Children with autism below the age of three, experience atleast one gastrointestinal discomfort, compared to a typical child, reveals a study.

At ages 6 to 18 months the parents reported symptoms such as constipation, food intolerance and food allergies and at ages 18 months to 3 years, diarrhea, food allergies and food intolerance were the common complaints.
Children with autism were more than twice as likely to have at least one gastrointestinal symptom during both of these age ranges. Genetics may play a role in both autism and gastrointestinal symptoms, or the two conditions may share another underlying mechanism, suggest researchers.
“Even though GI symptoms are common in early childhood, physicians should be mindful that children with ASD may be experiencing more GI difficulties in the first three years of life than children with typical development or other developmental delays”, concluded the researchers, from Columbia University.
