The cause of children’s fever and refusal to eat is mainly due to various infectious factors that cause fever, and after fever, children’s digestive tract secretion of enzymes is relatively low, which will cause a temporary reduction in digestive function. This is the self-protective reaction of the body, and when the fever subsides, the situation of children not eating well will naturally improve. Interventions can also be made to provide significant relief, such as giving children more liquid food, such as thin rice and noodles, and eating more vegetables and fruits to get enough vitamins and trace elements, as well as giving children appetizing and appetizing medications, such as Baohe Pills.
