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 several times yesterday and went to the hospital for treatment. The doctor said it was due to a cold and gave him intravenous fluids for anti-inflammatory treatment）Doctor's answer:
Hello. Diarrhea in children, also known as indigestion, is a digestive disorder caused by dysfunction of the spleen and stomach. This condition can occur in all four seasons, with higher prevalence in summer and autumn. It is most commonly seen in infants and young children under the age of two. After onset, it can easily deplete qi and yin. In severe cases, dangerous complications may arise. There are two main types of persistent diarrhea: infectious diarrhea, which is typically caused by bacteria and viruses, such as rotavirus transmitted through the respiratory tract, which can lead to diarrhea once it enters the intestines. The other type is non-infectious diarrhea, usually caused 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 result in diarrhea.
