Wireless Motility Capsule
Regional Transit Mapping
Whole-Gut Transit Time Analysis

A gastric emptying study, performed with a wireless motility capsule, is the only way to objectively measure how quickly, and in which specific segments, content moves through the gastrointestinal tract. It distinguishes presentations that look identical clinically but require different treatment.

Method
Ingestible wireless capsule, continuous regional data
Duration
Multi-day data collection, normal daily activity
Regions mapped
Gastric emptying, small bowel, colonic transit

The capsule captures continuous data as it travels through each region of the gut. The physiological changes it detects along the way allow precise identification of regional transit times, data that no breath test, imaging study, or symptom diary can generate.

What regional transit times reveal
Region
Clinical Significance
Gastric emptying
Normal: 2–5 hours
Delayed emptying drives nausea, early satiety, bloating. Rapid emptying produces dumping-type symptoms.
Small bowel transit
Normal: 3–8 hours
Rapid transit delivers excess substrate to the colon, worsening fermentation. Slow transit favors bacterial overgrowth.
Colonic transit
Normal: 18–59 hours
Colonic inertia versus normal-transit constipation requires different management. This distinction requires transit data.

Where the capsule points to a coordination problem rather than a transit problem, we follow up with anorectal manometry to confirm.

Commonly Ordered For

Patients with chronic constipation, nausea, early satiety, unexplained bloating, or bowel habits that haven't responded to dietary changes. Also indicated where SIBO findings suggest an underlying motility component explaining recurrence.
