Infantile enterocolitis is the most common of all infantile diseases. When an infant has enterocolitis, there are many signs and symptoms, which parents should know in detail in order to detect and treat it early. Infants and toddlers with enteritis will have a significant fever, and the baby will be particularly unrefreshed and weak. In addition, there are obvious gastrointestinal symptoms, including loss of appetite, nausea, vomiting, and an increase in the number of stools, from 3 to 10 times a day, or even more. The stool may change in character and may appear as a thin, watery stool. Mild cases do not show edema and systemic toxicity, and most children recover within a few days. However, in addition to nausea, vomiting, and diarrhea, children with severe enterocolitis may show signs of dehydration, coma, and other symptoms of systemic toxicity, which can lead to death in severe cases. When a baby has enteritis, parents should have the ability to distinguish between mild and severe enteritis. In case of severe enteritis, the baby should be sent to the doctor for a routine stool test to confirm whether it is caused by bacteria or viruses, so as to treat the symptoms. If the symptoms of enteritis are mild, the baby should be given a proper diet and have his or her normal needs met. If your baby is normally breastfed, you should continue to breastfeed. Give your baby plenty of water to avoid worsening the condition due to dehydration caused by diarrhea.
