Vomiting and diarrhea in babies can have two main types of digestive symptoms, infectious and non-infectious. Non-infectious diarrhea, which mainly includes indigestion and food accumulation, is usually caused by improper feeding, sudden change in the type of food or allergies; the other cause is vomiting and diarrhea caused by sudden change in weather, cold abdomen or overheated weather, and reduced secretion of digestive juices in babies. Infectious diarrhea includes diarrhea caused by infections of various viruses, bacteria, fungi, parasites and other microorganisms. What should I do if my baby has vomiting and diarrhea? First, you should determine the cause of vomiting and diarrhea, find out the cause according to the food your baby eats and weather changes, and then prescribe the right medicine. If it is a poor diet, you can give your baby some probiotics to improve the digestive function of the intestines and promote absorption. For diarrhea caused by weather changes, you should pay more attention to keep your child warm and give him/her more hot water to solve the symptoms of diarrhea well. If the infection is caused by bacteria or viruses, this is the time to go to the children’s hospital for a comprehensive examination and follow the medical advice for medication. Pay attention to the prevention of dehydration. When a child has watery diarrhea, the stool appears watery and egg-like, and this condition is particularly likely to cause dehydration in children. Therefore, as soon as the child begins to have diarrhea, he or she should be given enough fluids by mouth and continue to feed the child, especially infant breastfeeding, to prevent dehydration.
