Select Ileo-Cecal Junction
The standard small bowel pH profile shows a gradual pH rise usually followed by a
plateau of the pH pattern. Transient pH drops may interrupt this profile but returns to
plateau of the pH pattern. Transient pH drops may interrupt this profile but returns to
their previous level within 10 minutes.
The pH drop associated with the capsule passing through the ICJ occurs after the
The pH drop associated with the capsule passing through the ICJ occurs after the
gradual sustained increase in pH through the small bowel. This drop of approximately
0.5–1.0 pH units usually occurs between 2–6 hours after gastric emptying.

Before ICJ, the pH rises smoothly and continuously in comparison to a more erratic
profile after ICJ.
