Bulk-forming Laxatives

Summary
Psyllium and methylcellulose are two common bulk-forming laxatives. These laxatives work by absorbing water, which softens stool and increases stool bulk. This increased stool bulk stimulates more frequent bowel movements. Too much bulk-forming laxative can result in diarrhea.
