Pediatric food retention, also known as functional dyspepsia, can be relieved by general treatment and medication. 1. General treatment: avoid eating too fast, maintain regular dietary habits, and avoid spicy, greasy and gas-producing foods. 2. Medication: Gastric stimulating drugs such as mosapride and domperidone can be used to promote gastrointestinal peristalsis; acid-suppressing drugs such as omeprazole and pantoprazole as well as antacid drugs such as magnesium aluminum carbonate can also be used for treatment. In addition, the symptoms of food accumulation can also be alleviated by clockwise massage of the abdomen and chiropractic. Children with food retention are advised to go to the hospital for a doctor’s judgment and treatment plan.
