Diarrhea

Diarrhea is characterized by the frequent passage of loose or watery stools. It is a common symptom resulting from a disruption in the normal absorptive and secretory processes of the intestines, often leading to rapid transit of intestinal contents. Acute diarrhea is frequently caused by infections or dietary indiscretions, while chronic diarrhea (lasting over four weeks) is more indicative of underlying conditions like irritable bowel syndrome (IBS), inflammatory bowel disease (IBD), or microscopic colitis. The primary clinical concern with diarrhea is the potential for dehydration and electrolyte imbalance due to fluid loss.

Frequently asked questions

Is it possible to have constipation and diarrhea at the same time?
Yes, this is known as overflow diarrhea. It can happen with severe constipation, where a large mass of hard stool becomes impacted in the colon. Liquid stool from higher up can then leak around the blockage, presenting as watery diarrhea. It is also a common pattern in people with Irritable Bowel Syndrome with mixed bowel habits (IBS-M).

When should I be concerned about traveler's diarrhea?
Traveler's diarrhea is common and usually resolves on its own. You should seek medical care if the diarrhea is severe, bloody, accompanied by a high fever, or if it doesn't resolve within a few days of returning home.
