Users of GLP-1 medications like Ozempic and Wegovy are reporting a peculiar side effect known as “Ozempic breath,” characterized by a fishy odor in burps and bad breath.
GLP-1 medications, including Ozempic and Wegovy, are increasingly popular for managing diabetes and aiding weight loss. However, users are now raising concerns about a lesser-known side effect referred to as “Ozempic breath.” This phenomenon, which has gained traction on social media, is described as producing a fishy smell in burps or bad breath.
Dr. Neha Lalani, an endocrinologist based in Lakeway, Texas, explained that while gastrointestinal symptoms are commonly associated with GLP-1 medications, the emergence of “Ozempic breath” has caught many by surprise. Clinically known as halitosis, bad breath is not listed among the known side effects of popular semaglutide (Ozempic, Wegovy) and tirzepatide (Monjouro, Zepbound) medications.
The potential for this side effect is influencing consumer behavior. Recent reports indicate that the CEO of Hershey noted an uptick in sales of gum and mint products, suggesting that individuals are seeking ways to combat the unpleasant breath associated with these medications.
Despite the growing number of anecdotal reports, there is currently no peer-reviewed research that confirms a direct link between GLP-1 medications and bad breath or elucidates the underlying mechanism causing it. Nevertheless, many users have taken to social media to share their experiences with “Ozempic breath.”
One user expressed their frustration, stating, “This is mortifying lol. I even brushed my teeth and gargled with mouthwash and I’m [still] smelling it. It literally smells like a dirty drain or sewage.” Another user added, “I feel like I need to brush my teeth all the time. The sulfur burps were temporary but DISGUSTING.”
Dr. Sue Decotiis, a physician specializing in medical weight loss and hormone optimization in New York City, confirmed that bad breath can stem from various factors, including dehydration, gastric reflux, medication side effects, and imbalances in gut flora. She emphasized the importance of hydration, noting that even at moderate doses, GLP-1 medications require approximately a gallon of water daily to support fat metabolism and maintain proper hydration. “Very few patients do this or are advised to do so,” she remarked.
Decotiis also suggested that a well-balanced probiotic containing multiple species could be beneficial, particularly if reflux persists. Furthermore, she highlighted that adequate protein and fiber intake is essential for gastrointestinal health and promoting a healthy gut microbiome.
Some users have shared tips that they found helpful in alleviating the issue. One individual noted on Reddit, “My mouth feels, tastes, and smells better when I’m constantly drinking water.” Another user recommended cutting out greasy and processed foods from the diet, stating, “It should go away.” Others have found relief with antacids and fiber supplements.
For anyone experiencing persistent bad breath or unusual digestive symptoms while taking a GLP-1 medication, consulting a healthcare professional is advisable for evaluation and guidance on next steps.
