Symptoms of gastroenteritis in children include abdominal pain, diarrhea, and fever. Treatment is usually given with anti-infection and other drugs. 1. Symptoms: If a child has gastroenteritis, the stimulation of inflammation will lead to spasm of the gastrointestinal tract, causing abdominal pain and diarrhea. Some children may also have fever, chills, fatigue and other symptoms. 2. Treatment: children with gastroenteritis must be brought to the hospital as soon as possible, under the guidance of the doctor to give the appropriate anti-infection (such as cephalosporin antibiotics, etc.), antidiarrheal (montelukast), antipyretic (acetaminophen, etc.) and other ways of treatment. If a child has gastroenteritis, it is recommended that parents and friends must take their children to the hospital as soon as possible to avoid delays.
