Diarrhea is a common digestive condition characterized by loose, watery stools occurring more frequently than usual. While it is often mild and resolves on its own, persistent or severe diarrhea can lead to dehydration and nutrient loss, requiring medical attention. Understanding its causes, symptoms, and treatment options can help manage and prevent complications.
1. Causes of Diarrhea
Diarrhea can be triggered by various factors, including infections, dietary habits, and underlying health conditions.
Infectious Causes

Parasitic Infections – Protozoans like Giardia and Entamoeba histolytica can cause prolonged diarrhea.
Non-Infectious Causes
-
Food Intolerances – Conditions like lactose intolerance can lead to diarrhea after consuming dairy.
-
Medications – Antibiotics, laxatives, and certain drugs may disrupt gut bacteria, causing diarrhea.
-
Digestive Disorders – Chronic conditions like irritable bowel syndrome (IBS), Crohn’s disease, and celiac disease can lead to persistent diarrhea.
-
Excessive Sugar or Artificial Sweeteners – High intake of fructose or sorbitol can cause digestive distress.
