There are many causes of pediatric gastroenteritis, including bacterial or viral infections, improper feeding, etc. Gastroenteritis can also occur secondary to a number of diseases, such as bronchopneumonia and otitis media; changes in climate, imperfect functioning of the baby’s digestive system, and poor regulation of the intestinal tract can also lead to gastroenteritis symptoms. The treatment of gastroenteritis is mainly directed at the cause of the disease. If the gastroenteritis is considered to be caused by viral or non-bacterial infection, antibiotics are generally not needed; if the gastroenteritis is considered to be caused by bacterial infection, antibacterial drugs are empirically selected for the pathogen, and then adjusted according to the results of stool culture and drug sensitivity tests. At the same time, intestinal probiotics can be given to help restore the ecological balance of the normal flora of the gastrointestinal tract, intestinal mucosal protectors adsorb pathogens and toxins, maintain the absorption and secretion function of intestinal cells, and enhance the barrier function of the gastrointestinal tract. If the baby’s gastroenteritis is caused by unreasonable feeding, you can give some drugs to help digestion, such as pediatric chemotherapy pills, hawthorn pills, etc. In addition, the diet needs to be light, a small number of meals. If it is secondary gastroenteritis, actively treat the original disease, and can be given at the same time to compress the umbilical cord, oral probiotics and other treatment. If the gastroenteritis is caused by cold, pay attention to keeping your baby warm, and if necessary, give intestinal probiotics to help improve the digestive function of the gastrointestinal tract.
