Diarrhea is when your child has three or more very loose bowel movements in 1 day. For many children, diarrhea is mild and will pass within a few days. For others, it may last longer. It can make your child feel weak and dehydrated. It can also lead to unhealthy weight loss.

A stomach or intestinal illness is a common cause of diarrhea. It can also be a side effect of medical treatments, such as antibiotics and some cancer treatments. Many other medicines can also cause diarrhea.
