The rate of gastric emptying is influenced by the type and amount of food consumed. In healthy individuals, it typically takes 1-4 hours for the stomach to empty its contents into the duodenum. The rate of emptying can be slower with high-fiber or high-fat meals and faster with liquids. Factors such as gastric motility, the presence of gastric emptying hormones, and the presence of food in the intestine also play a role in this process.
