Trichophagia: Causes, Symptoms, Complications, Diagnosis, and Treatment

Trichophagia is a rare but potentially serious psychological and medical condition in which an individual compulsively eats hair. The term originates from the Greek words tricho (hair) and phagia (eating). While it is most commonly associated with trichotillomania—a disorder characterized by repetitive hair pulling—not everyone with trichotillomania develops trichophagia.

Over time, ingested hair can accumulate in the gastrointestinal tract, leading to significant digestive complications. Early recognition and appropriate management are crucial to prevent severe health outcomes.

What Is Trichophagia?

Trichophagia is classified as an impulse control and compulsive behavior disorder. It typically occurs alongside psychiatric conditions such as:

• Trichotillomania

• Obsessive-compulsive disorder (OCD)

• Anxiety disorders

• Depression

In many cases, individuals may eat hair subconsciously, especially during periods of stress, boredom, or emotional distress. Because hair is indigestible, it can accumulate in the stomach or intestines, forming a trichobezoar—a compact mass of hair.

Relationship Between Trichophagia and Trichotillomania

Trichotillomania involves repetitive hair pulling from the scalp, eyebrows, eyelashes, or other body areas. Trichophagia may develop when the pulled hair is:

• Chewed

• Swallowed whole

• Ingested repeatedly over time

Not all individuals with trichotillomania consume hair, but studies suggest that 5–20% of affected individuals may develop trichophagia. Among them, a smaller percentage go on to develop gastrointestinal complications.

Causes and Risk Factors

Trichophagia does not have a single cause. Instead, it results from a combination of psychological, emotional, and environmental factors.

Psychological Factors

• Anxiety and chronic stress

• Obsessive-compulsive tendencies

• Poor impulse control

• Emotional trauma

Behavioral and Emotional Triggers

• Coping mechanism for negative emotions

• Habit formation during childhood or adolescence

• Sensory gratification

Demographic Risk Factors

• More common in children and adolescents

• Higher prevalence in females

• Often underreported due to embarrassment

Signs and Symptoms of Trichophagia

Symptoms can be divided into behavioral and physical manifestations. Many individuals hide the behavior, making diagnosis challenging.

Behavioral Symptoms

• Repeated hair pulling and eating

• Playing with hair near the mouth

• Chewing hair ends

• Avoidance of social situations

Gastrointestinal Symptoms

As hair accumulates in the digestive tract, symptoms may include:

• Abdominal pain or swelling

• Feeling full after eating small portions

• Nausea and vomiting

• Loss of appetite

• Constipation or bowel obstruction

• Halitosis (bad breath)

• Unexplained weight loss

Severe Complications

If untreated, trichophagia can lead to:

• Trichobezoar formation

• Gastric or intestinal obstruction

• Ulceration or bleeding

• Perforation of the stomach or intestines

• Peritonitis (life-threatening inflammation of the abdominal lining)

A rare but serious condition known as Rapunzel syndrome occurs when a trichobezoar extends from the stomach into the intestines.

Diagnosis of Trichophagia

Diagnosis often requires a multidisciplinary approach, involving both mental health professionals and medical specialists.

Clinical Evaluation

• Detailed behavioral history

• Assessment of psychiatric symptoms

• Family observations (especially in children)

Imaging and Diagnostic Tests

To identify gastrointestinal complications, doctors may recommend:

• Abdominal ultrasound

• CT scan of the abdomen

• Upper gastrointestinal endoscopy

• Blood tests to assess nutritional deficiencies or anemia

Early diagnosis significantly reduces the risk of surgical intervention.

Treatment and Management

Treatment focuses on both the behavioral disorder and its medical consequences.

Psychological Treatment

Psychotherapy is the cornerstone of trichophagia management.

• Cognitive Behavioral Therapy (CBT)

• Habit Reversal Training (HRT)

• Stress management and coping strategies

• Family counseling (for children and adolescents)

Medical and Surgical Treatment

If hair accumulation has caused complications:

• Endoscopic removal for small trichobezoars

• Surgical removal for large or obstructive masses

• Treatment of nutritional deficiencies

Medications

In selected cases, medications may help manage underlying psychiatric conditions:

• Selective serotonin reuptake inhibitors (SSRIs)

• Anti-anxiety medications

• Mood stabilizers (when indicated)

Medication is typically used alongside therapy, not as a standalone treatment.

Prevention and Long-Term Outlook

With early intervention, the prognosis for trichophagia is generally good. Preventive strategies include:

• Early identification of hair-pulling behaviors

• Stress reduction techniques

• Ongoing psychological support

• Regular follow-up for relapse prevention

Parents and caregivers play a crucial role in recognizing early signs and encouraging professional help without judgment.

When to See a Doctor

Medical attention should be sought if an individual experiences:

• Persistent abdominal pain or bloating

• Recurrent vomiting

• Sudden weight loss

• Known hair-eating behavior with digestive symptoms

Prompt evaluation can prevent serious and life-threatening complications.

Frequently Asked Questions (FAQs)

1. Is trichophagia a mental illness?

Yes. Trichophagia is considered a compulsive behavior disorder and is often associated with underlying mental health conditions such as trichotillomania or anxiety disorders.

2. Can trichophagia be cured?

While there is no single “cure,” trichophagia can be effectively managed with behavioral therapy, psychological support, and treatment of complications.

3. Is trichophagia dangerous?

It can be. Long-term hair ingestion may lead to trichobezoars, intestinal obstruction, and serious infections if left untreated.

4. Who is most affected by trichophagia?

It is more commonly seen in children, adolescents, and young adults, particularly females, though it can affect people of any age or gender.

5. How is trichophagia different from pica?

Pica involves eating non-food substances such as clay or paper, whereas trichophagia specifically involves eating hair.

6. Can children outgrow trichophagia?

Some mild cases may resolve with age, but persistent behavior usually requires psychological intervention to prevent complications.

7. How is a trichobezoar detected?

Imaging studies such as ultrasound, CT scans, or endoscopy are commonly used to detect hair masses in the gastrointestinal tract.

8. Can trichophagia recur after treatment?

Yes, relapse is possible, especially if underlying psychological triggers are not addressed. Long-term follow-up is important.

Trichophagia is more than a habit—it is a complex condition that bridges mental health and gastrointestinal medicine. Early recognition, compassionate care, and a multidisciplinary treatment approach can prevent serious complications and significantly improve quality of life. Awareness among patients, families, and healthcare providers is essential for timely diagnosis and effective management.
