NCT02906293

Brief Summary

This study seeks to: Assess "normal" intestinal event rates for healthy subjects, to determine the effect of meal size on an individual's intestinal rate, and to determine whether there are differences between individuals in the fasting and post-prandial setting. The investigators hypothesize the following:

  1. 1.Fasting intestinal rate will be consistently less than 14 events per minute, similar to previously documented bowel sound frequency.
  2. 2.There will a uniform increase in intestinal rate in the immediate post-prandial setting. There will be direct correlation between maximal and average post-prandial intestinal rates and meal size. Likewise, meal size will correlate with time to baseline fasting intestinal rate.
  3. 3.Males and those with lower body mass index (BMI) will experience higher maximal and average post-prandial intestinal rates and shorter time to baseline fasting levels compared to females and those with higher BMI, respectively.

Conditions

Outcome Measures

Primary Outcomes (3)

  • Baseline fasting intestinal rate

    Prior to any oral intake, participants will record intestinal rate for 10 minutes

    10 minutes

  • Pre-meal intestinal rate

    30 minutes prior to eating lunch participants will secure the device and record for 10 minutes

  • Post-prandial intestinal rate

    Every 30 minutes for 5 hours after completion of meal

Study Arms (1)

Healthy Participants

Potential participants will self-refer.

Other: Abdominal acoustic measurement

Interventions

On Day 1 participants will record their intestinal rate at baseline fasting, pre-"small meal," and upon completion of the meal. On Day 2 participants will record their intestinal rate at baseline fasting, pre-"large meal," and upon completion of meal.
