Gastrointestinal (GI) issues are very common in individuals with autism, particularly those who have difficulty with communication and sensory processing. GI issues can range from mild stomach aches to severe and chronic symptoms, such as irritable bowel syndrome (IBS) and inflammatory bowel disease (IBD). These GI issues can cause feeding disorders in children with autism. Treatment for GI issues typically involves dietary modifications, medication, and other lifestyle changes that can be learned in feeding therapy. It is important to consult with a medical professional to develop an effective plan to address concerns.
