Common Causes of Diarrhea and When to See a Doctor

Most people experience diarrhea at some point in their lives, and while it is often brief, it can sometimes be a sign of something serious. At South Island Gastroenterology Associates in Lawrence, NY, Steven Kadish, MD, and Jonathan Zinberg, MD, help patients understand what might be causing their symptoms and when it’s important to seek medical care.

Everyday Causes of Diarrhea

Diarrhea can develop for many reasons, and in many cases, it resolves on its own. Common triggers include viral infections, often referred to as “stomach bugs,” which typically clear up within a few days. Food intolerances, such as difficulty digesting lactose, can also lead to diarrhea after eating certain foods. Some people experience diarrhea after eating too much fatty or greasy food, while others may notice it when traveling due to exposure to unfamiliar bacteria.

Medications are another frequent cause. Antibiotics, for example, can disrupt the natural balance of bacteria in the intestines, leading to loose stools. Even over-the-counter medicines or supplements can sometimes contribute to changes in digestion.

Chronic Conditions

When diarrhea lasts longer than a few days or keeps returning, it may be linked to a chronic condition. Inflammatory bowel disease (IBD), irritable bowel syndrome (IBS), and celiac disease are some of the conditions that can cause persistent diarrhea. Infections from parasites or bacteria may also lead to ongoing symptoms if untreated. Identifying the source is important for getting the right treatment and preventing complications.

When to Call a Doctor

Mild diarrhea usually improves without medical care, but there are situations where it’s best to see a doctor. Warning signs include diarrhea that lasts more than a few days, severe abdominal pain, high fever, or blood in the stool. Signs of dehydration, such as dizziness, dry mouth, or decreased urination, also require attention. For young children, older adults, or people with weakened immune systems, even short episodes of diarrhea can become more serious quickly.
