What type of laxative works by increasing stool size to promote bowel movement?

The type of laxative that works by increasing stool size to promote bowel movement is bulk-forming laxatives. These laxatives contain natural or synthetic fibers that absorb water in the intestines, leading to an increase in stool bulk. As the stool expands, it triggers the bowel to contract, promoting a natural urge to have a bowel movement.

Bulk-forming laxatives are considered a gentle form of laxative and are often recommended for individuals experiencing mild constipation. They are generally safe for long-term use and can be an effective option for maintaining regularity in the digestive system.

Other laxative types function differently. For instance, saline laxatives draw water into the intestines to soften stool, while stool softeners work by allowing water and fats to get into the stool, making it easier to pass. Stimulant laxatives increase bowel activity directly by irritating the intestinal lining. Each has its specific use, but bulk-forming laxatives are unique in their function of increasing stool mass to stimulate bowel movements.
