By We Level Up | Author Kourtney Johnson, RD, LD | Editorial Policy | Research Policy
If you’ve ever had a strong urge to eat something that’s not food, like dirt, clay, or ice you may have experienced pica. This is an eating disorder that affects people of all ages. Pica is characterized by a strong craving for non-food substances that lasts for at least one month.
While the exact cause of pica is unknown, it’s thought to be linked to nutrient deficiencies, mental health conditions, and developmental disorders. Pica can lead to serious health problems if it’s not treated, such as digestive issues, infections, and even poisoning from toxic substances.
If you or someone you know is experiencing symptoms of pica, it’s important to get help from a healthcare professional. They can work with you to identify the underlying causes and develop a treatment plan that addresses your specific needs. With proper care and support, it’s possible to overcome this disorder.

Prevalence and Demographics
Pica affects people from all walks of life, but some groups are at higher risk. Let’s explore who is most likely to develop this eating disorder.
Who is affected by Pica?
Pica can impact people of any age, gender, or ethnicity. But, it’s more common in certain populations, such as pregnant women, children, and those with developmental disabilities. People with mental health conditions like obsessive-compulsive disorder (OCD) or schizophrenia may also be at increased risk for developing pica.
Common age groups and risk factors
Kids under two years old shouldn’t be diagnosed with pica, because it’s normal for them to put non-food items in their mouths. Iron-deficiency anemia, malnutrition and pregnancy are the top three causes of this disorder. People with intellectual disabilities, autism, or brain injuries have a greater likelihood of experiencing pica as well. Other risk factors include poverty, lack of parental supervision, and cultural practices that encourage eating non-food substances.
Common Non-Food Items Ingested
Pica is characterized by consuming non-food substances that offer no nutritional value. The types of items ingested vary widely.
Examples of substances consumed
People with pica may eat:
- Paper
- Soap
- Cloth
- Hair
- Chalk
- Pebbles
- Clay
- Ice
Some people might focus on one substance, while others consume several different items.
Geographic and cultural variations
Pica occurs around the world but is more common in certain regions and cultures. In some parts of Africa, pregnant women eat clay to reduce nausea. This is called geophagy, and it’s also seen in the rural southern United States.
Eating kaolin is also common in parts of Latin America, Asia and the Middle East.
Cultural beliefs and traditions can also influence pica behaviors. Some cultures view eating non-food items as medicinal or spiritually significant. But, these practices can still pose health risks.
Causes of Pica
The exact cause of pica is not fully understood. However, several factors may contribute to the development of this eating disorder.
Psychological factors
Psychological factors can play a large role in the development of pica. Autism spectrum disorder and schizophrenia are also associated with its development. Eating non-food items may provide temporary relief or comfort.
Nutritional deficiencies
Nutritional deficiencies, particularly iron and zinc, are linked to pica. Low levels of these essential nutrients can cause unusual cravings. Anemia, caused by iron deficiency, is common in people with pica. Consuming non-food items may be a way to try to compensate for the deficient nutrients. But, this behavior can worsen nutrient absorption and lead to further deficiencies.
Developmental disorders and Pica
Pica is more common among people with developmental disorders like autism and intellectual disabilities. These conditions can affect judgment, impulse control, and sensory processing. People with developmental disorders might find certain textures or flavors of non-food items appealing. They might also have difficulty understanding the risks of consuming these substances. Proper supervision and behavioral interventions are critical to prevent someone from eating non-food items.
Symptoms of Pica
Pica can form through various behavioral signs and physical effects. If you suspect that you or a loved one may have pica, look out for these telltale symptoms.
Behavioral signs
People with pica often crave and consume non-food substances persistently. They might prefer items like dirt, clay, or ice. Unusual cravings can lead to secretive or shameful behaviors. Pay attention to sudden changes in eating habits or missing household items. Pica can also coexist with other mental health conditions, causing mood swings or anxiety.
Physical effects
Consuming non-food items can lead to serious health consequences. Digestive issues like constipation, bloating, and abdominal pain are common. Pica may cause intestinal blockages or tears, which could require medical intervention. Ingesting toxic substances can result in poisoning, organ damage, or even death. Dental problems, like worn tooth enamel, can develop from chewing on hard objects. Nutritional deficiencies might also develop as pica interferes with proper nutrient absorption.
