Babies can recover from vomiting and diarrhea in about 3 days at the earliest, but in severe cases, it may take up to 1 week or even more than 1 week, depending on the severity of the condition and the triggering factors. If the vomiting and diarrhea is caused by indigestion, it is mainly due to gastrointestinal dysfunction caused by eating irritating food or unclean diet, and the symptoms are mild and can be recovered in about 3 days after active treatment. If the vomiting and diarrhea is caused by bacterial or viral infection, the symptoms are generally more serious and may be accompanied by fever, which requires timely symptomatic treatment and can generally recover in about 7-10 days. In severe cases, chills and convulsions may occur, requiring prompt medical attention, and the specific recovery time varies from person to person. During the period of vomiting and diarrhea, parents are advised to take better care of the baby, and to eat a light and easily digestible diet with balanced nutrition, mainly liquid or semi-liquid food as much as possible.
