When a baby has green, loose stools during a fever, in most cases, indigestion has occurred. Once a child has indigestion, he or she is prone to green stools. However, it is important to rule out gastroenteritis as a cause of diarrhea and fever, and it is necessary to check stool and blood tests. If there is an abnormality in the stool routine or blood count, such as elevated white blood cells, it indicates a bacterial infection causing gastroenteritis and fever. In this case, antibiotic treatment is needed, such as pediatric cefixime pellets for babies. If there are no elevated white blood cells and the stool routine and blood count are not abnormal, it is often a fever that causes loose stools. The child’s digestive function will be weakened and the secretion of digestive enzymes will be reduced when he has a fever, so it is easy for indigestion to occur, so it is easy to have a fever accompanied by green, thin stools. This symptom can be changed by giving the child less food and then improving the fever. If the body temperature is higher than 38.5 degrees, you also need to use antipyretic medication, such as ibuprofen suspension.
