Pica may not always resolve on its own, so it’s important to understand the condition and learn about available treatment options.
Pica is a mental health condition characterized by the intense urge to consume nonfood items. While these eating habits often subside without professional intervention, other people with pica will continue to eat dirt, hair, sand, feces or other non-food items for an extended period, which puts their health at risk. In most cases, these individuals require strategies from a treatment team of physicians, nutrition experts and mental health professionals to find relief from their symptoms.
Although various factors contribute to the development of pica, a lack of certain nutrients can trigger the desire to eat non-food materials. This connection explains why some women who are pregnant and people with zinc or iron deficiencies may experience symptoms of pica.
To combat this cause, nutritional experts like physicians, dietitians and nutritionists test individuals with this condition for missing nutrients and other medical problems associated with pica, such as lead poisoning and indigestible masses in the body. Once the professionals establish physical safety, they will encourage diet changes to compensate for any nutrition deficiencies present.
With a balanced diet and adequate vitamins and minerals, pica symptoms tend to diminish quickly. If the person is unable or unwilling to adjust their food intake, the professional may recommend dietary supplements to stabilize and increase nutrients in the body.
Some people with pica will see their symptoms quickly diminish with nutritional coaching, diet change and supplements. Others will require mental health therapy to decrease unwanted urges.
Mental health treatment for children with pica focuses on:
- Educating people with pica and their families about the condition, including possible causes, risks and treatment strategies
- Creating a safe environment for the child where they will not be injured by consuming chemicals or other hazardous materials
- Removing preferred nonfood items from the home
- Increasing the supervision so the person cannot eat the nonfood items and blocking any attempts to do so
- Using distraction to sway the child toward a desirable behavior
- Praising the child for eating healthy food items and discarding nonfood items that they would have previously eaten
The cornerstone to childhood treatment of pica is behavior modification. The primary aim of this therapeutic technique is to reinforce desired behaviors through rewards, like food, verbal praise, money, toys and prizes. Parents may also administer punishments, like timeouts or extra chores, to decrease the frequency of pica behaviors. Studies of pica using these behavior modification principles saw a 96 percent reduction in eating nonfood items within weeks of the treatment beginning.
For adults with pica, many of the same techniques apply. Friends and family can take turns exposing their loved one to items the person would like to eat and reward them for resisting the urge to consume the items.
Currently, there are no medications specifically approved to treat pica, but that does not mean no drug options exist. Researchers and prescribers have begun to find some benefit from medicines.
Medications that enhance a chemical in the brain called dopamine might help improve pica symptoms. Medications like Zyprexa, a drug ordinarily used for schizophrenia, may also reduce the urges and impulses to eat nonfood items.
Additionally, medications used to manage severe behavioral problems in children may prove effective in treating pica as well. As always, it is essential to discuss all medication options with your physician.
Treating Pica and Co-Occurring Disorders
Since pica commonly co-occurs with other mental health disorders, it is valuable to receive a thorough evaluation from a mental health specialist to understand what other conditions may be present and the best ways to manage their symptoms.
Pica frequently co-occurs with mental health conditions like:
- Autism spectrum disorder
- Intellectual disabilities
- Obsessive-compulsive disorder
- Trichotillomania (hair-pulling disorder)
- Excoriation (skin-picking) disorder

When mental health conditions co-occur, the individual and treatment providers must take steps to address all symptoms, rather than only focusing on one symptom or one condition. Without a comprehensive approach to pica and co-occurring disorder treatment, there will be limited progress.
