Understanding acute diarrhea

Diarrhea can be acute, persistent, or chronic. With acute diarrhea, which is one of the most common, there are an estimated 179 million cases in the US each year. Many cases are infectious, meaning caused by an infection, while many others are a side effect of medication. Two of the biggest complications to watch out for are dehydration and malabsorption.

What causes it?

Acute diarrhea typically lasts for one to two days and goes away on its own. The most common symptom is passing loose, watery stools multiple times per day. Infectious diarrhea can also cause blood in the stool, fever or chills, dizziness, and vomiting.

Typically, adults in the US get acute diarrhea once per year, while young children have it an average of two times per year. People who visit developing countries are at greater risk from consuming contaminated food or water—hence the common term, traveler’s diarrhea.

In addition to being a common side effect of medicines such as antibiotics and cancer drugs, acute diarrhea is caused by three main infections. These include viral infections, such as the norovirus and rotavirus; bacterial infections, such as from E. coli or clostridioides difficile (c. diff); and less commonly, parasitic infections. 


Treating acute diarrhea by getting to the root cause.

With a variety of potential causes, the right treatment plan for acute diarrhea will vary, too. Your unique diet, mental health, and lifestyle also play a role. That’s why our experts take a continuous care approach, working closely with you to identify the right combination of treatments that provide real, lasting relief. We won’t give up until we get it right, whether that’s on our first try, or our fourth.
