Abstract:
Beyond the hallmark social and sensory difficulties in autism spectrum disorder (ASD), the comorbid gastrointestinal (GI) conditions and their potential link to the severity of core symptoms require clinical attention. Although evidence indicates that autistic children face a greater risk of GI disorders and require more intensive nutritional management compared to neurotypical peers, standard guidelines for managing GI symptoms in this population remain lacking. This review seeks to pinpoint critical considerations for the implementation of nutrition-based strategies aimed at addressing GI dysfunction in individuals with ASD. By emphasizing clinical translation and the mechanistic understanding of these strategies, it highlights the importance of restoring gut homeostasis as a pathway to improve functional independence and overall well-being. Furthermore, we outline priorities for clinical research aimed at developing evidence-based nutritional recommendations to support GI health in autistic individuals, emphasizing personalized and population-specific needs.
