When accumulating food, it is usually appropriate to eat less watermelon, and should be avoided if gastrointestinal function is poor. In the process of growth and development of infants or children, the occurrence of food accumulation is more common. If there is no discomfort symptoms from eating watermelon before, you can eat less watermelon appropriately, which usually will not increase the burden on the gastrointestinal tract. If there is a change in gastrointestinal function after eating, abdominal pain, diarrhea and other conditions, should be avoided to prevent aggravating the burden on the gastrointestinal tract. In the state of food accumulation, the child’s gastrointestinal function is weaker, and extra attention should be paid to the diet, with light, easy-to-digest food, such as porridge, noodles, etc., and less or no greasy, cold and indigestible food. If the patient’s symptoms of food retention are serious or persist without improvement, it is recommended to go to a regular hospital in a timely manner, after clarifying the cause of the disease, under the guidance of the doctor for targeted treatment.
