A 14-Year-Old Girl Suffered Stomach Pain for Months—What Doctors Found
It is known as a trichobezoar.
Merck Manual Professional Edition
What exactly is a trichobezoar?
A trichobezoar is a tightly packed collection of hair that accumulates within the stomach.
Human hair contains keratin, a strong structural protein that the digestive system cannot efficiently break down.
When someone swallows small amounts of hair, the material may sometimes pass through the gastrointestinal tract without causing an obvious problem.
However, repeated ingestion can allow strands to become tangled and trapped inside the stomach.
Over time, additional strands may attach to the existing material.
Food particles and mucus can become mixed into the growing mass, producing a dense collection that may occupy an increasingly large portion of the stomach.
Unlike ordinary food, which is processed and moved onward through the intestines, accumulated hair can resist digestion and remain in place.
The resulting mass may gradually interfere with the stomach’s ability to function normally.
For some patients, this process develops without immediately producing dramatic symptoms.
In others, nausea, abdominal discomfort, a reduced appetite, or a feeling of fullness may appear.
The mass can also contribute to complications if it becomes large enough to obstruct the normal movement of food.
The Cleveland Clinic identifies abdominal pain and constipation among possible symptoms associated with trichobezoars and explains that large accumulations may interfere with digestion.

Why can a hair mass become so large?
The stomach is designed to mix food with digestive juices and gradually move its contents into the small intestine.
Its muscular walls repeatedly contract to break down food and propel it onward.
But hair behaves differently from most dietary substances.
It does not dissolve readily in stomach acid, and its long, flexible strands can become entangled.
As more hair collects, the strands may form a dense structure that resists the normal movements of the stomach.
The shape of the mass can sometimes reflect the space in which it developed.
In reported medical cases, surgeons have removed trichobezoars that occupied substantial portions of the stomach.
Some masses have extended beyond the stomach into the small intestine.
This is one reason a rare condition involving swallowed hair can eventually require invasive medical treatment.
However, the size, appearance, and composition of any mass cannot be reliably established from an isolated online photograph.
An unusual object shown in a viral image could represent different materials, and photographs may be separated from their original clinical context.
The diagnosis must come from medical evidence, not visual resemblance alone.
The rare condition called Rapunzel syndrome
One of the most unusual complications associated with trichobezoars is known as Rapunzel syndrome.
The name comes from the fairy-tale character Rapunzel, famous for her exceptionally long hair.
In this medical condition, a large hair mass forms within the stomach and extends through the stomach’s outlet into the intestine.
The resulting structure can resemble a long tail of tangled material.
Rapunzel syndrome is rare, but it is well documented in medical literature.
Its symptoms may include abdominal pain, nausea, vomiting, reduced appetite, and difficulties related to obstruction.
A published pediatric surgical case series described seven patients with trichobezoars ranging in age from 5 to 23 years. Five had extensions beyond the stomach’s outlet, and all seven underwent surgery.
These findings come from a small, selected group of patients and should not be interpreted as estimates of how frequently the condition occurs in the general population.

The dramatic appearance of such masses explains why photographs sometimes attract public attention.
Yet the medical significance goes beyond their unusual appearance.
A large mass may disrupt normal digestion, irritate tissues, prevent adequate food intake, or create an obstruction.
If left untreated in a severe case, complications can become dangerous.
How swallowing hair can be connected to behavior
One sensitive aspect of trichobezoars involves the circumstances in which hair may be swallowed.
Some individuals experience trichophagia, a condition involving recurring urges to eat hair.
It can occur alongside trichotillomania, a disorder characterized by repeated hair pulling.
These behaviors are not simply matters of someone choosing to do something unusual.
They may be associated with difficult-to-control urges, emotional distress, or other mental health concerns.
Not everyone who pulls their hair swallows it, and not everyone who swallows hair develops a trichobezoar.
Likewise, discovering a trichobezoar does not justify making unsupported assumptions about a patient’s personality, family circumstances, or psychological history.
Medical professionals approach these issues by understanding the individual’s symptoms and behavior rather than relying on judgment or blame.
A teenager who experiences urges to pull or swallow hair may hide the behavior because of embarrassment or fear of criticism.
That secrecy can make it difficult for parents or doctors to identify a possible connection with digestive symptoms.
Supportive conversation is therefore essential.
When hair-eating behavior is suspected, clinicians may recommend a combination of medical evaluation and mental health treatment.
Cognitive behavioral approaches and other therapies can help patients understand triggers, recognize urges, and develop alternative responses.

Not every abdominal mass is made of hair
Although trichobezoars receive attention because of their appearance, they represent only one category of bezoars.
Phytobezoars, for example, consist primarily of difficult-to-digest plant material such as fibers, seeds, and fruit skins.
Other bezoars may form from certain medications or different ingested substances.
Factors such as delayed stomach emptying, prior digestive surgery, and other medical conditions can increase the likelihood of certain bezoars forming.
These distinctions matter because treatment varies with the type of material involved.
Some plant-based bezoars may respond to carefully supervised medical treatment or endoscopic removal.
Hair-based masses are generally more resistant to attempts to dissolve them and may require mechanical removal, particularly when large.
Families should never attempt to treat a suspected bezoar with homemade solutions, excessive laxatives, or internet remedies.
A blockage or significant mass requires proper diagnosis, and an inappropriate treatment could delay necessary care.
The difference between a striking photograph and a medical diagnosis
The original story’s image may create an immediate impression that doctors discovered a large, tangled object.
But compelling visual evidence is not the same as a confirmed clinical record.
To establish what happened to a particular patient, readers would need information such as a documented diagnosis, hospital or publication details, and an account of the procedure.
Without these, it is impossible to determine whether the material shown was definitely a trichobezoar, whether the girl had Rapunzel syndrome, or whether the photographed specimen even belongs to the same case.
The appropriate conclusion is therefore measured.
The image raises a legitimate medical possibility, but it cannot independently prove the explanation.
What makes the topic valuable is that the underlying medical conditions are real, recognized, and potentially serious.
Understanding those conditions can help turn a sensational headline into useful health knowledge.
