Antiperistalsis

Antiperistalsis

Antiperistalsis is a backward wave that occurs in the digestive tract that moves toward the mouth (i.e., up or away from the direction of normal passage of food) (compare: peristalsis). Previously, it was believed that antiperistalsis caused vomiting in humans. However, studies have shown that in humans antiperistalsis is not related to the process of vomiting.

Previously it was believed that this causes vomiting in humans, but studies have shown that antiperistalsis in humans has nothing to do with this process.

Antiperistalsis is a reverse impulse of peristalsis that can occur in the gastrointestinal tract. This phenomenon manifests itself in the form of reverse movement of food, which can be both physical and psychological. Despite the fact that it was previously believed that antiperistalsis causes vomiting in humans, modern research shows that it has nothing to do with this process.
