Fiber supplements are commonly used to soften stool, although the best source of dietary fiber is from the foods you eat. Psyllium husk fiber supplements are commonly used to soften stool and treat occasional constipation. Psyllium fiber should not be used to treat or prevent any medical condition without first talking with your doctor. Fiber supplements are not intended for long-term use unless directed by your doctor. In some instances, too much fiber can prevent proper absorption of nutrients.
Constipation
If you need a stool softener, you may be constipated. Constipation occurs when you lack enough fiber in your diet, causing your stools to become dry, hard and difficulty to pass. Everyone has different bowel movement patterns and you're considered constipated unless you have less than three bowel movements in one week, according to the National Digestive Diseases Information Clearinghouse. Being constipated can lead to further complications, such as anal fissures, tears in the anus that can cause bleeding during a bowel movement.
Types of Fiber
Fiber is the portion of plant-based foods that remains undigested by the human body and adds bulk and roughage to waste, according to MayoClinic.com. Soluble and insoluble fiber are the two types of fiber that help maintain regularity. Soluble fiber absorbs water in the digestive tract, creating a gel-like substance that softens the stool. Insoluble fiber does not absorb water, adding bulk but does not soften the stool. Psyllium fiber is mainly soluble fiber, which can effectively soften your stool. Before using psyllium fiber, talk with your doctor about the possible risks and benefits.
Dosing
The University of Maryland Medical Center states that the recommended dose of psyllium husk is a ½ to 2 tsp. daily, split into multiple doses. Psyllium is intended to be consumed with a full 8-oz. cup of water to prevent choking. Because psyllium absorbs water during digestion, if you don't drink enough fluids, you may perpetuate constipation. If you develop side effects, such as bloating, gas and cramping, reduce the amount of psyllium you're taking and slowly increase the amount over a week.
Considerations
Chronic constipation that does not improve with the use of fiber supplements may be a sign of a more serious condition, such as colon cancer, irritable bowel syndrome or an intestinal obstruction. If you have not had a bowel movement in three or more days, call your doctor immediately.
