The phenomenon of accumulation of food in babies is usually caused by overeating or prolonged eating of food that is not easy to digest. Babies with food retention also show more clinical symptoms, such as abdominal pain, abdominal distension, nausea and vomiting, irritability, loss of appetite, yellowish color, warmth of the hands and feet, decreased frequency of bowel movements, bad breath, mental instability and other symptoms. Babies with food retention will have abdominal pain, loss of appetite, and individually, if there are severe symptoms of food retention, it may cause high fever, crying and restlessness. Of course, for babies with fever, although there may be triggers for food retention, it is also important to be aware of the infection that has occurred, and must not be completely stuck in the understanding of food retention. Other children who have accumulated food may have a loss of appetite, and their stomachs may bulge because the food in their stomachs is not digested, or because they produce too much gas in their intestines. Some children may also experience nausea and vomiting, and there may be a sour odor in the mouth if the food in the stomach is not digested for a long time. Therefore, it is crucial to solve the problem in a timely manner after your baby has accumulated food. First, record and analyze your child’s daily diet to find out the cause of the accumulation of food, and then take your baby to the pediatrician of the hospital for systematic treatment if necessary.
