The GI Motility Program at Cedars-Sinai uses an interdisciplinary team approach to ensure that each patient receives individualized care from experts in the fields of gastroenterology and GI motility. Cedars-Sinai is known around the world for its leading-edge research, attention to quality patient care and expertise.

Physicians in the Cedars-Sinai GI Motility Program are renowned for their expertise and frequently sought out by other physicians for consultations. The sophisticated motility tests available through the program are reviewed by Cedars-Sinai motility specialists, who report the results back to the patient's referring physician, usually within in 24 hours.

Our expert team consists of physicians who are specialists in gastrointestinal medicine and GI motility, technicians and specially trained nurses.


Many of the physicians who have medical staff privileges to practice medicine at
Cedars-Sinai Medical Center are independent physicians, and not employees or agents of the hospital. These independent physicians bill separately for their services. You should contact your physician to determine their status and billing practices.
