Bulk-forming laxatives

Definition

Bulk-forming laxatives are substances that increase the bulk of stool by absorbing water, which helps to stimulate bowel movements and alleviate constipation. These laxatives are often derived from natural fibers and work by creating a gel-like consistency in the intestines, making it easier for stool to pass through. They are considered one of the safest and most effective types of laxatives, promoting regularity while also contributing to overall digestive health.
