Infant diarrhea is treated by replacing the fluid in the body. Usually this is done through oral feedings. But, if the infant is extremely dehydrated, it is done intravenously, by pumping fluid into the body through a vein.
Breast-feeding mothers should continue to breast-feed while the infant has diarrhea. Formula-fed infants can be treated best by using one of the commercially available rehydrating solutions, such as Pedialyte or Infalyte. Once the stool frequency decreases, or if the infant's appetite seems to improve, then the infant's usual formula feedings can be resumed.
There are generally few side effects to the above treatments. If medications are needed for the underlying cause of the diarrhea, there may be side effects to the medications. These include further stomach upset or allergic reactions.
A few days of diarrhea generally is not a cause for concern. The exception would be if the infant is not drinking enough fluid to compensate for the liquid lost in the diarrhea. If diarrhea continues despite treatment, the healthcare provider should be notified.
Most cases of diarrhea last three to five days. A healthcare provider should be called immediately if one of the following conditions applies:
Any other new or worsening symptoms should also be reported to the healthcare provider.
