Hayat Mousa, MD is the director of the Suzi and Scott Lustgarten GI Motility Center at Children’s Hospital of Philadelphia (CHOP). Dr. Mousa holds the Suzi and Scott Lustgarten Endowed Chair for Clinical Care of GI Motility Disorders.
Dr. Mousa joined CHOP September 1, 2020 from her previous role as clinical director of pediatric gastroenterology and the director of the Neurogastroenterology and Motility Center at Rady Children's Hospital-San Diego.
Dr. Mousa is a national leader and world-renowned expert in pediatric gastrointestinal motility disorders. She was trained at Children's Hospital of Pittsburgh, with broad exposure to all gastrointestinal disorders including liver disease, small bowel transplantation and gastrointestinal motility disorders. Subsequently, she joined the GI group at Nationwide Children's Hospital in Columbus, Ohio, where she developed its motility center, served as the medical director for motility for 15 years, and served as the fellowship director of a GME-approved training program in pediatric motility disorders for 10 years.
Dr. Mousa's key interests include swallowing disorders, gastroparesis, gastric electric stimulation, constipation, cecostomy, sacral nerve stimulation, rumination, gastroesophageal reflux, Hirschsprung's disease, gastrointestinal motility diseases and functional disorders. She has special clinical expertise in managing patients in multidisciplinary settings and had an active role in developing both an aerodigestive and a colorectal center in former institutions.
Her research, which is widely published, is focused on chronic intestinal pseudoobstruction, pre- and post-transplantation, gastric accommodation and compliance after fundoplication in comparison to its baseline before the surgery, gastroesophageal reflux and its association with apnea & respiratory symptoms, and gastric pacing with its effect on gastric function and quality of life.
Dr. Mousa is an active member of various professional societies, including the American Neurogastrointestinal Motility Society, Society for Pediatric Research, North American Society for Pediatric Gastroenterology, Hepatology and Nutrition (NASPGHAN), American Gastroenterology Association, and the Association of Gastrointestinal Motility Disorders (AGMD).
Among her honors and awards are the NASPGHAN Motility Prize, Nationwide Children Hospital Career Contribution Award and the NCH IMPACT Business Process Improvement Program Award.

Patient Experience Ratings
About the Patient Experience Rating System
The Patient Experience Rating is an average of all responses to the care provider related questions shown above from our nationally-recognized Press Ganey Patient Satisfaction Survey. Patients that are treated in outpatient or hospital environments may receive different surveys, and the volume of responses will vary by question.
Responses are measured on a scale of 1 to 5 with 5 being the best score.
We are committed to true transparency. However, to ensure the comments are fair and correctly attributed, we review each one before posting to the website. We exclude entire comments that disclose patient's protected health information, are off-topic, or include other confidential or inappropriate content. Comments will appear on provider bios only if providers have a minimum number of comments.
Comments are shared internally for education purposes to ensure that we are doing our very best for the patients and families for whom we are privileged to care.
The comments are submitted by patients and families and reflect their views and opinions. The comments are not endorsed by and do not reflect the views of Children’s Hospital of Philadelphia.
