Can too much bile cause runny stool?

Yes, excessive bile can lead to runny stool, a condition known as bile acid diarrhea. When the intestines are overwhelmed by high levels of bile acids, it can disrupt the normal absorption of fats and water, resulting in loose or watery stools. This can occur in conditions such as bile acid malabsorption or after certain surgeries involving the intestines. If you experience consistent issues, it's important to consult a healthcare professional for proper evaluation and management.
