Eye Stroke Risk Linked to Weight-Loss Injections
19 Mar
Summary
- Weight-loss injections carry a rare risk of 'eye stroke'.
- Semaglutide drugs like Wegovy show a stronger link to vision issues.
- More research is needed for safe dosages and vulnerable groups.
A rare side effect, termed 'eye stroke,' has been associated with popular weight-loss injections. This condition, medically known as non-arteritic anterior ischaemic optic neuropathy (Naion), occurs when reduced blood flow damages the optic nerve, leading to sudden vision loss in one or both eyes.
Recent analyses of reported side effects indicate a notable link between semaglutide, the active ingredient in drugs like Wegovy, and Naion. Wegovy showed a significantly higher association with eye stroke compared to other semaglutide treatments, despite fewer overall reported side effects.
Scientists are exploring how semaglutide, a GLP-1 hormone mimic that regulates blood sugar and digestion, might affect ocular blood flow. The faster weight loss induced by higher doses of injectables like Wegovy, and potential blood pressure fluctuations, are being investigated as contributing factors.
Further research is deemed essential to understand why men appear more vulnerable than women and to identify specific risk factors such as age or pre-existing conditions. Establishing safe dosage levels and conducting thorough clinical trials are critical for ensuring these widely prescribed treatments do not compromise patient eyesight.
