Do you ever get the urge to eat things that aren't food? It happens more than you'd think. Things like dirt, paper, chalk, soap, or hair might sound strange, but for people living with pica, these cravings are real. Pica is an eating disorder, not something you're doing wrong, and it can be treated.
Pica occurs across all age groups, though it's more frequently observed in young children, pregnant women, and individuals with developmental disabilities or certain mental health conditions. Like other eating disorders, recovery is possible with therapy and support. Understanding the signs, risks, and available help is the first step to healing.
What is Pica Disorder?
According to the National Association of Anorexia Nervosa and Associated Disorders (ANAD), pica is an eating disorder where individuals compulsively crave and consume non-food items, including things like clay, soil, or paper.
It's common for children to put non-food items in their mouths. However, when this habit goes beyond developmental norms and becomes persistent or poses health risks, a pica disorder diagnosis may be made.
What are the Signs and Symptoms of Pica?
The primary behavioral sign of pica, as per the National Eating Disorder Association (NEDA), is repeatedly eating things that aren't food for at least a month. The substances eaten can vary with age and what's available. Eating these substances goes against an individual’s cultural norms and isn't appropriate for their current age level (developmental stage).
Consuming non-food items can cause a range of physical problems. Digestive issues like stomach pain, constipation, nausea, bloating, and diarrhea are common. Beyond these symptoms, certain items carry specific risks: paint chips can result in lead poisoning, and hair or fibrous materials can block your digestive tract.
What Causes Pica Disorder and What are the Risk Factors?
Like other disorders involving a troubling relationship with food, there's no single cause of pica disorder. However, some causes may include trauma, stress, or anxiety. Based on a study, 'Pica as a manifestation of iron deficiency' published by PubMed, iron deficiency is a potential cause of the pica disorder. Certain medical or mental health conditions could also cause pica.
While pica can happen to anyone, it's more common in children and people diagnosed with autism spectrum disorder, schizophrenia, or intellectual disabilities. Risk factors can increase with pregnancy. Extreme stress or malnutrition may also increase the risk of developing pica disorder.
How is Pica Diagnosed?
Diagnosing pica doesn't involve lab tests. Instead, your healthcare professional will review your medical history, ask about your eating habits, check for physical symptoms, and conduct a psychological evaluation.
Overview of how pica disorder is diagnosed
Healthcare professionals use specific criteria to diagnose pica disorder. These include:
- Duration: The behavior has continued for at least one month.
- Age appropriateness: It goes beyond normal childhood exploration, like toddlers mouthing objects.
- Cultural context: The behavior isn't part of accepted cultural or religious practices.
- Severity: The behavior is serious enough to require professional treatment.
- Associated conditions: Pica often occurs alongside other conditions such as intellectual disabilities, autism spectrum disorder, schizophrenia, or during pregnancy.
What tests help diagnose pica?
While there's no specific test for pica itself, healthcare professionals use various tests to assess related health issues. Blood tests can check for nutritional deficiencies, while X-rays or ultrasounds look for blockages in the digestive tract.
If you've been eating paint chips, toxicology screenings can detect lead poisoning. Stool tests may be used to check for parasites if you've been consuming dirt or soil.
How is Pica Treated?
Treatment for pica varies based on what's causing it. The first step is often identifying and addressing nutritional deficiencies, which can sometimes resolve the behavior on its own.
Behavioral therapy helps people recognize triggers and develop healthier coping strategies. Healthcare professionals may also recommend environmental changes to limit access to harmful substances and medications to manage any underlying mental health conditions. In some cases, alternative treatments are considered as part of a comprehensive care plan.
Frequently Asked Questions
How do I stop my pica cravings?
You can stop your pica cravings by identifying and addressing the underlying cause of your eating disorder. Start by consulting a medical provider and mental health provider who can evaluate you for nutritional deficiencies, mental health conditions, or other contributing factors. Once the cause is identified, you can seek treatment or therapy to help you overcome your pica cravings.
How do you treat a child with pica?
Treatment for children with pica typically starts by checking for and addressing nutritional deficiencies, followed by behavioral interventions as the main approach. These interventions focus on limiting access to non-food items while teaching children to distinguish between what's safe to eat and what's not. Positive reinforcement encourages healthy eating behaviors, and children are redirected to appropriate objects when they need sensory stimulation.
What are the side effects of the pica treatment?
The side effects of pica treatment should be minimal, though certain interventions may cause issues. For example, nutritional supplements may cause stomach upset or constipation, and if medications are part of your treatment, they can have side effects. Behavioral therapy doesn't have physical side effects, but it can feel uncomfortable to change established patterns.
How long does the pica condition last?
How long pica lasts depends on what's causing it and whether you get treatment. In young children and pregnant women, pica often goes away on its own. It may also resolve quickly once nutritional deficiencies are corrected. When pica is linked to mental health conditions or developmental disabilities, recovery typically takes longer and may require ongoing support.
