Does peristalsis reverse direction

Peristalsis typically does not reverse direction; it is a coordinated, wave-like contraction of smooth muscle that propels food through the digestive tract in one direction—from the esophagus to the stomach, and then through the intestines. However, in certain conditions, such as with severe gastrointestinal obstruction or certain neurological disorders, abnormal contractions can occur, leading to backward movement or regurgitation. But under normal circumstances, peristalsis is unidirectional.
