4 min read

According to the Cleveland Clinic, pica is an eating disorder where a person compulsively eats non-food items, including bricks. A craving for brick is a specific manifestation of this condition, and it can stem from nutritional deficiencies, mental health factors, or other underlying issues. While it may seem unusual, understanding the root cause is the first step toward effective treatment and recovery.

Quick Summary

A craving for brick is a form of pica, an eating disorder linked to nutritional deficits like iron deficiency or underlying mental health conditions. Identifying the cause is crucial for proper management and treatment.

Key Points

Pica and Deficiency: Craving brick is a form of pica, an eating disorder often caused by severe nutritional deficits, such as iron, zinc, and calcium.
Mental Health Links: The compulsion can also be connected to underlying mental health conditions, including autism spectrum disorder, intellectual disabilities, and obsessive-compulsive disorder.
Significant Health Risks: Ingesting brick is dangerous due to risks of intestinal blockage, dental damage, infections from parasites, and poisoning from toxic materials like lead.
Professional Diagnosis: Accurate diagnosis requires a medical consultation and testing to check for nutritional imbalances or other health complications.
Effective Treatment Plan: A comprehensive approach to treatment typically involves addressing any detected nutritional deficiencies and engaging in behavioral or psychological therapy.
Preventive Environment: In cases involving children or those with developmental issues, removing access to the craved item and ensuring proper supervision are critical.
Do Not Self-Treat: Eating the non-food item will not resolve the underlying deficiency and can create additional, severe health problems.

Understanding the Phenomenon of Pica

The medical term for compulsively eating non-food items like bricks, soil, or paint chips is pica. The name is derived from the Latin word for magpie, a bird known for its indiscriminate appetite. While pica is often associated with children and pregnant women, it can affect individuals of any age and may be a symptom of a more serious health concern. The compulsion to eat something with no nutritional value, like brick, is not a simple habit but an indication that an underlying issue needs to be addressed. Ignoring these cravings can lead to significant health complications, including dental damage, digestive issues, and poisoning from ingesting toxic materials.

Nutritional Deficiencies as a Cause

One of the most widely cited reasons for pica is a nutritional deficiency, particularly a lack of iron, zinc, or calcium. A case study in the National Institutes of Health (NIH) journal documented a 7-year-old girl with a three-year history of eating brick pieces. Her blood tests revealed significant deficiencies in iron, zinc, and calcium, leading to a diagnosis of pica. However, the crucial point is that eating the non-food item does not correct the deficiency; in fact, substances in the consumed items can sometimes bind to minerals, making the deficiency worse. The physiological theory suggests that the craving is a misdirected attempt by the body to replenish these low levels, although the non-food substance does not provide the needed nutrient.

Psychological and Mental Health Triggers

Beyond nutritional deficits, several mental and psychological conditions are linked to pica. It is recognized as a mental health condition where individuals compulsively consume non-nutritive items. The urge can sometimes serve as a coping mechanism or an outlet for stress and anxiety. Pica is more prevalent in individuals with certain mental health conditions, including autism spectrum disorder, intellectual disabilities, and schizophrenia. In some cases, trauma, neglect, or obsessive-compulsive tendencies can be contributing factors. A mental healthcare professional can help explore these psychological roots and develop a treatment plan that addresses the behavioral and emotional aspects of the condition.

The Dangers of Ingesting Brick

Ingesting brick is a hazardous act with potential for serious health consequences. Brick can contain harmful substances, including lead-based paint in older structures, which can lead to lead poisoning. The material itself can cause physical damage, from wear and tear on teeth to internal injuries. Key risks include:

Intestinal Blockage: Ingested pieces can accumulate in the digestive tract, causing a dangerous blockage that may require surgery.
Toxic Substances: Older bricks or those treated with certain chemicals can introduce toxic materials into the body.
Infections: Exposure to soil and contaminants associated with brick can increase the risk of parasitic and bacterial infections.
Dental Damage: The hardness of brick can severely wear down or even fracture teeth.

Pica and Brick-Related Risk Factors: A Comparison


Factor	Pica in General	Craving Brick Specifically
Associated Nutrient Deficiencies	Iron, zinc, calcium are common	Strong link to iron deficiency anemia observed in cases.
Typical Populations	Children, pregnant women, and individuals with developmental disabilities	Can occur in all associated pica groups, but some cases are tied to specific geographical or social factors.
Psychological Profile	Often linked to anxiety, stress, or other psychiatric conditions	May be related to sensory-seeking behaviors due to its unique texture and mineral-like quality.
Infection Risk	High, especially with geophagia (dirt eating)	Risk from soil, parasites, and bacteria attached to or within the brick.
Obstruction Risk	Varies depending on item (e.g., hair vs. paper)	High risk due to hardness and irregular shape of fragments.
Toxicity Risk	Can be low (ice) or high (paint chips)	High risk, especially with older bricks that may contain lead paint.

What to Do If You Crave Brick

If you or someone you know experiences a desire to crave brick or other non-food items, it is crucial to seek professional help. The behavior is not a harmless quirk but a symptom that requires medical and sometimes psychological intervention.

Consult a Medical Doctor: The first step is to visit a healthcare provider. A doctor can order blood tests to check for underlying nutritional deficiencies, such as anemia, and rule out any medical complications from potential ingestion, such as lead poisoning.
Get a Nutritional Assessment: A registered dietitian can help evaluate dietary habits and suggest a plan to address any deficiencies. Addressing these deficits, particularly with supplementation if needed, is a key part of recovery.
Seek Psychological Evaluation: Since pica can be tied to mental health disorders like anxiety, OCD, or developmental issues, a referral to a mental health professional is often necessary. Therapies like behavioral modification can be very effective in treating pica.
Implement Environmental Changes: For those with intellectual or developmental disabilities, or for young children, modifying the environment is critical. This involves removing access to the item and increasing supervision to prevent further episodes.

Conclusion

In conclusion, a craving for brick is a manifestation of the eating disorder known as pica, which can have both physical and psychological roots. The underlying cause is frequently a nutritional deficiency, particularly a lack of iron or zinc, but it can also be a symptom of mental health disorders or a coping mechanism for stress. Regardless of the cause, consuming bricks is incredibly dangerous and poses severe risks, including internal blockages, dental damage, and exposure to toxic substances like lead. Seeking professional medical and psychological help is essential for a proper diagnosis and treatment plan. Addressing the core issue, whether through nutritional supplementation, behavioral therapy, or environmental controls, is the safest and most effective way to overcome the urge and prevent serious health complications.
