The physical examination provides additional clues. A clinician may check for abdominal tenderness, swelling, or signs of dehydration. Depending on the symptoms, the doctor may also look for evidence of nutritional deficiencies or other medical problems. However, a physical examination alone may not be enough to identify a bezoar, especially if the mass is located deep within the stomach or if the symptoms are nonspecific.
Imaging tests can play an important role. A CT scan of the abdomen may reveal a mass within the stomach and help doctors assess its size, shape, and relationship to nearby structures. It may also show whether the mass is associated with obstruction or other complications. The appearance of a suspected bezoar on imaging can guide the next steps, but the findings must be interpreted by a qualified clinician alongside the patient's symptoms and examination.
An upper gastrointestinal endoscopy is another important tool. During this procedure, a specialist passes a flexible tube equipped with a camera through the mouth and into the esophagus, stomach, and sometimes the first part of the small intestine. This allows direct visualization of the digestive tract. If a mass is present, the endoscopist can assess its appearance and determine whether an endoscopic approach might be appropriate.
Endoscopy can be particularly useful because it lets the clinician inspect the mass rather than relying only on indirect images. In selected cases, some types of bezoar can be broken up and removed endoscopically. However, a dense hair mass can be difficult to fragment and retrieve safely. If the mass is very large, tightly compacted, or associated with complications, surgery may be a more appropriate option.
Blood tests may be ordered to assess the patient's general condition. Depending on the clinical situation, tests can look for anemia, electrolyte disturbances, dehydration, inflammation, or nutritional deficiencies. These results do not necessarily identify the bezoar itself, but they can show how prolonged symptoms have affected the body and help guide treatment before or after a procedure.
Doctors also need to distinguish a trichobezoar from other causes of an abdominal mass or obstruction. Food material, plant fibers, medication-related concretions, and other conditions may produce different findings. A mass that resembles hair in a photograph cannot be reliably classified without appropriate clinical information. Similarly, the fact that a surgeon removed unusual material does not automatically establish the exact diagnosis, the reason it formed, or the duration of the underlying condition.
A sensitive medical history can be important when hair ingestion is suspected. The clinician may ask whether the patient has a habit of pulling out or swallowing hair, whether this behavior occurs during stress, and whether the person experiences urges that are difficult to control. Such questions should be asked privately and respectfully. Many patients may feel embarrassed or fear being judged, even though the purpose is to understand the problem and prevent recurrence.
It is essential to recognize that hair pulling and hair eating are not the same behavior. Trichotillomania involves recurrent hair pulling that can be difficult to resist. Trichophagia involves eating or swallowing hair. Some people experience both, but not everyone with a trichobezoar has the same behavioral history. A medical team should not make assumptions based on age, gender, appearance, or the presence of a hair mass alone.
Once the diagnosis is established, doctors can discuss the safest treatment plan. The decision depends on the mass's size, the patient's symptoms, whether there is an obstruction, and whether other complications are present. A stable patient with a relatively small mass may be managed differently from someone who cannot tolerate food, has severe pain, or shows signs of intestinal blockage. The goal is to remove the underlying problem safely and protect the digestive tract from further injury.
Patients can help by reporting symptoms accurately and disclosing relevant behaviors or concerns without fear of blame. A clinician's role is to provide care, not to shame the patient. Honest information can be particularly valuable when a condition may recur if its underlying cause remains unaddressed.
The diagnostic journey may feel lengthy when symptoms are vague, but ongoing abdominal pain should not be dismissed simply because its cause is not immediately obvious. If pain persists, worsens, or appears with repeated vomiting, unexplained weight loss, blood in vomit or stool, or an inability to eat and drink normally, medical evaluation is important. Severe pain, a rigid or markedly swollen abdomen, fainting, or signs of significant dehydration require urgent attention.

When a trichobezoar becomes large enough to cause symptoms, treatment focuses on removing the mass and addressing any damage or complications it has caused. The exact approach depends on the mass's size, location, density, and relationship to the surrounding digestive structures. There is no single procedure suitable for every patient, and the decision should be made by a medical team after reviewing the clinical findings.
For some bezoars, endoscopic removal may be possible. During upper gastrointestinal endoscopy, specialized instruments can sometimes break up or extract material through the mouth without making an abdominal incision. This approach may be suitable for selected smaller or less densely packed masses, depending on the clinician's assessment and the equipment available. However, hair is particularly resistant to digestion and can form a tough, intertwined structure that is difficult to fragment.
