Children with autism (ASD) tend to have gastrointestinal problems such as abdominal pain, constipation, and diarrhea when compared to their peers.
Many children with ASD eat only a few foods (selective feeding), eat fewer fruits, vegetables, and whole grains. For this reason, children with ASDs may have a low nutrient diet and may have weight-related health problems that can extend into adulthood. Adults with ASD are at increased risk for obesity, high blood pressure (hypertension), and diabetes.
It is often difficult to know how to help a child with ASD and gastrointestinal problems. Deficits in communication with people with ASD often make it difficult to determine if their diet is the cause of gastrointestinal symptoms or if the symptoms are the result of an undiagnosed medical problem. Also, making changes to their diet can be very difficult when a child has become accustomed to selective feeding.
Every child with Autism must be provided with adequate consumption of nutrients in order to have a healthy life.
