Diarrhea - what to ask your health care provider - adult

Diarrhea is when you have more than 3 very loose, watery, or unformed bowel movements in 1 day. For many, diarrhea is mild and will pass within a few days. For others, it may last longer. It can make you feel weak and dehydrated. It can also lead to unhealthy weight loss.

A stomach or intestinal illness can cause diarrhea. It can be a side effect of treatments, such as antibiotics and some cancer treatments. It may also result from taking some medicines and consuming artificial sweeteners such as those used to sweeten sugar free gum and candies.
