Methylcellulose is a semi-synthetic, non-digestible fiber commonly used as a bulk-forming laxative to support the rectum and overall lower gastrointestinal tract, particularly in the management of constipation. Its use is well-established in both clinical practice and supported by scientific studies. Methylcellulose works by absorbing water in the intestines, increasing stool bulk and moisture, which in turn facilitates easier passage of stool and promotes regular bowel movements. This mechanism helps reduce straining during defecation, an important factor in maintaining rectal health and preventing conditions such as hemorrhoids, anal fissures, and rectal prolapse.

The efficacy of methylcellulose as a laxative is supported by clinical trials and systematic reviews. For example, a review published in the American Journal of Gastroenterology (2014) confirmed that bulk-forming laxatives, including methylcellulose, are effective and safe for treating chronic constipation. The U.S. Food and Drug Administration (FDA) has also approved methylcellulose for over-the-counter use as a bulk-forming laxative, further underscoring its scientific validation for this purpose.

Methylcellulose is generally well-tolerated, with minimal side effects compared to stimulant laxatives. It does not ferment in the gut, so it typically produces less gas and bloating than some other fiber supplements. In summary, there is robust scientific evidence supporting the use of methylcellulose for supporting rectal and lower gastrointestinal function, particularly in the management of constipation.
