Further study details as provided by Baylor College of Medicine:

Primary Outcome Measures:
  • Average daily abdominal pain frequency [ Time Frame: 9 days (2 dietary intervention periods) ]
    Comparisons of abdominal pain frequency (number of abdominal pain episodes per day) will be made between each two day dietary period spanning a 9 days.

Secondary Outcome Measures:
  • Abdominal pain severity [ Time Frame: 9 days (2 dietary intervention periods) ]
    The severity of abdominal pain episodes will be measured on a 1-10 (10 being most severe) ordinal scale. Average severity per abdominal pain episode during each two day dietary period will be compared over 9 days.

  • Hydrogen gas production [ Time Frame: 9 days (2 dietary intervention periods) ]
    Daily hydrogen gas production (parts per million) will be compared between each 2 day dietary intervention period over 9 days.

Estimated Enrollment: 40
Study Start Date: January 2011
Estimated Study Completion Date: December 2016
Estimated Primary Completion Date: December 2016 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: High fermentable substrate diet
High fermentable substrate diet provided for two days
Other: High fermentable substrate diet
Diet high in fermentable oligosaccharides, disaccharides, monosaccharides and polyols
Experimental: Low fermentable substrate diet
Low fermentable substrate diet provided for two days
Other: Low fermentable substrate diet
Diet low in fermentable oligosaccharides, disaccharides, monosaccharides, and polyols.

Detailed Description:

Many children experience stomach pain or discomfort at some point during their lives. Some children have belly discomfort frequently while others rarely have this problem. There have been very few studies to test treatments for recurrent stomach discomfort in children. Recently, studies in adults with recurrent stomach discomfort suggest that diet changes may help. Currently, we do not know if these same diets will work in children with the same problem.

In this study, two different diets will be provided (delivered) for two days with at least 5 days in between each provided diet. The child's symptoms will be recorded over the two days of each diet. Children will be asked to capture samples of their breath during the last day of the each two day delivered diet. Stool samples will also be collected.
