Gastric Bezoar treated with Diet Coke

What I get from this is that regularly drinking some soda should prevent the formation of gastric bezoars in the first place.

Gastric bezoars are masses that form in the stomach. There are different kinds depending on what the masses are made of. The most common is a phytobezoar, which is made from clumped fruit and vegetable components, particularly non-digestible materials such as cellulose. A notable subtype of phytobezoar is the diospyrobezoar, which is formed from eating an excessive amount of persimmons. The fruit's skin is brimming with tannins that form a glue-like substance when they hit gastric acid, aiding the formation of a mass that is notoriously hard and difficult to treat.

To see if the woman had a bezoar, doctors dropped an endoscope into her stomach and, sure enough, got close-up imaging of a large, greenish, gooey-looking mass covered in mucus in her stomach. It wasn't blocking her stomach, but it was definitely taking up a lot of space and causing problems.

Methods for getting rid of a bezoar include surgically removing it or using an endoscopic procedure to break it into small pieces so it passes through the stomach. But, in recent years, doctors have started treatments with a gentler approach, trying first to dissolve it with chemicals. And the go-to chemical is, surprisingly, Coca-Cola.

According to an editorial published last year in the World Journal of Gastrointestinal Endoscopy, the idea of using Coca-Cola for bezoars is thought to be based "on its acidic properties and the presence of carbonic and phosphoric acids, which can help break down the fibrous material in phytobezoars." The authors of the NEJM case report, however, highlight that the bezoar-busting properties of Coca-Cola are not entirely understood.

Regardless, the editorial authors signal that Coca-Cola has become a first-line treatment for bezoars, and several case reports and studies support its use. A 2024 randomized controlled trial involving 160 patients in China with phytobezoars concluded that "Timely ingestion of Coca-Cola yields significant benefits, including a complete dissolution rate of 100 percent, a low incidence of gastric ulcers, no need for fragmentation, and reduced expenses."

...

While it's unclear what the woman's bezoar was made of—she didn't report eating an excessive amount of persimmons—it was most likely some type of phytobezoar. As such, doctors put her on a plan to drink 3,000 milliliters (about 8.5 cans) of cola in 12 hours. Given that the woman also had Type 2 diabetes, they prescribed diet cola. However, the woman apparently balked at this plan, saying she didn't like carbonated beverages, so they scaled back to 1,500 ml, which is about four cans.

Even with the lower dose, it was enough. The next day, the woman "reported a sudden tugging sensation in her abdomen, followed by a prompt decrease in her nausea and abdominal discomfort." Taking another look with an endoscope, the doctors confirmed that the bezoar was gone.

As to how it formed in the first place, the doctors tied it to her use of semaglutide. As a GLP-1 weight-loss drug, one of its effects is slowing down stomach emptying. That in turn can create conditions for a bezoar to form.

In the end, the woman made a full recovery from her symptoms and was back to a regular diet upon discharge from the hospital. She stopped using the semaglutide.
