She arrived at a major US hospital doubled over, terrified by waves of pain and nausea that nothing seemed to calm.
Within a day, using a treatment that sounded more like a prank than a prescription, her condition flipped from alarming to stable – and Coca-Cola, of all things, played a starring role.
A mysterious stomach pain that kept getting worse
The patient, a 63-year-old woman, checked into Brigham and Women’s Hospital in Boston with intense nausea, repeated vomiting and a persistent burning pain in her upper abdomen. The discomfort wrapped around her right side and shot into her back.
These symptoms had not appeared overnight. For months, she had been dealing with non-bloody vomiting and a spreading burning sensation after meals, but it had recently escalated to the point where she could no longer tolerate it.
Her medical history was already heavy: type 2 diabetes, early-stage chronic kidney disease and long-standing acid reflux. At first glance, doctors could have blamed her symptoms on those long-term conditions.
The pattern of pain and vomiting did not quite match her usual diagnoses, so the team decided to dig deeper.
Blood tests, imaging exams and a CT scan of her abdomen followed. The images made it clear that something unusual was going on inside her stomach.
A sticky mass hiding in the stomach
The scans revealed two major findings. First, her bile ducts were dilated, a sign that something might be disturbing the flow of digestive juices. Second, her stomach was visibly enlarged and appeared to be filled with a semi-solid mass rather than normal liquid contents.
An endoscopy – a camera inserted through the mouth into the digestive tract – gave the real answer. Doctors found a lumpy, glue-like clump occupying a significant part of her stomach. They identified it as a gastric bezoar, a compact mass made of indigestible material.
Bezoars can form from hair, medications, milk curds or, most often, from undigested plant fibres such as fruit and vegetable skins. In this case, the mass was consistent with a so-called “phytobezoar”, made of plant material.

Gastric bezoars are rare, showing up in fewer than 0.5% of people undergoing certain upper digestive endoscopies.
When they grow large, bezoars can block the passage of food from the stomach into the intestine and trigger pain, nausea, vomiting and weight loss. They can also be confused with tumours on imaging scans, adding to the anxiety.
Standard options: scalpels and scopes
Once a bezoar is diagnosed, doctors usually have three main strategies:
- Surgical removal – opening the stomach to physically take out the mass.
- Endoscopic fragmentation – using tools through an endoscope to break the bezoar into pieces.
- Chemical dissolution – attempting to dissolve the clump with specific solutions.
Surgery can be effective but carries the usual risks: anaesthesia complications, infection and longer recovery. Endoscopy is less invasive, but complex cases can still be technically difficult and time-consuming.
For this patient, the team wanted a gentler option if possible. That is where an unlikely candidate entered the discussion: Coca-Cola.
The Coca-Cola prescription that changed everything
In recent years, gastroenterologists have built up a modest but growing body of evidence showing that Coca-Cola can help dissolve certain gastric bezoars, particularly those made of plant fibres.
Coca-Cola’s mix of carbonic acid, phosphoric acid and dissolved CO₂ seems capable of softening and breaking apart tough fibrous clumps.
Studies published in specialised gastroenterology journals suggest that the beverage’s acidity and fizz can weaken the structure of phytobezoars, making them easier to dissolve or fragment with an endoscope.
For the Boston patient, doctors decided to try a Coca-Cola-based therapy before scheduling more invasive procedures. The original plan was bold: 3,000 millilitres (about 8.5 cans) of Coca-Cola over 12 hours, administered orally.
The woman was far from enthusiastic. She told staff she disliked fizzy drinks and felt the volume was simply too much. After discussion, the team agreed to cut the dose in half, to 1,500 millilitres over the same period.
Twenty-four hours, and a radical change
Within less than a day of starting the Coca-Cola regime, her condition shifted. The violent nausea eased. The feeling of pressure and heaviness in her upper abdomen faded. She no longer felt on the brink of vomiting with every movement.
A follow-up endoscopy confirmed the clinical improvement. The bezoar that had occupied her stomach had completely disappeared. No surgery. No complex fragmentation procedure. Just a carefully monitored, short-term Coca-Cola treatment.
