Indigestion in babies does not usually cause fever. Indigestion is a non-infectious disease, which is characterized by bloating, vomiting, reduced appetite, and prolonged bowel cycles or increased exhaustion. Fever is an infectious disease, such as viral infection, bacterial infection, mycoplasma infection, etc. If there are symptoms of infection in the digestive system, it can be complicated by indigestion and fever. Therefore, it is important to clarify the cause when diagnosing. In the case of bacterial enteritis or viral enteritis, fever symptoms can occur and can also occur along with symptoms of indigestion. It is a mistake to assume that indigestion is accompanied by fever.
