Patient's question:

Every time the child cries hard, they vomit food. In the morning when they wake up and start eating, they also make a gagging sound, as if they are feeling nauseous. Why is this happening? How should it be prevented and treated?
Medical History: Two years

Doctor's answer:

Hello, it's a pleasure to explain this to you. Checking a child's mouth for any issues is usually normal. When they cry, they swallow a lot of air, which increases pressure in their stomach, causing them to vomit food. Many adults also experience this. If there are no underlying conditions, changing the way the child eats to make mealtime enjoyable, and avoiding running or jumping after meals. Pay attention to their diet, avoiding cold, raw, or irritating foods. If necessary, seek further medical examination and treatment at the hospital.