After 1,500 millilitres of Coca-Cola, doctors reported that the gastric bezoar had fully vanished and her symptoms dramatically improved.
She was able to resume a light diet and was discharged, with instructions for close follow-up and medication review.
A surprising suspect: a trendy diabetes and weight-loss drug
The medical team did not stop at the immediate fix. They wanted to know why this bezoar had formed in the first place. The patient’s records revealed that she was taking semaglutide, a GLP‑1–based drug used for type 2 diabetes and widely prescribed off-label for weight loss.
GLP‑1 drugs slow down how quickly the stomach empties, which can help people feel full for longer and eat less. That effect is useful for blood sugar control and weight reduction, but it can also change how food moves and breaks down in the stomach.
In certain patients, that slowdown may increase the risk of bezoar formation, especially when combined with high-fibre meals or existing digestive issues.
Doctors suspect that semaglutide’s impact on stomach emptying played a key role in the build-up of the gastric mass.
Reports of stomach paralysis and severe digestive side effects linked to GLP‑1 drugs have raised questions in recent years. This case adds another possible complication to watch for, particularly in older patients with multiple conditions.
Can you treat stomach problems with fizzy drinks at home?
The idea that a soft drink could resolve a serious medical issue is tempting, and social media thrives on such stories. Many people already reach for cola when they feel bloated or queasy, believing it will “settle” the stomach.
Doctors stress that this approach does not work for most digestive complaints. For mild bloating, carbonated drinks might slightly stimulate digestion, but they can also increase gas and discomfort in others.
Using Coca-Cola as a treatment belongs strictly in a medical setting for a few reasons:
- The volume used is large and must be monitored.
- Underlying conditions like diabetes or kidney disease can be affected by sudden sugar and fluid intake.
- Not all bezoars respond to cola, and some need urgent surgery instead.
Self-medicating with litres of soda for stomach pain could delay a proper diagnosis of ulcers, gallstones, pancreatitis or even cancer.
What exactly is a gastric bezoar?
For anyone unfamiliar with the term, a few key points help clarify the picture:
| Type of bezoar | Main components | Typical patients |
|---|---|---|
| Phytobezoar | Fruit and vegetable fibres, skins, seeds | People with slow stomach emptying, high-fibre diets |
| Trichobezoar | Hair | Often young women with hair-pulling and hair-swallowing behaviours |
| Pharmacobezoar | Medication residues | Patients on certain slow-dissolving or resin-based drugs |
Symptoms can be vague: early fullness, nausea, vomiting, abdominal pain, bad breath or unexplained weight loss. Because they mimic many other conditions, bezoars are usually only found once doctors use imaging or endoscopy.
Hidden risks behind “miracle” weight-loss shots
The Boston case also highlights a broader issue. As GLP‑1 drugs spread far beyond diabetes care and into cosmetic weight-loss use, doctors are seeing more people with unexpected digestive problems: severe constipation, vomiting, and delayed gastric emptying.
For a patient with older age, diabetes, past stomach surgery or long-standing reflux, the risk of food stagnating in the stomach may rise further when these medicines are added.
A practical conversation between patient and clinician can reduce those risks. That includes discussing:
- Existing digestive symptoms before starting a GLP‑1 drug.
- Meal composition, especially very fibrous or bulky foods.
- Warning signs such as persistent vomiting, black stools or sharp new pains.
Stopping or adjusting the medication, changing diet, or scheduling an endoscopy early can prevent situations where a bezoar silently grows until it triggers an emergency.
What this unusual case means for everyday readers
Stories like this one spread fast because they mix two familiar elements: a household brand and a dramatic hospital rescue. Behind the headline, though, sits a detailed piece of clinical reasoning and a reminder that even common products can have precise medical uses when handled correctly.
For most people, the key takeaway is not to start drinking cola for every stomach ache, but to pay attention to persistent, unexplained digestive changes, especially if you take multiple medications or have recently started a new drug such as semaglutide.
In rare, carefully selected cases, doctors may reach for something as unassuming as Coca-Cola to solve a complex problem. The real lesson lies in the careful diagnosis and monitoring that made that choice safe – not in the myth that a fizzy drink is a cure-all for gut trouble.
