Can Psyllium Husk Cause Diarrhea?

Psyllium husk is commonly used as a dietary supplement to promote regular bowel movements and relieve constipation due to its high fiber content. However, when taken in excessive amounts or if an individual’s body isn’t accustomed to high-fiber intake, psyllium husk can potentially lead to gastrointestinal issues, including diarrhea.

Psyllium husk contains soluble fiber, which absorbs water and forms a gel-like substance in the intestines. This bulk-forming effect aids in softening the stool and promoting regular bowel movements, typically helping to alleviate constipation.

However, if psyllium husk is taken without sufficient water intake or if someone suddenly increases their fiber intake significantly, it can lead to an imbalance in the digestive system. This imbalance can cause excessive water absorption by the fiber, resulting in loose or watery stools, which may lead to diarrhea.

To avoid potential digestive issues when taking psyllium husk or any fiber supplement:

  • Start with a small dose: Begin with a lower dose and gradually increase it over time to allow your body to adjust to the added fiber.
  • Stay hydrated: Drink plenty of water throughout the day when consuming psyllium husk or any fiber supplement. Adequate hydration is essential to help the fiber move smoothly through the digestive tract.
  • Follow recommended dosages: Stick to the recommended dosage as indicated on the product label or as advised by a healthcare professional.
  • Monitor your body’s response: Pay attention to how your body reacts to psyllium husk. If you experience diarrhea or any discomfort, reduce the dosage or stop using it temporarily.
  • Maintain a balanced diet: Ensure your diet includes a variety of fiber sources, including fruits, vegetables, and whole grains, along with psyllium husk, to avoid overloading your system with one type of fiber.

If diarrhea persists or becomes severe despite adjustments in psyllium husk intake or hydration, it’s advisable to seek advice from a healthcare professional. They can provide guidance on managing your fiber intake and address any underlying digestive issues.
