Children on the autistic spectrum frequently suffer from gastrointestinal complaints such as diarrhoea, constipation, abdominal pain, abdominal distension and flatulence. Far from being 'just part of the condition', worldwide research is confirming parents' reports that many of these children are actually suffering from serious underlying conditions which, if left untreated, are a source of constant pain, which in turn can greatly exacerbate autistic behavioural symptoms. Autism and Gastrointestinal Complaints summarises the symptoms often experienced and offers an accessible explanation of the underlying medical condition, together with practical suggestions as to how to help reduce the child's suffering. The findings of the latest research are presented in an understandable way, with a glossary explaining some of the terms often used by medics in plain language. This book offers a concise guide to all aspects of gastrointestinal complaints in children with autism, and is an ideal resource for parents, teachers and any other family member or caregiver who needs to know how to help an autistic child.
