When to Seek Care for Diarrhea

 Acute diarrhea sends 179 million American adults to the doctor annually. Most of the time, it stems from a temporary viral infection or foodborne illness and resolves on its own within a day or two. However, chronic or severe cases require prompt medical attention.

At Gateway Gastroenterology in Chesterfield, Missouri, our specialists are experts at evaluating and treating persistent bowel changes. Untreated, chronic, or severe diarrhea can lead to serious complications such as dehydration or an electrolyte imbalance.

Red flag symptoms that require immediate care

Diarrhea is defined as having three or more loose or watery stools in a 24-hour period. It’s considered severe when you have more than 10 bowel movements a day, or diarrhea in which fluid losses are significantly greater than oral intake.

The Gateway Gastroenterology team urges you to seek an evaluation if you experience any of the following: 

  • Diarrhea lasting more than two days without improvement
  • Signs of severe dehydration, such as extreme thirst, dry mouth, little to no urination, or dizziness
  • Severe abdominal or rectal pain
  • Stools that appear black or tarry or contain visible blood or pus
  • A fever higher than 102 degrees Fahrenheit

You should also seek medical help if you are at high risk of complications from a severe bout of diarrhea. This includes adults age 65 and older, young children, pregnant women, and those with weakened immune systems. 

Understanding chronic cases

Chronic diarrhea can signal an underlying gastrointestinal condition that requires specialized diagnostic testing. Potential root causes include:

  • Inflammatory bowel diseases like Crohn’s disease or ulcerative colitis
  • Celiac disease or gluten sensitivity
  • Food intolerances, such as lactose intolerance
  • Malabsorption disorders or thyroid imbalances

If you’ve been managing loose stools for weeks, our specialists will work to identify the exact cause to build a targeted treatment plan for lasting relief.

What to expect during your evaluation

We perform a thorough assessment. This begins with a review of your medical history, recent travel, dietary changes, and current medications.

Depending on your symptoms, our team might recommend diagnostic tests such as:

  • Stool tests to check for bacterial, viral, or parasitic infections
  • Blood tests to screen for inflammation, anemia, or celiac disease
  • Breath tests to evaluate food intolerances or bacterial overgrowth
  • Endoscopy or colonoscopy to directly inspect the lining of your digestive tract
