Enteritis in children usually takes about a week to return to normal. However, if the infection is severe, or if the child is in poor health, the recovery time may be longer, about two weeks, or even about a month in more severe cases. Since children’s digestive function is relatively weak and their intestinal flora is not yet completely stable, they are prone to flora imbalance. Children are usually more active and some of them are not hygienic, which can easily cause bacterial infections and lead to digestive tract dysfunction and enteritis, causing abdominal pain, diarrhea, vomiting and other symptoms, and in severe cases, even dehydration. At this point, the duration of the disease varies depending on the cause and severity of the enteritis. If the disease is mild and is simply indigestion, the child’s diet should be adjusted and medication should be given under the guidance of a physician, and the child should return to normal in about a week. If it is caused by a viral infection, such as rotavirus or norovirus infection, it usually returns to normal in about 1 week after standard treatment. If the child’s own resistance is poor, or has caused more serious complications, usually need to be hospitalized, then the recovery time will be relatively longer, may take about 2-4 weeks. Children must be hygienic in general, pay attention to washing hands before meals and after defecation, and for children who are weak, try to reduce the number of visits to public places. In addition, they should also pay attention to drinking more boiled water, and actively engage in physical exercise and participate in more outdoor sports. During the period of illness, children should pay attention to a light and easily digestible diet, and can drink millet porridge and other foods in moderation in order to facilitate recovery from the disease.
