I understand the general idea of food traveling from the mouth to the stomach via the esophagus. It stays there for some time. Then it moves to the duodenum and stays for some time. Then the small intestine, then the large intestine. But does anyone know what happens when someone eats a snack before the previous meal has left the stomach? Let’s assume food stays in the stomach for 4 hours. This person eats lunch, then 2 hours later eats a snack. Will the stomach now hold the lunch for an additional 2 hours because of the snack? submitted by /u/hafuf22 [link] [comments]
