GI Motitility In the Stomach. 1  Two types of movement (motility) occur in the stomach: peristalsis and segmentation (mixing). 2  The contractions occur about every 20 seconds and proceed from the body of the stomach toward the pyloric sphincter. 3  About 20% of the contractions in the stomach are peristaltic waves.
During a process called peristalsis, stomach muscles and the small intestine contract and move contents forward in the gastrointestinal tract. âThese sounds occur both when the stomach is full and when it is empty.â Dr. Shawn Khodadadian, a gastroenterologist in New York City, told FoxNews.com. âAbout two hours after your stomach empties, there is signaling from the brain for the digestive muscles and peristalsis to begin again.
