Patient's question:
How long after dinner should a 9-year-old child wait before engaging in activities? Is it based on their stomach emptying time? It's better to wait until their stomach is empty before doing activities like jumping and bouncing, which are good for their stomach. But what is their stomach emptying time?Doctor's answer:
Enhancing factors: a. Gastric food volume; b. Gastrin.Inhibitory factors: a. Gastrointestinal irradiation; b. Enterogastrone: secretin, gastrin-releasing peptide, cholecystokinin, etc. Factors in the small intestine play a negative feedback regulatory role.
The specific process of gastric emptying: The impact of food on the gastric wall is the driving force for gastric emptying. When the pyloric sphincter opens, gastric activity increases. When the intragastric pressure exceeds the duodenal pressure, the gastric contents can enter the duodenum. However, the gastric contents that enter the duodenum stimulate various receptors in the intestinal wall, reflexively causing a weakening of gastric activity and a slowdown in emptying, thereby inhibiting gastric activity and emptying.
