GLP-1 injections and similar medications that have become a popular weight loss trend may threaten eye health. Serious risks are involved especially for individuals with diabetic retinopathy.

Ozempic, Mounjaro and similar GLP-1 injections used recently for weight loss provide weight reduction by suppressing appetite. However, these drugs should not be used solely for the purpose of losing weight. Particularly in patients with diabetes, they may rapidly worsen the course of eye diseases such as retinopathy. Even in people without diabetes, rapid weight loss may lead to changes in blood sugar and fluid balance, causing dry eyes, blurred vision and rarely problems with intraocular pressure. Side effects such as headache, nausea or vomiting in some individuals may also affect eye health indirectly. If you notice sudden changes in vision, blurriness or flashes of light, it is vital to stop the medication and consult an eye specialist immediately. Experts emphasize that use for weight loss without medical supervision is risky and that eye examinations should not be neglected especially in terms of eye health. Remember that although rapid weight loss may seem attractive, doctor supervision and regular eye examinations are essential in order not to put your eye health at risk.
