Infant vomiting and diarrhea is a gastrointestinal problem, which may be caused by indigestion or viral infection. The child’s symptoms can be controlled: if the diarrhea is diluted, the child’s gastrointestinal tract can be adjusted with oral medications such as spleen-awakening and child-raising granules, montelukast, and mametha. Once the child vomits, remember to fast within 1-2 hours after vomiting, do not eat anything, then try not to eat milk, fruit and other supplementary food, you can take oral gruel, rice flour and other non-stimulating gastrointestinal food for comprehensive adjustment. When there is no obvious effect after controlling the diet and oral medication, the child’s stool should be taken to the hospital within one hour for examination to see what causes it, whether it is a virus, bacteria or other causes, and then further adjust the medication according to the results of the stool test.
