Diarrhea Q & A

What is diarrhea?

Diarrhea is an increase in the frequency of your bowel movements or looseness of your stool. These can occur independently of each other, but they most commonly occur together. If your stool is liquid or watery, this is always considered diarrhea. The looseness of the stool is caused by increased water in the stool during the digestion process.

There are two types of diarrhea: acute and chronic. Acute diarrhea lasts from a few days to maybe a week. Chronic diarrhea usually lasts more than three weeks, but not necessarily continuously. The type of diarrhea you have will help determine the cause, and it will require different diagnostic tests and treatment.

What causes diarrhea?

The most common cause of acute diarrhea is infection, due to a virus, bacteria, or parasite. This happens in the case of food poisoning or infection from contact with contaminated food or water. Acute diarrhea is often accompanied by cramps or nausea. Acute diarrhea can also result from starting a new medication.

Chronic diarrhea is usually the result of a noninfectious condition, such as irritable bowel syndrome (IBS), an inflammatory bowel disease (such as Crohn’s disease or colitis), endocrine conditions (such as overactive thyroid), absorption malfunctions, and cancer. 

How do you treat diarrhea?

Acute diarrhea usually resolves on its own over time. However, Dr. Pullano recommends the “brat” diet: banana, rice, applesauce, and toast. These foods are generally easy to digest during a bout of diarrhea. Patients should avoid dairy products and acidic foods. Dehydration is a common side effect of diarrhea, so be sure to increase your fluid intake.

In the case of chronic diarrhea, Dr. Pullano needs to conduct a full evaluation to determine the cause, and he’ll develop a treatment plan based on the diagnosis.  

You should seek medical attention for your diarrhea if you also have:

  • High fever (temperature greater than 101℉)
  • Severe abdominal pain or tenderness
  • Blood in your stool
  • An illness where dehydration may have serious consequences (such as heart disease or diabetes)
  • Prolonged vomiting that prevents you from drinking fluids
  • Just completed a course of antibiotics
  • Recently returned from developing countries or from camping
  • A chronic intestinal disease such as colitis or Crohn's disease

Diarrhea is common and most people can treat it on their own, but some cases of diarrhea require the professional expertise of an experienced gastroenterologist like Dr. Pullano to diagnose and treat it effectively.
