Understanding Pica

Pica is an eating disorder that causes people to compulsively eat items not designated for eating. A person with pica might eat relatively harmless items such as ice cubes or may potentially eat dangerous things like dried paint flakes that can result in poisoning. An underlying cause of pica can be a nutritional deficiency or developmental disability, which makes people crave nonfood things. Pica can develop in any person, but it is most common in children, pregnant people, and individuals with intellectual disabilities. It can also develop as a coping mechanism. Although pica is usually temporary, it can have potentially serious consequences.^{[1]XTrustworthy SourcePubMed CentralJournal archive from the U.S. National Institutes of HealthGo to source} You can recognize pica by identifying physical symptoms and observing emotional signs.

Watch eating patterns. A person with pica usually maintains a regular diet of food along with eating non-food items. Pica is present when a person eats non-food items consistently for at least a month. If you suspect that you or another person has pica, keep a mental note or journal of eating habits. This can help identify patterns in consumption that may indicate pica. Some common items a person with pica eats include:^{[2]XTrustworthy SourceNational Eating Disorders AssociationNonprofit organization dedicated to supporting individuals and communities affected by eating disordersGo to source}

Consider prior medical conditions. If you suspect you may have pica, think about prior visits to your doctor or medical conditions you’ve had. A person with pica may be more susceptible to certain conditions than others who don’t consume non-nutritive food items. You may have pica if you eat non-food items and have had one of the following health issues:^{[5]XResearch source}
- Lead poisoning or complications thereof
- Infections from parasites from animals, especially dogs and cats
- Round worm infections
- Intestinal ulcerations or perforations
- Iron or zinc deficiency syndromes
- GI-tract complications
Many small children eat non-food items. If you suspect your child or another person for whom you care has pica, consider checking diapers or in the toilet. You may be able to discern non-food items such as glass, stones, hair, matches, or coffee grounds. Recognize that it may be difficult to difficult to find objects that dissolve in the stomach such as ice, ashes, or soap.^{[6]XResearch source}

Detect red flags for pica. Like other eating disorders, pica can present with not only physical symptoms, but also behavioral or emotional ones. You may notice certain behaviors that can indicate pica, especially when they’re in conjunction with physical symptoms. These include:
- Skipping meals
- Making excuses for not eating
- Withdrawing from normal social activities
- Leaving during meals to use the bathroom
- Expressing disgust, shame, or guilt about eating habits
- Eating in secret
2
Acknowledge negative feelings. Individuals with eating disorders often have negative feelings associated with their condition. Acknowledging that you or another person have these types of feelings can help you recognize pica. Negative feelings individuals with pica may have include:^{[7]XTrustworthy SourceNational Institute of Mental HealthInformational website from U.S. government focused on the understanding and treatment of mental illness.Go to source}
- Confusion
- Anger
- Resentment
- Protective of your habit
- Fear

Put the behavior in context. In some cultures, pica may be a part of everyday life. For example, certain religions and ethnic groups eat clay as a way to treat intestinal issues.^{[8]XTrustworthy SourcePubMed CentralJournal archive from the U.S. National Institutes of HealthGo to source} However, if eating nonfood items is not a part of your culture or is an inappropriate for the person’s age or developmental stage, it may indicate pica.^{[9]XResearch source}
- Be aware that pica is common in individuals with intellectual disabilities, autism, other developmental disabilities, or differences in the brain. If a person with any of these conditions is showing signs of pica, talk to them about what they’ve been eating. You may get the answer simply by asking. Seek medical attention to help you deal with potential pica in a person with developmental disabilities.

Seek medical attention. If your child consumed a harmful substance, seek medical care immediately. If you or another person are at risk for pica and suspect or recognize that you have the disorder, it’s important to see your doctor as soon as possible. Your healthcare provider can check for anemia or other nutritional deficiencies as well as screen for lead poisoning and parasites. Children 2 years old or younger who live in locations where at least one third of the houses were built before 1950 are especially vulnerable and therefore should be screened for lead. Getting medical treatment for pica can help prevent serious further medical conditions.^{[14]XTrustworthy SourceFamilyDoctor.orgFamily-focused medical advice site run by the American Academy of Family DoctorsGo to source}
