PICA and its treatment

PICA is a complex disorder characterized by persistent ingestion of non-nutritive substances, such as dirt, clay, chalk, or paint, among others, for a period of at least one month. While this behavior is relatively common in infants and toddlers during their exploratory phase, it becomes a matter of concern when it persists beyond developmentally appropriate stages.Best Pediatrician in Noida suggested that  PICA can pose serious health risks, including poisoning, intestinal blockages, and nutritional deficiencies, making it imperative to understand its causes, symptoms, and treatment options.

Causes of PICA in Children:

  1. Nutritional Deficiencies: Some researchers believe that PICA may be a result of nutritional deficiencies, particularly iron or zinc deficiency, leading to cravings for non-food items.
  2. Developmental Disorders: Children with developmental disorders such as autism spectrum disorder (ASD) or intellectual disabilities may exhibit PICA as a form of sensory exploration or self-stimulation.
  3. Environmental Factors: Exposure to environments where non-food items are readily available or culturally accepted may increase the likelihood of PICA.

Identifying PICA in children requires careful observation of their behavior. Common symptoms include:

  1. Ingestion of Non-Food Items: Children consistently eating items such as dirt, clay, chalk, paper, or hair that are not considered edible.
  2. Hiding or Hoarding Behavior: Children may hide or hoard non-food items, making it challenging for caregivers to detect the behavior.
