Synopsis

Source of validity: Traditional
Rating (out of 5): 2

Methylcellulose is a bulk-forming laxative traditionally used to manage various digestive conditions, including constipation and, by extension, some forms of diverticular disease. The rationale behind its use in diverticulitis (specifically in cases of diverticulosis to prevent flare-ups, rather than in acute diverticulitis) is to soften stool and increase its bulk, theoretically reducing colonic pressure and the risk of new diverticula forming or existing ones becoming inflamed. This practice is rooted in longstanding clinical tradition, based on observations that high-fiber diets are associated with lower rates of diverticular disease.

However, scientific evidence directly supporting methylcellulose’s efficacy in preventing or treating diverticulitis is limited. Most clinical guidelines recommend a high-fiber diet or fiber supplementation after resolution of acute inflammation, but few randomized controlled trials specifically address methylcellulose as opposed to other fiber sources. The available studies on fiber supplementation for diverticular disease do not consistently distinguish between types of fiber or fiber supplements. Thus, while methylcellulose is commonly recommended by clinicians and included in practice guidelines, this is based more on tradition and extrapolation from general fiber studies rather than robust, direct scientific validation for diverticulitis itself.

In summary, the use of methylcellulose for diverticulitis is primarily justified by tradition and historical practice, with moderate but indirect supporting evidence extrapolated from broader fiber research, rather than condition-specific clinical trials.
