Glp-1 (glucagon-like peptide-1) is a hormone primarily known for its role in glucose metabolism and insulin regulation. However, emerging research suggests that GLP-1 products like Wegovy, Ozempic, Saxendar, Zepbound and Mounjaro may also play a role in inflammation and conditions like dry eye syndrome.

Inflammation is a complex biological response that occurs in response to harmful stimuli, such as pathogens, damaged cells, or irritants. It is characterized by various immune responses, including the release of pro-inflammatory cytokines and the activation of immune cells.

Several studies have investigated the potential anti-inflammatory effects of GLP-1. One study published in the journal 'Diabetes, Obesity and Metabolism' found that GLP-1 receptor agonists, a class of medications used to treat type 2 diabetes, could reduce markers of inflammation in patients with diabetes. This suggests that GLP-1 may have anti-inflammatory properties that could be beneficial in the treatment of inflammatory conditions.

Dry eye syndrome is a common ocular disorder characterized by insufficient tear production or poor tear quality, leading to discomfort, visual disturbances, and inflammation of the ocular surface. Inflammation plays a central role in the development and progression of dry eye syndrome, contributing to symptoms such as redness, irritation, and blurred vision.

Recent research has explored the potential link between GLP-1 and dry eye syndrome. A study published in the journal 'Investigative Ophthalmology & Visual Science' investigated the expression of GLP-1 receptors in the ocular surface and found that they were present in the cornea and conjunctiva, suggesting a potential role for GLP-1 signaling in ocular health. Our own research at Toyos Clinic shows that dry eye patients taking these medications for weight control also notice an improvement in the frequency and severity of their symptoms. Many are able to reduce drops, medications and even get back in to contact lenses with the improvements seen.

Furthermore, preclinical studies in animal models have provided evidence that GLP-1 receptor agonists may have protective effects against dry eye-induced inflammation and corneal damage. These findings raise the possibility that GLP-1-based therapies could be explored as a novel approach for the management of dry eye syndrome.

However, more research is needed to fully understand the mechanisms underlying the potential effects of GLP-1 on inflammation and dry eye syndrome.
