Patient's question:

Usually, he has a bowel movement once every morning, but tonight he suddenly had diarrhea, most of which was watery and！（He vomited a few times yesterday and went to the hospital for treatment. The doctor said it was caused by a cold and gave him intravenous fluids for anti-inflammatory treatment）Doctor's answer:
Hello, infant diarrhea, also known as indigestion, is a digestive disorder caused by dysfunction of the spleen and stomach. This condition occurs in all four seasons, with higher prevalence in summer and autumn. It is most common in infants under the age of two. After onset, it can easily deplete qi and yin, and severe cases may develop dangerous complications. There are two types of persistent diarrhea: infectious diarrhea, typically caused by bacteria and viruses. For example, rotavirus transmitted through the respiratory tract can enter the intestines and cause diarrhea. The other type is non-infectious diarrhea, usually triggered by excessively cold or hot food, or indigestion. Since children's gastrointestinal tracts are not yet fully developed and they secrete fewer digestive enzymes than adults, they are more prone to indigestion, which can lead to diarrhea.
