Soluble fiber can help reduce bouts of chronic diarrhea. Diarrhea occurs when there is too much water in the colon, as stated by WebMD.com. Soluble fiber helps absorb some of that water to aid in producing more solid stools.
Speak with a health care professional regarding the ideal amount of fiber, including soluble fiber, to consume for your specific condition. Too much fiber can actually lead to frequent bouts of diarrhea, says EverydayHealth.
The ideal solution is balancing the different types of fiber into your daily diet. Those with food allergies to high-fiber foods, such as wheat, nuts and apples, can get the right amount of fiber in their diet by taking a natural fiber supplement.
