI analysis of 400,000 Reddit posts found that users of drugs such as Ozempic, Wegovy, Mounjaro, and Zepbound reported unexpected symptoms including menstrual changes, chills, hot flashes, and fatigue.
The short version
- Researchers cannot say the medications caused these problems, but the patterns may reveal overlooked signals worth studying.
- Artificial intelligence is giving researchers a new way to listen to what patients are saying about popular GLP-1 drugs.
- The study, published recently in Nature Health , examined more than five years of posts from nearly 70,000 Reddit users.
What happened
Two categories stood out as particularly deserving of further investigation: reproductive symptoms, including changes in menstrual cycles, and problems involving body temperature, such as chills and hot flashes. The findings do not establish that the medications caused these symptoms.
Why it matters
Instead, researchers say the massive collection of spontaneous patient reports may reveal signals worth examining more closely.
