US EditionUniversity of Pennsylvania Study Flags Underreported GLP-1 Side Effects on Reddit
AI analysis of 400,000 Reddit posts found reproductive and temperature-related complaints that were not prominent in clinical trials.
- Researchers from the University of Pennsylvania published a study in Nature Health using artificial intelligence to analyze over 400,000 Reddit posts, identifying patient-reported side effects of GLP-1 receptor agonists that clinical trials may have missed.
- While GLP-1 receptor agonists have soared in popularity for managing blood sugar and weight loss, adverse events remain a common cause of discontinuing the drug, with the MHRA previously highlighting gastrointestinal complaints.
- Of the nearly 70,000 users analyzed, 43.5 per cent reported at least one side effect, with nausea at 36.9 per cent, fatigue at 16.7 per cent, vomiting at 16.3 per cent, constipation at 15.3 per cent, and diarrhoea at 12.6 per cent.
- Lead author Neil Sehgal told Medical News Today that "nearly 4% of users who reported side effects mentioned menstrual changes," noting these reproductive symptoms are not prominently featured in current prescribing information.
- Researchers emphasize these findings do not prove causation, only that users reported symptoms while taking medications; the team hopes to expand future research beyond Reddit to include more diverse populations and English-language data.

Popular weight-loss medications linked to hidden side effects, study finds – Democratic Accent
In a sweeping analysis of more than 400,000 Reddit posts, researchers have revealed some little-known GLP-1 side effects.

A new study published in Nature Health, however, uncovered some overlooked effects. SHOULD YO…
