Eating marshmallows reduces ileostomy output: a randomized crossover trial

Area of Science:

• Gastroenterology
• Surgical Patient Care

Background:

• Anecdotal evidence suggests marshmallows may reduce ileostomy effluent.
• Gelatine in marshmallows might thicken small bowel fluid, but clinical evidence is lacking.

Purpose of the Study:

• To investigate the effectiveness of marshmallows in reducing ileostomy output volume and altering effluent consistency.

Main Methods:

• A randomized crossover trial involving adult ileostomates.
• Participants consumed three marshmallows three times daily for one week, followed by a control week without marshmallows, with a 2-day washout period.
• Ileostomy output was measured, and a questionnaire assessed subjective patient experience.

Main Results:

• A median reduction of 75 ml in daily ileostomy output was observed during the marshmallow intervention week (P = 0.0054).
• 71% of participants (20/28) reported reduced ileostomy output, and 71% (20/28) noted thicker effluent.
• Participants also reported fewer daily ileostomy bag changes (median 5 vs. 6, P = 0.0255).

Conclusions:

• Consumption of marshmallows results in a statistically significant, albeit small, reduction in ileostomy output.
• The findings support the use of marshmallows for managing ileostomy effluent consistency and volume.
