New AI-based research reveals GLP-1 side effects missed in clinical trials

Key Points:

• Researchers at Penn Engineering used AI to analyze 400,000 Reddit posts to identify side effects of GLP-1 drugs that may be underreported in clinical trials, focusing on self-disclosed user experiences.
• Commonly reported side effects such as nausea, vomiting, and constipation aligned with clinical trial data, but the study also uncovered less frequently reported issues like menstrual irregularities (4% of users) and temperature-related symptoms like chills and hot flashes.
• Patient discussions on Reddit and social media revealed additional side effects including hair loss, extreme exhaustion, and injection site rashes, highlighting the value of patient communities in sharing real-world drug experiences.
• Experts emphasize the need for further scientific investigation into these side effects, with the online patient community potentially driving more comprehensive research and validation.
• Researchers are also monitoring discussions around Retatrutide, an experimental weight loss drug by Eli Lilly not yet approved globally, with concerns about unregulated online acquisition and microdosing practices emerging on Reddit.
