How to Get Rid of a Bezoar Naturally

The most evidence-backed way to dissolve a bezoar without surgery is surprisingly simple: drinking Coca-Cola or a similar carbonated beverage. This approach works best on phytobezoars, the most common type, which form from indigestible plant fibers. But the phrase “get rid of naturally” deserves some honest framing, because bezoars are not a minor inconvenience you can handle entirely at home. They can cause ulcers, bleeding, and bowel obstruction, and some types will never dissolve no matter what you drink or eat. Knowing what kind of bezoar you’re dealing with, and when to stop trying home remedies, matters as much as the remedy itself.

What a Bezoar Actually Is

A bezoar is a mass of indigestible material that accumulates in the gastrointestinal tract, usually the stomach. They fall into four main categories depending on what they’re made of: phytobezoars (plant fibers), trichobezoars (hair), pharmacobezoars (medications), and lactobezoars (milk protein, mostly seen in infants).¹ Each type behaves differently, responds to different treatments, and carries different risks. Phytobezoars are by far the most common in adults, and they’re also the type most likely to respond to non-surgical treatment. When people ask about getting rid of a bezoar “naturally,” phytobezoars are where most of the evidence lives.

Gastric bezoars, meaning those sitting in the stomach, often cause ulcers and bleeding. When a bezoar migrates into the small intestine, the risk shifts toward bowel obstruction.¹ This distinction matters because where the bezoar is located affects which approaches are even possible.

Who Gets Bezoars and Why

Bezoar formation is complex and multifactorial, and people with certain risk factors or existing medical conditions are significantly more likely to develop one.² The biggest risk factors include previous stomach surgery (especially ulcer surgery or bariatric procedures), gastroparesis (where the stomach empties too slowly), poor dental health leading to inadequate chewing, and diets heavy in fibrous or indigestible plant material.

People who can’t chew their food properly, whether because of missing teeth or poorly fitting dentures, are at elevated risk. So are people who swallow seeds whole, eat seed shells, or consume large amounts of high-fiber foods without drinking enough water.³ Persimmons deserve a special mention: they contain high levels of tannin that reacts with stomach acid to form a sticky, cement-like mass. Patients who have had gastric surgery have been specifically warned about persimmon ingestion because of the unusually high rate of bezoar formation that follows.⁴

The Coca-Cola Approach

If you’ve read anything about dissolving bezoars, you’ve probably encountered the Coca-Cola method. It sounds like folklore, but it’s backed by a reasonable body of clinical evidence, and it’s the most-studied non-invasive approach for phytobezoars. A prospective randomized trial comparing Coca-Cola consumption to other interventions found that its dissolution effect is real and measurable.⁵

The mechanism isn’t fully understood, but several factors seem to contribute. Coca-Cola has a pH of about 1.9, which is actually more acidic than dilute hydrochloric acid. That acidity remains stable even hours after the can is opened. The carbonic acid and phosphoric acid in the drink are thought to help digest plant fibers. The carbon dioxide bubbles and the sodium bicarbonate provide a mucolytic effect, helping to break down the sticky matrix holding the bezoar together. And drinking a large volume of the liquid enhances gut motility, helping move broken-down fragments along.⁵

In clinical practice, doctors typically have patients drink Coca-Cola over a period of days or weeks, sometimes combined with other treatments. But the success rate isn’t 100%. In some case reports, two weeks of cola dissolution therapy at home was completely ineffective against hard, large bezoars, and the patient ultimately needed endoscopic fragmentation.⁶ The takeaway: Coca-Cola can work, especially on smaller or softer phytobezoars, but large or very firm masses often resist it.

Enzymatic Agents and Other Dissolution Methods

Beyond carbonated beverages, clinicians have historically used several enzymatic and chemical agents to try to dissolve phytobezoars. These include cellulase (an enzyme that breaks down plant cellulose), papain (from papaya), and acetylcysteine (a mucolytic drug normally used for respiratory conditions). Some approaches combine Diet Coke with cellulase, attacking the plant fibers from multiple angles.⁷

These methods sit in a gray area between “natural” and medical. Cellulase supplements are available over the counter and are sometimes marketed for digestive support, but using them specifically to dissolve a bezoar is really a clinical decision. Papain, which was once used more commonly, has fallen somewhat out of favor due to concerns about mucosal irritation. If you’re interested in enzymatic dissolution, this is a conversation to have with a gastroenterologist, not something to experiment with alone.

When Coca-Cola Partially Works and That Becomes a Problem

Here’s something that catches many people off guard: partial dissolution of a bezoar can actually cause new problems. When a large gastric bezoar softens and breaks into fragments, those fragments can migrate out of the stomach and get lodged in the small intestine, where the passage is much narrower. One documented case involved a patient whose gastric bezoar, after dissolution therapy, migrated and caused both acute pancreatitis and small bowel obstruction.⁸

This is an important reason why “trying Coca-Cola at home for a few weeks and hoping for the best” has real limits. If you have a confirmed bezoar, especially a large one, dissolution therapy ideally happens under medical supervision so that any complications from fragment migration can be caught early. Your doctor might combine Coca-Cola therapy with imaging follow-up or pair it with endoscopic monitoring.

