Infants’ loose stools and watery stools are generally different in character and represent different degrees of severity. 1. Different traits: loose stools are mainly softer, sometimes unshaped, and contain slightly more water than normal feces. Watery stools are characterized by severely misshapen stools that contain more water, and the number of bowel movements and the volume of stools may increase. 2. Disease severity: Infants usually have loose or watery stools when they have diarrhea. Generally, loose stools indicate that the diarrhea is relatively mild, while watery stools indicate that the diarrhea is more severe, and there are also signs of dehydration, such as sunken eye sockets and fontanels. Parents should take their children to the doctor in time to complete the routine blood and stool tests, and then treat them under the guidance of the doctor, and if they are dehydrated, they need to replenish fluids and fight infections in time.
