Wegovy Linked to Rare 'Eye Stroke' That Can Cause Sudden Blindness

Researchers found that Wegovy showed the strongest reported association with a rare optic nerve injury that can cause sudden vision loss, raising new questions about the safety of high-dose semaglutide formulations Men using Wegovy showed the highest reported risk in the FDA safety database, with odds of optic nerve injury appearing substantially higher than those reported for women Analysis of more than 400,000 online discussions revealed that many GLP-1 users frequently reported fatigue, low energy, menstrual changes, chills and hot flashes — symptoms that receive far less attention than digestive side effects Real-world patient conversations and artificial intelligence analysis are helping researchers identify emerging drug safety signals much faster than conventional reporting systems alone Your body already produces its own GLP-1 hormone through gut microbes that generate butyrate, and restoring this natural system through better gut health supports appetite control and metabolic function without relying on injections