Why Trichobezoars Don’t Dissolve

Trichobezoars, or hairballs, are a fundamentally different problem. Human hair is made of keratin, a protein that resists stomach acid and virtually every dissolution agent available. There is no known chemical or dietary method that reliably dissolves a trichobezoar once it forms. Surgery is almost always required.⁹

Trichobezoars form in people who pull out and swallow their own hair, a condition called trichophagia, which is often connected to trichotillomania (compulsive hair pulling). A small minority of people with trichotillomania develop trichophagia, and an even smaller subset develop a true trichobezoar, but when one does form, it can be life-threatening.¹⁰ In extreme cases, the hair mass fills the entire stomach and extends into the small intestine, a presentation sometimes called Rapunzel syndrome.

The real “natural” prevention here is addressing the underlying psychiatric condition. Treatment for trichotillomania typically involves psychotherapy and sometimes medication such as selective serotonin reuptake inhibitors.⁹ If you or someone you know has a habit of pulling and swallowing hair, early psychiatric intervention is the most important step, because once a trichobezoar is large enough to cause symptoms, surgery is essentially the only option.¹¹

Pharmacobezoars and Medication Clumps

Pharmacobezoars are masses formed from medications, usually extended-release tablets that stick together in the stomach. An in vitro study found that certain extended-release tablets, including formulations of quetiapine, paracetamol, and verapamil, can form firm clumps stable for more than four hours when they come into contact with simulated gastric fluid. Some of these clumps remained intact for up to 24 hours, with drug release reduced substantially compared to separated tablets.¹²

Pharmacobezoars are particularly relevant in overdose situations, where a patient may have taken many tablets at once. But they also form occasionally in people who take multiple large pills daily. The key difference from phytobezoars is that pharmacobezoars can release unpredictable amounts of drug over time, creating an ongoing toxicity risk. Treatment usually involves whole-bowel irrigation or endoscopic removal. Carbonated beverages aren’t the answer here. If you suspect a medication clump is causing symptoms, this is a hospital visit, not a home remedy situation.

Dietary Changes That Actually Help Prevent Recurrence

Prevention matters because bezoars have a frustrating tendency to come back, especially in people whose underlying risk factors haven’t changed. After a bezoar has been removed or dissolved, the focus shifts to making sure another one doesn’t form. The key recommendations are straightforward but worth spelling out.

First, increase your water intake. Dehydration slows stomach emptying and makes fibrous material more likely to clump together.³ Second, chew your food thoroughly. People with dental problems should address those issues, because large, poorly chewed food particles are one of the most consistent risk factors. Third, be cautious with high-fiber foods, especially persimmons, citrus pith, and fibrous vegetables eaten in very large quantities. This doesn’t mean avoiding fiber entirely; it means not eating excessive amounts, and especially avoiding foods known to be problematic.¹³

For people with gastroparesis, meaning a stomach that empties abnormally slowly, dietary modifications are part of a broader treatment plan that often includes prokinetic agents to help the stomach contract and move food along.¹⁴ If you’ve had bariatric surgery, nutritional counseling that specifically addresses bezoar risk should be part of your post-operative care. The evidence is clear that patients after bariatric surgery need to be told about changing their eating habits, including adequate chewing and drinking, and avoiding overindulgence in high-fiber foods.¹³

Red Flags That Mean You Need a Doctor Now

Trying to dissolve a bezoar at home makes sense only if you know the bezoar is small, you’re being monitored, and you’re not experiencing danger signs. Certain symptoms mean the situation has moved beyond anything Coca-Cola can handle.

Severe abdominal pain, vomiting that won’t stop, an inability to pass gas or have a bowel movement, or signs of shock like rapid heartbeat and dropping blood pressure all suggest a bezoar may have caused an obstruction or perforation. Early intervention is critical to prevent bowel ischemia or perforation, and when conservative treatments fail, surgery becomes necessary.¹⁵ Gastric bezoars can cause hemorrhage and shock, while phytobezoars lodged near the pylorus can lead to gastric necrosis, both of which require surgical intervention.

If you have diabetes and slow gastric emptying, be especially watchful. Elderly diabetic patients are overrepresented in case reports of bezoar-related bowel obstruction, likely because gastroparesis and dietary habits compound each other.

What Happens When Home Remedies Fail

When dissolution therapy doesn’t work, the next step is usually endoscopy. A gastroenterologist can use various tools, including snares, alligator forceps, and even electrohydraulic lithotripsy (essentially a shock wave), to break the bezoar into pieces small enough to pass naturally.¹⁶ Endoscopy is less invasive than surgery and is generally the preferred first-line approach for bezoars that resist chemical dissolution.

For very large bezoars, or when endoscopy fails, surgical removal is the final option. This can often be done laparoscopically.¹⁷ Advances in both endoscopic and surgical techniques have made bezoar treatment considerably safer than it once was, but the progression from least invasive to most invasive is important: try dissolution, then endoscopy, then surgery.¹⁸

The Historical Reputation of Bezoars

Bezoars have a strangely glamorous history that runs counter to their unpleasant clinical reality. For thousands of years, bezoar stones (usually from goats or other ruminants) were believed to be powerful antidotes to poison. They were used across Persian, Arabic, and European medicine as cures for ailments ranging from plague to epilepsy to leprosy.¹⁹ The word “bezoar” itself comes from the Persian “pādzahr,” meaning “protection from poison.” Royal courts paid enormous sums for bezoar stones, and they were often mounted in gold settings.

None of this has any bearing on modern treatment, of course. But it explains why the word sometimes sounds vaguely mystical to people encountering it for the first time, and why some corners of the internet suggest that bezoars have curative properties rather than being a medical condition that needs treatment. They don’t. A human bezoar is a mass of undigested material that needs to come out, one way or another.
