Children with gastroenteritis are recommended to focus on light, easy-to-digest foods, such as millet porridge and noodles. In the diet should eat more fine and soft, easy to digest food, such as millet porridge, fine hanging noodles, egg custard, lean meat porridge, etc., which is conducive to reducing the burden on the stomach and intestines. Cooking should be light, avoid eating raw and cold, greasy, spicy and other stimulating food. Drink more water to ensure adequate water intake. In normal times, we should pay attention to dietary hygiene, wash hands diligently, and do not eat corrupt and spoiled food. Appropriate physical exercise is conducive to promoting digestion and strengthening one’s resistance. Children’s gastroenteritis should consult the doctor in time, and follow the doctor’s instructions to standardize the diagnosis and treatment.
