Woman develops stomach mass linked to GLP-1 use; diet cola reported as unusual remedy
A case report describes a woman who developed a mucus-covered stomach mass while taking a GLP-1 medication, with carbonated soda cited as the resolving agent.

A medical case report has drawn attention to a rare complication associated with GLP-1 receptor agonists, a class of drugs widely used for type 2 diabetes and weight management. According to the report, a woman developed a large, mucus-covered mass in her stomach after taking the medication, an issue that resolved after she consumed a significant amount of diet cola.
What happened in the case
The woman reportedly experienced persistent gastrointestinal symptoms, including bloating and discomfort, while on a GLP-1 therapy. Imaging revealed a sizable bezoar-like mass coated in mucus. Bezoars are accumulations of indigestible material that can form in the stomach and interfere with normal digestion. The case raises questions about how slowed gastric emptying, a known effect of GLP-1 drugs, may contribute to such buildups in susceptible patients.
Why carbonated soda worked
Doctors treating the patient turned to an unconventional intervention: having her drink large quantities of diet cola. The carbonation and acidity of the soda are believed to help break down the mass and encourage it to pass through the digestive tract. Within a short period, the mass reportedly cleared, and the woman's symptoms improved.
What this means for patients
While the outcome was positive, clinicians stress that the report should not be treated as general medical advice. Key considerations include:
- GLP-1 medications slow stomach emptying, which can occasionally contribute to bezoar formation.
- Unusual gastrointestinal symptoms while on these drugs should be evaluated by a physician rather than self-treated.
- Diet cola as a remedy remains a documented but uncommon approach in medical literature.
