Preschoolers who are picky eaters might be oversensitive to food which can contribute to difficult toileting behaviors, reports a new study. The findings of the study are published in the Journal of Pediatrics.
These children are often picky eaters who might be overly sensitive to food textures, tastes, or odors. They also might have an exaggerated response to noises, bright lights, or other sensory stimuli.
"Our study is revolutionary, revealing that chronic constipation in young children accompanies heightened sensory sensitivity," says senior author Mark Fishbein, MD, a pediatric gastroenterologist at Ann & Robert H. Lurie Children's Hospital of Chicago and Associate Professor of Pediatrics at Northwestern University Feinberg School of Medicine.
In the study, Dr. Fishbein and colleagues assessed the differences in sensory processing patterns between 66 children, 3-5 years of age, with chronic constipation and a matched group of 66 controls. They also examined how the children's sensory profiles correlate to atypical toileting behaviors. They determined that children with chronic constipation showed increased responses to sensory stimuli and increased avoidance behaviors. Heightened oral sensory processing (sensitivity to food textures, tastes or odors) emerged as the most significant factor in predicting the child's tendency to behaviors such as withholding stool or overall bathroom avoidance.
"On the surface, the association between oral processing and constipation may not seem intuitive," says Dr. Fishbein. "However, increased sensory sensitivity can create discomfort and lead to avoidance, and we see that response in both food refusal and the toileting behaviors of children with chronic constipation. Both feeding problems and constipation may develop as a result of sensory processing difficulties."
Recognition of the association between chronic constipation and sensory sensitivity could transform clinical practice.
"Our study offers an expanded tool kit to clinicians who care for children with chronic constipation," says Dr. Fishbein.
"Comprehensive care of these children should include consideration of sensory issues and possible referral to occupational therapy."
