What is the Difference Between Peristalsis and Antiperistalsis?
🆚 Go to Comparative Table 🆚The main difference between peristalsis and antiperistalsis lies in the direction of food movements within the gastrointestinal (GI) tract:
- Peristalsis: This is the normal movement of food through the GI tract. It involves the involuntary constriction and relaxation of muscles, creating wave-like movements that push the food bolus downwards from the mouth, through the esophagus, stomach, and intestine.
- Antiperistalsis: Also known as retroperistalsis, this is the backward or upward movement of food within the GI tract, opposite to the normal direction. It occurs from the stomach to the mouth and is not considered a normal movement.
Both peristalsis and antiperistalsis are wave-like movements of smooth muscles in the GI tract, but they serve different functions and move in opposite directions.

Comparative Table: Peristalsis vs Antiperistalsis
Here is a table comparing the differences between peristalsis and antiperistalsis:
Feature | Peristalsis | Antiperistalsis |
---|---|---|
Direction of Movement | Downward | Upward or backward |
Occurrence | Mouth to esophagus to stomach to intestine | Stomach to mouth |
Type of Contraction | Normal | Abnormal or reverse |
Movement of Food Bolus | Propagates food from mouth to stomach | Pushes food from stomach to mouth |
Smooth Muscle Involvement | Wave-like movements of smooth muscles in the GI tract | Reverse wave-like movements of smooth muscles in the GI tract |
Peristalsis is the normal, downward movement of food through the gastrointestinal tract, while antiperistalsis is the abnormal, upward or backward movement of food from the stomach to the mouth.
