AI uncovers hidden Ozempic side effects across 400,000 Reddit posts
Researchers at the University of Pennsylvania used AI to analyze 400,000 Reddit posts to identify potential underreported side effects of GLP-1 weight-loss drugs. The study suggests that patient-reported data can provide valuable insights into symptoms like reproductive changes and temperature regulation issues.

This approach demonstrates how social media data can supplement clinical trials to improve drug safety monitoring and patient care.
Artificial intelligence is giving researchers a new way to listen to what patients are saying about popular GLP-1 drugs. After analyzing more than 400,000 Reddit posts, a University of Pennsylvania team identified several symptoms reported by people using semaglutide (Ozempic, Wegovy, and Rybelsus) and tirzepatide (Mounjaro and Zepbound) that may not be fully represented in clinical trials or official regulatory information.
The study, published recently in Nature Health , examined more than five years of posts from nearly 70,000 Reddit users. 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. Instead, researchers say the massive collection of spontaneous patient reports may reveal signals worth examining more closely.
