Pediatric oesophagia is a gastrointestinal disorder formed when the baby’s spleen and stomach are not yet well developed, and then too much milk is consumed, damaging the spleen and stomach, and undigested filth accumulates and blocks the intestinal tract. Most cases of paediatric oesophagus occur in infants and young children. The symptoms of paediatric food accumulation are manifested in the following aspects: a. Children with food accumulation will have a poor appetite, not wanting to eat and having a poor appetite. Some children will say that their stomach hurts and tummy rises, and they will find bulging when they press the child’s stomach. 2. Children with food retention do not sleep well, they often turn over and over, and sometimes they clench their teeth. When you put your nose close to the child’s mouth, you will smell the sour gas coming out of the child’s mouth. This is because the food is stored in the stomach and is not digested for a long time, resulting in acidity. Fourth, some children with anorexia are in a bad state of mind, accompanied by feverish hands and feet, nausea and vomiting. If a child is found to be anorexic, parents must not only let the child pay attention to the diet and eat less undigested food, but also let the child eat a light diet, instead of eating less and more meals, and control the amount of food.
