Infants with enteritis usually have frequent and prolonged diarrhea that requires some medication. Diarrhea in babies with enteritis is usually caused by infection and non-infection, and there are also differences in the severity of the condition. In mild cases, it is not necessary to take too much medication, but to pay attention to the baby’s diet and daily care to ensure the amount of intake. If the infection is viral or bacterial, the baby should be given anti-infective treatment. In addition, gastrointestinal mucosa protectors such as montelukast and probiotics should be given to help stop diarrhea. If the baby has obvious dehydration and other serious symptoms, he/she should be sent to the doctor for infusion treatment. If the baby is already dehydrated or has other serious symptoms, the baby should be taken to the doctor for infusion treatment. Diet should also be provided with a list of easily digestible foods, such as drinking some boiled millet porridge can help stop diarrhea and relieve the condition. Babies with enteritis and diarrhea can start with diet and regulation in mild cases, and in serious cases, they need to take medication or send them to the doctor for treatment.