Diagnosis of Pica
If you or a loved one shows signs of pica, get medical attention for a proper diagnosis. A healthcare professional will conduct a thorough evaluation to determine if you have it or not.
Evaluation process
During the evaluation, your healthcare provider will ask about your eating habits and cravings. They’ll review your medical history and do a physical exam. Blood tests may be ordered to check for nutrient deficiencies or toxins. In some cases, imaging tests like X-rays or ultrasounds are used to check for blockages or damage in the digestive tract. The evaluation process helps identify the underlying causes of pica and guides treatment decisions.
Treatment Options for Pica
Treatment plans could include behavioral management, medication, and addressing underlying causes.
Behavioral Management Strategies
Behavioral management can play a role in treatment. This helps patients unlearn negative behaviors while learning positive ones.
Medication Possibilities
While there’s no specific medication for pica, nutrition supplements should be used if the patient has a deficiency. There are anecdotal reports about using antipsychotic medications, although they can cause constipation and other side effects.
Complications and Side Effects
Pica can lead to various health complications and side effects. If left untreated, it may cause serious harm to your body.
Potential health risks
Consuming certain non-food items can expose you to numerous health risks.
- Ingesting clay can lead to constipation, low levels of potassium in the blood, and nutrition deficiencies. Lead poisoning can also occur.
- Eating ice can cause iron deficiency, especially during pregnancy. Tooth decay and sensitivity might also occur.
- Consuming starch sources like cornstarch or uncooked rice and pasta is connected to iron deficiency. Blood sugar can also be impacted because of the carbohydrate content.
Long-term effects of Pica
Pica can seriously impact your health if it lasts long-term. Potential effects include:
- Bowel obstructions
- Bezoars (blockages in the digestive tract made of non-food materials)
- Heavy metal toxicity
Working with healthcare professionals to manage pica is crucial so you can manage long-term complications.
Self-Care and Management Strategies
Coping with pica can be challenging, but there are strategies that can help. It’s important to remember that you’re not alone in this journey.
Coping Mechanisms
Finding healthy ways to cope with pica urges is critical. Parents whose child has pica can help prevent episodes of consuming non-food items. Using child-proof locks or putting undesired items out of their reach can help.
Psychologists and other mental health professionals can also help manage pica.
Importance of Support Networks
Surrounding yourself with a strong support network can also make pica management easier. This may include:
- Family members and friends who understand and support your journey
- Healthcare professionals who can provide guidance and treatment
- Support groups or online communities for people with pica
- Mental health professionals who can help you cope with underlying issues
Don’t hesitate to reach out for help when you need it. Having a supportive network can make a significant difference in your recovery process.
Preventive Measures
Currently, there isn’t a way to prevent pica. However, because nutrient intake can play a role in various cravings, meeting your nutrition needs may help.
Strategies to reduce risk
If you have any nutritional deficiencies, your healthcare provider may recommend supplements. Keep potential pica substances out of reach, and use safe alternatives for oral stimulation, such as chewing gum or crunchy foods. Work closely with healthcare providers to monitor symptoms and adjust treatment plans as needed.
Outlook for Individuals with Pica
With proper treatment and support, people with pica can overcome their cravings and achieve a healthy diet. The road to recovery may take time, but a positive outcome is possible with dedication and the right resources.
Recovery Outcomes
Pica can last for many months before resolving on its own, especially in kids. Sometimes a robust treatment plan is needed that includes behavioral therapy, coping mechanisms, nutrition counseling and mental health care. Recovery from pica is achievable with a comprehensive treatment plan tailored to your specific needs. Many people who stick to their treatment plan and have a strong support system can overcome pica and maintain a healthy lifestyle. While setbacks may occur, don’t get discouraged—recovery is a journey, and each step forward counts.
Importance of Ongoing Support
Ongoing support is critical for long-term success in managing pica. Surround yourself with a network of family, friends, and healthcare professionals who understand your challenges and can provide encouragement. Attend regular follow-up appointments with your healthcare provider to monitor your progress and adjust treatment as needed. Consider joining a support group for people with pica or similar conditions to share experiences and coping strategies. Remember, you’re not alone in this journey. Having a strong support system can help you stay motivated, accountable, and on track with your recovery goals. Don’t hesitate to reach out for help when needed—your support network is there to cheer you on every step of the way.
