The most common cause of gastrointestinal colds in children is viral infections. Clinical supportive treatment is usually provided, and the disease is usually self-limiting, so antiviral medications are not routinely used, and supportive treatments such as fever-reducing medications, montelukast, oral rehydration salts, etc. are used. 1. Supportive treatment: Children usually have fever, and when the body temperature is as high as 38.5 degrees, antipyretics such as ibuprofen and acetaminophen can be used as prescribed by the doctor. Montelukast helps the gastrointestinal mucosa to recover from the damage, and also acts as an antidiarrheal agent. When your child has a gastrointestinal cold that shows signs of dehydration, drink plenty of fluids, use oral rehydration salts to replenish fluids, or use intravenous fluids. 1. Antiviral treatment: Antiviral drugs are not routinely used for gastrointestinal colds, but can be used as prescribed by the doctor if there is an immune abnormality in the child or if the viral infection is severe, such as ribavirin. If you suspect that your child is suffering from gastrointestinal flu, parents should take your child to the hospital for examination, make a clear diagnosis and then carry out targeted treatment, and the above drugs should be used under the guidance of the doctor. At the same time, you need to let the child eat a light diet, eat more vegetables and fruits.
