10 Common Causes of Diarrhea


After a particularly fatty feast or bout of the flu, diarrhea often rears its gassy, bloated, uncomfortable presence. A spell of it often consists of loose, watery bowel movements that come on suddenly and leave you hesitant to be far from a bathroom.

Typically, diarrhea occurs due to a virus, such as the stomach flu, in the digestive system, lasting no more than a few days. However, long-term or frequent affliction can indicate other chronic diseases within the large intestine.

Here are the ten most common causes of diarrhea…

1. Consuming foods that upset the digestive system

2. Food poisoning or bacteria in the digestive system

3. Food allergies—commonly dairy or gluten

4. Abuse of laxatives

5. Medications—such as antibiotics

6. Alcohol abuse

7. Intestinal conditions—like Crohn’s disease or ulcerative colitis

8. Malabsorption—or the inability to absorb certain nutrients from food

9. Diabetes or Hyperthyroidism

10. Cancer or certain types of cancer treatments—like radiation
