A 6-year-old child who vomits when he/she eats may be due to his/her underdeveloped stomach function or the child may be born with a gastrointestinal disorder. It may also be due to the child’s usual disorganized daily eating habits, often eating greasy and irritating foods. This condition generally requires first clarification of whether it arises from pathological or physiological causes. If, in addition to such symptoms, the child also suffers from loss of appetite, frequent coughing and vomiting, or occasional fever or fever, the child needs to be examined at a hospital, which may be due to pathologically induced symptoms. It is best for children to eat more light foods, and they can eat more fruits and vegetables that are rich in vitamins and fiber. This can replenish the nutrients needed by the body and also help digestion. And usually drink more hot water and get more sunlight.
