Psyllium for Diarrhea Management

Mechanism and Effectiveness

• Psyllium is a soluble fiber that increases stool weight by absorbing water and adding bulk, which helps normalize stool consistency in diarrhea 2, 3
• Among evaluated fiber supplements, only psyllium has demonstrated consistent effectiveness for improving bowel function, with very limited and uncertain data on other fiber types such as bran and inulin 1, 2
• Psyllium works by increasing stool weight through water absorption and bacterial fermentation, which helps regulate transit time and improve stool consistency in diarrhea 3, 4

Dosing and Administration

• Psyllium supplements should be taken with at least 8-10 ounces of fluid to ensure proper hydration and effectiveness 2, 5

Potential Side Effects and Precautions

• Flatulence is a commonly observed side effect with fiber supplementation, including psyllium 1, 2
• Adequate hydration is essential when using psyllium to prevent potential constipation or blockage 2, 3
