Movement of food and drink mixed with gastric secretions through the pyloric sphincter from the stomach into the duodenum. Nutrients (including water) are not absorbed in the stomach; therefore, the benefits of drinking fluids to maintain water balance are obtained only after gastric emptying. Gastric emptying is delayed by fat, intense exercise, and by drinking strong carbohydrate solutions. These inhibitory effects can be compensated for by maintaining a relatively large fluid volume in the stomach.
