Neurogastroenterology and Motility Program

The GI tract contains several organs, including the esophagus, stomach, intestines, rectum and anus. These organs are made up of muscles and nerves that work together to digest food and remove waste (stool) from the body. The movement of food and waste along the GI tract is known as motility. Damage to GI muscles or their associated nerves can lead to a motility disorder. 

Our Neurogastroenterology and Motility Program director is Ricardo Medina-Centeno, MD, a pediatric gastroenterologist who specializes in treating these conditions. He provides a thorough evaluation and advanced testing and treatment, as well as referrals to other providers who can help, including psychologists and physical therapists.

Phoenix Children’s offers a monthly multidisciplinary clinic for children with motility disorders and colorectal conditions (conditions of the colon and rectum that often cause motility issues). It is the only clinic of its kind in Arizona for children who may need surgery to correct a problem in the GI tract. Patients see Dr. Medina-Centeno, a pediatric colorectal surgeon and a nurse specializing in motility and colorectal disorders.
