GLP-1 receptor agonists are associated with a rapid worsening of diabetic retinopathy, particularly in patients with a history of retinopathy and those using insulin, likely due to rapid glycemic improvement.
If you have diabetes and are starting a GLP-1 medication, ensure you have regular eye exams. If you already have eye problems, your doctor may monitor you more closely, as rapid blood sugar improvement can temporarily worsen vision.
ModerateSupportsMEDIUM confidence
a meta-analysis of 13 RCTs revealed that GLP-1 RAs... are associated with a 23% increased risk of rapid worsening of diabetic retinopathy in T2DM
Why this rating
Supported by RCTs and meta-analyses, but real-world data is heterogeneous and mechanisms are not fully clear.

- Initial treatment for type 2 diabetes should be a combination of metformin and either an SGLT-2 inhibitor or a GLP-1 receptor agonist to achieve cardiorenal protection, rather than monotherapy or older agents like sulfonylureas.Strong
- For patients with specific monogenic obesity syndromes (leptin deficiency, POMC/PCSK1/LEPR mutations), targeted pharmacotherapy (recombinant leptin or setmelanotide) is highly effective and should be prioritized, unlike in polygenic obesity.Strong
- Continued weekly administration of 2.4 mg subcutaneous semaglutide prevents weight regain and promotes further weight loss in adults with overweight or obesity, whereas switching to placebo results in significant weight regain.Strong
