Autism is a complex neuro-developmental disorder that tremendously affects the normal functioning of brain which challenges the child’s development. Autism is characterized by impaired communication (both verbal and nonverbal), impaired interpersonal social interaction and repetitive, restricted and stereotype mannerism of behavior or presence of unusually strong narrow interest. The presentation of these impairments is variable in range and severity and varies with the acquisition of other developmental skills.

According to WHO report, it is estimated that worldwide about 1 in 100 children have autismⁱ. In India according to a report by ET Health World, about 18 million people in India are diagnosed with autism. About 1 to 1.5 percent of children aged 2 to 9 years are diagnosed with ASDⁱⁱ. Autism affects more male than female individuals. Etiology of autism is not yet known, but both genetic and environmental factors appear to play role. Environmental factors that may contribute to the etiology of ASD include pre or postnatal exposure to certain environmental chemicals and drugs, stress, maternal infection and dietary factors. Along with this, alteration in gut microbiota (gut dysbiosis) and other GI disorders are found in autistic children. That is derangement in digestive and metabolic system.
