Vomiting in toddlers is considered to be related to acute gastroenteritis, which can be relieved by dietary adjustments and medication. 1. Dietary adjustment: If acute gastroenteritis is triggered by eating cold food or unclean diet, leading to vomiting and diarrhea, the diet should be adjusted to give easy-to-digest, light, less residue liquid diet to reduce the burden on the gastrointestinal tract, and temporary fasting is needed if the vomiting is severe. In addition, children need to drink more water to avoid dehydration. 2. Medication: If the acute gastroenteritis is triggered by bacterial infection, you can follow the doctor’s instructions to take oral amoxicillin, cefixime and other antibiotics, or under the guidance of the doctor to give the child fasting thioglycollate gel to protect the mucous membrane of the gastrointestinal tract, but also take probiotic drugs such as bifidobacterium triplex and other drugs, regulating intestinal flora. If necessary, toddlers can follow the doctor’s instructions to use oral rehydration salts or intravenous rehydration to avoid dehydration or electrolyte disorders. Young children eat bad stomach vomiting need to go to the hospital in time, under the guidance of the doctor’s treatment, not blindly self-medication, in order to avoid delaying the condition, resulting in other damage. All of the above medications should be used under the guidance of a doctor.
